Terms of Service

Agreement to these Terms

These Terms of Service (the “Terms”) are a binding agreement between you and Ado Systems about your use of Hisab - our point-of-sale, inventory, invoicing, payments, accounting, reporting and online-storefront platform - together with our websites, the Hisab mobile app and related services (together, the “Service”).

By creating an account, signing in or otherwise using the Service, you agree to these Terms and to our Privacy Policy, which explains how we handle personal information and forms part of this agreement. If you use Hisab for a business, you confirm that you are allowed to bind that business, and “you” means both you and that business.

These Terms apply to everyone who signs in, including staff whose accounts an Owner creates and visitors who try the shared demo. If you do not agree to them, do not use the Service.

Who we are

Hisab is built and operated by Ado Systems (also written “Adosystems”; “Hisab”, “we”, “us”, “our”), based in Addis Ababa, Ethiopia. Hisab is software for Ethiopian businesses - shops and retailers, wholesalers, importers, exporters, fuel stations, service businesses and anyone who simply keeps a cash book - to sell, track stock, invoice, record payments, keep double-entry books, read reports and reach buyers online.

You can reach us at any time at hisab@adosystems.com. Notices we give you under these Terms may be sent to the email address on your account or shown within the Service.

Definitions

To keep the rest of this document short, a few words have specific meanings:

Eligibility & your account

To use Hisab you must be at least 18 years old and able to enter a binding contract. Hisab does not check ages, so by signing up you confirm that you meet this requirement.

Signing up

To create an Account you give us your email address, a password of at least 6 characters, a phone number (required, 9 to 15 digits) and your name, and you name your first Business and choose its type. Please give accurate details. We check your email address by sending a 6-digit code, which you must enter before you can sign in; each code expires after 30 minutes. We do not verify phone numbers by text message.

There is no in-app way yet to change your name, phone number or email address. Email us and we will help.

Keeping your account secure

You are responsible for keeping your password private and for what is done with your sign-in details. Use a password you don’t use anywhere else. A sign-in lasts up to 7 days, and signing out clears it from that device only. If you think someone else has your password or is signed in as you, tell us at once at hisab@adosystems.com, and reset your password with “Forgot password” on the Hisab website, which signs out the devices signed in at that moment. We are not liable for losses caused by your failure to keep your sign-in details secure, except where the loss results from a fault in the Service.

One person, one Account

Each Account is for one person. Don’t share a login: add each person as Staff, so their actions are attributed to them and their permissions apply. One Account can belong to several Businesses - for example as Owner of one and staff in another. We may refuse or remove Accounts that are fraudulent, impersonate someone or break these Terms.

The shared demo

Where we offer a one-tap demo, every visitor signs in to the same demo businesses as the same demo owner. Anything you type there can be seen and changed by other visitors, so never enter real or personal information. Demo businesses, people and figures are made up for illustration, and we may change or remove them at any time. Previews in the demo, such as viewing the app as another role or plan, only change what your screen shows.

The Hisab service

Hisab gives a Business tools for its day-to-day work. Which tools you see depends on your business type, your Plan and your permissions. Today they include:

• Point of sale - a till with discounts, VAT, several payment methods, returns, till shifts and cash-up, camera barcode scanning in the web app, and receipts by text message.
• Inventory - products and pack sizes, stock movements, batches with expiry dates, costing by FIFO, LIFO, FEFO, weighted average, specific lot, standard cost or retail ratio, and reorder and expiry alerts.
• Customers, invoices and payments - credit sales with numbered invoices, credit limits and payment terms, payments split across accounts or spread over several invoices, advance credit, and invoice links you can share.
• Purchasing and spending - suppliers, purchase orders and goods received, supplier payments, expenses, cash books, and transfers between your own cash and bank accounts.
• Accounting and reports - a chart of accounts and a double-entry general ledger that sales, invoices, payments, purchases, expenses and other documents post to automatically, manual journals, and reports such as profit and loss, balance sheet, cash flow, sales, VAT, inventory and ledger.
• Import and export - import shipments with landed-cost and customs estimates and foreign-currency bank requests; export orders with FOB, CFR and CIF cost building and export expenses.
• Fuel stations - tanks, calibration charts and dipstick readings compared with the stock in your books.
• Trade record books - for example prescriptions, lens orders, repairs, rentals, quotes, deliveries, insurance claims and compliance logs, depending on your business type.
• Storefront and website - a public shop page that takes orders and, on Growth, a multi-page website, a contact form and your own domain.
• Team and control - staff roles and permissions, an activity log, past-dated entries for loading earlier records, and several Businesses under one login.

