Building a SaaS product with a Shopify integration and trying to understand how billing is handled for App Store apps.

The Shopify app itself is free and acts mainly as an integration layer. The core SaaS product is paid and already has existing billing outside Shopify.

Question is:

If merchants discover/install through the Shopify App Store, is Shopify okay with:

• using Shopify Billing API only for Shopify-acquired users
• while continuing to bill direct website customers externally (Stripe, etc.)?

Or does Shopify expect all users of the platform to eventually move under Shopify billing once the app is listed publicly?
