Checkout Block Rules by Order Source

67% Confidence Medium Market Medium Difficulty $3k-8k MRR Updated May 19, 2026

The Opportunity

A Shopify app that lets merchants conditionally show checkout or post-purchase content based on order source attributes like Buy Button, Draft Order, sales channel, checkout type, and source name. It would help stores personalize messages, offers, or compliance notices only for the right order origins.

"Merchants using Checkout Blocks cannot reliably target custom messages or checkout content based on where the order came from, especially Buy Button and Draft Order flows."

Detailed Analysis

Proposed Solution

Provide a rules engine for checkout and post-checkout content that exposes order-source and sales-channel fields as conditions, with simple presets for common cases like excluding draft orders or Buy Button traffic.

Target Audience

Shopify merchants using Checkout Blocks, Shopify Plus stores, and merchants selling through multiple channels or embedded Buy Button flows

Competitive Landscape

Checkout Blocks, other checkout customization apps, custom app-built checkout extensions

Implementation Notes

Build a Shopify app with checkout UI extension support and a rules builder that reads available checkout/session/cart signals, maps order source proxies where direct fields are unavailable, and stores merchant-defined conditions for rendering post-payment or checkout content. For Buy Button detection, support proxy flags from cart attributes, landing-page/session markers, or app-managed tags; for draft orders, detect and gracefully skip unsupported flows; include validation/testing tools so merchants can preview which conditions will fire.