We keep improving Hisab. We may add, change or remove features, and set or adjust technical limits such as upload sizes or how often an action can be repeated. If a change takes away a main Growth feature you have paid for, we will tell you in reasonable time first.

Plans, pricing & payment

Hisab has two plans, Starter and Growth, and each Business has its own plan. These Terms set out what each plan includes and its limits; our pricing page shows the current Growth price. Descriptions of the plans anywhere else - on the pricing page, on Plan & billing or in our marketing - are short summaries and are not part of these Terms, and where they differ, these Terms apply. Prices are in Ethiopian birr (Br / ETB).

Starter

Starter is free and has no end date. It includes the tools described under The Hisab service apart from the Growth features below, one Business that you own and, currently, up to 3 people in each Business - the Owner included, and frozen members count too. We may change these limits as described under “Price and plan changes” below.

Growth

Growth adds unlimited staff, a multi-page website with Home, About and Contact pages, a contact form for shoppers, your own custom domain, and owning more than one Business: you can create another Business only while every Business you already own is on Growth. Each new Business starts on Starter.

Growth is free for each Business’s first year

Each Business can have Growth free for 365 days. The Owner, or someone they allow to manage Plan & billing, switches it on from the Plan & billing page, and it starts straight away - no card, no payment and nothing for us to confirm. The year counts from the day it is switched on, not from the day you signed up.

• Each Business gets the free year once. It belongs to the Business, not to you, so each Business you own can have its own free year. The free year is for genuine use: we may refuse it, or move a Business back to Starter, where Accounts or Businesses are created or recreated mainly to get further free years.
• If you switch back to Starter during the free year, Growth stops at once. You can switch it back on free until the original end date - the year does not pause or restart.
• If we switch on paid Growth for a Business during its free year - for example because you paid early - the free year ends that day and can’t be taken back later.
• When the year ends, the Business goes back to Starter automatically and nothing is charged. We don’t currently send a reminder, so keep an eye on the end date shown on Plan & billing.
• After its free year, Growth is a paid plan for that Business, as described below.
• A Business that was already on paid Growth before 15 October 2026 has not used its free year. We won’t move it back to Starter before the end of the time it has paid for. It can take the free year later, but it must switch to Starter first, which ends any paid time at once, and that time isn’t refunded.

Paying for Growth after the free year

After the free year, Growth costs the price on our pricing page - currently Br 2,499 per shop (Business) per month. To ask for it:

1. pay the amount to one of the accounts Hisab lists on the Plan & billing page (for example a bank or Telebirr account) - never to any other account, and if none are listed, contact us before paying;
2. enter the payment reference (transaction number) on Plan & billing; and
3. wait while we check the payment. Growth switches on only after a Hisab operator confirms it by hand. We try to do this promptly but can’t promise a time, and if we can’t match a payment we won’t switch Growth on until it is resolved.

There is no automatic renewal: Hisab keeps no card or payment details on file and never charges you on its own. Each payment covers one month for one Business, counted from the day we switch Growth on. Paid Growth then stays on until you switch to Starter or we move the Business back - the app doesn’t end it after a month. To pay for a further month, pay a listed account the same way and email the payment reference to hisab@adosystems.com, because Plan & billing can’t take a new reference while Growth is on. If a month goes unpaid, we will email the Owner before we move the Business back to Starter, and we won’t charge for time Growth stayed on before we asked you to pay. Any charges your bank or mobile-money provider makes for sending a payment are yours.

