The fastest way to know whether keyplan fits your firm is to see one real project run through it. Your numbers, your site, your client.
keyplan was built inside a working firm, on live projects: to stop the quiet leads, the claims raised late, and the projects that ended at a loss without anyone noticing in time. Firm #0 still runs on it every day.
If you run a firm and want to see it on a real project before deciding anything, message me. I answer these myself.
