Will it work for new construction and service work?
Yes. Use it for new commercial construction, tenant improvements, rooftop changeouts, PM contracts, and service calls. Attach drawings, specs, and equipment info to each job.
Built for commercial mechanical contractors. Run rooftop installs, service calls, and commissioning from one simple platform. Your techs log hours and forms from the field. Your PMs see progress in real time. Your office invoices the same day the job closes.


What your tech does on the rooftop shows up in the office in real time. No lost paperwork. No phone tag. No chasing signatures 30 days later. Install, service, and PM crews all work from the same system โ on their phone or tablet.
Startup reports, PM checklists, refrigerant logs, safety forms โ send the right form to the right job. Techs fill it out on the rooftop or in the mechanical room. Office reviews and approves from the same dashboard. No more binders. No more scanning.

One app from the first job at 7am to the last service call at 5pm. Techs see their schedule, clock in, pull equipment info, capture photos, fill out forms, and submit service tickets โ all before they pack up the truck. Simple enough for any tech. Works offline.

Every mechanical contractor has their own startup report, PM checklist, and safety forms. Drag and drop to rebuild the exact forms your techs already use on paper โ text, checkboxes, photos, signatures, risk ratings. Live in 10 minutes. No developer needed.

Monday morning: PM visits, installs, and service calls all in one view. See who’s certified, who’s free, and who’s closest to the job. Drag and drop to assign. The tech gets the address, scope, and customer history on their phone. No 7am ‘where am I going’ calls.
