Built from real jobs, and years of billing pain
The business rules sit inside SubTrack, and teams that bill here get time back, so switching stings. You cannot Google or ChatGPT what you earn on site: LEM revisions, renaming and recombining PDFs that still get declined, hundreds of T&M edge cases, and how foremen, PMs, engineers, and subs act when pressure hits, including where to give leeway and where software must do the work before code is final. The same foundations scale from small contractors to large organizations, with crews and PMs first. The logic lives in the application and a decade of scar tissue behind it. Good luck copying that.
