FAQ
Questions buyers ask us
How much does custom software or an e-commerce website cost?
It depends on the features, number of users, integrations (payments, shipping, Tally, marketplaces) and whether you need a mobile app. Instead of a vague range, we send a written, itemised estimate within 24 hours of receiving your requirement, so you can decide what goes into the first release.
How long does it take to build an online store or a web application?
A Shopify or WooCommerce store usually takes 3–6 weeks. A custom web application or dealer portal typically takes 8–14 weeks, delivered in phases so your team starts using it early.
Do I own the source code?
Yes. The source code, designs, domain and cloud accounts belong to you. You can keep us for support or hand everything to another team at any time.
Can you take over software that another developer built?
Yes. We audit the code and hosting, document what we find, fix urgent issues first and then continue with regular maintenance and support.
Do you work with clients outside Chennai and outside India?
Yes. We are based in Otteri, Chennai and work with clients across India and abroad over video calls, WhatsApp and shared project boards. Chennai clients can also meet us in person.
What happens after launch?
The same team that built your software stays on to support it: bug fixes, security updates, backups, monitoring and new features under a monthly plan. You are never left with software nobody understands.
