Stripe integration · Payments engineering

Free Stripe audit. Then we build what it reveals.

We review your current Stripe setup or your planned architecture at no cost and show you exactly what is leaking revenue, where the risk is, and what to build next. If you want it done, we scope a fixed engagement: Payment Element, Billing, Connect, webhooks, reconciliation, and fraud rules built properly from the start.

Why we start with a free audit

Most Stripe integrations are built to work, not to scale.

A first Stripe integration is usually wired together quickly: the happy path works, payments go through, and everyone moves on. Then the business grows, billing gets more complex, the first invoice dispute lands, and the gaps in the original work become expensive problems. Missed webhooks, broken reconciliation, no dunning, no fraud rules, no plan for a second currency or a marketplace payout model.

We look at what you have before quoting anything. The audit is free because it is the only honest way to scope the work: we map the gaps, estimate the revenue impact of each one, and tell you what to prioritise. If the numbers do not justify an engagement, we will say so. You keep the findings either way.

7/10
Stripe integrations we audit have at least one webhook handler that is not idempotency-safe. A single duplicate delivery can create a duplicate charge, subscription, or payout. It is the most common silent risk in production.
How it works

Four steps. The audit lands in a week.

No procurement loop, no open-ended retainer, no day-rate negotiation. The whole front end runs on one form and one call.

Tell us about your setup

Work email and a short description of what you are using today or what you are planning to build. Read-only Stripe dashboard access speeds things up, but it is not required.

We audit your integration

We map your current or planned architecture against Stripe best practices: webhook handling, subscription lifecycle, reconciliation flows, Connect topology if relevant, and Radar rule coverage.

Findings call

A short call to walk through what we found, the revenue and risk impact of each gap, and the order we would fix them. You keep the audit either way.

Scope and build

If you want it built, we scope a fixed engagement: a concrete deliverable list, a timeline, and a price before any work begins. You see exactly what you are buying.

What we build with Stripe

Three integration patterns, built to production standard.

Most payment engineering problems fall into one of three shapes. We have done all of them, and we know where each one hides its complexity.

Payment integration

Payment Element and Checkout for one-time and recurring payments, with full webhook handling for the complete payment lifecycle: succeeded, failed, disputed, and refunded. PCI scope reduction by design, not as an afterthought.

Billing and subscriptions

Stripe Billing for subscription products, usage-based and metered pricing, trial periods, plan upgrades and downgrades, proration, invoicing, Stripe Tax for automatic tax collection, and a dunning sequence that recovers failed payments rather than churning the customer.

Connect for platforms

Stripe Connect for marketplace and platform payout models: onboarding, identity verification, charge routing, split payments, transfer schedules, and the compliance layer for money movement across a network of connected accounts. We do not hold your funds. We build the integration that lets Stripe handle them properly.

Want the depth? Every one of these is broken down with architecture diagrams and implementation notes in the complete Stripe integration guide. This page gets you the free audit; the guide is the reference.

Sample audit finding

This is what one finding looks like.

Every item in the audit follows the same structure: what is wrong, the data behind it, the revenue or risk impact, and the exact fix ready to implement. The card on the right is illustrative. Your audit is built from your own integration.

This particular finding type appears in almost every production Stripe integration we review. It is quiet, it compounds, and it is straightforward to close once you know it is there.

STRIPE-007 · Webhook idempotency
High risk Fix: 1 to 2 days Affects: all events
Webhook handler processes events without checking for duplicates. Stripe retries on network failures.
What the data shows
invoice.payment_succeeded handler creates a subscription record on every delivery. Stripe retried 3 events in the last 30 days due to 5xx responses from your endpoint. Two of those retries created duplicate subscription rows in your database.
The fix
Store event.id in processed_events table on first delivery
Check for existing record before processing any webhook
Return 200 immediately if event already handled
Add unique constraint on (stripe_event_id) column
Engagement tiers

Sized to what you are building.

A focused payment page is a different scope to a full Connect marketplace. We match the engagement to the work after the audit, and you see the price before any work begins.

Proof

We have done this for companies like yours.

Payments engineering and integration work runs through a lot of what we build. A few that map closely to a Stripe engagement:

FAQ

Questions we get every week.

Do you handle money or hold our funds? +
No. We build the integration between your product and Stripe. Stripe holds and moves the funds; we build the code that connects your system to their APIs. You retain full control of your Stripe account and funds at all times.
How long does a Stripe integration take? +
A straightforward Payment Element integration with webhooks and basic reconciliation typically takes two to four weeks. Billing with multiple pricing models, a Connect marketplace, or a migration from another processor adds time. The audit tells you the realistic scope before any work starts.
Is the audit really free? +
Yes. We review your current setup or your planned architecture and deliver a findings document with gaps, risks, and a recommended roadmap. There is no charge and no obligation to engage us further.
Can you migrate us from another payment processor? +
Yes. We handle migrations from Braintree, PayPal, Adyen, Chargebee, and others. That includes mapping your existing plans and customers to Stripe objects, running a parallel period to validate, and managing the cutover so nothing drops.
Who writes the code? +
We do. Depending on the engagement, we write the backend integration code, the frontend payment UI, and the webhook handlers, or we work alongside your team and produce specs and review. Either way, the code lands in your repository under your ownership.
What does it cost? +
Scope drives price. A focused Payment Element integration is a different size to a full Connect marketplace. We scope precisely after the audit and give you a fixed number before any work begins, so there are no open-ended surprises.
