What we patch in your SaaS billing architecture:
Good fit if
SaaS founders and developers losing revenue and receiving angry user support tickets due to failed Stripe webhooks, ghost subscriptions, unhandled invoice failures, or out-of-sync customer portals.
Configuring App Router raw request stream parsing and cryptographic Stripe webhook signature validation to stop 400/500 errors.
Ensuring events like checkout.session.completed and invoice.payment_succeeded execute exactly once, even during Stripe retry storms.
Real-time syncing for upgrades, downgrades, cancellations, grace periods, and failed payment dunning notifications.
Reconciling missed webhook events directly against the Stripe REST API to retroactively provision paying users.
We pull your repository under strict bilateral NDA, reproduce the failure locally, and identify the root cause within 2 hours.
We deploy an emergency hotfix to stop data leakage, 500 errors, or crashes so your users and demo remain safe.
Senior engineers refactor brittle state, database schemas, and API contracts to prevent regressions.
Automated test suites, complete runbook documentation, and 30 days of post-launch warranty with 100% code ownership.
Questions we hear on discovery calls—answered plainly.
Next.js App Router parses request bodies by default. Stripe signature verification requires the exact, unmodified raw byte buffer. We configure request.text() handling with proper cryptographic verification.
We write a custom reconciliation script that queries your Stripe customer list, checks corresponding subscription records against your database, and safely provisions all missing entitlements without double-billing.
Stripe guarantees at-least-once delivery, meaning webhooks can fire multiple times for a single payment. We implement database-level idempotency keys so events are processed exactly once.
We treat billing failures as Tier-1 critical emergencies. A senior engineer can begin triage within 2 hours, with emergency hotfixes deployed within 24 to 48 hours.
