Questions about web application development
How much does a web application cost?
It depends on the scope: the number of user roles, features, integrations and design work. After a free consultation we send a fixed-scope estimate with clear milestones.
Who owns the code?
You do. On final payment the source code, database and documentation are handed over to you.
Can you take over an existing project?
Yes. We start with a code and security review, then propose a plan to stabilise, improve or rebuild it.