Hisab doesn’t issue a receipt or invoice for a Growth payment automatically. If you need one for your books, email us with the payment reference and we will send it.

Cancelling and refunds

• You can switch a Business back to Starter at any time from Plan & billing. It takes effect immediately, not at the end of a paid month.
• Payments for paid Growth are not refundable, including for the rest of a month after you cancel, except where the law requires it or we agree otherwise - for example if you paid twice by mistake, or we never switched Growth on for a payment you made. Contact us if something has gone wrong.

Price and plan changes

We may change prices, plans, features and limits, and we show current prices on the pricing page. A price change applies to payments made after it, not to a month you have already paid for, and a free year that has already started keeps its end date. Before a change that is materially worse for you - such as a price rise or a cut to Starter’s limits - takes effect, we will email the Owner of each Business affected at least 30 days in advance, unless the law or a security need requires a faster change.

When Growth ends

When a Business leaves Growth - because its free year ends, you cancel, or we move it back to Starter - nothing is deleted:

• people already in the Business keep their access, but you can’t add anyone while you are at or over the Starter limit;
• other Businesses you own stay, but you can’t create new ones;
• your website pages and contact form stop showing to the public; what you wrote is kept and shows again if Growth comes back, and messages you have already received stay readable;
• a connected custom domain is not disconnected automatically - see Custom domains.

Within your Business, only the Owner and anyone the Owner allows to manage Plan & billing can change its plan, and you are responsible for their choices; Hisab’s operator can also switch it, as described in this section and under How we access your data. Staff who can view reports can also see the current plan, the Growth price and the accounts to pay.

Taxes & your records

Running a business comes with legal duties - registering, charging and paying tax, issuing proper receipts and invoices, and keeping books. Those duties are yours, not ours, even when Hisab helps with the numbers.

• Hisab works out VAT on sales only when you switch it on and set the rate, and its import tools estimate customs duty, surtax, VAT and withholding from default rates you can change. Check every figure against the rules that apply to you.
• Hisab does not file returns, declarations or payments with any tax or customs authority, and it is not connected to one.
• Hisab does not claim to be approved by any tax authority as a sales register, fiscal device or electronic-invoicing system. If the law requires you to use one, you must use it as well.
• Invoice numbers follow Hisab’s own sequence (INV-year-number), using the Gregorian calendar year in UTC at the moment the invoice is created. That year can differ from the Ethiopian calendar year, your fiscal year, your local date in the first hours of 1 January, or a past date you give the invoice. We don’t promise that this meets any official numbering rule.
• You must keep your records for as long as the law requires. Some deletions in Hisab are permanent, so export what you need first.

Changing and deleting records

You can correct and delete many records, and some deletions can’t be undone:

• Deleting a product only hides it; its history stays.
• An invoice can be edited only while it has no payment recorded and is not void, and an invoice with a payment can’t be voided. Voiding returns the goods to stock, reverses its ledger entries and keeps the invoice marked “void”.
• A voided invoice, a purchase order, a cash book, an export order and some other records can be deleted permanently, together with their stock movements and ledger entries. Some of these deletions need a permission only the Owner has by default, and we may not be able to restore what you delete.
• You can enter sales, expenses, payments, stock counts and other records with past dates, and reports and the ledger use the dates you enter. Make sure they are right.

Your books are only as accurate as what goes into them. Hisab posts most documents to your ledger automatically, but if an account those postings need is missing from your chart of accounts, the entry may not be made. Built-in rules - for example the “heating” expense a fuel station can choose to have booked, for a share of the extra litres it sets when a delivery brings more than was ordered - rest on fixed assumptions. Review and reconcile your books regularly.

Your data & content

Your Business Data is yours. As between you and us, you own the records and content you put into Hisab, and we claim no ownership over them. We never sell your Business Data and we don’t use it for advertising.

