Bay and lift throughput
You sell one billed hour in one bay
You are renting time on a machine and a technician at the same time. The posted labor rate is fiction; the number that pays your bills is the effective labor rate - total labor dollars divided by total hours you paid for. Parts margin and shop supplies are real profit, but they never rescue a shop that gives away hours.
- Your ceiling
- Bay hours. A lift sitting empty at 2pm is inventory you can never sell again.
- Biggest leak
- Diagnostic time you never bill — An hour of chasing an electrical gremlin is an hour of bay time. Sell diag as a product with a deliverable.
