Upproof adds a design upload to your product page and keeps each file with the order line it belongs to, even when two lines share a variant. From the order, send a proof with up to three options and its production details. Customers get the link by email or from you, pick an option and approve it, or request changes, with no account. Each proof is a numbered version, and a new one retires the old link. Before production, the approved version is checked against the current order and files.

• Customer design upload on the product page, bound to its order line
• Send up to three proof options; the customer picks one and approves it
• Private approval page by email or link, no customer account needed
• Numbered versions: a new proof retires the previous approval link
• Production card checked against the current order before you make it
