Checkout Eligibility & B2B Access Control App

81% Confidence Medium Market Hard Difficulty $5k-15k MRR Updated Jul 19, 2026

The Opportunity

An app that restricts certain products or price tiers to approved customers only, based on tags or account status, and can optionally add prerequisite items to cart. It would help merchants enforce B2B-only access or special ordering rules without custom development.

"Merchants need to prevent regular customers from checking out with certain expensive or restricted products while allowing tagged B2B customers to proceed."

Detailed Analysis

Proposed Solution

Provide product- and customer-tag-based checkout gating, conditional add-to-cart rules, and automatic cart modifications for approved buyers. The app can block or redirect unauthorized shoppers, show access messaging, and integrate with Shopify Flow or checkout rules where possible.

Target Audience

Shopify merchants selling B2B-exclusive products, gated catalogs, or high-value restricted items

Competitive Landscape

Locksmith, B2B/wholesale access control apps, Locksmith-like gating tools, some wholesale suite apps

Implementation Notes

Require customer tag checks, product tag or price-based rules, cart validation, and possibly checkout extensibility or app proxy messaging. Since Shopify checkout blocking is constrained, use theme/cart validation plus Shopify Functions or checkout UI extensions where available; also support automatic bundle/add-on insertion when allowed.
