Udaar Book App: How to Choose the Best Digital Udaar Book

Every shop that gives credit keeps an udaar book. Moving it to your phone takes an afternoon, but choosing the wrong app can cost you months of records. Here is what to look for.

Quick answer

An udaar book (also written udhaar book or udhar khata) is the register where a shop records goods given on credit and the payments received, one account per customer. An udaar book app keeps the same record on your phone: it adds up every balance, backs up your records and sends customers their statement on WhatsApp. When choosing one, check that it is free to use in full, works in your language, works offline and backs up your data. MobiKhata does all of that for free on Android, iPhone and the web.

Key takeaways

  • An udaar book app is a digital credit register: one account per customer, each with a running balance.
  • The four checks that matter most: free in full, your language, works offline, backed up.
  • You can move a paper udaar book in one sitting by entering each customer’s current balance as an opening entry.
  • Share a statement before you ask for payment; most disputes end there.

What is an udaar book?

Udaar (ادھار), also spelled udhaar or udhar, is credit: goods given now and paid for later. The udaar book is where a shopkeeper writes it down. In most shops it is a long register or a red bahi with a page for each regular customer. Every line records a date, what was taken, the amount and any payment made, so the shopkeeper can tell at a glance who owes what.

The idea has not changed in generations. What has changed is how many customers a shop serves on credit, and what a mistake costs. A lost page or a wrongly added total is money that is hard to get back, and often an argument with a good customer. For the meaning of udaar and how it works between shop and customer, see what is udaar; for the columns of a paper register, see our khata book format guide.

A paper register still works for a shop with a handful of credit customers. Once you have dozens, the time spent adding up and the risk of a lost page make an app worth the switch.

What to look for in an udaar book app

  1. Free to use in full. Some apps are free to download but charge later. Check the “Contains ads” and “In-app purchases” labels on the store page; our guide to which khata apps are really free explains what to look for.
  2. Backup and sync. Sign in with Google, Apple or email, so a new phone restores every customer and balance.
  3. Works without internet. Entries should save on the phone during a power or signal cut and sync later.
  4. Your language. If you or your staff read Urdu, Pashto or Dari more easily than English, the app should be in that language.
  5. Customers and suppliers. Udaar goes both ways. You need to see what you will receive and what you have to pay.
  6. Statements on WhatsApp. A PDF statement with dates and a running balance is the most polite way to ask for payment.
  7. Reminders. Scheduled balance reminders save you from remembering every due date yourself.
  8. Lock and privacy. A fingerprint or Face ID lock keeps customers’ balances private, and the app should have no ads and not sell your data.
  9. Your currency. If you deal in more than one currency, each should have its own balance. MobiKhata keeps one currency per business, so you can run a rupee business and a dollar business side by side.

How to move your paper udaar book to MobiKhata

  1. Download MobiKhata free from Google Play or the App Store and sign in with Google, Apple or email.
  2. Choose your language in Settings and create your business with its currency, for example Pakistani rupee (PKR).
  3. Add each customer from your register as a party, with a phone number so you can send statements.
  4. Enter the current balance as one Cash Out entry with the note “Opening balance from register”. Entries can be backdated, so use the date of the last line in the register.
  5. Do the same for suppliers, entering what you owe them as a Cash In entry.
  6. From today, record at the counter. Goods given on udaar are a Cash Out; a payment received is a Cash In.
  7. Keep the paper register for a month as a backup, then retire it.

Start with the ten customers who owe the most; the rest can follow over a few evenings. For example, if the register shows that Rashid owes Rs. 12,400 as of 1 November, add Rashid as a party and record a Cash Out of Rs. 12,400 dated 1 November with the opening-balance note. His balance appears under To Receive straight away.

Using your udaar book well

  • Agree a payment day when you give udaar, and put it in the entry note: “1 tareekh tak”.
  • Decide a limit for each customer from their payment history, and pause new udaar when a balance passes it.
  • Look at To Receive once a week and send statements to the customers who owe the most.
  • Send the statement before you ask. A customer who sees their own dated entries rarely argues. Our payment reminder templates help with the wording, and udhar wapas kaise le covers what to do when payments stop.
