Made to be exact

Add it up as you type.

A khata is only as good as its numbers. SureBook checks them with you before you save, and keeps every change after.

  • A calculator on the padType 450 + 230 and save ₹680. Paise work too, like ₹250.50.
  • The amount in words"छह सौ अस्सी रुपये" under the number, so a slip shows before you save.
  • The balance afterBefore you save, see what the customer will owe once this entry is in.
  • A check for double entriesSaved the same amount for the same person twice in two minutes? A note says so, with Undo.

Questions

The short answers.

Anything else, write to us at contact@vempus.com.

Is SureBook free?

Yes. There are no ads, no subscription and no hidden charges.

Where is my data kept?

Only on your phone. Android can back it up to your own Google account, and you can save a backup file any time from Settings.

What if I change my phone?

Save a backup file in Settings and open it on the new phone, or let Android's own backup bring it across.

Does it need the internet?

No. Only WhatsApp, SMS and the customer's UPI app need a connection when you use them.

Does SureBook take payments?

No. Customers pay your UPI ID from their own UPI app, and the money goes straight to your bank. SureBook never holds, moves or sees it.

Can I bring my customers from another app?

Yes. Save your customer list as an Excel (CSV) file with names, phone numbers and balances, then open it from Settings. You see what will be added first, and one Undo takes it all back.

What is the cashbook?

Your galla: sales, expenses and other money in or out, day by day. Payments you write in the khata as Cash, UPI or Cheque show up there by themselves.

Why the two lines

The total, ruled twice.

In an old ledger, the munim draws two lines under a total once it is checked and final. Those two lines say "pakka": settled, no more changes. SureBook brings that to your phone.
