It is developed by Francesco Guiducci for IFG Development. ## At a glance - **Type**: Shopify app with a storefront builder - **Purpose**: Build Your Own Box and Mix & Match boxes - **Price**: Fixed, set by the merchant: it is the real price of the bundle - **Components**: Real catalogue variants, with inventory linked - **Theme integration**: Theme App Extension - **Developed by**: Francesco Guiducci, IFG Development - **Availability**: Shopify App Store ## The problem it addresses Anyone selling build-your-own packs, tasting sets or kits has a recurring problem: the customer picks the products, but the merchant wants the box to have a precise price. Many solutions reach the total with discounts applied to the components, which complicates cart, checkout and order analysis. IFG Build Your Box takes a different model: the box price is the real price of the bundle product and follows the builder, cart and checkout. Components are real catalogue variants, so inventory and orders keep their semantics. ## How it works - **1. The merchant sets up the box**: Defines the fixed price and the rules: minimum, maximum or exact number of units, limits per variant and per group of components. - **2. The customer builds the box**: The storefront builder, designed mobile-first, uses real catalogue variants and enforces the selection rules. - **3. The price stays the box price**: The same value follows builder, cart and checkout, without depending on a discount. - **4. Inventory stays consistent**: Components are real variants, so inventory and orders keep their semantics. ## Main features - **Fixed box price**: The merchant sets the box price and that same value follows the builder, cart and checkout. - **Real components**: Selection uses real catalogue variants, keeping product semantics and inventory. - **Min, max and exact rules**: The merchant can define how many units the customer must or may select in the box. - **Variant and group limits**: Rules can limit quantities per single variant and per group of components. - **Mobile-first builder**: The storefront experience is designed to be usable on small screens and inside theme sections. - **Theme App Extension**: The builder integrates with the theme through the Shopify tools dedicated to storefront apps. ## When it makes sense - **Tasting sets and gift boxes**: The customer chooses the products and pays the price the merchant set for the box. - **Kits with an exact number of products**: Minimum, maximum or exact rules prevent selections outside the intended format. - **Component groups**: Group limits make it possible, for example, to balance different categories within the same box. ## Scope and limits The product is not a generic bundle and upsell suite. Its scope is building boxes with a fixed price, real components and selection rules. Features that depend on specific Shopify capabilities must be checked on the actual plan and store. ## Frequently asked questions - **What is IFG Build Your Box?**: A Shopify app for building Build Your Own Box and Mix & Match boxes, with a fixed price, real components and selection rules.