You give us a limited, non-exclusive licence to host, store, copy, process, transmit and display your Business Data only as needed to provide, support and secure the Service for you - for example, to show your storefront and shared links to the people you choose - and as our Privacy Policy describes. This licence ends when your data is deleted from our systems, apart from anything we must keep by law and copies of our databases on our servers, which may keep deleted information for some time.

Personal information you enter

When you enter information about other people - customers, suppliers, staff, shoppers, patients or drivers - you are responsible for having a lawful reason to collect and keep it, for telling them how it is used where the law requires, and for handling their requests. This matters most for sensitive details some trades keep, such as prescriptions, eye measurements or background checks. We handle that information on your behalf, as our Privacy Policy describes.

Uploaded images

You can upload JPG, PNG, WEBP or GIF images of up to 8 MB - product photos, your logo, storefront pictures and payment slips attached to supplier payments. Uploaded images are not private: images from every Business are stored together on our server, each at a long random web address that isn’t listed anywhere - but anyone who has that address, including people outside your Business, can open the image without signing in. Removing an image from a page does not delete the file. Don’t upload anything you need to keep confidential, such as a payment slip that shows account numbers, and upload only images you have the right to use.

Backups and exports

We don’t promise backups you can rely on to restore your data. Copies of our databases may be made on our servers - for example before an update - but they exist to run the Service, not as a backup service for you. Export important records regularly: reports download as Excel files or print to PDF, invoices can be printed or saved as PDF, and a period workbook can be downloaded from the book report. There is no one-click export of a whole Business yet; if you need a full copy, ask us.

Shared links & SMS receipts

Some features send information outside Hisab. You decide who receives it, and you are responsible for that choice.

Invoice links

Sharing a customer invoice creates a link. Anyone who has the link can open the invoice without signing in. It shows the invoice number and date, the customer’s name, the items, prices, discount, VAT, totals, amount paid and balance, and your shop’s name, logo, phone, address and VAT TIN - but not your costs or other customers. The link always shows the invoice as it is now, including later edits, payments and a “void” status. It does not expire and can’t currently be switched off in the app; it stops working only if the voided invoice is permanently deleted. When your own domain is connected and verified, invoice links use it.

Report links

Sharing a report saves a frozen copy of the figures on your screen at that moment and creates a link anyone can open, branded with your shop’s name and logo. Hisab doesn’t recalculate or check a shared report. Report links don’t expire and can’t currently be withdrawn or listed in the app. Anyone in your Business who can view reports can create one.

Both kinds of page ask search engines not to list them, but a link can be forwarded, so share links only with people who should see the document.

SMS receipts

Staff who can sell can text a receipt - your shop’s name, the receipt code, the total and VAT - to a phone number they type in. The text goes through our SMS delivery provider. Send receipts only to customers who want them, and never use this feature for marketing or unwanted messages.

Storefront & your shoppers

Every Business can have a public storefront page on Hisab’s website. Your shop’s name, business type, logo, contact phone and address can be seen publicly as soon as you enter them, even before you publish; on Growth, so can your tagline, About text, hero image, website page text and connected domain. Your products appear only after you switch Publish on, and you can switch it off at any time.

Once published, the storefront lists every active product with its name, category, selling price, unit, pack price, photo and whether it is in stock - never your costs, stock counts or suppliers. A product priced at 0 shows as “Price on request”, and one that is out of stock shows as “Sold out”.

Orders and messages

A shopper places an order by giving their name, phone number, an optional note and the items they want. Prices come from your product list, not from the shopper’s screen. There is no online payment: the shopper pays you on delivery or pickup. An order never changes your stock or your books by itself, even when you mark it fulfilled: ring the sale up at the till to record it and take the items out of stock. Hisab does not alert you or the shopper by email or text, so check your Orders page. On Growth, shoppers can also send you messages through a contact form.

You are the seller

For anything sold or offered through your storefront, you are the seller, not Hisab, and Hisab is not a party to any sale between you and a shopper. You are responsible for your listings, descriptions, images, prices and availability; for confirming, delivering and fulfilling orders; for returns, refunds and customer service; and for the consumer-protection, pricing, product-safety and other laws that apply to what you sell.

