How OpenAccountants works
Tell us what you need. We help get it done.
Bring us your bookkeeping or tax work, the countries involved and any deadline. We confirm whether we can help, the accountant responsible and the price before you commit. You can also use our free Guides to research your own questions.
Getting your accounting work done
1. Tell us what you need
Book a free 30-minute call. Tell us about your business, the countries involved and the work you want to hand over.
2. Agree the scope and price
We confirm the accountant, the work included, the timing and the price in a written quote.
3. Hand over the work
After you accept, we arrange the handover and your accountant gets started. You know who to contact.
How our free Guides work
Read the Guides here or add them to ChatGPT, Claude, Gemini or Cursor. Each Guide shows its sources and review status. Using the library does not create a paid engagement.
You add it to your AI, once
OpenAccountants is a free plugin for ChatGPT, Claude, Gemini and Cursor. Adding it takes about two minutes; from then on your AI reads the Guide for your country and your problem before answering, and it shows the official sources the Guide cites.
Missing Guides get drafted overnight
When someone asks a question we have no Guide for, our engine writes one that night, reading only official government pages. It may not publish a number without a link, and if it cannot find the figures officially, it refuses to write. Every engine draft is labelled “Drafted by Michael Cutajar and the OpenAccountants team, awaiting an accountant's approval.”
An accountant puts their name on it
A licensed professional reads the Guide, corrects it, and takes the byline. From then on their name travels with every answer an AI gives from it: on the site, in your AI, and on GitHub.
Nobody's name moves without their say
Suggest a change to a reviewed Guide, from the site or on GitHub, and that accountant sees it first and approves or rejects it with one click. Unreviewed Guides are always labelled as built by Michael Cutajar and the OpenAccountants team, never dressed up as reviewed.
A question with no Guide → drafted overnight from official sources → an accountant takes the byline → your AI answers better
Checked every night, while you sleep
A tax library is only as good as its worst stale number. So machines re-check ours nightly, and what they find is fixed at the source, not papered over.
The maths check
A checker re-reads every Guide, every night, and flags sums that do not add up, tax bands with gaps, totals that do not total, and years that disagree.
The source watch
Where a Guide links an official page, a watcher visits that page and raises a hand when it changes, so a law change never goes quietly.
The refresh engine
The stalest Guides get re-derived from the official sources on a fixed monthly budget the engine cannot exceed. Reviewed Guides go back to their accountant for approval; drafts update themselves.
The nightly exam
We test whether AIs actually said what our Guides say that day, or improvised. Improvisation gets caught, counted, and fixed at the source.
Open, so you can check us
The whole library lives in the open on GitHub. Anyone can read it, and anyone can fix it: merged fixes flow back into what every AI serves, credited to the person who made them, by name, in the public record. When an accountant improves a Guide here, the change lands on GitHub under their own name too. The division of labour is simple: machines do the drafting, the checking and the watching, because they never get bored. Accountants do the one thing machines cannot, which is put their name on it.
Access methods
Our free Guides and automated outputs are general reference material, not advice on your situation. Professional work requires a separate engagement with an accountant. Have outputs reviewed before filing, payment or action.
