Everything you used to write in a register — and a lot more.
A ledger for every customer

Item lists
Add items with quantity and rate to a credit entry and the total is calculated for you. Set a due date too.
Overdue & ageing
See instantly whose payment has been pending for 30, 60 or 90 days, with a warning when a customer goes over their limit.
Reports & export
Today, week, month, financial year or a custom range. Collections by payment mode, CSV export and shareable statements.

Frequently asked questions
Is Credit Book free?
Yes, it is completely free. No ads and no hidden charges.
Does it work without internet?
Yes. Every entry is saved on your phone. If you are logged in, it is backed up to the cloud automatically as soon as you are online.
Do I have to log in?
No. You can use the app without logging in, but then your data stays only on that phone. Logging in means you get your ledger back if you change phones.
Who can see my data?
Only you. Your backup is tied to your account, and security rules stop any other user from reading it.
How do I send a reminder to a customer?
Tap the WhatsApp or SMS button on the Collections page or in the customer's ledger. The message is ready with the balance due — just tap Send.
How do I delete my account and data?
In the app, go to Settings → "Delete account and cloud backup". This permanently deletes your login and your cloud backup. More details.
