Questions
Questions about custom development
How much does custom software cost?
It depends on what the software needs to do. After understanding your requirement we give a written estimate; starting with a small first phase keeps the cost in your control.
How long does it take?
A focused tool can be ready in a few weeks. Larger systems are built in phases, with working parts delivered along the way.
Who owns the software and the data?
Ownership of the code, the data and the hosting are agreed in writing in the proposal before work starts.
Can you work on a system we already have?
Yes. We can improve, modernise or support existing software, and connect it to new tools.
Where will it be hosted?
On our servers or on yours — we help you choose what is simplest to run and support.
Will you keep our details confidential?
Yes. We can sign a confidentiality agreement before you share detailed requirements.
Tell us what you want to build.
Share the problem, the people who will use it and any deadline. We will come back with questions and a clear next step.
