The Integration Gap
What breaks when Stripe is bolted on, not built in
Most stores connect Stripe through a plugin and call it done. Six months later, finance is reconciling manually, refunds arrive with no context, and subscriptions silently fail.
Manual reconciliation
Finance exports CSV files from Stripe, cross-references against your order management system, and hunts for missing transactions every Monday. 6 hours per week, every week.
Silent webhook failures
A webhook fires, your endpoint times out, the event is lost. Orders get stuck in "pending payment" for days before anyone notices.
Subscription sync drift
Stripe cancels a subscription. Your platform still shows active. The customer gets product they haven't paid for. You find out from a chargeback.
Refund data black hole
Refunds processed in Stripe don't map back to original order records. Customer service can't confirm what was refunded without opening two systems.
No dispute workflow
A chargeback arrives. You have no automated alert, no evidence package, no system: just an email and a deadline you almost miss.
Multi-currency blindness
You sell in 4 currencies. Your reporting rolls everything into one. Finance has no idea if GBP or EUR is margin-positive. Pricing decisions made on bad data.
Automated reconciliation
Every Stripe payout maps to order records automatically. Finance reviews a clean report, not a spreadsheet battle. 6 hours saved per week, starting day one.
Resilient webhook handling
Idempotent endpoint design with retry queues and dead-letter logging. Every event is captured, processed once, and verified. No silent failures.
Real-time subscription sync
Stripe subscription events trigger immediate platform state changes. Cancellation, upgrade, pause: your system reflects reality within seconds.
Full refund traceability
Refunds write back to original order records with timestamp, amount, and reason. Customer service answers refund questions in one screen.
Dispute automation
Chargebacks trigger automated evidence collection: order data, shipping records, communication logs, packaged and submitted before you're even notified by email.
Per-currency reporting
Multi-currency payouts segmented by market. Finance sees margin, volume, and conversion rate per currency, not one number that hides everything.

API Surface
The integration architecture your operations team relies on
Redefine builds your Stripe integration as a documented, versioned, and testable API layer, not a script no one understands three months later.
Layer
Checkout API
Payment session creation
Layer
Webhook Layer
Event routing + retry
Layer
Billing API
Subscriptions + invoices
Layer
Radar + Reporting
Fraud + reconciliation
Checkout API: what gets built
Endpoint
POST /api/checkout/create-session: idempotent, versioned, documented
Error handling
card_declined, insufficient_funds, and 14 other Stripe error codes mapped to user experience states
Test coverage
Jest unit + integration tests with Stripe test mode fixtures. CI enforced.
Webhook layer: resilience guarantees
Idempotency
event.id stored on receipt. Duplicate deliveries processed once, silently dropped.
Retry logic
Exponential backoff: 1s, 4s, 16s. Dead-letter queue after 3 failures with alert.
Uptime target
Webhook endpoint target: 99.9% availability. Monitored with PagerDuty integration.
Billing API: subscription engine
Plan changes
Proration calculated and applied automatically on mid-cycle upgrades.
Dunning
Smart Retries enabled + custom dunning email sequence triggered on payment failure.
Tax
Stripe Tax attached to invoices, jurisdiction-aware, audit-ready.
Radar + Reporting: fraud and data layer
Radar rules
Custom rule set built for your order profile: block, review, or 3DS challenge based on risk score.
Sigma
Custom SQL reports scheduled weekly: payout reconciliation, currency breakdown, refund ratio.
Data export
Automated daily CSV to your data warehouse: BigQuery, Snowflake, or S3 depending on stack.
What You Get

Collectibles ecommerceBusiness-to-business + business-to-consumer platform
CollectPCS: Premium Collectibles Platform
CollectPCS serves both business-to-business and business-to-consumer buyers with high-value, limited-edition products. They needed payment infrastructure that could handle pre-orders, partial payments, and multiple fulfillment models, without a single order getting stuck or miscounted.
The problem
Standard ecommerce payment flows couldn't handle pre-orders with partial captures, manufacturer-direct international fulfillment, and flexible plan billing simultaneously. Manual reconciliation was consuming 8 hours of operations time weekly, and still missing transactions.
The result
Flexible payment automation, controlled inventory release, and full payout reconciliation shipped and running. Operational confidence restored. Finance reconciles in minutes, not days.
Solution delivered
- Custom partial-capture payment intent flow for pre-orders
- Multi-model fulfillment with real-time shipping and tax logic
- Automated payout-to-order reconciliation for finance
- Admin-controlled inventory release tied to payment capture

Questions
Real questions before signing a brief
Plugins connect your cart to Stripe for checkout. They don't build reconciliation, webhook resilience, subscription sync, or dispute handling. Every store outgrows a plugin the moment payment complexity increases: partial captures, multi-currency, refund tracing, or subscription lifecycle events. Redefine builds the layer that sits between Stripe and your entire stack, not just checkout.
Most Stripe integrations go live within 8 to 21 days depending on scope. A focused checkout plus webhook layer takes 8 days. Adding subscription lifecycle, multi-currency, and reconciliation layer takes 14 to 21 days. You get a day-by-day sprint plan before any code is written.
Yes. Redefine starts with an audit of your current Stripe setup: endpoints, webhook handling, reconciliation process, and error coverage. We scope only what needs to be fixed or added. You don't rebuild what works; you strengthen what's brittle.
You own everything. All code, all documentation, all test suites transfer to your repository on handoff. There's no Redefine dependency, no subscription, no module you have to license. Your internal team can extend, modify, or hand it to any engineer after delivery.
Non-standard stacks are where Redefine specializes. Headless storefronts, custom Node.js backends, proprietary order management systems, multi-tenant platforms: the Stripe integration pattern adapts to your architecture, not the other way around. The scoping call maps your stack first, before any approach is recommended.
Is This Right for You?
This is a good fit if you recognize any of these
Good fit
Your finance team reconciles payments manually every week
You've had webhook failures that caused stuck orders or missed payments
You're adding subscriptions, multi-currency, or pre-orders and the current setup can't handle it
You want the code fully owned and documented by your team after handoff
Not a fit
You need a no-code Stripe connection for a landing page or basic checkout: a plugin is the right answer
Your transaction volume is under 50 orders per month: the operational complexity doesn't justify a custom layer yet
You need someone to maintain the integration on an ongoing basis: Redefine delivers and transfers, not retains
