Payment integration, built to be relied on.

We design, build and support payment systems for software companies, with the controls, audit trail and failure handling a regulated business expects.

Services

Four ways we help a business take and move money with confidence.

Payment integration

End-to-end integration with card, bank and wallet providers, delivered to a plan you can hold us to.

Discuss an integration
  • Provider selection and cost modelling
  • Parallel integration architecture for faster delivery
  • Comprehensive testing, including failure scenarios
  • Compliance framework design
  • Post-launch monitoring and optimisation
  • Knowledge transfer to your team

Multi-provider and cost optimisation

Systems that route across providers, cost less to run and keep taking payments when one provider doesn't.

Review your set-up
  • Routing logic to reduce cost per transaction
  • Redundant providers for resilience
  • Real-time performance analytics and alerting
  • International payment method support
  • Currency conversion and settlement strategy
  • Infrastructure planned for growth

Legacy modernisation

Remove technical debt from ageing payment systems without interrupting the revenue running through them.

Plan a migration
  • Legacy assessment and modernisation roadmap
  • Zero-downtime migration planning and execution
  • Modern API architecture and security
  • Compliance upgrades for current regulation
  • Team training and knowledge transfer
  • Ongoing architectural guidance

Custom automation

AI-assisted automation for when standard payment tools can't handle your business logic.

Talk about custom work
  • Custom AI development for payment workflows
  • Fraud detection and monitoring
  • Automated compliance and regulatory reporting
  • Business rule engines for complex logic
  • Proposal and documentation automation
  • Integration with your existing payment stack

  • Global operations

    Enterprise systems for major industrial and retail operations with international distribution networks.

Risks we design for

Most teams underestimate payments until they are deep into the build.

  • Failed integrations

    Webhooks fail, transactions go missing and customers can't pay, usually after a launch date was promised.

  • Hidden costs

    Transaction fees, currency conversion, compliance costs and regulations nobody budgeted for.

  • Compliance

    PCI DSS, AML and KYC requirements. One mistake means penalties or a shutdown.

  • Time to market

    Every month without working payments is lost revenue while competitors launch.

  • International complexity

    Different payment methods per country, currency handling, tax and local regulation.

  • Legacy systems

    Old systems weren't built for modern payments. APIs are missing, data conflicts and security is out of date.

How we build

Payments fail in predictable ways. We build for those failures from the first day.

  • Safe retries

    Payment requests are idempotent, so a retry or a double-click never charges a customer twice.

  • Reliable webhooks

    Provider events are verified, retried and logged, so a missed notification doesn't lose a payment.

  • Reconciliation

    Every payment is matched against provider settlement reports, so finance can trust the numbers.

  • Audit trail

    Every change of payment state is recorded with who, what and when.

  • Provider failover

    A second provider can take over when the first is unavailable.

  • Tested failure paths

    Declines, timeouts, partial refunds and chargebacks are exercised before launch, not discovered after it.

How a project runs

The same four stages on every engagement.

  1. Discovery and strategy

    A free consultation to understand your requirements, compare providers and agree a roadmap.

  2. Architecture design

    A payment architecture that covers compliance, security and future growth.

  3. Development and testing

    Agile delivery with continuous testing, including edge cases and failure scenarios.

  4. Deployment and support

    A smooth go-live with monitoring, documentation and ongoing support.
