Not live in your country?Client book too big to self-serve?
We took Slovenia from a single inbound email to a fully working tax engine, entity types and compliance calendar in under 24 hours. Whether you're a founder in a country we don't support yet, or a practice with a client book that needs a tailored migration, tell us the shape of the problem and we'll build the fix, not point you at a generic signup form.
Two reasons people write in
Both get the same answer: tell us the specifics, and we'll build around them.
Founders in an unsupported country
Tell us your country and we'll research the real tax authority, company registry, VAT/GST rules, entity types and filing deadlines from official sources, then build a working tax engine and compliance calendar for it. Slovenia went from a cold inbound email to fully live in under 24 hours.
Practices with a large or unusual client book
500+ clients, a mix of countries, an incumbent you're locked into, or a service model that doesn't fit a self-serve signup flow — tell us the shape of your book and we'll design the migration, pricing and onboarding around it, not the other way round.
One inbound email. Live the same day.
A Slovenian accounting practice emailed us asking for local support. We researched FURS and AJPES from official government sources, built the corporate tax, VAT, payroll and entity-type rules, wrote Finn's country-specific knowledge, seeded the compliance calendar, and shipped it to production, live-verified, in under 24 hours. That is the speed we're offering you.
Why Xero won't do this
It isn't reluctance, it's structural. A 15-year-old platform serving millions of customers has no commercial reason to build for one practice or one small market. We do, because building fast is what an AI-native company is for.
| Xero (and incumbents generally) | AccountsOS |
|---|---|
Adds a handful of new countries across its entire history | Builds a new country's tax engine, entity types and compliance calendar in days, sometimes hours |
One-size-fits-all self-serve signup | Tailored migration plan, pricing and onboarding for practices with unusual or very large client books |
No incentive to serve a market too small for a public company | AI-native build process makes small and niche markets commercially viable for us |
Real government sources, every time
Every country rollout is researched from official tax authority and company registry sources, cited, and reviewed before it goes live. Speed doesn't mean guessing at tax rates. Finn always cites its source when it quotes a figure.
Tell us what you need
A country we don't support, or a client book that needs a tailored plan — either way, we'll come back with a real answer, not a form letter.
