Devtechify · Tamil Nadu · South India
Software Development Company in Chennai
Websites, custom software, AI agents, WhatsApp automation and billing tools for Chennai businesses, built by Devtechify.
Walk through Ambattur, Guindy or Sriperumbudur and you can see how much of Chennai runs on supply chains. A component maker waits on a dealer's schedule, the dealer waits on stock from the plant, and the service workshop waits on parts. Machinery shops quote by phone and confirm on WhatsApp. Hospitals and diagnostic labs add their own pile of appointments, reports and insurance paperwork, passed between people who are rarely at the same desk.
We would start with whichever of these hurts most, usually a dealer or workshop still matching parts and invoices by hand. No office visit is needed, and the scope stays what we wrote down.
Chennai and the wider Tamil Nadu market
Tamil Nadu doesn't have one economy, it has about six. Chennai's suburbs are an auto and electronics supply chain. Coimbatore makes pumps and motors and sits beside the textile towns of Tiruppur, Erode and Karur. Sivakasi prints and packs for half the country. Madurai sells to temple crowds and to the whole of the south. And then there are the small towns that quietly own one trade: Ambur's footwear, Dindigul's locks, Namakkal's eggs and lorries.

What we build for Chennai's businesses
Auto component makers and dealers
Component makers supply plants on fixed schedules while dealers juggle vehicle stock, service jobs and spare parts, so the real headache is matching what was ordered, delivered and invoiced across several counters.
Parts catalogues and stock tracking, counter and workshop billing, supplier payables, and customer service reminders on WhatsApp.
Read the guideEngineering and machinery firms
Machinery firms in the industrial belts quote custom jobs against drawings and revisions, and the pain is tracking which quote became which order, what is half-built, and what is still unpaid.
Quotation and enquiry management, project-wise billing, purchase orders to suppliers, and a credible company website that wins tenders.
Read the guideClinics, hospitals and diagnostic labs
A clinic or diagnostic lab in a large city runs on slots, reports and repeat visits, and software removes the double entry between the front desk, the lab and the patient's phone.
Appointment booking pages, WhatsApp reminders to cut no-shows, and billing for consultations, tests and pharmacy counters.

Questions from Chennai businesses
Does Devtechify have an office in Chennai?
Our team is based in Bengaluru and works with clients across India remotely. For Chennai projects we run the kickoff, weekly demos and reviews over video calls and WhatsApp, and we can plan an on-site visit when a workshop would genuinely help.
Can you build software for auto components and dealerships in Chennai?
Yes. For this kind of business we typically build: Parts catalogues and stock tracking, counter and workshop billing, supplier payables, and customer service reminders on WhatsApp. Component makers supply plants on fixed schedules while dealers juggle vehicle stock, service jobs and spare parts, so the real headache is matching what was ordered, delivered and invoiced across several counters.
How much does a website or custom software cost for a business in Chennai?
It depends on scope, not on the city. A simple business website is a small project, while custom software with logins, billing or integrations takes longer and costs more. We give a fixed scope and estimate after a short discovery call, and our guide on website and app costs explains what drives the number.
Do you offer WhatsApp automation and billing software for Chennai businesses?
Yes. WA Getway is our WhatsApp platform for messaging, broadcasts, auto-replies and the official Meta Cloud API. Billy is our cloud billing and inventory software for invoices, POS, stock and dues. Both are live, and either can be customised for your business.
How do we get started with a project in Chennai?
Fill in the short form on this page or message us on WhatsApp. We reply within one business day, set up a call, and send a clear plan with scope, timeline and price before any work begins.
