Frequently Asked Questions
Is AccountsOS really cheaper than an accountant?
Yes. Traditional accountants charge £100-300/month for basic bookkeeping and year-end accounts. AccountsOS costs £20/month and includes everything: bookkeeping, VAT returns, receipt scanning, and unlimited AI support via Finn. That's a saving of up to £3,360/year. There's also a 14-day free trial so you can verify the value before you pay a penny.
Can a cheap accounting solution handle my limited company?
Absolutely. AccountsOS is specifically designed for UK limited companies. We handle VAT MTD submissions, Corporation Tax calculations, dividend tracking, director's loan accounts, and Companies House compliance, all the things your accountant would do.
What's the catch with cheap accounting software?
No catch. We're able to offer competitive pricing because AI does the heavy lifting. Unlike traditional accountants who charge for every hour, Finn works 24/7 at no extra cost. You get unlimited questions, unlimited receipt uploads, and all features included in the flat £20/month.
Will I still need an accountant for year-end?
For most small limited companies, no. AccountsOS prepares your accounts, calculates Corporation Tax with correct marginal relief, and helps you file. Some businesses with complex needs (multiple entities, audits, international operations) may still benefit from occasional accountant input.
