File signed agreements, keep order receipts, bundle handoffs. Every one is ready to run, and you can adjust it in plain language.
File missing certificates beside signed agreements.
Keep signed agreements ready for handoff, with signature certificates or audit trails beside them and a clear note when proof is missing.
Match signed agreements to certificates and file both.
Your executed deals end with the signed agreement and signing certificate on the account, plus file links emailed to the deal owner.
