Big-bang rewrites create risk in every payment path at once.
Shift workflow ownership into Flint while Stripe keeps moving the money underneath.
What This Page Answers
How do we migrate off Stripe-centric app logic without rewriting the whole stack at once?
Treat the migration as a state-ownership move. Keep Stripe for card processing, but move orders, checkout, refunds, and billing lifecycle into Flint one workflow at a time.
Most migrations fail when teams try to swap every payment primitive at once instead of changing which system owns the business truth.
Migration Shape
The safest migration keeps Stripe and replaces the glue around it
You do not need a processor cutover to stop living inside PaymentIntent-centered application code. The first win is moving business truth into orders, invoice records, and hosted collection surfaces that survive beyond one charge attempt.
Stripe is fine. The surrounding application glue is what keeps growing.
Stripe remains the rail. Flint becomes the public commerce model above it.
Most Stripe migrations are really attempts to escape the application layer that grew around Stripe.
The pain is usually not that Stripe cannot charge a card. The pain is that your app now owns too much state around the charge: order tables, pricing math, refund reconciliation, hosted flow bookkeeping, invoices, and recurring billing glue.
A good migration path does not start by asking which endpoint to replace first. It starts by asking which workflow creates the most operational drag today: hosted checkout, remote collection, refunds, B2B invoicing, or recurring billing.
Flint gives a staged path. Keep Stripe processing underneath. Move one workflow at a time onto Flint's public order-backed model until the application no longer has to be the glue layer.
Where Migrations Go Wrong
These are the common mistakes that make a migration harder than it needs to be
Swapping payment rails before swapping state ownership
Teams spend time reworking processor details while leaving orders, refunds, and hosted flow state in the same fragmented application model.
Moving every workflow together
Checkout, links, subscriptions, invoices, and refunds all shift at once, so every edge case appears in the same release window.
Treating migration as a code-porting exercise
The team ports old concepts one-for-one instead of changing which object owns the truth.
Migration example
The first migration win is replacing charge creation with order creation
Once the order becomes the durable record, hosted flows, refunds, and later billing can stop branching into separate systems.
const paymentIntent = await stripe.paymentIntents.create({amount: 6384,currency: "usd",metadata: { order_id: "internal_1042" },});// Stripe now knows charge state.// Your app still owns:// - line items// - discounts// - tax math// - refund allocation// - customer-facing order history
const order = await flint.orders.create({line_items: [{ name: "Coffee Beans", quantity: 2,unit_price_money: { amount: 1999, currency: "USD" } },{ name: "Pour-Over Mug", quantity: 1,unit_price_money: { amount: 2400, currency: "USD" } },],discounts: [{ coupon: { coupon_code: "WELCOME10" } }],});// Flint computes totals and keeps the record:// order.net_amounts → subtotal, discount, tax, paid, balance// order.activities → every state change// order.payment_intent_ids, refund_ids, checkout_session_ids
Migration Plan
Pick the workflow boundary first, not the endpoint list
Each step should remove one class of glue code from your application and replace it with a stronger public model.
| Capability | Stay on Stripe-centric app glue | Move the workflow to Flint |
|---|---|---|
Hosted checkout Specific order-linked collection pages | You create a session, then rejoin it to your own order truth | Checkout stays attached to the order record from the start |
Remote collection Reusable hosted flows and operator-sendable links | Payment requests live beside the rest of your billing model | Payment links live in the same platform as checkout and invoices |
Refunds What support and finance read after money moves back | Processor refund plus internal repair work | Refund is part of the same public workflow model |
Invoice collection Receivables, reminders, manual settlement | Often a separate billing subsystem | Hosted invoice payment and manual settlement on one invoice record |
Subscriptions Plans, signup, setup fees, trials | Adjacent billing product plus app glue | Recurring billing surface stays inside the same API family |
A practical migration shrinks the amount of business logic your application owns. That matters more than renaming endpoints.
This is a migration path, not a rewrite fantasy
Flint's public docs already show the staged surfaces you need for this move: orders, checkout sessions, payment links, invoices, refunds, subscriptions, and Stripe migration guidance.
That matters because migration pages are usually weak when the product can only make a vague promise. Flint can point to concrete HTTP routes and real hosted surfaces instead.
Recommended order
Migrate the highest-friction workflow first
Each step below narrows the blast radius and gives the team a cleaner checkpoint before moving to the next workflow.
Move one hosted flow first
Start with checkout sessions or payment links so you remove one obvious class of session and callback bookkeeping from your app.
Move refunds and support workflows
Shift post-payment operations onto Flint next so your team feels the operational benefit, not just the API difference.
Move invoice-led collection or subscriptions
Replace the next-biggest side-system once the core order-backed payment model is already working in production.
Reduce Stripe-specific app glue last
Once the workflows live on Flint, the remaining Stripe coupling in your application becomes much smaller and easier to retire.
Implementation
Use the migration docs to pick the first boundary
These are the docs that prove Flint can support a staged migration instead of an abstract platform pitch.
