Multi-Merchant Direct-Billing App for Shopify SaaS
The Opportunity
A billing and access-management layer for unlisted Shopify public apps that sell directly to merchants outside the App Store. It helps SaaS vendors charge merchants via Stripe or another payment processor while still using Shopify OAuth for multi-store access.
"SaaS providers building direct-install Shopify integrations need clarity and tooling around how to bill merchants outside the Shopify App Store, especially when scaling beyond a single custom app."
Market Validation
Detailed Analysis
Proposed Solution
Provide a compliant billing bridge that connects Shopify OAuth installs with external subscription billing, usage tracking, entitlements, and merchant account management, while supporting unlisted public app distribution.
Target Audience
SaaS vendors, agencies, and B2B app developers selling Shopify-connected services directly from their own websites.
Competitive Landscape
Shopify Billing API, Stripe Billing, Chargebee, Recurly, Paddle, AppCharge, custom in-house billing systems
Implementation Notes
Create an OAuth-based install flow for unlisted public apps, store merchant entitlements, and sync subscription status from Stripe or another PSP to app access controls. Include usage metering, webhook-driven renewals/cancellations, invoice history, and billing status checks so merchants can be blocked or downgraded safely when payment fails.

"For an unlisted public app distributed exclusively via direct install link, are we required to use the Shopify Billing API for charging merchants?"
