Payments & Ledger Engineering
Double-entry ledgers, idempotent payment paths, settlement and refunds — built so a retry is safe and every balance is explainable.
Explore paymentsPayment, ledger and onboarding systems that move fast in production and still reconcile to the penny at the end of the day.
In payments, an outage is embarrassing and a rounding error is existential. We build ledgers that are immutable and idempotent, so a retried request cannot double-charge and a reconciliation break has one obvious cause.
Around that sits the unglamorous work that decides whether you pass an audit: KYC and AML integrations, permissioned access, retained evidence, and reporting that regulators can follow without a walkthrough.
Five pressures show up in nearly every financial roadmap we are handed. Here is how we take them off your plate.
Get A Payments AssessmentAn append-only ledger with idempotency keys and a single source of truth, so every discrepancy has one traceable cause.
KYC, AML, PCI and reporting obligations mapped at design time and expressed as tests, not retrofitted before launch.
Risk-based verification flows that keep friction proportional, so low-risk applicants are not treated like high-risk ones.
Scoring with tunable thresholds and a review queue your analysts can actually work, instead of a blunt binary decline.
Incremental strangler migrations behind a stable interface, so the core can be modernised without a freeze on the roadmap.
Five practices covering the money path, the identity around it, and the evidence trail that keeps regulators satisfied.
Double-entry ledgers, idempotent payment paths, settlement and refunds — built so a retry is safe and every balance is explainable.
Explore paymentsIdentity verification, sanctions and PEP screening and risk-based flows integrated with providers, with the decision trail retained for review.
Explore onboardingReal-time scoring, rules your risk team can tune without a deploy, and an analyst queue that shows why a transaction was flagged.
Explore riskCard networks, banking cores, open-banking APIs and accounting systems connected with retries, backpressure and reconciliations that hold.
Explore integrationReporting pipelines and immutable evidence stores, so an audit request is a query rather than a fortnight of manual extraction.
Explore reportingEight problem areas we build against most often for payment, banking and lending teams.
From the first identity check to the last regulatory export — each stage narrows the gap between a transaction and the evidence for it.
Risk-based verification with the decision trail retained for review.
Append-only, idempotent, and explainable down to a single entry.
Timeouts, duplicates and partial failures handled as normal conditions.
Thresholds and rules changed without waiting for a release.
Audit and regulatory extracts produced as a query, not a project.
From concept to completion.
