Stripe & Payment Integrations

Hands on Keyboard

We design and build the Stripe integration end-to-end, or embed alongside your dev team to ship faster.

Sometimes the right answer isn't a roadmap - it's people on keyboards getting the integration shipped. Hands-on-Keyboard engagements are how we deliver bespoke Stripe integrations end-to-end, or embed alongside an existing dev team to ship faster than they could on their own.

Every engagement is led by a Stripe-certified architect and resourced with experienced engineers from our Dublin, Alicante and Valbonne teams. We bring the platform expertise; you keep the product context.

Embedded with your team

We drop into your existing stack, sprint cadence and Slack channels. We take ownership of the Stripe-specific work while your team keeps building the rest of the product.

Velocity goes up, risk comes down

Pairing with your engineers throughout

Knowledge transfer baked into the cadence

Across every Stripe surface

Bespoke checkouts

Payment Element-based checkouts tuned for conversion, with Stripe Tax and Radar wired in.

Connect platforms

Multi-region marketplaces with tuned KYB onboarding, payouts and split funds-flows.

Billing & subscriptions

Subscription Schedules, replay-safe metered usage and dunning that actually recovers revenue.

Stripe Terminal

Server-driven Terminal integrations with branded apps and custom metadata for in-person.

Webhooks & reconciliation

Idempotent webhook handlers, queue-backed processors, and clean reconciliation against finance.

Bespoke products on Stripe

Custom rent-collection, MT940 handlers, branded payment-link landing pages - the bits Stripe doesn't do.

How a build runs

Brief

We get deep on your business, your stack and your constraints - finance, ops, compliance.

Design

Architectural decisions are agreed before code lands. Trade-offs are explicit, written down, signed off.

Build

Sprint cadence, paired engineering, frequent demo-able milestones. No waterfall surprises.

Handoff

Docs, runbooks, dashboards and an agreed support window so your team owns it with confidence.
