Home/Services/Custom Software Development

Custom software built around your business

Spreadsheets, disconnected tools and manual steps slow a growing business down. We design and build software that fits the way your team works, from internal tools to complete business systems. One team handles analysis, design, development, testing and support, and you own all of the code.

FAQ

Custom Software Development: common questions

Do I need detailed requirements before contacting you?

No. Most clients start with an idea and a list of problems. Our requirement analysis turns that into a written scope you can review before any development starts.

Can the software connect to tools we already use?

Yes. We regularly integrate accounting software like Tally, Zoho Books and QuickBooks, CRMs, payment gateways, email and WhatsApp, and anything else with an API.

Fixed price or hourly?

Both. When the scope is clear we quote a fixed price with milestones. When requirements are still evolving, a dedicated developer billed monthly works better.

What happens after launch?

You get 30 days of free bug fixes. After that you can choose a monthly maintenance plan or contact us only when you need changes.
