Technician Efficiency vs. Productivity: Where the Clocked Hours Go

Why the published definitions disagree

Read three guides and the words swap places. Some call billed hours over hours at work “productivity”; others reserve that word for hours on repair orders over hours at work and call the billed figure “proficiency” or “overall.” Several are written for dealership service departments, where warranty pay, a dispatcher and a separate parts department change what the numbers mean. None of that is wrong. It only means a shop comparing its figure with a published target may be comparing two different divisions.

The fix is a written definition, kept the same every week: which hours go on top, which go underneath, and whether shop time — cleaning, shuttles, training — counts as time at work or comes out first. The trend of one shop’s own number, counted the same way, is worth more than any published benchmark.

Pay plans hide the gap in different places. The Bureau of Labor Statistics notes that some repair shops pay technicians on an hourly basis, while others pay them based on the amount of work completed. Under hourly pay, every unbilled hour is a paid wage with no revenue against it. Under flat rate, the tech carries much of it in lost earnings — but the shop still carries the bay that sat idle, the cars that waited and, as a later section shows, the overtime arithmetic.

Where hours that are clocked but not billed go

The gap between hours at work and billed hours is not one leak. It is several small ones, each with its own fix and its own owner. One owner on an industry forum put the difficulty plainly: “Accurately billing customers for time has been the hardest problem for me to solve.” Sorting the hours by cause is what makes the problem countable.

• Waiting on parts. The car is on the lift, the part is on a truck, and the tech is clocked onto the job or standing at the counter.
• Waiting on approval. The inspection is done, the estimate is written, and the customer has not called back — with the car still in the bay.
• Diagnosis not billed. Testing time that the repair order folds into the repair, writes down at the counter or gives away to save the sale.
• Comebacks and rework. A second visit on the shop’s own work, clocked as a job and billed at nothing.
• “While we’re in there.” Work done during the job that never became a line on the ticket.
• Clocking errors. Time clocked onto the wrong repair order, or not clocked at all, so a busy hour looks idle in the report.
• Shop time. Cleaning, shuttles, moving cars, training — real work that no customer pays for directly.

Some of these are the price of running a shop; nobody expects shuttle runs to bill. Others — the approval that waited three hours, the diagnosis given away, the add-on never written up — are money the work already earned.

A one-week count by hand

No new software is needed for a first count. One person, the shop management system’s reports and one ordinary week are enough.

• Export each tech’s punch-in and punch-out times for the week from the time clock or payroll.
• Export each tech’s time clocked onto repair orders for the same days, from the technician report of the shop management system. If the system does not track job clocks, the week’s count starts with the techs writing start and stop times on each RO.
• Export billed or flagged labor hours by tech from the closed repair orders.
• Put the three counts side by side, per tech, per day, and compute the two ratios and the overall figure.
• For the same week, ask each tech to write one line whenever they wait more than fifteen minutes: the RO number, the reason and the minutes. A clipboard by the time clock is enough.
• On Friday, sort the gap for each tech into the causes above, and total each cause in hours.

Then a first dollar figure. Illustrative example, not a client: a shop finds 40 hours in the week that were spent on cars and never billed — waiting on approvals, diagnosis written down, add-ons never added. At an assumed posted rate of $150 an hour, that is $6,000 of labor in a week. It is the ceiling, not the loss: some of that time could never have been billed. The owner decides which share was realistically billable and writes the range down. The count, repeated the following week with the same definitions, becomes the shop’s own trend.

The overtime question flat-rate pay does not settle

This is the point the efficiency glossaries leave out, and it changes what unbilled hours cost an independent shop. The federal overtime exemption for mechanics, 29 U.S.C. §213(b)(10)(A), covers a mechanic “primarily engaged in … servicing automobiles” only if he is employed by a nonmanufacturing establishment primarily engaged in the business of selling such vehicles to ultimate purchasers. The regulation at 29 CFR §779.372 defines “primarily engaged”: over half of the establishment’s annual dollar volume of sales made or business done must come from sales of the listed vehicles. As written, the exemption is built for dealerships. An independent repair shop that sells no cars does not appear to meet that test.

Without that exemption, a tech paid by the flagged hour is a pieceworker under the federal rules. Under 29 CFR §778.111, a pieceworker’s regular rate is the week’s total earnings, including “any sums paid for waiting time or other hours worked,” divided by all hours worked in the week, and every hour past 40 earns an extra half of that rate. Waiting on the job counts as work: 29 CFR §785.15 lists employees who are working while they wait — a repair man waiting for a customer’s premises to be ready among them — and says that where waiting is an integral part of the job, the employee is “engaged to wait.” So the tech waiting for a part at 4:30 on a Friday is still working, and those hours count toward 40.

None of this is legal advice, and state wage law can add rules of its own. Before any pay plan changes, take the shop’s actual plan and its actual time records to an employment attorney or the payroll provider. The operational point stands on its own: unbilled hours are not free to the shop under any pay plan, and the time clock — not the flag sheet — is the record the law reads.

What closes the gap — process before pay plans

The first fixes cost a decision about who owns what, not a new system.

• Parts staged before the car enters the bay, checked against the repair order by whoever dispatches the work.
• One named advisor who owns every open approval call, with a time by which the customer is called back — and a rule for when the car comes off the lift to free the bay.
• Diagnosis written as its own priced line, so testing time is either billed or written down on purpose, with a reason.
• Every comeback linked to the original repair order, so rework shows up against the job and the tech that caused it.
• A rule that no add-on is done until it is on the ticket and authorized, so “while we’re in there” becomes a line instead of a gift.
• The same three counts, every Friday, with the same definitions.

Pay plans and bonus thresholds are a real lever, and they come after the count — and after an attorney has read them. Changing how techs are paid before knowing where the hours go moves the problem from one column to another.

When to leave the numbers alone

If the count shows high efficiency and low productivity, the techs are fast and the shop is short of work; the fix sits at the phone and the declined-work list, not in the bays. If a new tech is still learning the shop’s cars, a low efficiency figure is expected for a while and says nothing about the process. And in a one- or two-tech shop where the owner writes every ticket and sees every car, the owner already knows where the day went; there is no hand-off to lose yet.

Clocked-versus-billed hours are one of several places an auto repair shop’s money can leave after the work is done; declined work with no follow-up date, labor written down at the counter and fleet invoices that wait are others. Our Revenue Review counts each of them from the shop’s own records: two weeks, read-only, ending in a written report with a monthly dollar figure wherever the records support one. Nobody here runs a repair shop, and the Review gives no legal or repair advice. The free 20-minute call says plainly when the Review is not worth it.
