Development / Payments
Payment gateway integration that protects conversion
(and reduces failed payments)
A "working" payment gateway isn’t the same as a high-converting checkout. Payment issues show up as subtle drops in conversion rate, rising failed payments, broken tracking, and support tickets that eat your team alive.
We integrate and optimize payment gateways with a growth lens: faster checkout UX, resilient API/webhook handling, correct tax/shipping totals, and tracking-safe releases-so payments don’t become the bottleneck as you scale.

What we deliver (payment integration done properly)
We build payment flows that are stable, compliant, and measurable-so checkout improvements translate into revenue, not surprises.
-
Fit for market
Gateway selection + setup
Stripe, PayPal, Adyen, Klarna, 2Checkout, local methods, wallets-aligned to region, AOV, risk, and your business model.
-
Conversion protection
Checkout UX + validation
Reduce friction: clearer error states, better form UX, correct totals, and edge-case handling (coupons, shipping, VAT, multi-currency).
-
Failure-safe
SCA/3DS + webhook reliability
Implement SCA/3DS correctly and build idempotent webhooks, retries, and reconciliation-so orders don’t get stuck and data stays consistent.
-
Trust the data
Tracking-safe checkout events
Ensure purchase events, revenue values, and attribution remain accurate across gateways-especially when checkout steps or redirects change.

Validate requirements, ship safely, measure impact
Payment work is high-risk because it touches revenue, trust, and attribution. We align on requirements, implement with guardrails, QA across scenarios, then measure results so improvements compound.
Discovery & risk mapping
Map current payment flow, failure points, and reporting gaps-then define acceptance criteria for conversion and order integrity.
Implementation with guardrails
Contract-first integration patterns, secure auth, and robust webhook processing-so your store stays stable under real-world load.
QA across scenarios
QA for success/failure paths, 3DS/SCA, refunds, subscriptions (if relevant), and analytics events-so "edge cases" don’t become revenue leaks.
Measurement & ongoing ownership
Post-launch monitoring and iteration-so you can improve approval rates, reduce failed payments, and keep checkout reliable over time. (Pair with eCommerce Maintenance.)
