03 — Process

Four steps and no surprises: you approve the scope before work starts and the site before it launches.

01

Discovery

A short call or email exchange about your goals, your customers and what is not working today. Free, with no commitment.

02

Proposal

A written scope, timeline and fixed price, so you know exactly what you are getting before anything starts.

03

Development

The work happens on a staging site you can open at any time, with plain-language updates at agreed checkpoints.

04

Delivery

Testing, a launch in a low-traffic window, documentation and a handoff session, then support while your team settles in.

Tell me what you need. You’ll get a fixed quote, a timeline, and a clear next step within one business day.
