Supplier Invoices & Cost Review Practical guide
Compare Supplier Invoices Against the Quote That Was Accepted
Preserve the exact quote version and acceptance
The short answer
A quote may expire, exclude freight, or depend on volume and delivery terms. The fair comparison uses the quote accepted by the buyer, its validity period, the actual order, and the invoice's product and service scope.
How to approach it
Save the accepted quote and order confirmation before reviewing variance. If the vendor issued a revised quote, document who approved it and when; do not assume an old quote governs a later order.
- Identify the accepted quote and version date
- Compare SKU, quantity, price, fees, and delivery terms
- Record approval for any revision
Could this affect your business?
- Can you trace this charge to an approved order, accepted terms, and a delivery or service record?
- Would your review catch the same bill, a changed pack size, or a fee that appeared this month?
- Can a second reviewer reproduce the comparison from the original documents?
