Payment gateway integration done right the first time — Stripe, GoCardless or your provider, built into your product. Fixed scope from £4,000, PCI compliance included.
Solutions we've built power teams at:
Billing is the least glamorous part of a product and the worst place to cut corners. A missed renewal or a double charge costs real money and real trust — so payment integration is one job you want done right the first time, not patched later.
How you take money decides the provider — Stripe, GoCardless or the one you already use. We recommend on fees and fit, and if your provider's own hosted checkout already covers it, we'll tell you so.
You get a fixed price from £4,000 with PCI compliance in scope, not bolted on — card details go to the provider, not your servers. Subscriptions, invoicing or checkout, whichever you're wiring in.
We build the integration into your product, handle failed payments and retries, and test it end to end before go-live — because a billing bug you find in production is the expensive kind to find.
Need multi-party payouts, VAT and reconciliation? That's a billing platform from £10,000. And if renewals or invoices break later, a scoped fix makes them dependable again — all code and IP yours on payment.
Creator subscriptions running on Stripe Connect, in-app purchases tied to a Shopify store, and a wealth-planning app built on open banking. Billing is the least glamorous part of a product and the worst place to cut corners — so we don't.
Udokk saw growing demand for trustworthy digital health content and had an extensive professional network ready to create it. CodeLeap built the platform where healthcare professionals publish scientific and educational video for practitioners, students and the public, and earn from it.
Read moreCicerone Press is the UK's pre-eminent outdoor guidebook publisher, with a catalogue of over 450 titles and decades of heritage, and its readers increasingly wanted route information on the trail rather than in a book. CodeLeap built the app that carries the catalogue into a map-driven digital experience without losing the depth that makes the guides worth buying.
Read moreWealth management is priced and structured for high-asset clients, and Bonsai Wealth wanted to close that gap with a mobile product giving genuinely personalised advice at scale. CodeLeap designed and built the full platform, covering goal planning, investment management across account types and open banking.
Read morePayments name-by-name — the providers our shipped billing runs on, and the ones we integrate with when they fit how you charge.
Udokk's creator subscriptions run on Stripe Connect — including the multi-party payouts that make marketplace billing hard.
We integrate with GoCardless where Direct Debit fits how you bill — recurring invoices that collect themselves, UK-style.
We've shipped RevenueCat for app-store subscriptions — one source of truth for who's paid, across Apple, Google and Stripe.
Bonsai's wealth-planning app runs on an open banking API integration we built to move cleanly between providers — no lock-in by design.
We've shipped in-app purchases and subscriptions through both app stores — including the review quirks we've already learned the hard way.
Cicerone's app ties in-app purchases to its Shopify customer hub — commerce and app billing reconciled rather than fighting.
Invoicing flows we build post straight into Xero — money movements your accountant can trace without a spreadsheet.
This is what comes up most often, not a limit. Bring us something that isn't on this list and we'll get up to speed on it — working with something new is the job, not an obstacle.
Real reviews from clients we have delivered for, on Clutch and elsewhere.
The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.
They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.
CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.
Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.
CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.
Their flexibility and focus on quality were outstanding.
Marcelo has been wonderful throughout the process and we are very happy.
Absolutely FANTASTIC. This is very much what I had in mind. We're very pleased with your team, thank you all very much.

Stripe, GoCardless or the provider you already use. The right choice depends on how you charge — one-off, subscription, invoicing or marketplace payouts — and we'll recommend based on fees and fit, not habit. And if your provider's own hosted checkout already covers what you need, we'll tell you — not every setup needs an integration project.
A scoped payments integration starts from £4,000 — subscriptions, invoicing or checkout wired into your product. A full billing platform for complex or multi-party payments starts from £10,000. Fixed price, agreed upfront.
Well under our typical three-month project — a scoped checkout or subscription integration is one of the quicker jobs we do. We'll give you a clear timeline upfront and keep you updated at every stage.
Yes — PCI compliance is part of the scope from day one, not a bolt-on. Card details go to the payment provider, not your servers, which keeps your compliance burden small and your customers' data out of harm's way.
Yes. Failed renewals, missing invoices and double charges are exactly what a scoped integration fix addresses — we'll review what's there and quote a fixed price to make it dependable.
A small, experienced team of designers, engineers and problem-solvers working closely with you from first idea to final delivery.
