Platform Solution
Payments for vertical SaaS should match the workflow you already own
If your product already runs booking, front-desk, membership, or job workflows, Flint lets you add payments without standing up a second billing brain beside the rest of your software.
Vertical SaaS
Your product owns the workflow. Flint owns the payment layer underneath it.

Where Platform Teams Get Stuck
The first payment workflow becomes the billing architecture by accident
Most vertical SaaS teams start with one narrow collection need, then discover they have to support very different payment shapes without losing the product context they already own.
Different payment shapes arrive faster than expected
A platform that starts with a one-time checkout usually gets asked for deposits, later balances, recurring plans, or formal invoices soon after launch.
Support needs the business record, not just the charge
When users ask about a refund, skipped payment, or amount mismatch, your team needs the operational object that led to the payment, not an isolated processor event.
Merchant activation is part of product adoption
If merchant onboarding sits completely outside your app, payment setup starts to feel like a separate product instead of part of your platform.
Flint For SaaS Platforms
The payment stack fits products that already have workflow authority
Flint is strongest when the product already knows what the customer is buying and needs payments to stay subordinate to that workflow instead of replacing it.
Orders mirror your product state
Use order metadata and line items to keep the sale anchored to the workflow your application already owns.
Embedded plus hosted collection
Keep checkout in your own UI when needed, then use hosted sessions, links, or invoices for the flows that are easier to ship that way.
Recurring billing when the vertical needs it
Move from one-time collection into subscriptions without standing up a separate recurring billing surface from scratch.
Merchant onboarding in the same platform
Hosted and embedded onboarding flows help activation live closer to the rest of your product experience.
Refunds stay tied to the business object
Refunds and downstream reconciliation stay legible because the payment activity remains attached to the same order record.
A safer expansion path
You can start with one hosted or embedded workflow and still grow into a fuller commerce layer without replacing the model underneath.
Workflow
Start with the product record, then choose the collection surface that fits
That keeps payment implementation aligned with the software you are actually selling instead of forcing every workflow through the same narrow processor abstraction.
Create the order from your product event
Attach the booking, member, job, or account context to the order so the sale starts from something your team already understands.
Activate the merchant inside your product journey
Use hosted or embedded onboarding so payment activation feels like part of using the platform, not a separate detour.
Use checkout, links, invoices, or subscriptions as the workflow demands
The collection surface can vary while the record underneath stays consistent.
Keep support and finance on the same object later
That is where the order model pays off once the platform has real users and real exceptions to handle.
Example
const order = await flint.orders.create({
customerId: customer.id,
lineItems: [
{
name: "Initial evaluation",
quantity: 1,
unitPriceMoney: { amount: 12500, currency: "USD" }
}
],
metadata: {
platformAccountId: account.id,
workflowRecordId: visit.id,
workflowType: "intake_visit"
}
});
const session = await flint.checkoutSessions.create({
orderId: order.id,
successRedirectUrl: "https://app.example.com/payments/success",
cancelRedirectUrl: "https://app.example.com/payments/cancel"
});
// Later, the same account can grow into:
// - invoices for balances due
// - subscription plans for recurring programs
// - refunds against the original orderGood Fits
Vertical products that already own the workflow
The strongest fit is software that already manages the operational context and wants payments to deepen the product instead of fragmenting it.
Workflow-led SaaS
Products for scheduling, case management, field operations, or membership workflows that already define what is being sold.
Platforms moving from manual billing to embedded payments
Teams replacing offline collection, ad hoc Stripe usage, or patched-together invoice flows with something product-native.
SaaS with mixed one-time and recurring revenue
Products that need upfront fees, recurring plans, and occasional follow-up charges in the same account history.
Teams that care about the support surface early
When the product team knows from the start that refunds, receipts, and follow-up questions will matter.
Architecture Decision
The real choice is whether payments remain subordinate to your product
Vertical SaaS teams usually outgrow generic payment plumbing when the business record and the payment record drift apart.
