For a personalized order, the approved artwork needs to be easier to find than a draft. A simple file name that pairs an order reference with a version label makes the current decision visible to the next person handling the work.
Make revision status unmistakable
Use a short label such as draft, sent for review, approved, or revise. Keep the approval message or note beside the file, but do not turn a customer approval into a claim about material suitability or operating conditions.
When a change arrives after approval, preserve the earlier version and create a new one. Browse /updates/ for additional small-shop organization ideas.
