Selling custom products? A lost customer file means an order you can't produce, an awkward email chase, sometimes a refund. UploadProof is built to prevent exactly that. Customers attach their photo or design on the product page itself. Checkout, including Buy it now, politely waits until the file is in. Every file gets a permanent proof timeline: received, on the order, downloaded by you. Files stay safe for 90 days and you can download the originals anytime, just as the customer sent them.

• Upload widget on your product page: photos, designs, PDFs, drag and drop
• Required uploads gate checkout, including Buy it now and express buttons
• Delivery-proof timeline per file: received, attached to order, downloaded
• Files stored safely for 90 days; download originals anytime, byte-perfect
• Adds as a simple theme block; no code edits, nothing changed in your checkout
