Coexistence

Two systems, no fight: the old platform’s subscriptions shrink while yours grow.

If you’re switching, your store now carries two books: the old platform’s (every subscription sold before today) and yours (every subscription sold from today). This is a stable stage, not a countdown. The two don’t fight: Shopify lets each app pull the billing trigger only on the contracts it owns, so no contract answers to two apps and nobody gets double-charged. That is a Shopify permission rule, not a promise.

	The old book	Your new book
What it holds	Every subscription sold before today	Every subscription sold from today
Who bills it	The old platform, at its old fee	OpenSubs, at a 0% fee
When a card fails	Its retries and reminders run exactly as before	OpenSubs retries automatically; tune the schedule at Settings > Payment recovery
Where subscribers manage it	The old platform’s portal	Your portal, at /a/account
Where it’s heading	Only shrinks: natural churn retires it	Only grows: every new subscriber lands here

Two books also means two subscriber portals until you consolidate; that is the honest, temporary cost of this stage. Watch the old platform’s fee line shrink with its book, and when the math and your nerves agree, migrate the remainder. No deadline.

You are live for new orders

Somewhere ahead, a stranger subscribes. No ceremony. It lands exactly like your team’s orders did: three places, no drama, and at the next daily billing run the machine charges a contract you sold. That’s the whole event. The dev store proved the machine; today the machine started earning.

Next up: Migrate. When the old book’s remainder is ready to come over, the cards never move; we only change who pulls the trigger. The finish line looks just like today’s proof: the same daily billing run, charging a contract you moved.
