How it works
Throw it at Finn.Get back a set of books.
Finn isn’t software you learn, it’s an accountant that works in the background. Snap, forward, dictate or sync. Finn processes it, flags what’s wrong, and prepares your Form 1120 / 1120-S / 1040 Schedule C for approval.
The loop
Four steps, then it repeats.
This is the whole product. Everything else is a detail of one of these four steps.
You hand it over
Snap a receipt, forward an email, ask a question, or let the bank feed run. No forms, no fields.
Finn does the books
Extracts the data, categorises against your country's chart of accounts, matches it to an invoice, updates the ledger.
Problems get flagged
Personal spend on the business card. A missing receipt. An amount that doesn't fit the pattern. Finn spots it and says so.
Finn walks you through it
Ask Finn on any flagged item and it explains the options, director's loan, reimbursement, whatever fits, then does it once you pick.
You don’t “use” Finn. It runs in the background on everything you send, and comes to you when a decision is actually needed.
Step one, in detail
Four ways to brief Finn.
Whichever you use, the same processing runs behind it.
Snap receipts
Photograph any receipt. Finn reads vendor, amount, date, VAT and category, even crumpled and faded.
- Auto-categorised by expense type
- Original image kept for tax-authority compliance
- De-duped if the same receipt arrives twice
Forward emails
Send invoices, statements and receipts to your company's address. Finn classifies each one and acts.
- A unique address per company
- PDFs, images and plain text all handled
- A proposal email can open a whole deal
Talk to it
Ask questions or log expenses hands-free while you drive. Real-time and interruptible, in 100+ languages.
- Any accent, no training needed
- Finn acts on it, not just a transcript
- Complex questions answered out loud
Upload in bulk
Drop a month of paperwork or a year of statements in one drag. Finn works through it in the background.
- PDF, CSV and Excel supported
- Bank statement format auto-detected
- Retry-safe, so nothing is silently dropped
Or don’t come to Finn at all. WhatsApp, Slack, Telegram, Claude and the CLI all reach the same accountant.
See every connectionStep two, in detail
The right model for the question.
Finn isn’t one model behind a chat box. Simple lookups go somewhere fast, reasoning goes somewhere capable, and receipts go to vision. You never pick, and it improves without you migrating.
How routing worksRouting is automatic. Model choices change as better ones ship.
- Is Finn a replacement for an accountant?
- For most small companies, UK Ltd, Irish DAC/CLG, Bulgarian OOD/EOOD, UAE FZCO/FZE/LLC, Australian Pty Ltd, US LLC/S-corp/C-corp, HK Ltd, Turkish A.Ş. / Ltd. Şti., Isle of Man Ltd, yes. Finn handles bookkeeping, tax calculations, and filing preparation. For complex situations (audits, large transactions, cross-border restructuring), you might still want professional advice, but Finn reduces that need significantly.
- How secure is my financial data?
- We use bank-level encryption, store data in a UK data centre in London, and never share your information with third parties. Your data is never used to train AI models.
- Do I need to be tech-savvy to use this?
- Not at all. If you can take a photo or forward an email, you can work with Finn. The whole point is that you don't need to learn accounting software, just talk to Finn like you'd talk to an accountant.
- What happens if I have questions Finn can't answer?
- Finn is trained on the tax law and authority guidelines of every country it's live in. For edge cases, it'll tell you honestly and suggest consulting a local professional. We'd rather say 'I don't know' than give bad advice.
