The problem

What this actually looks like day to day

Payment integrations look finished long before they’re safe. The happy path works in a week.

What takes the remaining time is everything else: the timeout that leaves a transaction in an unknown state, the duplicate charge from a retried request, the refund that never reached the ledger, and the month-end when the gateway’s numbers and yours disagree by an amount nobody can explain.

Signs this is you

  • Month-end settlement numbers don't match the gateway's
  • A retried request has ever caused a duplicate charge
  • Refunds sometimes don't make it back to the ledger cleanly
  • Nobody's fully sure what happens when a payment times out mid-transaction
What we do

Fintech Engineering, end to end

Payment gateway integration

UPI, cards, netbanking, wallets.

Subscription & recurring billing

Including mandates and retries.

Reconciliation systems

And settlement reporting.

Ledger design

And financial data modelling.

Idempotency, retry & failure handling

The work that decides whether the integration is actually safe.

PCI-DSS-aware architecture

So scope stays as small as possible.

Fraud & risk controls

Appropriate to your volume.

How we engage

Three ways to work with us

Advisory

We assess what you run today, architect what should replace it, and hand you a roadmap with sequencing and costs. You take it from there, or we build it.

Build

We deliver the work: design, development, integration, migration and rollout, against a scope and price agreed up front.

Run

We stay on to operate and support what we built, with stated response times and a regular review of what to fix or add next.

What you get

Deliverables, not just a plan

  • Integration architecture with failure modes documented
  • Production integration with reconciliation built in from the start
  • Ledger and reporting your finance team can operate
  • Test coverage across the failure paths, not just the happy one
Who it's for

Is this the right fit?

Businesses collecting payments at meaningful volume, platforms handling money on behalf of others, and teams whose existing payment integration has become hard to trust.

Start with an honest look at what you run

Tell us what you're running today and where it hurts. We'll come back with the two or three changes worth making first — and if the answer is that your setup is fine, we'll say that instead.
