Optionfier: Options & Bundles

Custom product options that keep stock in sync. 23 option types: swatches, text, file uploads, dates, email, phone, URL & more. Priced add-ons like gift wrap and engraving link to real products, so stock goes down when they sell and sold-out choices grey out on their own. Conditional logic shows the right options at the right time. Also in the app: native mix-and-match cart bundles, build-a-box (BYOB) with every item customizable, inventory sync & POS. One theme block, works with any theme.
