As of 13 August 2026, AI can check your expenses for errors.

What to actually do

1. Hand it to a person

   The route this page recommends

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

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

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

   How to actually do it

   1. Open the company expenses policy and your expense spreadsheet, then remove unnecessary personal details such as full card numbers before sharing anything.
   2. Gather the receipts, invoices, bank or card statements, approval records and currency details covering the same claims as the spreadsheet.
   3. Paste the policy and expense table into a chatbot, attach the supporting documents, and use the prompt above.
   4. Answer the chatbot's missing-information questions by supplying the relevant document or stating that it is unavailable, without asking it to guess.
   5. Open each flagged source row and compare the amount, date, merchant, currency, receipt and policy wording against the original document.
   6. Send the checked exception list to the authorised manager or finance contact, and update the expense system only after they approve the disputed items.

   Prompt

   Check the expense records below for possible errors using the attached receipts, bank or card records, and company expenses policy.
   
   Return a table with these columns: source row or receipt reference, issue type, amount, reason it was flagged, evidence used, confidence, and action needed. Look specifically for duplicate claims, missing receipts, mismatched dates, mismatched amounts, arithmetic errors, unusual currencies, personal items, claims outside the policy, missing approvals, and possible VAT or tax issues. Do not decide that an item is fraudulent or definitely disallowed. Separate clear data mismatches from items that need a human policy or tax decision. Do not invent missing facts, rates, categories or policy rules. Quote the relevant policy wording where available. Show the checks you performed, list items with no apparent error separately, and identify any records that were not supplied. Use pounds where the source uses pounds and preserve the original currency elsewhere.
   
   Company policy:
   [PASTE POLICY]
   
   Expense spreadsheet or table:
   [PASTE EXPENSE DATA]
   
   Receipts and supporting records:
   [PASTE OR ATTACH DOCUMENTS]
   
   Bank or card records:
   [PASTE OR ATTACH RECORDS]
   
   Before producing the final report, ask concise questions for any missing input that prevents a reliable check. Do not include unnecessary personal or bank account information.

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