# What is a credit book? Digital credit book vs the paper register - URL: https://ck.abdohoo.app/blog/what-is-a-khata-book-digital-vs-paper-register - Product: Credit Khata (https://ck.abdohoo.app/) - Section: Explainers - Updated: 2026-10-15 > A credit book is a shop's credit register: who took goods on credit, and who has paid. A digital credit book keeps the same record but adds totals, backups, reminders and a customer view. A credit book is a shop's credit register. Each regular customer has a page, and every time they take goods on credit the shopkeeper writes the date, the items and the amount; every time they pay, the payment goes on the same page and the balance comes down. A digital credit book keeps exactly the same record in an app, but works out the totals, keeps a backup, sends reminders, and can let the customer see their own page. It is, quite simply, a book of customer accounts. Across Pakistan, India, Bangladesh and beyond, the kiryana store, the dairy, the pharmacy and the mobile repair counter all keep one, because selling on trust to regulars is how neighbourhood trade works. ## How a paper credit book works A typical register is a long notebook with a page, or a few lines, per customer: - the **date**, - **what was taken**, for example "atta 10 kg, cheeni 2 kg", - the **amount**, - and, whenever the shopkeeper has time, a **running total**. Payments are written in the same place, often with a line through the old total. Some customers keep their own small copy; most rely on memory and on the shopkeeper's word. At the end of the month, or on salary day, the shopkeeper adds up the page and tells the customer what they owe. It is cheap, it needs no electricity, and everyone understands it. That is why it has lasted. ## Where the paper register lets you down The trouble with paper is not the paper. It is what happens around it. 1. **Two versions of the truth.** The shop has the register; the customer has their memory. When the two disagree, there is nothing on the customer's side to check, and the conversation turns into an argument at the counter. 2. **Arithmetic by hand.** Running totals are added up in a hurry, between customers. One slip carries forward into every total after it. 3. **One copy.** A spilt cup of chai, a leaking roof or a lost notebook can wipe out months of credit, and there is no backup. 4. **No overview.** A register tells you what one customer owes when you open their page. It does not tell you who has owed for three months, or how much credit the whole shop is carrying. 5. **Nobody reminds anybody.** Collecting depends on the shopkeeper remembering to ask, and many feel awkward asking. 6. **Hard to share.** When a son, a brother or a salesman runs the counter, they either use the same book, with no record of who wrote what, or write on loose slips that get copied in later, or do not. 7. **Everyone can read it.** Any customer standing at the counter can see other people's pages. ## What a digital credit book changes A digital credit book keeps the familiar idea: one account per customer, credit in, payments out, a balance. What changes is everything around the record.

A shop counter is exactly where the signal drops, so a good digital credit book saves entries on the device first and uploads them later. We explain why in [Why an offline-first ledger matters for small shops](https://ck.abdohoo.app/blog/why-an-offline-first-ledger-matters-for-shops). ## The shared ledger: the customer sees the same page The biggest change is not the arithmetic; it is who can see the record. In a shared ledger, the customer opens the same account the shop writes, on their own phone. They see each entry, what it was for, and the balance, as soon as the shop records it. ![A customer's account in Credit Khata on a phone: the balance still owed, totals bought on credit and paid back, the shop's card with due date and credit limit, and each entry grouped by month](https://ck.abdohoo.app/storage/content/library/mobile-cust-home.webp)A shared ledger: the customer reads the same account the shop writesThat removes most disputes before they start. When a customer can point at one line and say "I took one packet, not two", the shop can check that line, correct it, and reply, and both sides keep the note. It also makes paying easier: the balance, the due date and the shop's payment details sit in the same place. This is how Credit Khata is built. The shop writes the entry at the counter; the customer opens their account from a link or a short code, in any phone browser, without installing anything, and it is always free for customers. How customers use it is described in [For customers: open your account, check entries and pay the shop](https://ck.abdohoo.app/help/customer-open-check-pay-your-khata). ## When paper is still fine Paper is not wrong. A shop with a handful of credit customers who all pay on time may never need more. And some shopkeepers keep a paper book as a habit alongside an app. If you do both, choose one as the record. Writing every entry twice is where the old problem of two versions of the truth comes back. Most shops that switch keep the old register as an archive and write new entries only in the app. ## What to look for in a digital credit book app - **Works offline**, so the counter never waits for the network. - **Customers can see their own account**, not just receive a message. - **Items and quantities** on each entry, not only amounts. - **Your language and script**, including right-to-left for Urdu. - **Opening balances**, so you can carry over what the paper book says. - **Staff logins with roles**, if anyone else works the counter. - **Exports**, so your data is never locked in. - **No cut of your payments.** Customers should pay you directly. ## How to start If you keep a register today, the move is mostly about one date and one set of opening balances. Our step-by-step guide covers it: [Moving from a paper credit register to an app, step by step](https://ck.abdohoo.app/blog/move-from-paper-khata-register-to-app).

It means goods or money given now, to be paid back later. In a shop it usually means a customer takes groceries now and pays at the end of the week or month. ### Is a digital credit book better than a paper register? For most shops with regular credit customers, yes: totals are always right, the record is backed up, and customers can see it. A very small book with a handful of customers can still work well on paper. ### Can my customers see their own account in a digital credit book? In a shared-ledger app like Credit Khata, yes. The customer opens the same account the shop writes, on their own phone, from a link or a code. ### Do I need the internet for a digital credit book? Not all the time. An offline-first app saves entries on the device and uploads them when the connection returns.
