App Development Company in Kolkata

Your app development partner in Kolkata

Kolkata's business families were trading internationally before most Indian cities had electricity. Tea auction houses, jute exporters, the engineering firms across Howrah — plenty still run on relationships and ledgers that have worked for a century. Now their buyers want portals, their auditors want digital records, and the next generation wants systems instead of registers. Moving a firm like that online without breaking what already works is delicate work. It's work we happen to like.

Then there's the other Kolkata: Sector V and Rajarhat, where IT campuses sit beside product startups, fintechs and health-tech teams that need engineering muscle without Bangalore salaries. GTS has run dedicated offshore teams since 2010 — 250+ apps, 100+ clients, ISO 9001:2015 — and for a Kolkata company we're the easy version of offshore. Same country, same time zone, contracts under Indian law, GST invoices, and a team you can actually fly out to meet.

We build from Jodhpur, Rajasthan, and we're upfront about that. What Kolkata clients get is the model our USA and Australia clients pay for — senior architects, code review, documented QA — from about ₹1,600 an hour. Daily standups on video, shared boards, working software every sprint. No overnight ticket queues, no currency risk, no vendor twelve time zones away pretending to be local.

Trading and commodity platforms
Contract, lot and dispatch systems for tea and jute houses — tracking from auction to shipment, with export documentation generated instead of typed.
Hospital and clinic software
Appointment, OPD and patient-record apps for Kolkata's private hospitals and diagnostic chains, built with sensible access controls from day one.
Lending and fintech apps
NBFC lending journeys, collections tools and payment products — KYC, credit bureau and gateway integrations included, audit trail intact.
Manufacturing and ERP tools
Production tracking, quotation and dispatch systems for engineering units across Howrah and the industrial belts — designed to replace the register, not fight it.

Same time zone, live collaboration
Standups, demos and urgent fixes happen inside your working day. Nothing waits overnight.
We handle legacy gracefully
A century-old trading house and a two-year-old fintech need different bedside manners. Since 2010 we've served both, sometimes in the same week.
ISO 9001:2015 discipline
Documented requirements, code review and traceable testing — the paperwork your auditors and your overseas buyers increasingly ask to see.
You own everything
NDA before we hear the idea, full IP assignment and source-code handover after. No hostage code, ever.

How We Work With You

Start small, prove it
Many Kolkata clients begin with one module or a two-week paid discovery, and commit to more only after the first delivery lands.
Dedicated teams or fixed scope
A pod that runs for years, or a project with a hard number attached — both are normal for us.
Weekly demos, written updates
You see working software every sprint and get a written status note every week. Progress you can verify, not progress you're told about.
We'll come to Kolkata
Kickoffs, UAT weeks and go-lives can happen at your office. The day-to-day runs perfectly well on video and shared boards.

Frequently Asked Questions

Do you have an office in Kolkata?

No — we build from our Jodhpur, Rajasthan studio and serve Kolkata clients remotely in the same time zone, with in-person visits for kickoffs and major milestones when the project calls for it.

Can you digitize a traditional trading business without disrupting it?

Yes, and gently. We usually mirror the existing ledger flow in software first, run both in parallel for a cycle, then retire the paper once your team trusts the system. Tea and jute houses carry decades of process worth keeping.

How do your rates compare to Sector V agencies?

Rates start around ₹1,600 (USD 20) an hour — typically under metro agency pricing — and the same team also delivers for USA and Australia clients, so the standard doesn't drop with the price.

Do you build healthcare software?

Regularly. Appointment and OPD systems, patient apps and lab-report delivery, with role-based access and audit logging designed in from the start rather than patched on after.

How do we stay in control of a remote project?

Short sprints, shared boards, staging builds you can install, weekly written reports and code in a repository you can access. If something drifts, you see it within days, not at delivery.
