A vendor bill shows a higher unit price than the PO. Before asking AP to approve the difference, check whether the buyer approved a price change, the invoice uses another unit of measure, or a separate charge was added to the line.
Compare the price and quantity separately
Pull the approved PO version, item receipt and vendor bill for the disputed line. Put the quantity, unit of measure, unit price and currency side by side. If the billed price differs, ask the buyer for the amendment or rate card that supports it. If the quantities differ, involve receiving. Keep freight and other charges visible so they don’t look like a change to the item price.
NetSuite distinguishes bill price, quantity and exchange-rate variances. Oracle documents different posting workflows depending on whether the line uses Match Bill to Receipt. Under the PO-line method, the line must be fully received and billed before generating variances. Check the method in use before treating a missing variance journal as evidence that the bill matched.

Test one recurring difference
Use a supplier whose small price differences recur. Compare several invoices against the effective date of the last approved price change. A one-off error can go back to the supplier. A repeated difference might mean purchasing needs to update the order or renegotiate the charge. Record the decision before changing a tolerance.
