One defined problem. A working, tested integration.

Payments, identity, messaging, logistics and accounting APIs connected properly — with validation, retries, webhooks and the failure paths most integrations forget.

Book a call What’s included

Is this what you need?

  • Payments that succeed but orders don’t update
  • Webhooks silently failing
  • Duplicate charges or records
  • An integration nobody understands

Typical timeline: 1–4 weeks per integration. We confirm scope, timing and payment milestones in your proposal.

What’s included

Included

  • Review of your code, access and API docs
  • Endpoints, validation and idempotency
  • Webhook handling with signature checks
  • Retries, logging and alerting
  • Tests for success and failure scenarios
  • Deployment notes and handover

Not included

  • Provider fees and account approvals
  • Unrelated refactoring
  • Additional integrations not in scope
  • Compliance certification

Anything outside the agreed scope is quoted separately before work starts — no surprise invoices.

Six steps. No black boxes.

Straight answers.

Can you work inside our existing codebase?

Yes. We review it first and follow your conventions, tests and deployment process.

How do you prevent double charges?

Idempotency keys, verified webhooks and reconciliation checks are part of every payment integration we build.

Do you offer fixed scopes?

Yes — a single, clearly defined integration is quoted as a fixed piece of work.
