How a project works

Plan and design (Week 2). Designs you can click through and a plain-language plan for how it all fits your tools. You get: Clickable designs, Technical plan.
Build (Weeks 3 to 8). Short cycles with working pieces to review every week, tested against real use before anything goes live. You get: Weekly demos, Tested before launch.

Frequently asked questions

What does a project cost?

Every project gets a fixed quote after a short discovery call, before any work starts. Larger builds are scoped in phases, so you are never committed to more than you can see.

How long does it take?

Most websites launch in four to eight weeks. Custom software and AI tools depend on scope, and your quote includes a clear timeline.

Do we own what you build?

Yes. Once the project is paid for, the code, designs and content are yours.

Can you work with the tools we already use?

Usually. We connect to the CRM, accounting and scheduling tools you already run, and only suggest replacing something when it is genuinely holding you back.

What happens after launch?

We host, monitor and maintain what we build, on a monthly plan or as needed. You will never be left with a system nobody can fix.
