Hidden Variant Option (VAT-Friendly)
The Opportunity
A theme app extension that lets merchants hide selected variant options (e.g., Option 3) from the product page while preserving the underlying variant IDs for inventory and accounting. It auto-selects the correct hidden value and keeps the storefront clean without breaking tax or ERP workflows.
"Merchants use a third variant option for internal VAT type (marginal, standard, commission) added by an inventory manager, but it appears on the product page and confuses shoppers."
Market Validation
Detailed Analysis
Proposed Solution
Provide a product-form replacement that suppresses designated options (globally or per product), auto-selects hidden values, and maps visible choices to the correct variant IDs. It preserves inventory, pricing, and accounting integrity while removing the extra selector from the UI.
Target Audience
Merchants using ERPs or inventory managers that inject internal-only variant dimensions, especially EU/UK stores with complex VAT schemes.
Competitive Landscape
Swatch King - Variant Options; GLO Color Swatch; StarApps Variant Options; theme customizations (non-app)
Implementation Notes
Build a Shopify theme app extension with a product-form app block that fetches variant data via Section Rendering and Storefront API, identifies a merchant-selected hidden option (e.g., Option 3), omits its selector from the UI, and auto-selects the default/only value. Maintain a mapping from visible selections to concrete variant IDs, filter sold-out combos, and support dynamic checkout and cart drawers via AJAX APIs. Provide admin UI to configure global/per-product hiding via metafields. Ensure no theme edits required, handle fallback with minimal CSS if JS disabled, and keep structured data and SEO intact.
