About the OptionProof

Add custom product options and priced add-ons to your Shopify store with verified checkout accuracy. OptionProof lets you offer engraving, gift wrap, monograms, and paid add-ons that charge correctly every time. Each add-on price is tested against a real checkout before release, ensuring customers pay exactly what's shown. The app uses a theme app block, so no code gets injected into your theme—nothing is left behind if you uninstall. Your option sets remain in your shop and can export to JSON any time, even when you cancel. Perfect for stores needing reliable product customization with accurate pricing at checkout.
