Customer proofing should make the approved version obvious. The useful record is not just a screenshot; it is the file, revision, and production setup the customer accepted.
Email threads lose context. Screenshots get forwarded. By production time, nobody is fully sure which logo, thread color, or placement was approved.
The buyer experience should be simple enough to finish on a phone while still giving your shop the record it needs.
The handoff should preserve the approved state so production is not interpreting an image that changed three messages ago.
Do not promise the screen is the finished garment. Proofs should help customers approve design, placement, and thread intent while still acknowledging fabric and machine variation.
Continue into the specific checks, formats, and workflows.
