One system.
Every trade.

TOS started in HVAC because that's where the gap was most visible, skilled professionals doing serious work with no system built for how they actually operate. But the problem isn't unique to HVAC.

Electricians, plumbers, welders, every trade professional dealing with field jobs, labor tracking, parts, invoicing, and growth faces the same wall. TOS is being built to knock it down across all of them.

Phase one is HVAC and refrigeration. The architecture is already designed to scale beyond it.
