Quote vs Invoice

Compare a vendor invoice against the original quote. Catches overcharges, unauthorized extras, duplicated line items, and pricing drift.

Engine Phase: Post-Award Runtime: 25-45 seconds Pro+

What it does

Quote vs Invoice matches a vendor invoice to the original quote item by item. Every discrepancy — price changes, quantity shifts, items that appear only on one side — is flagged as justified, unsupported, or overbilled. The engine also computes the recommended payment amount.

When to use it

Vendor invoice just came in — verify it matches the quote before paying.
Closing-out a vendor — match the final invoice to the cumulative approved quote.
Monthly AP review spot-check.

Troubleshooting

Vendor changed their line-item grouping between quote and invoice

Normal. Engine matches by description + quantity; click any row for the source excerpt to verify the match.

OVERBILLED on an item that's actually an approved change

The engine doesn't see change orders by default. Upload the CO as a third document or use the chat to note: "Item 12 is a CO-3 addition — not overbilled."
