Web applications
Operational systems, portals and dashboards with role-based access, document workflows and real-time views, built for scale from the first release.
At Infynix, we craft growth engines that inspire and endure.
Custom web software engineered in React 19 and Next.js built for your business operations. Off-the-shelf software forces teams into awkward, inefficient workarounds. Custom software should fit how you work, not the other way around.

Custom web and app development for Kerala businesses and startups from Kochi: operational systems, portals, dashboards and products built on React, Next.js and Node.js, with the mobile apps that go with them, the integrations they depend on, and the Indian requirements designed in from the first sprint. For businesses whose process no off-the-shelf tool fits, and for products where the software is the business.
Off-the-shelf software rarely fits a growing Kerala business for long. The hospital group runs bookings in one place and records in another, the developer manages off-plan sales in spreadsheets, the distributor has a godown system that does not know what the website sold, and the startup has an MVP its first developer built that nobody wants to touch. Custom software is how the business gets a system that works the way it actually operates.
We build through a process that starts with how the business works rather than a feature list: discovery with the people who run the process, a specification and a fixed estimate, prototypes reviewed by the people who will use the screens, two-week sprints with a working demo at the end of each, rehearsed migration and on-site go-live.
We work with hospitals, real estate, trading and logistics, education, professional services, e-commerce and startups in Infopark, Technopark and Cyberpark, with engineering capacity from Kochi, the UAE and the UK.

Professional services
Client portals, document workflows, time and billing and compliance records.
How we engage
Fixed-scope project
Discovery produces a specification and a fixed price. Best when the problem is understood and the scope can be agreed before code is written.
Dedicated team
A named team working on your roadmap month to month, with sprint planning and demos. Best for products that keep evolving.
Discovery first
A paid two to three week engagement that produces the specification, architecture and estimate, whether or not we build it.
Support and evolution
SLA-backed maintenance, monitoring and continuous improvement for systems we built or inherited.
How a build runs, week by week
Discovery takes the first two to three weeks: workshops with the people who run the process today, a map of the systems and data involved, a written specification, an architecture and a fixed estimate. Design follows, with clickable prototypes reviewed by the people who will use the screens, because the billing clerk and the store supervisor find the problems a project sponsor never sees.
Build runs in two-week sprints with a working demo at the end of each. Data migration rehearsals start early. User acceptance testing runs on staging with real data. Go-live is planned with a cutover checklist, a rollback path and the team at your premises for the first days. Support starts the day the system goes live.
Weeks 1 to 3
Discovery, specification, architecture and fixed estimate.
Weeks 3 to 5
Prototypes reviewed with the people who will use the system.
Sprints
Two-week cycles with a working demo at the end of each.
Go-live and support
Rehearsed cutover, on-site presence and SLA support from day one.
Rebuilding the MVP without losing the business
Many Kerala startups run on an MVP built fast by a first developer or a small agency, and it has reached the point where every new feature takes longer than the last and nobody wants to touch the payment code. The choice is not rewrite or die. It is a staged rebuild: assess what exists, stabilise what is fragile, extract the parts that are worth keeping behind clean APIs, and replace the rest module by module while the product keeps running.
We do that assessment honestly, and we document the architecture so the in-house team the company will eventually hire can inherit it.
Honest assessment
What to keep, stabilise, extract and replace, in writing.
Staged rebuild
Modules replaced one at a time while the product runs.
Clean APIs
The parts worth keeping wrapped so they can be replaced later.
Documented for the next team
Architecture written for the hires you have not made yet.
GST, DPDP and the Indian requirements
Every system that touches money in India sits inside GST: invoice formats, HSN and SAC codes, place of supply logic and returns that need data by rate and counterparty, with e-invoicing for businesses above the threshold. Every system that holds personal data sits inside the Digital Personal Data Protection Act: consent, purpose, data principal rights and breach notification. Retrofitting either into a live system is slow and risky.
We design for both from discovery, host in Indian cloud regions, integrate with Tally so the accountant keeps their tool, and document the data map so a compliance review finds the reasoning.
GST-compliant documents
Invoices and credit notes with the required fields, and return-ready data.
E-invoice readiness
IRN generation through a GSP where the business needs it.
DPDP workflows
Consent, access and erasure handled from the system.
Indian hosting
AWS Mumbai and Hyderabad, Azure Central India, Google Cloud Mumbai.
Payments, WhatsApp and the Kerala customer
Indian commerce runs on UPI, on cash on delivery, and on a customer who expects a WhatsApp update at every step. UPI intent flows on mobile, gateway choice between Razorpay, PayU, Cashfree and PhonePe, cash on delivery with its return rates, courier integration through Shiprocket or Delhivery, and WhatsApp Business API for every notification: each has edges that a team building for the first time discovers expensively.
We have integrated all of these and know where the edges are. The system reconciles payments and COD properly, records payment method against margin, and pushes updates to the customer over WhatsApp in Malayalam or English.
Gateway integration
Razorpay, PayU, Cashfree, PhonePe and Paytm with UPI, cards and EMI handled.
Cash on delivery
COD orders, courier remittance and returns handled end to end.
WhatsApp Business API
Notifications and conversations logged against the record.
Courier connections
Shiprocket, Delhivery, DTDC and Blue Dart with tracking to the customer.

Custom Web & App Development questions
How long does a typical software project take?
An MVP takes 8 to 12 weeks. A portal or operational system runs 10 to 20 weeks depending on scope and data migration. Enterprise platforms take 4 to 8 months, delivered in releases so value arrives before the final milestone.
Can you rebuild an MVP that has become hard to maintain?
Yes. We assess what exists, stabilise what is fragile, wrap the parts worth keeping in clean APIs and replace the rest module by module while the product keeps running, with the architecture documented for your future team.
Do you build systems that comply with GST and the DPDP Act?
Yes. GST-compliant documents, e-invoicing readiness and DPDP consent and rights workflows are part of the standard data model, with hosting in Indian regions.
Can you integrate with Tally?
Yes. Most builds keep Tally Prime as the ledger and feed it from the operational system, so the accountant works in the tool they know.
Do you work with startups through Kerala Startup Mission?
Yes. We build products for KSUM-backed and Infopark companies that need a senior engineering team without hiring one, on a dedicated team or fixed-scope basis, with the architecture documented so an in-house team can take over.
Do you build in Malayalam?
Yes. Bilingual interfaces with Malayalam typography that renders on a mid-range phone are standard, for staff screens as well as customer-facing ones.
Who owns the code?
You do. Source code, infrastructure, documentation and credentials are handed over in your name, and the system is built so another competent team could run it.
Do you sign NDAs and work with our existing IT team?
Yes to both. NDAs are signed before discovery, and we work alongside in-house IT, the accountant on Tally, hardware vendors and existing developers, documenting the system so any of them can understand where it fits.
How quickly can you start?
Discovery can usually begin within two weeks of agreement, and the first working release is typically live within eight to twelve weeks of discovery ending.
