Why free?

Some tools include a link to Dutch bookkeeping software. If you sign up there, we receive a referral fee. That keeps every tool free. The tools work fully without it — you never have to click anything.

Frequently asked questions

Is this really completely free?

Yes. No trial, no premium tier, no account. Every tool is fully free to use, as often as you like.

What happens to my data?

Nothing. Everything you enter stays in your browser. There is no database and nothing is sent to a server. Close the tab and it's gone — unless you choose 'save my details', which stores them on your own device only.

Do I need to create an account?

No. No account, no email address, no newsletter. Open a tool and get to work.

How do you make money?

Some tools contain a single link to bookkeeping software. If you sign up there, that company pays us a referral fee — you pay nothing extra. That's what keeps the tools free.
