Red or Green is job profitability software for any trade, including HVAC, plumbing, electrical, and roofing shops, offering live margin tracking. It provides real-time profitability data to technicians, enabling shops to identify unprofitable jobs as costs arise rather than after books close. The software uses a four-step workflow: jobs are budgeted in about 60 seconds with trade-specific templates showing planned margins; receipt data is captured via photo recognition or manual entry, extracting vendor details automatically; active projects are displayed on a color-coded job board—green for on-target, amber for drifting, and red for underwater jobs. Upon job completion, variance analysis compares quoted figures to actual costs, breaking down labor and material differences to refine future estimates. Focused solely on profitability tracking, the mobile-friendly platform supports offline use, one-handed operation, and quick CSV exports for data portability.
