Replace customer-restricted items with an approved substitute
Automatically replace restricted products with similar approved items before checkout. Ideal for B2B distributors and government suppliers who need to manage product restrictions and contract agreements without disrupting the buying experience. Some buyers must follow strict product guidelines. Instead of blocking restricted items, this app helps customers complete their purchase with a compliant substitute — keeping sales flowing and buyers satisfied.
Businesses selling to regulated or contract-based customers often face challenges of balancing product visibility with purchase compliance. This app helps overcome those challenges by ensuring restricted products don’t interrupt the buying process:
Prevents restricted item purchases
Avoids compliance issues and manual order edits
Reduces cart abandonment due to blocked products
Maintains consistent customer experience for new and existing customers
Keeps catalogs visible while protecting restrictions

One-to-one mapping of restricted items to approved substitutes
Configurable replacement logic in the BigCommerce backend
Front-end alerts via modal, banner, or redirect
Customer confirmation before substitution
Works with B2B Edition and custom pricing rules
A government supplier selling lab equipment restricts certain chemical products to approved customers. When an unapproved user adds a restricted item to the cart, the app automatically suggests a compliant alternative, preserving the sale while maintaining compliance. This allows the supplier to show their inventory to potential customers while giving them an immediate alternative.
