I used Vercel's Workflow SDK to power the durable workflows of this app, to ensure the Stripe migrations are done properly.

Hi Product Hunt, I am Simon, the founder of SubPorter.
Earlier this year I sold a small SaaS. I discovered Stripe copies cards across accounts, but does not move products, prices, billing meters, or active subscriptions. The existing migration tool cost €300, which made no sense for a small exit. I wrote scripts, handled the cutover by hand without double-charging anyone, and turned those scripts into SubPorter.
SubPorter replaces custom scripts with three verifiable safety gates: 1. The source account stays read-only during staging. 2. Subscriptions renewing within 48 hours, or with discounts, trials, past-due status, or complex tax settings, route to manual review rather than failing silently. 3. Destination subscription schedules anchor to real renewal dates before the source subscription is cancelled at period end. Both parties sign off and receive an audit packet.
What to try first: connect your test data or a read-only restricted key for a free planning run. You can inspect the catalog model and flagged review rows completely free.
I would love your feedback on our safety gates and audit workflow. What edge cases do you worry about most during billing handoffs?
