Spot supplier price changes before approving an invoice

A useful starting point

An invoice comparison should highlight differences from an agreed price list without deciding that the supplier is wrong. Compare matching product IDs, units and effective dates. AI can help read source documents; the purchasing lead resolves commercial exceptions.

A worked example

Suppose the approved price is $24 per box and an invoice shows $27. The review row should contain both prices, quantity, price-list date and the invoice reference. Separate freight and taxes from item price so an added delivery charge does not appear to be a product increase.

Implementation and review

Use validated unit labels and a dated price table. Ask your accounting provider whether an existing purchase-order match can do the job. Test volume discounts, substituted products and a price change approved after the order date. The output is an exception report, never an automatic refusal to pay.

Excel supports controlled input values. The business workflow is an implementation proposal. Microsoft: data validation

Measure the improvement

Track review minutes and confirmed discrepancies, including false alarms. Do not count every flagged difference as money saved. Compare resolved discrepancies and recovered staff capacity with implementation, subscription and maintenance costs. Start with one supplier whose item codes are consistent.
