Receptionist for HVAC contractors
When the AC dies in July, the customer calls four contractors and books with the first one who picks up. If your office is on a job site, that's not you.
Receptionist for plumbers
A burst pipe at 6pm is an emergency for the customer and a booked job for you — but only if someone answers. Under a sink, you can't, and the caller dials the next plumber on Google.
Receptionist for electricians
Fault-finding, a dead consumer unit, a tripping circuit — the customer wants it fixed today. If you're mid-install and can't pick up, that booked job goes to the next sparky.
