Keep your cash book without a spreadsheet.
Write down what comes in and what goes out. See your balance, your month, and your receipts — in one place, for free.
What you get
Money in, money out
One line per movement: date, description, category, amount. The running balance is calculated for you.
Your month at a glance
Totals per month and per category, so you can see where the money actually went.
Receipts attached
Upload the invoice or receipt for an entry and download it again whenever you need it.
Export what you need
A month as CSV for your spreadsheet, or as PDF for your folder or your tax adviser.
What you should know before you sign up
Your data lives on our server
Not in your browser. We store it so you can reach it from any device — which also means you are trusting us with it. Only you can see your own book.
Your recovery code is the only way back in
There is no email in this system, so we cannot send you a reset link. You get a recovery code once, at sign-up. Write it down. If you lose both your password and your code, the account cannot be recovered.
This is not a substitute for a Steuerberater
It is a tidy record of your cash movements, not certified bookkeeping, not a GoBD-compliant cash register, and not tax advice. For your annual accounts, talk to a tax adviser.
Free, and free of surprises
No card, no trial that ends, no reading of your receipts by any AI. Uploaded files are stored and handed back — nothing else is done with them.
