Could you build this?
Partial While calling Stripe APIs to duplicate objects is straightforward, handling exact subscription migration with complex edge cases, zero double-billing guarantees, and webhook state machines requires specialized payments engineering.
What it would actually take: The architecture requires robust state machines with transactional idempotency, queuing workers (e.g., Temporal or BullMQ), and deep integration with Stripe's Billing, Invoicing, and Subscription Schedules APIs. The hard part is managing real-world billing prorations, grandfathered pricing, active discounts, multi-currency meters, and exact cutoff reconciliation without incurring accidental charges or service interruptions.
