Comprehensive verification, communication, and automation services for Indian businesses.
Rewrite, refactor, and rearchitect — without disrupting your business.
At KUPIS Fintech Private Limited, we help Indian businesses modernise their legacy applications without disrupting existing operations or making unnecessary investments.
Instead of completely replacing your existing systems, we follow a practical and low-risk modernisation approach. We gradually break down complex monolithic applications, improve them in phases, and migrate suitable workloads to the cloud wherever it adds value.
Our team implements carefully planned changes within live production environments, with minimal business disruption. This enables you to reduce technology costs, improve system performance, introduce new features faster, and preserve the business logic your organisation has built over the years.
Modernise step by step. Reduce costs. Protect your business operations.
Talk to Our Modernization TeamMost legacy systems still work. The cost shows up elsewhere — in speed, risk, and everything you cannot change.
Tightly coupled code means every minor feature request turns into a long release cycle with wide regression risk.
Oversized servers running underused applications, ageing licences, and hardware kept alive purely to host one system.
Frameworks, runtimes, and database versions past end-of-life, no longer receiving security patches.
Critical business rules live only in undocumented code and in the memory of one or two long-serving staff.
Deployments done by hand at night, with no automated testing and no reliable way to roll back a bad change.
No clean APIs, so every new partner, payment provider, or mobile app needs custom glue built from scratch.
Engage us for a single assessment or a full multi-phase programme.
We review your codebase, data model, infrastructure, and release process, then report what to modernise, in what order, and what each step is worth.
Restructuring existing code for readability, testability, and maintainability — without altering the behaviour your business depends on.
Separating a monolith into independently deployable services along real business boundaries, so teams can release without coordinating everything.
Schema cleanup, index and query optimisation, version upgrades, and migration of historical data with full integrity checks.
Wrapping legacy functionality in documented REST APIs so mobile apps, partners, and new services can integrate without touching the old core.
Containerising applications and moving suitable workloads to cloud or managed hosting — only where it genuinely reduces cost or effort.
Repeatable, scripted deployments with automated checks and a tested rollback path, replacing manual release nights.
Replacing dated desktop and server-rendered screens with responsive web interfaces that work properly on phones and tablets.
Recovering undocumented business rules into written specifications, so critical knowledge no longer depends on individual staff.
A single system usually needs a different route for each of its parts. We pick per component, based on business value and risk.
Move the application to better infrastructure with little or no code change. Fastest way to cut hosting costs and retire ageing hardware.
Upgrade the runtime, database, or hosting model — containerising and updating dependencies while behaviour stays the same.
Restructure the code itself: break up oversized modules, remove duplication, add tests, and make the system safe to change again.
Rewrite a specific component on a modern stack — applied selectively, never as a big-bang replacement of the whole system.
We deliberately avoid full-system rewrites. They take longer than planned, carry the highest risk of losing hard-won business logic, and deliver nothing until the very end.
Each phase ends with something running in production — not a document promising future value.
We map how the system is actually built and used today — code, data, integrations, deployment, and the business rules buried inside it.
A prioritised, phase-by-phase plan: what changes first, what it costs, what it returns, and what stays untouched for now.
Before changing behaviour, we add automated tests, monitoring, and a verified rollback path, so every later step can be undone safely.
Old and new run side by side. Traffic shifts to modernised components gradually, and can be shifted back the moment anything looks wrong.
Each phase is checked against the original system's behaviour — same inputs, same outputs — before the legacy path is retired.
Documentation, runbooks, and walkthroughs for your team, with ongoing support available for as long as you need it.
Modernisation is only worth doing if it changes something measurable. We agree the targets with you up front and report against them at each phase.
The stack we build and run production systems on every day.
Working on a stack not listed here? Tell us what you run — assessment and planning work is largely technology-independent.
That is what the phased approach is designed to prevent. Changes go out incrementally with old and new paths running together, so there is no cut-over weekend. Where a brief window is genuinely unavoidable, it is planned with you well in advance.
No. Most engagements start with one high-value area — the part that breaks most often or blocks new features. Later phases are entirely your decision, based on what the first one delivered.
It is preserved deliberately. Those rules represent years of hard-won operational knowledge, so we document and re-verify them rather than reinventing them from a fresh specification.
Only where it pays for itself. Some workloads are cheaper and simpler on existing servers. We migrate what benefits and leave the rest, rather than treating cloud as the goal in itself.
It is a common starting point. Discovery is built to work directly from the running system and its code, so we can proceed without the people who originally wrote it.
With an assessment. It is a defined, self-contained piece of work that leaves you with a written roadmap and cost picture — useful even if you take the next phase elsewhere or defer it.
Programmatic access to India's government identity and business verification infrastructure.
Our verification APIs provide real-time validation of individual and business identities using official government data sources. Integrate our REST APIs into your onboarding flow, KYC process, or verification workflow in hours — not weeks.
Verify customer identity using India's Aadhaar identification system.
Our Aadhaar verification service allows businesses to confirm individual identity against UIDAI data. Use it for customer onboarding, employee verification, or any process requiring confirmed identity.
Instantly verify Permanent Account Numbers against official Income Tax department data.
PAN verification is essential for financial services, lending, and any business requiring tax identity confirmation. Our API provides instant PAN validation with name matching for accurate KYC workflows.
Verify business registrations and GST compliance status instantly.
Before onboarding a vendor, partner, or business client, verify their GST registration against the official GSTN database. Ensure you're working with legitimate, tax-compliant businesses.
Verify any GSTIN in real-time. Confirm business legitimacy before transactions, partnerships, or vendor onboarding.
Verify bank account ownership before disbursements, payouts, or collections.
Bank account verification (Penny Drop / Account Name Match) ensures that the account number and IFSC belong to the correct account holder before transferring funds. Eliminate failed transfers and fraud risk.
Connect with your customers on India's most-used messaging platform.
We help businesses set up and integrate WhatsApp Business API for transactional messaging, customer support, order updates, alerts, and more. WhatsApp reaches customers where they already are.
