Payments that cannot fail, regulators who want evidence, and systems that are hard to change safely.
Financial services and payments.Lenders, payment firms, insurers and wealth businesses that need payments built, providers integrated, regulators satisfied and cloud bills governed, by a team that built and ran these systems inside FCA-regulated payment businesses before Hexploits.
Problems we solve here
The ones we hear most often from this sector. Each opens the page with the detail and the case studies.
Core payments: Faster Payments, BACS and SEPA
Ledgers, scheme connectivity, initiation, returns and reconciliation for the UK and EU rails, whether you hold scheme access yourself or reach it through a sponsor bank. Built so a retried instruction never pays twice and every posting can be replayed for an auditor.
Payment and compliance integrations
Stripe, Adyen, GoCardless and the KYC, KYB, sanctions and transaction-monitoring providers your compliance team has chosen, integrated behind one abstraction so switching provider is configuration, and reconciled automatically down to the fee and the chargeback.
Consumer Duty and FCA evidence
Systems that record how customers are treated, how products perform for different groups, how vulnerable customers are supported and how important business services behave under stress, so the board report and the regulator’s questions are answered from data rather than assembled by hand.
AI in payments, credit and fraud under the EU AI Act
Credit scoring and insurance pricing are high-risk uses under the Act; fraud detection is not, but still faces model risk review. Models built with the classification, documentation, logging, oversight and bias testing in place from the first release.
Payment gateways, routing and optimisation
Routing each transaction to the acquirer and method most likely to succeed at the lowest cost, retrying declines where the rules allow, keeping stored credentials current with network tokens, and reconciling every gateway in one place. Built, or bought and integrated, with the business case measured first.
Cloud, cost and governance
Cloud estates that satisfy FCA and PRA outsourcing and resilience rules and DORA where it applies: outsourcing register, tested exit plans, residency by policy, access governed as code, and cost governed so the environments added for every audit come back down.
Reconciliation and reporting that finish in a spreadsheet
Month-end reconciliation, the compliance register, the breaches log and the board pack often finish in Excel because the systems do not talk to each other. Turned into systems with the controls an auditor accepts, one process at a time, with the spreadsheet kept until the numbers agree.
