PO vs Invoice Check

Upload a purchase order and your draft invoice. See exactly which fields and line items match before you send it, so a mismatch doesn't get your invoice bounced.

Also called a PO invoice matching check or a pre-send 2-way match - same idea either way.

Frequently asked questions

What does this catch that I might miss manually?

A mismatched PO number, a different buyer or vendor name, a quantity or unit price that changed between the PO and the invoice, or a line item on one document that is missing from the other. These are the most common reasons a client’s AP department rejects or delays an invoice.

Is this a 3-way match tool?

This checks two documents - the PO and the invoice you are about to send. A full 3-way match also includes a goods-receipt record, which is typically an AP/procurement control on the buyer’s side, not something the invoice sender has.

Does this replace checking the invoice manually?

No - treat it as a fast first pass. Line items are matched by description or SKU, which can occasionally mismatch wording that a human would read as the same item. Always review flagged rows yourself before sending.

Is this check free?

Yes, 2 free checks a day with no signup, 5 a day once you share your email. No credit card.

Is my PO or invoice data stored anywhere?

No. Both files are sent for extraction and are not stored - nothing about them (image or extracted data) is saved on our servers. Only anonymous usage metadata (timestamp, file types) is logged to enforce the daily limit.
