Check supplier invoices against what arrived
Finance chases purchasing and the warehouse to explain an invoice difference.
For finance teams needing purchasing and warehouse evidence before invoice approval.
What good looks like.
An approver can trace every material variance to the order, receipts and proposed resolution.
- Starts when
- A supplier invoice arrives or fails the normal match.
- Accountable owner
- Accounts payable lead
Where AI could help.
AI could extract invoice lines and draft variance explanations with references. Finance verifies amounts and authorizes payment separately.
How the work could move.
A suggested process to adapt to your team. Each handoff needs a clear owner and a visible check.
Establish identity
AP analyst
Record supplier, invoice number, currency and PO reference; check prior invoices and credits.
Ready when: The invoice is not a duplicate and its supplier matches the order.
Match line evidence
AP analyst
Compare quantities, prices and charges with approved PO versions and accepted receipt quantities.
Ready when: Matched and unmatched amounts add to the invoice total.
Investigate variances
Buyer + receiving lead
Attach evidence for price changes, shortages, freight or tax differences and assign disputed lines.
Ready when: Each material variance has an explanation or an owner and deadline.
Record disposition
Finance approver
Approve, hold or dispute each exception; link expected credit or corrected invoice.
Ready when: The decision is documented without treating it as proof of payment.
Explore the setup, checks, and exceptions
Start with your tools.
Join invoice lines, PO lines and receipt references in a review worksheet. Retain originals; approved accounting entries remain in the finance system.
When things go wrong.
- A partial receipt may justify holding only part of an invoice under approved terms.
- A replacement invoice must reference the superseded one to avoid double payment.
- A promised credit is not a received credit note.
A useful first step.
Assemble a packet with one quantity variance and one price variance; have the approver identify both from the record alone.
What to measure
Measure exception aging, repeat variance reasons and invoices returned for missing evidence.
