Before we start

A few useful answers.

Can we start before every requirement is clear?

Yes. Tell us what you want to improve, who will use it and the tools you have today. We reply within 24 hours of receiving your inquiry and prepare an initial solution based on your brief. The first consultation is free and helps clarify the direction and any information still needed.

Can you work with an existing site or system?

We can review the code, data, access and operating environment before recommending continued development, targeted improvements or a rebuild.

How are scope, pricing and acceptance agreed?

We assess the scope, complexity and delivery requirements, then agree deliverables, milestones, fees and acceptance criteria before development.

What happens after launch?

Code, documentation, deployment access and maintenance scope are agreed for the project. Ownership, ongoing support and service terms are defined in the agreement.

What would you like to build?

A few sentences are enough to start. Bring a new idea or a problem in a system you already use.
