v3 — Approved & Locked

Jane Davis · Mar 15, 2026

Why It Matters

Version confusion causes client disputes

Without clear versioning, agencies can’t prove which version was approved. When a client says “I never approved that,” you need a locked, timestamped record — not an email thread. This is liability protection.

"Which version is the latest?"

When files live in email attachments, Slack threads, and shared drives, nobody knows which version is current. Teams waste hours tracking down the right file.

Approval disputes cost real money

A client claims they approved a different version. Without immutable records, it's your word against theirs. Agencies eat the cost of rework — or lose the client entirely.

Immutable versions are your proof

Every version is timestamped, labeled, and locked on approval. You can prove exactly which version was approved, by whom, and when. Disputes resolved instantly.
