Quote vs Invoice

Quote vs Invoice is the engine that matches a vendor invoice to the original quote, item by item. It flags each discrepancy, such as a price change, a quantity shift or an item on only one side, as justified, unsupported or overbilled, and computes the recommended payment amount, so you catch overcharges before you pay.

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."
