What is still missing for my annual financial statement in mika?
Loaded tools, used mika MCP

mika only needs the loan agreement for your shareholder loan (Gesellschafterdarlehen), everything else is almost done.

I found a signed loan agreement from January in your Google Drive. I am fairly confident it is the right one: the loan amount matches the incoming payment on your business account. Want me to upload it for you?

The human factor

The AI handles the volume. People decide when it counts

You get both: the speed of AI and the reassurance of trained accountants. When something is unclear, a person answers.

  • Whatever the AI is not sure about goes to an accountant. Not into your inbox
  • Answers that are quick and on eye level, without jargon
  • Questions from the Finanzamt? Forward them, and we handle it together with you
  • For tax structuring we connect you with partner tax advisors

What founders ask us most

mika is a Berlin startup that has built AI-based bookkeeping software for founders. mika takes over your day-to-day bookkeeping, prepares your VAT return and annual financial statement, and helps you understand letters from the authorities. So you can take care of your business, not your paperwork.

Up to 80 % less time on bookkeeping and around 60 % lower costs than with a tax advisor. On top of that, mika warns you proactively about missing receipts and deadlines before anything slips.

With other programs you do the books yourself. mika recognises receipts automatically, reconciles them with your bank and posts them, checked by trained accountants. And the annual financial statement is already included, instead of you needing a tax advisor for it after all.

If you are perfectly happy, you do not need mika. Many people, though, outsource their day-to-day bookkeeping to mika and keep their tax advisor only for structuring questions. Or replace them entirely.

Yes, any time. Your current firm sends us a DATEV export, and mika takes over the data including past months. Switching usually takes two to three weeks.

mika is built for German GmbHs, UGs and AGs, typically up to 50 employees and without an in-house finance department. For freelancers, GbRs and sole proprietors mika is not available yet.

No. mika works with many tax advisors. If you like, we join a call and clear everything up directly. Through the DATEV export your firm always gets clean data.

Yes. mika assigns accounts automatically under SKR03 or SKR04, including tax keys. Trained accountants review the results.

Yes, on request. We recommend a short call first so we can set mika up to fit your business right away. mika delivers its full value when it takes over your entire bookkeeping.
