Which component is not typically included in a supplier invoice validation process?

In the supplier invoice validation process, the primary objective is to ensure that the invoice being processed accurately reflects the goods or services provided, as well as conforms to internal controls and agreements. The components involved typically include checking for documentation such as missing attachments, ensuring invoices match with company purchase orders, and possibly conducting a comparative analysis with previous invoices to identify discrepancies or patterns.

The confirmation of employee training records, however, does not relate directly to the supplier invoice validation process. This component typically pertains to HR and compliance functions, focusing on ensuring that employees have received appropriate training for their roles, rather than verifying financial transactions or validating invoices. Therefore, this process does not fit with the other options, which all focus on ensuring the accuracy and completeness of invoices as they relate to supplier transactions.
