Change the Vendor or other Detail for an Unpaid Invoice

An invoice may sometimes be posted with the wrong vendor, expense account, or other detail. This article walks through the process of correcting a posted but unpaid invoice. In the example, an invoice was posted for "Wal-Mart Shopping Center" and displays on the Manage > Payment Processing page. The vendor needs to be changed to "Music Supply Warehouse," and the detail line needs a different expense account.
