Quick answer: Yes, AI bookkeeping can make mistakes, most commonly miscategorising an unusual or ambiguous transaction, the same category of error a person doing manual bookkeeping is prone to. The difference is that a well-designed AI system flags low-confidence categorisations for your review rather than silently guessing, and it improves the more transaction history it sees.
It’s a fair question, and one worth asking before you trust any software with numbers that go to HMRC: if an AI is categorising your transactions, can it get things wrong? Yes. The more useful question is how, and what a good system does about it.
Where AI categorisation errors actually come from
Most errors happen with ambiguous transactions: a payment to a company that sells both business and personal goods, a one-off transaction unlike anything in your history, or a transfer between your own accounts that could plausibly be either. These are the same transactions that trip up manual bookkeeping too; AI doesn’t introduce a new category of mistake so much as it processes far more transactions than a person reasonably reviews line-by-line.
What good AI bookkeeping does differently
A well-built system flags transactions it’s less confident about for your review, rather than silently categorising everything with equal certainty. It should also improve over time as it learns your specific patterns, a coffee shop near your office that’s sometimes a client meeting and sometimes personal, for example, becomes more reliably categorised the more history it has to draw on.
What to check before submitting
- Review any transaction flagged as low-confidence or uncategorised before every quarterly submission, don’t rely on it being caught automatically.
- Spot-check a handful of larger or unusual transactions each quarter, even ones the software categorised confidently.
- Check your bank feed coverage is complete; an AI can only categorise transactions it can actually see. See is it safe to connect your bank to AI bookkeeping for how that connection works.
- Remember quarterly updates are cumulative, so if you do catch an error after submitting, it’s corrected in the next quarter rather than requiring a formal amendment. See how to correct an MTD quarterly update.
