Overview

Transaction & settlement infrastructure for public sector, built to the standard institutions in this sector are required to operate.

XVICA designs, builds, and operates this layer for public sector clients in the UK, US, Canada, and Australia. The work is specified against the regulatory regime, the operational profile, and the examination expectations of this sector before any code is written.

01Why it matters

What public sector cannot get wrong here.

A late benefits payment is not a customer complaint; it is a Select Committee question.
Volume spikes follow policy decisions, not forecasts.
Error rates are published by the National Audit Office.
Every payment decision must be explainable in public, months after it was made.

02Regulatory posture

Named regimes, mapped controls

Regulatory requirements are translated into explicit control requirements, then mapped to tests and evidence collection. Nothing is implied.

UK government frameworks

Service Standard, Technology Code of Practice, Secure by Design, Managing Public Money, Cabinet Office spend controls, and the NAO's value-for-money framework.

Financial control

Consolidated Budgeting Guidance, departmental Accounting Officer responsibilities, and fraud and error measurement under HMT guidance.

Security assurance

OFFICIAL and OFFICIAL-SENSITIVE handling by default; classified environments on a case-by-case basis with accredited infrastructure and vetted personnel.

03Reference architecture

Design decisions distinctive to this intersection

Components and design choices that recur across our work for this sector. Each deployment is specified individually.

Claim-to-payment traceability

Every payment links to the claim, the decision, the rule applied, and the decision-maker. Queryable months or years later.

Dual-rail disbursement

Bacs, Faster Payments, and cheque-print fallback in one platform. No single rail failure interrupts a scheduled run.

Recovery and overpayment

Overpayment lifecycle is a first-class part of the ledger, not a separate spreadsheet process.

Service Standard alignment

Accessibility, user research, and service assessment evidence produced as deliverables, not retrofitted.

Open data where appropriate

Aggregate payment statistics exposed through documented APIs for transparency and analytical reuse.

04XVICA's approach

How we work in public sector.

Public-sector transaction work is governed by a standard private-sector engagements rarely apply: every decision must be explainable, in public, years after it was made. We build with that expectation as a first-class requirement rather than an afterthought. Decision rules are authored in a form that a policy official and an engineer can both read; every payment carries the full decision context with it; every correction is recorded against the original rather than overwriting it. The service passes its assessment not because it was optimised for the assessment, but because the way it was built is the way the assessment expects services to be built. That also means it survives the audit, the NAO review, and the freedom-of-information request that the next administration might raise.
