Stripe billing is more complex than the docs suggest. The edge cases are where revenue leaks.

Stripe subscription billing, metered usage, trial management, and upgrade/downgrade flows require careful implementation. Webhook handling, idempotency, and billing portal configuration are where most billing integrations break. We build Stripe billing correctly.

The problem
SaaS product with a broken or incomplete Stripe billing integration — missed webhook events, failed upgrade flows, or subscription state that doesn't match what Stripe shows

Stripe is the right payment processor for SaaS applications. The Stripe API is well-documented, the webhooks are reliable, and the billing capabilities cover subscription, usage-based, and one-time payment models. The problem is that Stripe billing implementations have non-obvious complexity that causes revenue loss when done incorrectly.

Webhook reliability. Stripe sends webhook events for every billing lifecycle event: subscription created, payment succeeded, payment failed, invoice finalized, subscription cancelled. If your application's subscription state is maintained by polling Stripe or by trusting only the checkout session, you will have billing state that diverges from Stripe's reality. Webhook handling with idempotency keys and event deduplication is required.

Failed payment handling. Stripe's dunning management (automatic retry on failed payments) is configurable. If you don't configure it and handle the invoice.payment_failed webhook, you're losing revenue to failed payments that should have recovered.

Upgrade and downgrade proration. When a customer upgrades from a $49/month plan to a $99/month plan mid-cycle, Stripe calculates proration. The application needs to handle the customer.subscription.updated webhook and update the customer's access level immediately.

Billing portal. Stripe's customer portal allows customers to manage their own subscriptions (upgrade, downgrade, cancel, update payment method). Configuring the portal correctly and linking to it from the application reduces support volume significantly.

What we build

Complete Stripe billing integration with subscription management, webhook handling, billing portal, and the idempotency that prevents duplicate charges

Checkout and subscription creation

Stripe Checkout or custom payment form for new subscriptions. Subscription creation with trial periods, discount codes, and plan selection.

Webhook handling

Webhook endpoint with event verification (`stripe.webhooks.constructEvent`). Handlers for all relevant billing events with idempotency keys. Database subscription state updated from webhooks, not from checkout session completion alone.

Failed payment handling

`invoice.payment_failed` handler with customer notification. Subscription access restriction after grace period. Dunning configuration in Stripe dashboard.

Upgrade/downgrade

Subscription update flow with proration display. Immediate access level change on `customer.subscription.updated`. Proration handling for mid-cycle changes.

Billing portal

Stripe customer portal configuration. Portal link generation from the application. Customer self-service for subscription management.

Three steps, every time.

The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.

01Week 0

Brief & discovery.

We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.

02Weeks 1–N

Build & ship.

Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.

03Post-launch

Warranty & retainer.

30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.

Why fixed-price

Why Fixed-Price Matters Here

Stripe billing integration scope is defined by the subscription tiers, the upgrade/downgrade flows, and the billing portal requirements. Fixed price.

FAQ

Questions, answered.

Stripe Checkout (the hosted payment page) is the right choice for most applications: it's PCI-compliant by default, handles card validation, and supports 3D Secure automatically. Custom payment forms (Stripe Elements) add complexity and require PCI compliance documentation. Use Checkout unless the UX requirements specifically require an embedded form.

Stripe Billing supports usage records via the `billing_meter` and `subscription_item` APIs. Metered usage is reported to Stripe at the end of each billing period; Stripe calculates the invoice. Implementation requires a usage recording mechanism (often a background job or event handler).

Included in the application build. Full SaaS with billing from $25k. Fixed-price.
