Stripe Integration — payments, billing, and Connect done correctly
Production-grade Stripe wiring — Checkout, Billing, Connect, Tax, and Radar — with the webhook reliability that keeps the books straight.
Stripe is the easiest payments API in the world to start with and one of the easiest to get subtly wrong at scale. The Checkout link works on day one; the bug that double-charges a customer because your webhook handler wasn't idempotent shows up in month six. The Stripe Connect onboarding flow seems simple until you need 1099-K reporting, dispute routing, and a way to roll back a payout that's already cleared. We build production Stripe integrations end to end: Checkout for one-shot purchases, Billing for subscriptions and metered usage, Connect for marketplaces and platforms, Tax for automated VAT/GST/sales-tax, Radar for fraud, and the back-office surface your finance team needs (reconciliation, refunds, invoice exports). Idempotent webhook handling is the floor, not the ceiling. We've shipped Stripe inside [CloudChat](/work/cloudchat) (subscription billing for a SaaS), [555 Group](/work/555-group) (Stripe Connect for a multi-merchant marketplace), and a dozen other production builds — the same patterns power every engagement.
About this service
Where Stripe goes wrong
Five places where the books quietly drift
After enough Stripe integrations, the same five bugs come up: webhook handlers that aren't idempotent (so a retried event creates duplicate records), missing reconciliation between Stripe's view of the world and your database's, currency rounding errors that compound over a year, plan-change proration handled in the UI instead of by Stripe Billing, and refund flows that don't update downstream entitlements.
We bake the fixes for all five into every integration we ship — not as features, as the default. Plus a finance-facing surface so your accountant doesn't have to log into the Stripe dashboard to find anything.
Where Stripe shines
Use the platform, don't fight it
Stripe Billing handles subscriptions, trials, proration, dunning, and tax — usually better than anything you'd build yourself. Stripe Tax handles VAT/GST/sales-tax across jurisdictions, registration tracking, and filing prep. Stripe Connect handles marketplace payouts and KYC. Stripe Radar handles fraud signals at a scale you couldn't replicate.
The mistake we see most often: teams building their own billing engine on top of raw Stripe charges, then years later trying to migrate to Stripe Billing under load. We'll tell you up front which Stripe products to lean on so the build is leaner now and cheaper to maintain later.
Adjacent surfaces
Often part of a SaaS build or API integration
Most Stripe engagements come bundled with the rest of a SaaS Development build, or as part of a broader API Integration engagement (Stripe + accounting + tax + CRM). We're happy to do Stripe in isolation, but if it's part of a larger build, we'll usually save you money by scoping it together.
Real stripe integration patterns we’ve shipped
Not adjectives. Specific shapes of build we’ve taken to production for clients like you.
Subscription SaaS billing
Plans, trials, proration, dunning, customer portal, plan changes, cancellation surveys — built on Stripe Billing, not a homemade billing engine.
Metered usage billing
Per-token, per-call, per-seat metering with overage handling, usage dashboards for end customers, mid-cycle plan migrations, end-of-month true-up.
Marketplace payouts (Stripe Connect)
Multi-merchant marketplace with split payments, automated payouts, KYC onboarding, dispute routing — like [555 Group](/work/555-group).
Stripe Tax + multi-jurisdiction VAT
Automated VAT/GST/sales-tax calculation across EU/UK/US/AU, registration thresholds, filing-ready exports, customer-facing tax IDs.
One-shot product checkout
Stripe Checkout for digital or physical products, with discount codes, regional pricing, post-purchase entitlements, and clean receipt branding.
Donation / pay-what-you-want
Flexible-amount Checkout, optional recurring conversion, donor receipts that meet your jurisdiction's tax-deductible requirements.
Refund + dispute back-office
Operator surface for finance team — issue refunds, respond to disputes, export invoices, reconcile against your accounting system.
Stripe Radar tuning + fraud rules
Custom Radar rules tuned to your fraud profile, manual-review queue, allowlist/blocklist management, chargeback rate tracking.
How a Stripe Integration engagement actually runs
Five concrete steps with deliverables. No retainer fog.
Pricing model design
Before any code, we model your real pricing: one-shot vs. subscription vs. metered, currencies, jurisdictions, tax handling, free tiers, promos. Output: a written pricing spec that maps directly to Stripe products/prices.
Checkout / Billing flow build
Customer-facing checkout, plan selection, signup-to-paid funnel. Stripe Customer Portal wired for self-serve plan changes and cancellation. Email receipts and confirmations branded to your domain.
Idempotent webhook layer
Every webhook handler is idempotent by event ID. Retries from Stripe are safe. Failed events are queued with backoff. Webhook delivery health surfaces on a dashboard you can watch.
Back-office + reconciliation
Finance-team surface for refunds, dispute responses, invoice exports. Nightly reconciliation job that compares Stripe's view of subscriptions and balances to your database's, with a Slack post when they drift.
Launch + 30-day audit
Public launch, then 30 days of monitoring with a focus on edge-case dunning (cards expiring mid-trial), tax calculation correctness, and dispute response SLAs.
