Stripe Integration - Payment Processing Specialists

Stripe processed $1.9 trillion in payment volume in 2025 — a 34% increase from $1.4T in 2024, equivalent to roughly 1.6% of global GDP. This scale matters to businesses adopting Stripe because it validates infrastructure reliability (Stripe processes 500M+ API requests daily with high uptime), fraud detection quality (Radar ML trains on all Stripe transaction data), and long-term financial stability ($159B valuation). When your payment infrastructure processes as little as $1M/year, you're running on the same infrastructure as Dow Jones and Nasdaq 100 companies.

Stripe Billing is the subscription management platform built on top of Stripe Payments. It handles: subscription creation and lifecycle, pricing plans (flat, tiered, metered/usage-based), free trials, coupons, proration on plan changes, Customer Portal for subscriber self-service, and dunning (automatic retry for failed renewals). Use Stripe Billing when you have any recurring revenue model — monthly/annual SaaS, subscription boxes, or usage-based billing. 200M active subscriptions for 300K+ companies validate it at every scale.

Stripe Connect enables payment splitting for marketplace and platform businesses — where your platform collects from buyers and distributes to sellers or service providers. Use Connect when: you're a marketplace (Airbnb, Uber model), a platform taking a fee from transactions, or a service business with multiple vendors. Connect handles seller KYC/onboarding, payment routing with fee deduction, payout scheduling, and 1099 generation for tax reporting.

Stripe Link is a checkout wallet with 200M+ pre-registered users. When a Link user reaches your checkout, they authenticate with a one-time code and complete purchase with their saved payment method — no card number entry. Merchants enabling Link report 16% higher conversion rates on average compared to standard checkout forms. Link is enabled as an option in Stripe Checkout or Stripe Elements with minimal additional integration work.

Development cost depends on payment flow complexity (one-time vs subscriptions vs marketplace), Stripe products required (Billing, Connect, Tax, Issuing), frontend framework, backend language, and any data migration. Stripe's platform itself charges 2.9% + 30¢ per transaction (lower with volume). Share your requirements and we'll provide a project-specific development breakdown.

European payments under PSD2/Strong Customer Authentication (SCA) require 3DS authentication for many transactions. We implement Stripe's Payment Intents API which handles 3DS automatically — detecting when authentication is required and redirecting the customer through the authentication flow without manual 3DS redirect logic. We test against Stripe's test cards for 3DS scenarios (required, not required, failed) to ensure the complete payment flow works in every European payment scenario.

Stripe webhook security requires: signature verification (using stripe.webhooks.constructEvent() with your webhook secret to prevent spoofed events), idempotency key implementation (storing event IDs to prevent duplicate processing on retry), event ordering handling (Stripe webhooks aren't guaranteed to arrive in order), and failure monitoring with alerting. We implement all four in every production Stripe integration — missing any one can cause duplicate charges or missed payment processing.

Yes, and it's one of the best-supported combinations. We use Stripe's official Next.js integration with: Stripe Elements in client components for custom checkout UI, Payment Intents API server-side in Next.js API routes or Server Actions, Stripe Checkout for hosted checkout pages, webhook processing in Next.js API routes with signature verification, and the Stripe dashboard's metadata for order management. Stripe also has an official Next.js starter template for new projects.

Stripe Radar is ML-based fraud detection that runs on every Stripe transaction. It trains on transaction patterns across all 5M+ Stripe merchants, adapts to your specific business's baseline, and blocks suspicious transactions. Default Radar rules block obviously fraudulent activity; custom rules let you add business-specific logic (block specific countries, require 3DS above certain amounts, flag velocity patterns). Radar Team adds manual review queues for borderline transactions.

Our Stripe support packages cover Stripe API version upgrade testing and migration, new Stripe product integrations (adding Stripe Tax, expanding to Connect, implementing Stripe Issuing), Radar rule refinements based on fraud pattern analysis, webhook monitoring and incident response, subscription lifecycle edge case handling, and compliance updates for regulatory changes (SCA updates, new PSD2 requirements).
