Which of the following tasks is NOT typically used in managing supplier invoice workflow?

The task that is not typically associated with managing supplier invoice workflow is negotiating. In the context of invoice processing, the workflow primarily focuses on tasks directly related to the approval, management, and tracking of invoices once they are received. Approving invoices involves verifying the accuracy of the details against purchase orders or receipts, while holding an invoice may occur if there are discrepancies or issues that need to be resolved before payment can be made. Changing invoices might be necessary to correct errors or update information as needed.

Negotiation, on the other hand, generally pertains to the terms of engagement between the supplier and the purchaser prior to the issuance of an invoice, such as pricing, delivery schedules, or contractual agreements. This activity occurs earlier in the procurement process, before invoices are generated and processed. Thus, it falls outside the scope of tasks involved in managing the workflow of supplier invoices once they are received and entered into the system.
