FAQ

Frequently asked questions

How much does a website or software project cost?

It depends on the feature scope and complexity. After a free discovery session we send a detailed, itemised quote so you can decide with confidence.

How long does a project take?

A corporate website usually takes 2–4 weeks; business software or mobile apps take 1–4 months depending on scope. The timeline is agreed up front.

Do I own the source code?

Yes. On acceptance you receive the full source code, technical documentation and administrative access.

Do you provide support after launch?

Every project includes a warranty period, and we offer ongoing maintenance plans if you need a long-term partner.
