Build your reputation as solidly as you build extensions.
The ridiculously simple client management software built for builders and general contractors. Manage multi-phase projects, coordinate with clients, and collect stage payments without the chaotic paperwork.
No credit card required. Setup takes 2 minutes.
Quote: Single Storey Extension
Variations get agreed verbally and forgotten, stage payments are chased weeks late, and your client thinks the schedule has slipped when it hasn't. CMA gives you a single source of truth that both you and the client can rely on.
Break projects into phases — foundations, first fix, second fix, snagging — each with their own line items and costs. Clients know what to expect at every stage.
Store plans, building control sign-offs, and progress photos against each project. Everything the client needs is in their portal.
Invoice at each project milestone and let clients pay online. No more awkward conversations about overdue payments.
CMA gives clients visibility without constant phone calls:
Upload progress photos - Share weekly updates through the client portal.
Hit the milestone - Mark phases complete and trigger the next stage invoice.
Client signs off - Digital approval keeps everything documented.
Payment lands - Client pays via card and you move to the next phase.

"My extension clients used to ring me five times a day asking for updates. Now they log into the portal and see everything. I can actually get on with building."
