File signed agreements, keep order receipts, bundle handoffs. Every one is ready to run, and you can adjust it in plain language.
Flag older visual proofs before the next review handoff.
Know whether the proof you're about to share is current, with the latest stored version and a clear send or hold reply in your chat thread.
Invite proof reviewers and record the revision shared with each one.
Your reviewers get the proof link, while your review ledger shows which revision you shared with them.
