AI Invoice Processing and Accounts Payable Automation

Summary

Manual AP means opening each invoice, typing in the vendor, amount, and due date, choosing a GL code, and chasing approvals. That’s slow, and typos turn into late or duplicate payments. AI-based AP tools read invoices sent to a dedicated email inbox, suggest coding based on how you coded that vendor before, and route each bill to the right approver. They then sync everything to QuickBooks, Xero, or NetSuite, leaving people to review the exceptions instead of keying in data.

Take 3 recent vendor invoices (PDFs or photos), remove bank account details, and upload them to ChatGPT or Claude with the prompt below. Compare the output with how you actually entered those bills.

Extract the following from each attached invoice and return a table with one row per invoice:
Vendor name | Invoice number | Invoice date | Due date | Subtotal | Tax | Total | Currency | Line items (description + amount)

Then suggest an expense category for each line item from this list: [paste your chart of accounts or top 15 expense categories].
If any field is unclear or missing, write "CHECK" rather than guessing.
