FAQ

Questions, answered

What is custom software development?

Custom software is built specifically for your business and workflows, rather than bought off the shelf. It fits exactly how you operate, integrates with your existing tools, and belongs entirely to you. It's the right choice when packaged products force you to change how you work or can't do what you need.

Custom software vs off-the-shelf — which is cheaper?

Off-the-shelf is cheaper upfront; custom software is often cheaper over time once you factor in per-seat licences, workarounds, and the cost of not fitting your process. If a product covers 80%+ of your needs, buy it. If it forces major compromises, custom usually wins. We'll tell you honestly which applies.

How much does custom software cost in India?

A focused internal tool runs ₹3–8 lakh, a multi-module business system ₹8–20 lakh, and enterprise-scale platforms ₹20 lakh to 1 crore+. Cost depends on modules, user roles, integrations, and compliance needs. Our cost calculator gives a quick estimate.

Do you provide support after launch?

Yes. We offer maintenance and enhancement plans, and many clients keep us on for ongoing engineering. But you own the full source code and documentation, so you're free to take it in-house or elsewhere at any time.
