Frequently Asked Questions
How does affordable bookkeeping work with AI?
You upload receipts, forward emails, or import bank statements. Finn reads the documents, extracts supplier names, amounts, dates, and VAT, then categorises everything correctly. You review and approve. That's it.
Is cheap bookkeeping software reliable?
AccountsOS uses the same AI models that power leading products from Google and Anthropic. It's more accurate than manual entry and never gets tired. Every categorisation includes a confidence score so you know exactly how certain Finn is.
What if the AI makes a mistake?
You're always in control. Finn suggests categories but you can change them with one click. Over time, it learns your preferences. For complex transactions, you can chat with Finn to understand its reasoning.
Can affordable bookkeeping handle VAT?
Yes. AccountsOS calculates your VAT automatically, generates the 9-box return, and submits directly to HMRC via Making Tax Digital. No extra fees, no separate software needed. All included in the £20/month.
