Udhaar Khata App: Keep Track of Credit Customers and Suppliers

Add customers and suppliers

1. Open the Khata tab.
2. Add a customer or supplier with name and mobile number. Address, state and GSTIN are optional.
3. Optionally set credit days (when payment is due) and a credit limit for the customer.

Record an udhaar sale

1. Make the bill in Sales → New Sale and pick the customer.
2. Choose Credit (udhaar) as the payment mode, or enter a partial paid amount.
3. The unpaid amount is added to the customer's khata balance automatically. If the customer has a credit limit, the app warns you when a bill would cross it.

Receive a payment

1. Open the customer in Khata and tap Receive Payment (or use Payment in).
2. Enter the amount and mode — UPI, cash, bank or card — and save.
3. The balance updates, and you can share a payment receipt PDF on WhatsApp.

Remind customers on WhatsApp

• From the customer screen, send a WhatsApp payment reminder with the outstanding balance and your UPI payment link — no SMS charges.
• Share a party statement PDF for any date range, with opening and closing balance.
• The Outstanding & ageing report groups dues into 0–30, 31–60, 61–90 and 90+ days so you know whom to call first.
• On a paid plan the Android app can also schedule reminder notifications around the due date; nothing is sent to the customer until you tap.

Supplier khata (payables)

Purchase bills on credit go into the supplier's khata the same way. Record payment out when you pay the supplier, and share the supplier statement if you need to match accounts.

Your data

The khata works offline on your phone. When you sign in with Google, it syncs to your BizBahi account so you can open the same khata in the web app at bizbahi.com/app or on a new phone. You can set a PIN lock so nobody else opens it.

Does the udhaar khata work offline?

Yes. Khata, billing and payments work offline on the phone, and sync to your account when you are back online.

Can I send udhaar reminders on WhatsApp?

Yes. From a customer with a balance you can send a WhatsApp reminder with the outstanding amount and your UPI payment link. There are no SMS charges.

Can I set a credit limit for a customer?

Yes. Set a credit limit and credit days on the customer. The app warns you when a new bill would cross the limit.

Can I keep supplier udhaar too?

Yes. Supplier purchases on credit and payments out are tracked in the supplier khata, with a statement PDF you can share.
