FAQ
Common questions.
Quick answers on pricing, timelines, ownership and support.
Still have questions?Talk to our team. We reply within one business day.
01How much does custom software development cost in Sri Lanka?
It depends on scope, features and integrations. After a short discovery call we send a fixed-scope quotation, so you know the price before any work starts.
02How long does a typical project take?
A marketing website usually takes a few weeks, while web platforms and mobile apps take a few months. We agree milestones up front and share a working demo every week.
03Do we own the source code?
Yes. You own the source code and receive full documentation at handover.
04Do you offer support after launch?
Yes. Our maintenance plans cover updates, fixes, hosting, backups and new features.
05Do you work with clients outside Colombo or overseas?
Yes. We are based in Homagama and work with clients across Sri Lanka and internationally, meeting in person or online with regular demos and clear milestones.
06Should I buy a ready-made product or a custom build?
If your needs fit a POS, LMS, car rental, HR or hotel booking system, a ready-made product gets you live in weeks and can still be customised. For unique workflows, a custom build is the better fit. We will advise honestly on a free consultation.
