The honest comparison
What typical software still bills extra for.
Xero, QuickBooks and Sage still split payroll, tax tools and the rest onto add-ons. Finn does the production work on one plan, and tells you when you genuinely need a human.

Still unsure? finn@accounts-os.com, we read every message.
- How does the free trial work?
- You get 14 days of full access to every feature, no credit card required to start. When the trial ends, keep going by adding a card ($24/month for a limited company, $12/month for a sole trader), or do nothing and your account simply pauses. No surprise charges.
- What does it cost after the trial?
- One plan, priced by entity: $24/month for a limited company, $12/month for a sole trader. A group of companies pays $24/month per company or ledger, on one bill. Everything included. No feature tiers, no add-ons. Cancel anytime.
- Is AccountsOS tax deductible?
- Business software subscriptions are commonly tax deductible, but local rules vary. At about $288/year for a limited company or $144/year for a sole trader (USD), keep the invoice and check the treatment with a qualified local professional.
- Can I cancel anytime?
- Absolutely. No contracts, no cancellation fees. Cancel with one click from your settings. Your data remains accessible for 30 days after cancellation.
- Will the price increase?
- The rate you sign up at is the rate you pay, we don't do annual price hikes. $24/month for a limited company, $12/month for a sole trader, flat.
- Are there any hidden fees?
- None. Everything is included: payroll, dividends, invoicing, all calculators, unlimited AI chat, and bank import. No per-feature pricing.
- Do I still need an accountant?
- Finn does the recurring production work: bookkeeping, tax estimates, deadlines, payroll, dividends, invoicing. Keep a qualified accountant for audits, investigations, company sales and unusual tax. If you already have one, they can work from live books instead of a year-end dump. Plenty of practices run Finn as a colleague on their team.
- Is my data secure?
- Yes. We use bank-level encryption and store data in the EU (Helsinki, Finland), GDPR compliant. Your data is never used to train AI models and is never shared with third parties.
- Can I use this for multiple companies?
- Yes. Each company is its own workspace with its own ledger. Put them in a group and you get one bill at $24/month per company, plus a group view of the P&L and reports across every entity, in any country, with the option to dip into each one.
- What about accountancy practices and larger companies?
- Practices pay per live client on the practice plan, billed in arrears, with the full price list on the for-accountants pricing page. Enterprise, a bigger and deeper-thinking Finn for large corporate accounts, is coming soon. Email finn@accounts-os.com to talk about it.
