Your reviewers get the vendor packet beside high-value purchase requests, or a clear list of what's missing before they decide.
Your bill reviewers get the supplier invoice and any mismatches together before they decide what to approve.
Your finance team gets the approved order and signed supplier terms together, ready to review when an invoice arrives.
