The Payment Stack for Order-Centric Commerce
Commerce is built on orders, not payments. Flint gives you one unified state for cart, checkout, fulfillment, and refunds, so you can stop reconciling and start shipping.
const order = await flint.orders.create({
customer: "sarah@example.com",
line_items: [
{
name: "Organic Coffee Beans",
sku: "COFFEE-001",
quantity: 2,
unit_price: 1999
}
],
discounts: [{...}],
fulfillment: [{...}]
})
// ✨ Payment, totals, refunds, fulfillments, items - all in one
// ✨ Single source of truthTrusted by forward-thinking commerce companies
Payment Integrations are a Nightmare
Traditional payment processors just move money. You're left building order management, tax logic, and reconciliation systems from scratch.
Spaghetti Code
Managing order state across checkout, webhooks, and your database is error-prone.
Legacy Payment-First APIs
Not built for modern commerce. Impossible to handle order concepts like multiple payments and fulfillments without extra complexity.
Reconciliation Hell
'Why doesn't the stripe charge match the cart total?' Be prepared to answer this daily.
Manual Calculations
Writing your own tax and discount logic? Hope you enjoy maintaining it forever.
Don't build a legacy platform
The industry is moving from raw payment processing to Order-Centric architectures. See what you miss when you stick to the old model.
Payment-First Model
Fragmented state scattered across your database, Stripe, and tax providers.
- Manual reconciliation scripts required
- "Dumb" transactions (no line-item context)
- Complex split-payment logic
- Impossible for AI agents to navigate efficiently
Order-Centric Model
A unified source of truth for the entire lifecycle of commerce.
- Zero reconciliation needed (it's all in one object)
- Rich context (Items, Tax, Shipping, Meta)
- Native multi-payment & split support
- AI-Ready state machine
