Check requests, collect missing files, open approval tasks. Every one is ready to run, and you can adjust it in plain language.
Request a missing supplier W-9 on the returned contract task.
Your requesters get a clear W-9 correction email. Their contract tasks wait in your needs-documents section with a comment.
Attach missing supplier files to the existing approval item.
Your reviewer sees missing files on the pending approval item, even when a requester adds them after the review starts.
