Compressed air, HVAC, plumbing and electrical. One platform.
Your compressor techs, your HVAC techs and your plumbers and electricians work from the same app, the same customer list, the same schedule and the same bill. Each tech sees the tools, checklists and Ask a Tech for the trade they are working in. The office sees everything.
Coming to the App Store and Google Play.
What multi-trade companies tell us, and what we did about it.
"We run two systems and they never match."
One customer record for the plant that buys compressor service, a rooftop unit replacement and a panel upgrade. Every job, quote and invoice for every trade sits on that one customer.
"My HVAC guys don't need compressor screens."
The admin decides who works in which trade. A tech who only does HVAC only ever sees HVAC. A tech who does both switches with one tap on the home screen.
"Dispatch can't see who's free across the shop."
One dispatch board for everyone. Filter by trade, or see the whole day. Each job carries its trade, so the right checklist and the right expert help come with it.
"Starting compressor work means starting from zero."
Turn on compressed air and the support system is already there: the OEM manual library behind Ask a Tech, controller fault codes and access codes, the kit library and your OEM to aftermarket parts list.
"We pay for two subscriptions."
One plan. Your first trade is in the base price, and each extra trade is a small add-on per field seat. Office seats never pay twice.
"Accounting gets two of everything."
One QuickBooks or Xero connection for the whole company, one set of invoices and one payment setup.
Every trade you do, in one place.
Turn on the trades your company works in. Each one brings its own tools, equipment types, checklists and expert help. The business side is shared.