You are also responsible for your shoppers’ personal information. Your storefront doesn’t show a privacy notice for your shop, so if the law requires you to tell shoppers how you use their details, do so yourself - for example in your About text (shown on Growth only). Text you write is shown as plain text, and images you link from other websites are your responsibility. To limit spam, we cap how many orders and messages one connection can send each minute.

Custom domains

On Growth, you can show your shop on your own web address, such as yourshop.com. By default the Owner and Manager connect, change and check a domain themselves from the Storefront page. This is how it works:

• You must own the domain, or have its owner’s permission to use it, and keep its registration paid and its DNS records correct. Hisab does not check ownership when you save a domain. Each domain can belong to only one shop, and Hisab’s own domains and our hosting provider’s domains can’t be used.
• When you save a domain, Hisab tries to attach it to our hosting provider (currently Vercel) and, for a root domain such as yourshop.com, to attach www.yourshop.com as a permanent redirect to it; the Storefront page tries again each time it checks the domain. This can fail without the page saying so, so if your domain still doesn’t open your shop once its records are right, contact us.
• The Storefront page shows the exact DNS records to add where you bought the domain: for a root domain, an A record and a CNAME for www; for a subdomain such as shop.yourshop.com, one CNAME; and, in either case, a TXT record if our hosting provider asks for proof of ownership. You add them at your registrar; we can’t change your DNS for you.
• “Check again” checks whether the domain is live. That can take from a few minutes to 24 hours or more, and we can’t promise a time. Our hosting provider issues the security certificate (HTTPS) once the records are right.
• Hisab checks a domain only when it is saved or when the Storefront page checks it - we don’t watch it for you. If your DNS or registration lapses, your domain will stop working.

What appears on your domain

Once connected, your domain shows your storefront - the full website while you are on Growth - and your invoice and report links use it. Your staff can sign in there to a version of Hisab branded with your shop’s name and logo. They still use their Hisab Accounts, their sign-in details go to Hisab, and these Terms and our Privacy Policy still apply; those pages may also open on your domain. A domain never gives anyone access to your Business: only its members can see its records. You are responsible for everything published under your domain.

Changing or removing a domain

If you change or clear your domain, Hisab stops linking it to your shop, but it is not detached from our hosting provider automatically. Remove the DNS records you no longer want pointing at us; while they remain, visitors may see Hisab’s own homepage.

If your Business leaves Growth, a connected domain is not disconnected: while its DNS still points at us, it can keep showing your shop’s basic page and your invoice and report links. On Starter you can’t change or remove the domain from the dashboard, so remove its DNS records at your registrar, or contact us and we will remove it from your shop by hand.

We may refuse or remove a domain that infringes someone else’s rights or breaks these Terms; we do this by hand, not instantly. If another shop has attached a domain that belongs to you, contact us.

Staff, roles & the activity log

Each Business has one Owner, who always has full access and can’t be frozen or removed. Ownership can’t currently be transferred in the app; contact us if you need to change it.

Control of a Business

We treat the Owner shown in Hisab as authorised to act for the Business. We change the Owner only on documentary evidence - such as a trade licence, a company resolution, a power of attorney or a court order - and we may hold a change while a dispute about it is open. Staff can’t leave a Business on their own in the app: ask its Owner, or us, to remove you.

Adding staff

The Owner, and anyone allowed to manage staff (by default the Manager), can add people to a Business, up to the limit of its plan. The person adding them enters their email, an optional name and phone number, a role and, for someone new to Hisab, a first password. Hisab doesn’t send an invitation: the new person confirms their email with a code the first time they sign in, and should then set their own password with “Forgot password” on the Hisab website. If the email already belongs to a Hisab Account, that person is added straight away, and whoever added them can see that Account’s name and phone number. Only add people who have agreed to join, and make sure they know these Terms and our Privacy Policy apply to them.

