Bold Product Options is a Shopify app that empowers fashion retailers to offer highly customizable product configurations without increasing complexity in the checkout process. The app provides a visual editor where merchants can add custom fields, dropdowns, checkboxes, and image swatches to product pages. This allows customers to personalize items—selecting colors, sizes, custom text, or add‑on services—right from the product page, enhancing the shopping experience and reducing cart abandonment. The app supports conditional logic, so certain options appear only when specific criteria are met (e.g., showing a monogram field only for certain apparel items). It also offers pricing adjustments based on selected options, enabling dynamic price changes that reflect the cost of customization. Bulk upload and import features streamline the process for stores with large catalogs. Bold Product Options integrates seamlessly with Shopify’s native checkout, ensuring accurate order data and inventory management.

For fashion brands, this tool is invaluable for creating personalized collections, limited‑edition drops, or seasonal customization options that differentiate a store from competitors.

For fashion brands, Shogun’s visual editor allows developers to craft look‑and‑feel that matches brand aesthetics, while marketers can experiment with layout variations to optimize conversion rates. Shogun integrates directly with Shopify, pulling product data, inventory status, and pricing into page elements. This ensures that landing pages reflect real‑time store information.
