The payments problems software finally fixes

Every industry has its own gravity well of pain. Here is where payments teams typically lose the most time, money and trust — and where we focus first.

01

Patchwork integrations

Stripe + Razorpay + ACH + UPI + crypto, each with their own webhook quirks.

02

Auth-rate erosion

Single-PSP routing leaks 5-10% of revenue you never see.

03

Fraud / chargebacks

Every false positive is a lost customer; every false negative is real money.

04

Reconciliation pain

Settlement files, FX timing and refunds make month-end a nightmare.

Capabilities purpose-built for your domain

Six things teams typically ask us to build first — each shipped to production, not demo, quality.

Payment Gateways

Hosted, drop-in and API-first gateways with 3DS2, tokenisation and SCA flows.

Payment Orchestration

Smart routing, retries, fail-over and least-cost selection across PSPs.

PSP & Issuing Back-Office

Merchant onboarding, card issuing, BIN sponsorship and program management.

Reconciliation & Settlement

Multi-source matching, breaks workflow, chargebacks and merchant payouts.

Fraud & Risk

Rules + ML scoring, device fingerprinting, velocity, 3DS challenge orchestration.

UPI / ACH / SEPA

UPI flows, ACH/RTP, SEPA Instant and SWIFT/wire integrations.

How we deliver in payments

Payments tech is unforgiving — every failed authorisation has a customer-support call attached, and every reconciliation break compounds.

Our designs centre PCI DSS, idempotency, observability and the fraud / reconciliation tooling needed to operate in the real world.

01

Threat model

PCI DSS scope, key handling and data-flow mapping first.

02

Architecture

Idempotency keys, exactly-once accounting, observable everything.

03

Build

Auth → capture → settle → refund → reconcile vertical slice.

04

Certification

PCI DSS scan / pen test / RoC support and PSP certification.

05

Operate

24×7 SOC, runbook on-call, monthly auth-rate and recon reviews.

Payments software — questions teams ask us

Yes — segmented CDE, tokenised PAN, HSM key custody, audit-trailed access and SAQ-D / RoC-ready posture is our baseline for payments work.
