Transparent Pricing for Practices
No per-user fees. No feature gates. One price based on the live clients you actually manage.
Practices should not have to guess what the bill will be. AccountsOS charges for live client companies, applies volume discounts automatically, and lets archived clients stay available read-only without affecting billing.

Practice Mode: common questions
Can I move my whole client book to AccountsOS?
Yes. Practice Mode includes bulk client-book migration: you add each client and paste their export from Xero, QuickBooks or Sage, AccountsOS creates a company per client, and Finn works out what each file is (trial balance, contacts, open invoices and bills, opening balances, VAT history). You see exactly what it will import and review before anything posts to the books.
How much does AccountsOS cost for an accounting practice?
Practice pricing is based on live client companies, with a £299/month minimum and automatic volume discounts as your book grows. You pay, not your clients, archived clients stay available read-only without counting as live, and the price does not climb every September the way Xero and QuickBooks have.
Do my clients need to log in or pay anything?
No. Clients are covered by your practice plan, not billed their own subscription, and they never need to log in. You are the user, Finn is your tool, and the Practice Dashboard is your command centre.
How is this different from Xero or QuickBooks for accountants?
Xero and QuickBooks charge per client and have raised UK prices repeatedly while unbundling features into paid add-ons. AccountsOS gives the practice AI-native migration, Finn across the whole client book, API access and MCP access in one platform. Finn does the categorisation, reconciliation and month-end across your whole book, so each person on your team services more clients instead of more software.
Can AccountsOS file VAT to HMRC?
Yes. AccountsOS is HMRC-recognised software for MTD VAT and files VAT returns straight to HMRC. MTD for Income Tax support is coming for the April 2026 changes.
How does Finn save my practice time?
Finn reads receipts, statements and invoices, categorises them, reconciles the bank, and prepares month-end and year-end across every client in the background. Your team reviews the exceptions rather than doing every line, which is how one person services far more clients.
Which countries does AccountsOS support?
AccountsOS is live in 21 countries, including the UK, Ireland, the US, UAE, Australia and most of Europe, each with country-specific tax rules, deadlines and compliance. You can manage clients across multiple countries from one practice account.
Is there a contract or lock-in?
No long-term lock-in. Practice pricing is straightforward and your data is yours. You can export at any time.
