Common Questions

What clients
always ask

How long does a web application take to build?
A well-scoped web application typically takes 8–16 weeks from design to production launch, depending on complexity and integration requirements.
Can you build a SaaS product from scratch?
Yes. We have built SaaS products from initial concept — architecture, UI/UX design, frontend, backend, billing integration, and cloud deployment.
Do you handle ongoing feature development post-launch?
Yes. Retainer-based ongoing development is available for post-launch feature work, maintenance, and performance optimisation.