Roles and permissions

Every member has a role - for example Manager, Cashier, Inventory Clerk or Accountant, or a role suited to your trade, such as Pharmacist or Export Manager. The Owner can also give individual staff extra permissions, such as editing or deleting posted accounting records or reading the activity log, and can set who may create, view, change or delete each kind of document, for a whole role or for one person. Only the Owner - and Hisab’s support account, if you add it with a role that manages staff - can change a member’s access, freeze or remove them.

Permissions are controls you set. You are responsible for choosing them, for what your staff do in your Business, and for removing access when someone leaves. Some till switches, such as allowing past-dated sales or cash-out, only change what the till screen offers and are not a security control. Role names and descriptions are labels: Hisab does not check professional licences, such as a pharmacist’s.

Freezing and removing members

Freezing blocks a member from the Business at once while keeping their role and history, so you can reactivate them later. Removing takes them out of the Business. Either way, their Hisab Account stays open, they keep access to any other Business they belong to, and the records they created stay attributed to them.

The activity log

Each Business keeps an activity log of the changes made in it: who did what and when, in which role, what changed (old and new values), amounts, refused attempts and the IP address, plus a short device description such as “Chrome on Windows” for sign-ins and refused attempts. It also notes each member’s first sign-in of the day, wrong-password attempts on members’ Accounts, storefront orders and messages (shown as “A customer”, with the shopper’s IP address) and any plan change made by Hisab. Passwords, PINs and similar secrets are masked. The log records changes, not what people view.

The Owner can see the whole log and can let others see it; everyone in the Business can see who added each record. Detailed entries older than 24 months are cleared when the Activity page is next opened, while the note of who added or last changed each record is kept as long as the Business exists. Because the log monitors your staff, you must tell them about it and use it lawfully. It helps you see what happened, but we don’t guarantee that it captures everything.

How we access your data

We treat your Business Data as confidential. Hisab operators have no standing access to the inside of any Business: the app opens a Business’s records only for its members, and that applies to our operators too.

The operator console we use to run Hisab does not open your Business’s records. It shows the list of Accounts (name, email, phone number, whether the email is confirmed, number of Businesses and join date); the list of Businesses (name, web name, type, status, the Owner’s name and email, number of members, plan and free-year end date); and the platform security log of sign-ins, failed sign-ins, password resets, new Businesses and plan requests, with IP addresses, browser details and any payment reference you enter. From the console, an operator can only switch a Business between Starter and Growth, and when we do, it appears in your activity log as coming from Hisab. We will update these Terms before we give the console any tool that opens a Business’s records.

We will look inside a Business only when one of these applies:

1. an Owner adds our support account as a member to help with something. While it is a member it can do what the role you give it allows, it is not held back by the per-person or per-role access settings, and with a role that manages staff it can change access and freeze or remove members as you can. Remove it when the job is done;
2. it is strictly necessary to investigate or fix a serious technical or security problem; or
3. the law requires it.

The people at Ado Systems who maintain our servers can technically reach the data stored on them. They may do so only for the reasons above and to operate, maintain and repair the Service, using the narrowest access for the shortest time needed.

Where the law allows, we will tell the Owner before we disclose Business Data to an authority, or promptly after we have looked inside a Business to fix a problem, and we will disclose only what is required.

Acceptable use

Use Hisab lawfully and fairly. In particular, you must not:

• break any law, or use Hisab to sell prohibited goods, launder money, evade tax, or deceive or defraud anyone;
• record false sales, invoices or accounts to mislead a tax authority, bank, investor, customer or anyone else;
• upload or publish content that is unlawful, infringing or deceptive, or that you have no right to use, or attach a domain you don’t own or aren’t allowed to use;
• access a Business you are not a member of, or try to get around sign-in, permissions, plan limits or the separation between Businesses;
• probe, scan, overload or disrupt the Service, get around its rate limits, or introduce malware or harmful code;
• scrape the Service with bots, or use shared links, the storefront or SMS receipts to send spam or unwanted messages;
• put real or personal information into the shared demo, or use it to disrupt other visitors;
• copy, resell or sublicense the Service, or reverse-engineer or decompile it, except where the law expressly allows.

