A shop can have a full lot and techs working every day, and still come up short at the end of the month. One of the reasons we see most often is technician efficiency.
What technician efficiency means
Every hour a tech is on the clock costs you wages, payroll taxes and benefits. You only get paid back for the hours that end up billed to a customer on a repair order. Technician efficiency is how those two compare: the time you pay for against the time you actually sell.
What we found in one shop’s financial review
A shop asked us to go through its finances and look for holes, because sales looked fine and the bank account didn’t. Along with a few other problems in the books, we found the techs were billing about three of every four hours they were paid.
Nobody was slacking, and the shop was busy. But roughly a quarter of the tech payroll was going to time that never made it onto a repair order, and that came straight out of labor profit.
Why it happens in busy shops
Low efficiency is rarely about one lazy tech. It usually comes from the way work moves through the shop: how jobs get scheduled, priced and handed off, and how time gets written down. In a busy shop those things get rushed, and small gaps in the day add up without anyone noticing.
What low efficiency costs a shop
An unbilled hour costs you twice. You pay the wages, and you lose the labor sale that tech and that bay could have produced. A few hours a week per tech doesn’t feel like much on a Tuesday. Over a year, across a full crew, it can be one of the biggest numbers in the business that nobody is looking at.
It also hides well. It doesn’t show up as empty bays or idle techs. It shows up as labor profit that’s thinner than it should be, and an owner who can’t figure out why a busy month didn’t pay.
Why the books often don’t show it
On a lot of P&Ls we open, there’s no way to see this at all. The information lives in different places, and it isn’t put together in a way an owner can read. So the shop feels busy, the P&L feels off, and nobody can connect the two.
The short version
- Technician efficiency compares the time you pay your techs for with the time you sell.
- A busy shop can still lose a lot of paid time.
- It usually comes from how work moves through the shop, not from the techs themselves.
- Most shop books aren’t set up to show it.
