About OpenAccountants

We help business owners get their accounting and tax work done.

OpenAccountants is an accounting firm that works with AI, with accountants in different countries. Tell us about your business and we'll confirm whether we can help, who will be responsible for the work and what it will cost. We also publish free, source-cited Guides that people and AI tools can use.

What OpenAccountants does

Bookkeeping and tax work, handled

Bring us the work you need, the countries involved and any deadline. We confirm the scope with the right accountant and give you a written quote before work starts. Explore our accounting services →

Free Guides for the AI you already use

Add OpenAccountants to ChatGPT, Claude, Gemini or Cursor and it reads a Guide before answering, with the sources it used. There are 1,893 Guides, free to use.

An open library accountants build

Accountants write Guides and check each other's, and their name stays on the work. The whole library is public on GitHub.

What makes OpenAccountants different

It works inside the AI you already use

No new app. Add it once to ChatGPT, Claude, Gemini or Cursor and your AI reads a Guide before it answers a tax question.

Sources, not confidence

Every Guide shows the official sources it relies on and its version history, so you can check the method behind an answer.

Named people on the work

When an accountant writes or checks a Guide, their name is on it, and it stays on it.

We say what has not been checked

Of 1,893 Guides, 258 carry a named accountant. The rest are labelled as built by Michael Cutajar and the OpenAccountants team, because they are.

Open, and free

The whole library is public on GitHub. Anyone can read it, use it or suggest a fix.

Who uses OpenAccountants

  • Business owners who want help getting bookkeeping and tax work done
  • Freelancers and businesses dealing with more than one country
  • People who ask ChatGPT, Claude or Gemini tax questions and want sources behind the answer

Frequently asked questions

Are the Guides free?

Yes. Anyone can read them on the site, add them to ChatGPT, Claude, Gemini or Cursor, or download them from GitHub.

Is a Guide advice on my situation?

No. A Guide is general reference material with its sources. For your own situation, talk to a qualified professional.

How do I know whether a Guide has been checked by an accountant?

Every Guide shows its label. Most are built by Michael Cutajar and the OpenAccountants team from official sources, and say so. The others name the accountant who wrote or attested to them.

Are the accountants on the site part of OpenAccountants?

The accountants credited on Guides are the professionals who wrote or checked that material. Client work is a separate engagement with OpenAccountants: your written quote names the accountant responsible for your work.

Yes. Book a free 30-minute call with our team, or email info@openaccountants.com.