Running your own shop under your own name, logo and domain with Hisab’s storefront and custom-domain features is allowed - that is what they are for. Offering Hisab to others as your own product is not, unless we agree in writing.

If you find a security weakness, please tell us at hisab@adosystems.com and don’t use or share it. You are responsible for how your staff use Hisab through your Business.

Third-party services

Hisab relies on other companies to run. Today they include:

• a cloud infrastructure provider that hosts our servers and the databases holding your Business Data;
• Vercel, which hosts our website and web app, serves storefronts on custom domains and issues their security certificates;
• Resend, which delivers our sign-up and password-reset emails and receives email sent to our own addresses, which we pass to our team on Telegram;
• an SMS delivery provider for text-message receipts;
• Let’s Encrypt, which issues the security certificates for our servers; and
• Cloudflare, which counts visits to Hisab’s own website, without cookies, so we can see how it is used and how fast it loads - never on a shop’s own domain.

Hisab does not use a payment processor. Payments to Hisab, and payments between you and your customers, go through your own bank or mobile-money provider under its own terms, and your domain registrar’s terms apply to your domain. We are not responsible for services we don’t control, and an outage at one of them can affect Hisab. We may change providers; our Privacy Policy explains what they receive.

Intellectual property

The Service itself - Hisab’s software, design, user interface, the “Hisab” name and logo, and all related intellectual property - belongs to Ado Systems and its licensors. We give you a limited, non-exclusive, non-transferable, revocable licence to use the Service for your own business while your Account is in good standing. Nothing here transfers any of our intellectual property to you.

Your shop’s name, logo, product photos and the content you publish stay yours. You let us display them as needed to run your storefront, website, shared links and custom domain.

If you send us feedback or suggestions, you give us a perpetual, royalty-free right to use them to improve the Service, without obligation to you.

Availability, offline & support

We aim to keep Hisab available and fast, but we provide it on a reasonable-efforts basis and don’t guarantee that it will be uninterrupted, error-free or available at any particular time. We may carry out maintenance, sometimes at short notice to protect the Service.

Selling offline

In the web app, the till can keep selling when the internet drops: a sale that can’t reach us is held in that browser and sent automatically when the connection returns or the till next opens. Hisab ignores a sale it has already received, so a sale isn’t counted twice. Please note:

• an offline sale gets its receipt number when it syncs and is recorded with the time it reaches us, not the time it was made, so check its date;
• held sales belong to that browser, not to a person: they stay after signing out and are sent under whoever is signed in when they sync. Each one goes only to the Business it was rung up in - a sale held for another Business waits on the device until that Business is opened there;
• when held sales reach us, each is checked again. A sale we refuse - for example because stock ran out in the meantime, it is below landed cost or it would go over a customer’s credit limit - is not recorded, but it stays on the device with the reason so the cashier can retry it or discard it;
• held sales are lost if the browser’s data is cleared or the device is lost before they sync, and we can’t recover them; and
• the Hisab mobile app does not hold sales offline, even where a screen says “Offline ready” or “Saved offline”: if it can’t save a sale, the sale is not kept. It and most other features - invoices, reports, settings and the storefront - need an internet connection.

Support

We provide support mainly by email at hisab@adosystems.com. We try to respond promptly, but we don’t guarantee a response time unless agreed separately in writing. The Hisab mobile app lets you sign in, sell and use many day-to-day screens, such as products, customers, expenses, staff, trade records and reports; you create Accounts, reset passwords and manage billing on the Hisab website.

Suspension & termination

You can stop using Hisab at any time. Switching to Starter or simply not signing in does not close or delete anything: nothing in Hisab deletes a Business automatically because it is inactive or changes plan. There is no self-service way yet to close an Account or a Business. To do that, email us from the Account’s email address; we may ask you to confirm who you are first. An Owner must hand over or close each Business they own before we close their Account.

