UPI Switch Development

A UPI switch routes and settles every transaction between your systems and NPCI. When it slows down, that shows up as a failed payment, and volume does not wait for a fix. We design the routing, core banking connections, and compliance controls as one system, built for banks, PSPs, and TPAPs who need it to work on their busiest day.

Chances are one of these is true.

Where are you right now?

01Building UPI acceptance

You need to accept UPI payments without one vendor

Renting a switch from a single provider works until your volume or your roadmap outgrows their release schedule. We build a switch you own, so changes and scale sit on your timeline.


A switch that answers to you.

02Modernising an aging switch

Your current switch struggles when volume spikes.

Festival traffic and merchant sale days can multiply your transaction load within minutes, which is exactly where fintech apps struggle with scalability if the architecture was not built for it.


Built for peak load, not average load.

03Preparing for certification

You are getting ready for NPCI certification.

The NPCI certification process for technology service providers runs through a sandbox and testing environment before anything reaches production, and the technical specification is exacting.


Built for certification, not retrofitted

What we build for the switch.

UPI switch infrastructure, built as one system

We build the routing engine, the core banking connections, the compliance controls, and the ongoing monitoring as one system, not separate vendor pieces stitched together. Each part is designed for the load and audits a real switch has to survive.

Switch architecture & routing

Message routing that distributes load so one spike does not slow every channel.

Message routingTransaction switchingLoad distributionReal-time processing

The routing engine reads every transaction and sends it to the right bank, PSP, or TPAP, applying the same principles that keep real-time transactions without delays across any payment stack. We design it to distribute load across servers, so a spike in one channel does not slow down every channel.

Core banking & PSP integration

Connections between systems that were never built to talk to each other.

Core banking connectionsPSP and TPAP linkageAccount and ledger mappingLegacy system connections

Your switch has to talk to core banking systems, PSPs, and TPAPs that were not built with each other in mind. We build the connections that let transactions move between them without manual reconciliation.

Compliance & certification

Encryption, data localisation, and audit trails built in from day one.

Encryption and data controlsData storage within IndiaAudit trail designNPCI certification support

NPCI certification testing expects specific technical standards, from encryption to data storage within India. We design the switch to meet those requirements from the first architecture decision, not as a late addition.

Monitoring & modernisation

Real-time visibility, plus staged migration for an aging switch.

Real-time monitoringHorizontal scalingLegacy switch migrationOngoing support

We build monitoring into the switch so failed and delayed transactions are visible immediately, not after a customer complains. For an aging switch, we migrate it in stages so your existing volume keeps moving while we modernise underneath it.

Why banks & PSPs pick us.

A team that ships UPI switch infrastructure

Payment infrastructure, not just apps

Building a UPI switch differs from a checkout flow, and we treat it that way. Our engineers design for routing, settlement, and certification from day one.

We build for the audit, not around it

NPCI certification is not an afterthought in how we design a switch. Encryption and audit trails are part of the architecture from day one.

Senior engineers from the first call

You work with engineers from our fintech team in Bangalore who have built payment infrastructure before, not a team learning UPI on your project.

Modernise without losing what works

If you have an existing UPI switch, we migrate it in stages, so live transactions keep moving while we rebuild underneath it.

How we build it

Senior engineers from day one, with real NPCI certification experience behind them. Our UPI switch development pairs you with people who have built payment infrastructure before, not an account manager relaying notes.

UPI switch development, in plain terms

A UPI switch is the routing and settlement layer that connects your systems to NPCI's UPI network, moving transactions between banks, PSPs, and TPAPs. Any bank, NBFC, or fintech handling UPI volume needs one, whether built in-house or run through a technology service provider.

Yes. We design the switch to meet NPCI's technical specifications for TSP empanelment from the start, including the sandbox and testing stages, so NPCI certification is a checkpoint rather than a rebuild.

Yes. Much of our work is modernisation: migrating routing and settlement logic in stages so your live transaction volume keeps moving while we rebuild the parts that need it.

Cost depends on your existing infrastructure, your transaction volume, and how much of the switch needs to be built versus modernised. We scope this after a short discovery and agree the cost and timeline before any build work starts.

We design the routing layer to distribute load across servers and scale horizontally, addressing the same root causes behind payment failures in fintech applications during peak load. This is tested against burst conditions before launch, not assumed.
