Handle Buyer-Requested Corrections to a B2B Invoice

Identify the requested change and the invoice state

Ask the buyer to identify the original invoice and the specific field or line in question. A request may concern a purchase order number, the billing entity, a line price, or a shipment quantity. Check whether the invoice is a draft, finalized, partly paid, or paid before deciding how it can be corrected.

Confirm the buyer’s authority for material changes

• Verify changes to billing contacts or entities through the established account contact.
• Check that price or quantity changes match the buyer-approved order record.
• Ask finance which correction document the system supports for the invoice state and what happens to previous payment requests.

Close the loop after the correction

Send the corrected invoice or credit document with a clear reference to the original. Record which invoice remains payable and confirm the buyer received the update. If funds were already received, verify that they were applied or returned according to the documented correction before requesting payment again.
