YES

As of 13 August 2026, AI can break down your expenses by category.

Most people should hand this to a purpose-built tool.

What the alternative costsNo priced human alternative is provided in the available tool information.

If this goes wrong, transactions can be assigned to the wrong expense account or VAT treatment and contaminate your management accounts or records.

What to actually do

  1. Use a tool built for this

    The route this page recommends

  2. Do it yourself

    Second choice

    A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

    How to actually do it

    1. Open your bank, card or expenses system and export the relevant transactions as a spreadsheet or CSV, keeping the date, description and amount columns.
    2. Gather the receipts or invoices for those transactions and remove unnecessary personal or account information before sharing them with an AI tool.
    3. Open your organisation's chart of accounts, expense policy and any VAT guidance, then paste the permitted categories and rules into the prompt.
    4. Paste the transaction data into the prompt and ask the AI to produce the categorisation table, totals and exceptions list.
    5. Compare the grand total with the original bank or card export, inspect every low-confidence or exceptional transaction against its receipt, and correct the categories in your spreadsheet.
    6. Send the corrected category totals and unresolved items to your bookkeeper or accountant before using them for VAT, statutory accounts or a formal submission.

    Prompt

    Break down the following business expenses into useful categories for a UK organisation. Use only the information in the data and the category rules I provide. Do not invent suppliers, purposes, VAT rates or amounts. Preserve the original transaction date, description and amount. Return a table with: date, description, amount in pounds, category, confidence, and reason. Then provide category totals, a grand total, and a separate list of transactions that need my decision. Do not decide VAT treatment unless the source data explicitly states it. Check that the category totals add up to the grand total and flag any duplicate-looking transactions or missing information.

Category rules:

Expense data:
[PASTE A REDACTED BANK OR CARD EXPORT, RECEIPT LIST, OR SPREADSHEET HERE]

    Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

  3. Hand it to a person

    The distant third

    A person who owns the outcome does this end to end, worth it when the failure is dear.

What it gets wrong

  • It cannot know the business purpose of a vague transaction from a bank description alone.
  • It cannot reliably decide your organisation's policy for mixed, personal or unusual costs without rules and context.
  • It cannot establish VAT treatment when the receipt or supplier information is missing.
  • It can produce plausible categories while putting an amount in the wrong row, so the source total still needs checking.
  • It does not take responsibility for the records, accounts or VAT figures created from its output.

Even on a YES, the friction has a name: judgement under ambiguity and stakes of error.

How we scored this

Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.

FAQ

Can AI categorise my business expenses?
Yes. Give it a transaction export, your category rules and supporting receipts, and it can classify routine items and calculate category totals. Check vague, mixed and VAT-sensitive transactions yourself or with your bookkeeper.
Can ChatGPT sort my expenses into categories?
Yes, if you paste a clean transaction list and define the categories you want used. Ask it to preserve the original amounts, show its reasoning and separate uncertain transactions instead of guessing.
Can AI categorise expenses for my UK accounts?
It can prepare a categorised working file for UK accounts, but it does not replace the review needed for your records or VAT treatment. Use your own chart of accounts and have a bookkeeper or accountant resolve anything ambiguous.
Is it safe to upload my business expenses to AI?
Only share the minimum data needed and remove bank details, names and other personal information where possible. Check the tool's data-use settings and keep the original export and receipts so you can audit the result.
