Custom Software Development
Software Built Around How Your Business Works.
DVM Techno is a custom software development company based in Gurgaon, Haryana. We design and build web applications, SaaS platforms, billing and inventory systems, booking tools and workflow automation for businesses across Haryana and India — software that fits your exact processes instead of forcing you to change them.
Off-the-shelf software is built for everyone, so it rarely fits anyone perfectly. Custom software gives you exactly the modules, reports and user roles you need, integrates with the tools you already use — from Razorpay and WhatsApp to Tally and government portals — and grows with your business.
Every project starts with a clear SRS document and a fixed-price quote, and ends with 100% source code ownership for you. Need an app too? Our mobile app team can build it on the same backend.

FAQs
Custom Software FAQs.
Everything you need to know before building custom software.
How much does custom software development cost?
It depends on the number of modules, users, integrations and whether you need a mobile app. After understanding your requirements we prepare a detailed SRS with module-wise cost and timeline, on a fixed-price contract.
How is custom software different from off-the-shelf software?
Off-the-shelf software is built for everyone — so it rarely fits perfectly. Custom software is built for your exact workflows, team size, and business rules. No unnecessary features, no missing ones.
Do I own the source code?
Yes. All custom software developed by DVM Techno — the full source code — is transferred to you upon project completion and final payment.
Can you build a SaaS product from scratch?
Yes. We specialise in SaaS development — multi-tenant architecture, subscription billing (Razorpay Subscriptions/Stripe), onboarding flows, and admin dashboards.
What technology stack do you use?
We choose based on your requirements: React.js/Next.js for frontend, Node.js/Python for backend, PostgreSQL/MongoDB for database, AWS/GCP for cloud. We're flexible — not tied to one stack.
Can you modernise or migrate our legacy software?
Yes. We handle legacy system modernisation — migrating from outdated desktop software to cloud-based systems, rewriting codebases, and integrating with modern APIs.
Do you provide post-launch support?
Yes. All packages include post-launch support (bug fixes, minor changes). Ongoing maintenance contracts are available for software that needs regular updates.
Can you integrate government portals like GST, e-invoice?
Yes. We have experience integrating GST portal, e-invoice, e-way bill, DigiLocker, Aadhaar eKYC, NSDL, and GSTIN verification APIs.
