Payment Infrastructure Engineering

Payment infrastructure built for
your operation, not a template.

We build payment switches, mandate engines, risk systems, and reconciliation platforms — designed around how your institution actually operates, not how a generic product assumes it does.

UPI Switches Mandate Systems Risk Engines Reconciliation Payout Orchestration Compliance

Why generic platforms fall short.

The gaps that show up
after you go live.

Banks and fintechs discover that off-the-shelf payment infrastructure doesn't account for the operational complexity of regulated financial businesses.

01

A payment doesn't end when it's submitted

It needs routing, state tracking, reversal handling, settlement, and a full dispute trail. Most integrations handle the happy path. The edge cases are what break operations at 2am.

02

Your approval flows aren't what the platform assumed

Banks have maker-checker requirements, internal signing hierarchies, and controls that no off-the-shelf product was built for. You end up working around the tool rather than with it.

03

Five banks, three providers, two ledgers — each behaves differently

Every integration has its own protocol, timeout behaviour, and failure mode. Without a proper orchestration layer, that inconsistency spreads through your product and your operations team.

04

Audit trails aren't something you can retrofit

When regulators ask for transaction records or a reconciliation breaks at month-end, the answer depends on decisions made at design time — not something you can bolt on later.

What we build.

The custom layer financial
products are built on.

Switching and orchestration technology for authorized payment participants — managing routing, lifecycle states, integrations, reversals, disputes, and operational monitoring.

  • Bulk and scheduled payouts
  • Duplicate-payment prevention
  • Ledger and reconciliation integration

Configurable verification systems for individuals, businesses, documents, and bank accounts — incorporated into onboarding, transaction, and risk workflows.

  • Customer and business verification
  • Bank-account and UPI validation
  • Document extraction and validation
  • Provider orchestration
  • Duplicate detection
  • Verification audit trails

Risk engines that evaluate transactions, users, beneficiaries, devices, and behavioural signals against configurable business and compliance policies.

  • Configurable rules engine
  • Real-time risk scoring
  • Amount and velocity controls
  • Behavioural and beneficiary checks
  • Allow, hold, review, or decline
  • Case management and audit history

Reconciliation and operations platforms that match records across banks, payment networks, internal systems, and ledgers while helping teams investigate exceptions.

  • Multi-source data ingestion
  • Configurable matching rules
  • Settlement and fee reconciliation
  • Exception and dispute workflows
  • Finance and operations reports
  • Complete action histories

How we work.

Discovery to production —
without the shortcuts.

01

Map the operation first

We start with how your business actually runs — transaction flows, partner relationships, approval processes, risk policies, accounting requirements, regulatory obligations. Architecture comes after we understand what we're building for.

  • Requirement and workflow mapping
  • Existing-system assessment
  • Integration inventory
  • Risk and control requirements
  • Recommended architecture
  • Delivery roadmap
02

Build with the full picture

We convert operational requirements into systems with clear boundaries, configurable rules, and failure handling that's part of the design — not an afterthought. Delivery runs in focused cycles with regular reviews.

  • Clear system boundaries
  • Configurable business rules
  • Secure integrations
  • Transaction integrity
  • Failure and recovery handling
  • Observability and auditability
03

Test every path, not just the happy one

We connect to your banks, providers, networks, and ledgers — then run each critical flow through success, timeout, reversal, and exception scenarios before anything touches production.

  • Integration testing
  • Transaction simulation
  • Failure-path validation
  • Performance testing
  • Security testing
  • Production-readiness support
04

Ship, stabilize, then improve

We stay through go-live, production stabilization, and the first wave of real-world edge cases. The same team that built it handles the optimization, scaling, and continued development.

  • Production stabilization
  • Performance monitoring
  • Incident investigation
  • Optimization and scaling
  • Continued feature development
  • Long-term engineering support

Integration engineering.

Connect complex financial
ecosystems with confidence.

We develop the integration layer between your financial product and the banks, networks, verification providers, ledgers, and operational systems it depends on.

  • Standardized interfaces across providers
  • Secure authentication and access controls
  • Idempotent request processing and retry handling
  • Complete request and response audit trails
  • Real-time monitoring and operational alerts

Engineering foundations.

Designed for financial-grade
operations.

We design security, resilience, data protection, operational controls, and auditability into the system architecture — aligned with the client's applicable policies, partner requirements, and regulatory obligations.

Systems can be designed to support applicable security and compliance requirements, including client-defined controls and standards.

Why Vrikalytics.

We know the domain,
not just the APIs.

We've been inside these systems, not just the docs

UPI switches, mandate processing engines, payout platforms, reconciliation systems — we've built them. We don't spend your project budget learning the domain.

Built around how you run, not how the software assumes

Approval hierarchies, routing policies, partner controls, accounting integrations — we design around your actual operation, not a generic workflow someone else configured.

You own it. Fully.

Deployed in your environment, integrated with your partners, built on your stack. No platform dependency, no usage fees, no SLA tied to our uptime.

We design for the failure at 2am, not the demo

Partial settlements, duplicate payments, bank timeouts, reversal edge cases — we build recovery paths, operational alerts, and team tooling for what actually goes wrong in production.

The same team stays through production

We don't hand off after delivery. The engineers who designed the system handle stabilization, performance work, and continued feature development.

We know how these integrations actually behave

Different banks, different protocols, different quirks in production. We know the integration surface from signed contracts to the edge cases that only show up at volume.

No. Vrikalytics is a technology design and software-development partner. We build payment and financial infrastructure for clients that operate through their own authorized banking, network, and ecosystem relationships.

We work with banks, fintech companies, NBFCs, lenders, insurers, wealth platforms, payment companies, and other businesses developing financial products or modernizing financial infrastructure.

Yes. We can design the orchestration and integration layer around your approved banks, payment providers, verification partners, and internal platforms.

Our core strength is custom financial-technology development. Where appropriate, reusable engineering components and architectural patterns can accelerate delivery without limiting the client's control or requirements.

Yes. We can assess legacy platforms, identify operational and technical risks, and modernize individual components or progressively replace the complete system.

Yes. We can operate as an embedded specialist team, own a defined system or module, or manage the complete engineering lifecycle.

Security and applicable compliance requirements are considered during discovery and architecture, then carried through development, testing, deployment, and operational design. Regulatory responsibility and final compliance validation remain with the relevant authorized or regulated entity.

We can provide technical support for integration testing, transaction simulation, documentation, issue resolution, and production-readiness activities required by the client's banking or ecosystem partners.

Yes. Engagements can include production stabilization, monitoring, incident investigation, performance optimization, maintenance, and continued feature development.