We may suspend or end your access, in whole or in part, or move a Business back to Starter, if you seriously breach these Terms, don’t pay for a further month of Growth after we have asked you to, use the Service in a way that risks harm to others or to Hisab, or where the law requires it. Where it is reasonable and lawful, we will tell you first and give you a chance to put things right. An Owner can also freeze or remove staff at any time (see Staff, roles & the activity log).

If we stop offering Hisab, we will give Owners at least 60 days’ notice by email and, if you ask during that time, give you a full copy of each Business’s records.

What happens to your data

Before an Account or Business is closed, export the reports and documents you need - after closing, we may not be able to give them back. We may keep some information where the law requires it, to resolve disputes or enforce these Terms, and copies of our databases on our servers may keep deleted information for some time; our Privacy Policy explains what we keep and for how long. Sections of these Terms that by their nature should survive - such as data ownership, amounts owed, disclaimers, liability limits, indemnity and governing law - continue to apply after termination.

Disclaimers

To the maximum extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy or non-infringement.

In particular, we do not warrant that costings, landed-cost and customs estimates, VAT figures, reports or ledger postings are correct or complete for your circumstances; that stock, expiry, reorder or dipstick figures match what is physically in your shop or tanks; that offline sales will sync; that a custom domain will connect or stay connected; that texts or emails will be delivered; or that defects will be fixed. Alerts and checks are aids, not guarantees. You are responsible for reviewing your own records and for the decisions you make based on them.

Limitation of liability

To the maximum extent permitted by law, Ado Systems and its people and suppliers will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, goodwill, data or business, arising out of or related to your use of (or inability to use) the Service - even if we have been told such damages were possible. We are also not liable for money you send to an account that Hisab does not list, or for transactions between you and your customers or shoppers.

To the maximum extent permitted by law, our total liability for all claims relating to the Service in any twelve-month period will not exceed the greater of (a) the fees you actually paid us for the Service in that period, or (b) ETB 5,000. Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited.

Indemnification

You agree to indemnify and hold harmless Ado Systems and its people from any claims, damages, losses and reasonable expenses (including legal fees) arising out of your Business Data; the content you publish on your storefront, website or domain; your sales to customers and shoppers; the messages and links you send; a domain you attach; your staff’s use of the Service; or your breach of these Terms, of any law or of anyone else’s rights.

Governing law & disputes

These Terms are governed by the laws of the Federal Democratic Republic of Ethiopia, without regard to conflict-of-laws rules. We both agree to first try in good faith to resolve any dispute informally by contacting each other. If we cannot, the competent courts of Addis Ababa will have jurisdiction, except that either party may seek urgent injunctive relief where necessary to protect its rights.

Changes to the Terms

We may update these Terms from time to time - for example, to reflect new features, legal requirements or changes in how we operate. When we make a material change, we will update the “Last updated” date above and email the address on each Owner’s Account. A change that is materially worse for you takes effect no sooner than 30 days after that email, unless the law or a security need requires it sooner; other changes take effect when posted, and price changes follow Plans, pricing & payment. If you keep using the Service after a change, you accept the updated Terms; if you don’t agree, stop using the Service.

General terms

• Entire agreement. These Terms and the documents they refer to are the whole agreement between us about the Service and replace any earlier agreements on that subject.
• No waiver. If we don’t enforce a right immediately, that isn’t a waiver of it.
• Severability. If any provision is held unenforceable, the rest stays in force, and that provision is applied as closely as possible to its intent.
• Assignment. You may not transfer your rights under these Terms without our consent. We may assign them to an affiliate or in connection with a merger, acquisition or sale of assets.
• Force majeure. Neither party is liable for delays or failures caused by events beyond its reasonable control.
• Language. These Terms are written in English. If we provide a translation, the English version prevails to the extent the law allows.
• No third-party rights. Only you and we have rights under these Terms; your customers, shoppers and others who receive your invoices, links or receipts do not.
• Electronic communications. You agree that we may give you notices, and that you may accept these Terms, electronically, and that electronic records of them count as written ones to the extent the law allows.
• Relationship. You and we are independent parties. Nothing in these Terms makes either of us the other’s partner, agent or employee.
