Shopify's native subscription capabilities presented several limitations
Platform Constraints
- 1 Subscriptions were limited to up to 3 variants per product.
- 2 No support for multi-product selection within a single subscription plan.
Client Requirements
- A Customers to select different products from a collection.
- B Combine them into a single subscription cycle.

Without custom development, Shopify could not meet these requirements.
The core limitation: Shopify does not natively allow customers to subscribe to multiple products under a single plan
