Kletta as a company
By entrepreneurs, for entrepreneurs
Bookkeeping has to be in order, but it doesn’t have to be complicated. That’s why we made Kletta: a Finnish accounting app built only for sole traders.

Kletta has made my bookkeeping and customer invoicing so much easier since I switched to it — the app is very clear and easy to use!
Not-so-frequently asked questions
Was it hard to make Kletta easy to use?
Yes and no. We had one goal: bookkeeping should work with one tap. It sounded easy until we realised how much bookkeeping actually involves. But we didn’t give up – we just automated everything we could. Now it’s easy for you, because it was hard for us.
Why do you focus only on sole traders?
Because we want to do one thing perfectly. Sole traders are often overshadowed by bigger systems, even though they do a big job. We wanted to change that. And we know these people – some of us have been there ourselves.
Who is David Kletta?
He’s our AI chat – a bit like an accountant, but always awake and never on a coffee break. David may not be much for small talk, but tax questions are another matter: he answers them like an accountant. The idea for the name came from our chair of the board.
What’s your motivation – why are you doing this?
Because we’re tired of sole traders’ lives being needlessly hard. We don’t want anyone’s business to collapse under a mountain of receipts or tax panic. Our goal is for you to focus on your work – Kletta takes care of the rest.
Can Kletta make the coffee too?
Not yet, but it saves so much time that you can make it yourself – calmly, and in the right cup. And if we ever get a coffee machine integration, it will definitely be a Kletta Care feature.
