Payments that reconcile at the end of the month.
Checkout, recurring billing, refunds, payouts and webhook handling implemented so finance can trace every transaction without a spreadsheet.
- Stripe & Paddle
- Subscriptions
- Reconciliation
Checkout, subscriptions, payouts and reconciliation wired up securely end to end.
The failure modes are the whole job.
Taking a card payment is simple. Handling duplicate webhooks, failed renewals, partial refunds, disputes and currency rounding is what determines whether your books balance.
Why it matters
Payments are where bugs cost money directly. Idempotency, webhooks, retries and reconciliation matter more than the integration itself.
What we build
Card and wallet checkouts, subscriptions and metered billing, multi-currency and regional providers, marketplace payouts and reconciliation tooling.
Who it is for
SaaS products introducing billing, marketplaces splitting payments, and businesses expanding into new regions or payment methods.
What we handle from strategy to delivery.
Six areas we take responsibility for on payment integration engagements — no handoff gaps between them.
- 01
Payment strategy
Providers, methods and regions matched to your customers.
- 02
Checkout implementation
Hosted fields, wallets, 3D Secure and SCA compliance.
- 03
Subscriptions & metering
Plans, proration, trials, upgrades and usage billing.
- 04
Webhooks & reconciliation
Idempotent handling, retries and ledger-accurate state.
- 05
Failure & dunning flows
Retry schedules, recovery emails and clear customer messaging.
- 06
Compliance & reporting
PCI scope reduction, tax handling and finance-ready exports.
Standards we hold every payment integration project to.
- PCI conscious
- Hosted fields, reduced scope
- Idempotent
- No double charges
- Multi-currency
- Regional methods supported
- Reconciled
- Finance-ready reporting
From first conversation to a product that is ready to grow.
01 — Discover
We review the catalogue, pricing rules, fulfilment and the drop-off points in the current funnel.
We review requirements, existing analytics, competitors and user needs to understand where payment integration will create the most value. Nothing is proposed before the problem is clear.
Deliverables
- Commerce requirements
- Catalogue assessment
- Conversion baseline
Typical activities
- Stakeholder workshop
- Analytics review
- Competitor teardown
Success criteria
A clear, shared understanding of the problem, scope and expected outcome.
02 — Define
We agree the platform approach, data model and integrations before design begins.
We turn research into a clear product direction, priorities and information architecture. Scope, sequencing and technical direction are agreed in writing before work starts.
Deliverables
- Platform decision
- Product data model
- Integration plan
Typical activities
- Technical design
- Migration planning
- Estimation
Success criteria
Everyone understands what is being built, in what order, and why.
03 — Design
We design browsing, product and checkout experiences around conversion on mobile first.
We translate the agreed structure into a polished, responsive interface — every state, breakpoint and edge case included, reviewed together as we go.
Deliverables
- Storefront designs
- Checkout flow
- Merchandising sections
Typical activities
- Flow design
- Visual design
- Review
Success criteria
The experience is validated and ready for implementation.
04 — Build
We implement the storefront, checkout and integrations with stock, payments and fulfilment.
We turn approved designs into production-ready software using maintainable components and a scalable architecture. You see working software throughout, not just at the end.
Deliverables
- Storefront implementation
- Payment integration
- ERP or inventory sync
Typical activities
- Development
- Integration work
- Code review
Success criteria
The product works reliably across the required devices and scenarios.
05 — Validate
We test the full purchase path, including refunds, edge cases and peak-load behaviour.
We test the product against the real requirements, profile performance and surface issues before launch rather than after it.
Deliverables
- Checkout test matrix
- Performance results
- Migration dry run
Typical activities
- Transaction testing
- Load testing
- Redirect verification
Success criteria
Critical issues are resolved and the product is ready for launch.
06 — Launch
We go live with redirects, analytics and a plan for post-launch conversion improvements.
We deploy, review the built product in production and refine the details that only appear in the real thing. Monitoring and handover happen at the same time.
Deliverables
- Live store
- Redirects and analytics
- Optimisation backlog
Typical activities
- Cutover support
- Monitoring
- Conversion iteration
Success criteria
The product is live, verified, documented and ready for users.
Everything handed over, nothing locked away.
Concrete output at the end of a payment integration engagement — code, assets and documentation you own.
The stack we reach for first.
Chosen per project constraints — this is the starting point, not a rule.
