AI bookkeeping software

AI bookkeeping software uses artificial intelligence to do the part of bookkeeping that used to be typing: reading a receipt, a supplier invoice or a bank statement, working out what it is, and proposing the accounting entry. The owner or bookkeeper then approves the proposal instead of creating the entry from scratch. It does not replace knowing your business, and it does not move responsibility for the figures away from you. This page explains what the technology does well, where it needs a person, and how to judge a product. Nexbal, the example used here, is an AI accounting platform launching in the UK as a beta.

What the AI actually does

The difference from older automation is where the knowledge sits. Rules-based software does what you told it: “payments to this supplier go to motor expenses”. Someone has to write and maintain those rules, and they fail on anything new. AI-based software reads the document itself, so it can make a sensible proposal for a supplier it has never seen, on a receipt format nobody set up.

A week with and without it

A design studio with two directors receives about forty supplier documents and one busy bank statement a month.

The saving is not that the work disappears. It is that your time moves from data entry to review, which is the part that needs you.

Where a person still has to decide

No reader of documents, human or machine, can know what is not on the page. Expect to make the call on:

• Business or private. A supermarket receipt may be office supplies or the weekly shop.
• Capital or expense. A laptop is not treated like printer paper; see capitalisation policy for fixed assets.
• VAT treatment. Whether VAT can be reclaimed depends on your registration, the scheme you use and the purpose of the purchase, not only on what the receipt shows.
• Which period it belongs to. An annual subscription paid in March covers months in the next year; see cut-off at month end.
• Unusual items. Loans, director’s money in and out, grants, insurance claims and refunds.

A well-designed product is honest about this. It posts what it is sure of, shows you what it is unsure of, and never hides the difference. In Nexbal, entries from receipts wait for your approval, and bank statement lines the AI cannot match are listed for review rather than guessed.

You remain responsible for the figures

Using software, or an accountant, does not transfer your legal duties:

• You must keep records that support your return, whether you are self-employed or a limited company.
• HMRC can charge a penalty for an inaccurate return where the error results from a failure to take reasonable care; its factsheet on penalties for inaccuracies in returns or documents explains how behaviour affects the amount.

Reviewing AI proposals is how you take reasonable care in an AI-assisted workflow. That is why the approval step matters, and why the source document should stay attached to every entry: when a figure is questioned, you can show what it was based on. Our guide to manual journal approval and audit trail covers the wider controls.

Tax returns are a separate step. The VAT return or Income Tax updates go to HMRC through MTD-compatible software or your accountant, using the figures from the books; the AI’s job is to make those books complete and current.

Your data

Bookkeeping documents contain personal data: names on invoices, staff expense claims, bank details. Before you upload a year of paperwork to any provider, read where the data is stored, who can access it and what the provider’s role is under UK data protection law. A serious supplier publishes this. Nexbal’s terms are in its data processing agreement and security overview.

How to test AI bookkeeping software

Claims are easy to make and easy to check. Use one real month:

1. Pick twenty documents on purpose: clean PDFs, a faded till receipt, a foreign currency invoice, a handwritten one, a multi-page bill.
2. Count the results. How many came out right in every field? How many needed one correction? How many failed?
3. Upload a real bank statement. Note how many lines were posted, how many were queued, and whether any posted line is wrong. Wrong postings matter more than queued ones.
4. Check the closing balance in the ledger against the statement.
5. Time the review. The honest measure is minutes spent per month compared with now.
6. Look at the trail. For any entry, can you see the document and what was approved?

What it costs

Products charge in different ways: a flat monthly plan, a price per user, or a price that rises with the number of documents. Work out the cost for your real volume, then set it against the hours of typing it replaces and what your accountant charges for year-end clean-up. Nexbal’s plans are listed on the pricing page, and the beta is free for 30 days.

AI bookkeeping in Nexbal

From the first day of the beta you can:

• Forward or upload receipts and supplier invoices and approve AI-prefilled entries
• Upload bank statement PDFs from any bank and review only the lines that were not matched
• Send quotes, invoices, credit notes and reminders by email, in sterling or foreign currencies
• Keep projects, timesheets, expenses, a driving log and an asset register alongside the ledger
• Read reports, including margin and liquidity, built from entries that each carry their document
