Add engraving, gift wrap, monograms, and paid add-ons to your products. When an option costs extra, OptionProof makes sure that charge actually reaches the order. Every release is tested against a real checkout, so the price shown is the price charged. Options render as a theme app block, so no theme code is injected. Your option sets stay in your own shop and export to a file any time, including when you leave.

• Add-on prices verified against a real checkout before every release
• Theme app block: no code injected, nothing left behind if you uninstall
• Option sets stay in your shop and export to JSON any time, even at cancel
