FAQ
Common questions
How long does a web application take?
Most MVPs ship in 4–8 weeks. Larger platforms with complex integrations typically run three to six months, delivered in two-week sprints so you see progress continuously.
Do we own the source code?
Yes. You retain full ownership of the codebase, repositories and infrastructure accounts. We hand over documentation and walk your team through the architecture at launch.
Can you work with our existing system?
Absolutely. We regularly modernise legacy applications, add APIs to existing platforms and integrate with CRMs, ERPs and payment providers already in use.
What happens after launch?
We offer ongoing maintenance plans covering monitoring, security patching, performance tuning and feature development, with 24/7 support coverage available.
