Flat rate
What is flat rate: the pay system explained
Flat rate is a pay system in which a technician is paid the published book time for a job rather than the hours actually spent on it, so the pay for a brake replacement is the same whether it takes 45 minutes or two hours. The workshop bills the customer that same book time, which is the appeal: labour cost and labour revenue move together.
You will also see it called flat-rate pay, flag pay or book time pay. The hours a technician earns are described as flagged, sold or booked hours.
How is flat rate pay calculated?
Technician pay = flagged hours x the technician's flat rate per hour
The flat rate per hour is what the shop pays the technician. It is a different number from the labour rate charged to the customer, and the gap between the two is the labour gross profit.
Worked example in dollars, though the arithmetic works in any currency. A technician on a flat rate of $25 an hour completes a job the labour guide prices at 2.4 hours. She finishes it in 1.6. She is paid 2.4 x $25, so $60, for 1.6 hours of bench time, which works out at $37.50 an hour. The customer pays 2.4 hours at the shop's labour rate regardless.
Now the same technician takes 3.5 hours on a seized exhaust job booked at 2.0. She is still paid 2.0 x $25, so $50, for three and a half hours of work. Her earnings on that job are about $14.30 an hour. Across a week the wins and losses are meant to average out, and on routine work they usually do.
Because the two clocks run independently, a technician who beats the book flags more hours than they attend. That is why technician efficiency, sold hours divided by clocked hours, routinely reads above 100% in a flat-rate shop and should.
Where do the book times come from?
Two sources, and the difference matters to the person being paid.
- Manufacturer warranty times, published by the OEM for warranty work. Set by the party paying the bill, and generally tighter.
- Independent labour time guides, compiled from observed repair times by publishers such as Motor, Mitchell 1 and Alldata, used for customer-pay work.
Times are derived on a vehicle in reasonable order. A ten year old car in a salted climate is not that vehicle. Diagnostic work fits the model worst of all, because the time needed to find a fault is not knowable in advance, which is why many shops carve diagnostics out and pay them hourly.
Why flat rate is contested
The arguments on both sides are real, and shops that have run both systems tend to acknowledge that.
The case for it:
- It pays for skill. A technician who has invested in training and tooling earns more than one who has not, on the same job, without a manager having to arbitrate.
- Labour cost tracks labour revenue. When the workshop is quiet the wage bill falls, which is the reason many small shops adopted it in the first place.
- It removes an argument. The time is published in advance, so nobody negotiates what a job was worth afterwards.
The case against it:
- It pays for speed, and speed is not always quality. The same incentive that rewards a skilled technician for finishing early rewards a rushed one for skipping the road test, the second inspection, or the torque check.
- Comebacks are usually unpaid. A job that returns is typically rectified on the technician's own time, so the cost of a mistake lands on the individual. That is a real correction against corner-cutting. It also means a callback rate problem surfaces as a pay dispute rather than a technical review.
- The technician carries demand risk they cannot control. An empty ramp, a parts delay or a slow week costs the technician money even though scheduling, stock and marketing are all someone else's job.
- Job allocation becomes the real pay decision. Quick, well-paid jobs and slow, awkward ones are handed out by whoever runs the board, so the dispatcher effectively sets earnings.
- It is hard on people who are still learning. An apprentice technician beats no book times, so flat rate would pay them close to nothing. Almost every shop pays trainees hourly for exactly this reason, which is a quiet admission about how the system works.
Flat rate pay and the law
Flat rate changes how pay is calculated, not whether wage floors apply. In the US, section 213(b)(10)(A) of the Fair Labor Standards Act exempts a "salesman, partsman, or mechanic primarily engaged in selling or servicing automobiles" at a retail dealership from overtime. That exemption sits in subsection (b), which disapplies only section 207, the maximum hours rule. Section 206, the minimum wage, is untouched, so flat-rate earnings still have to clear minimum wage measured against hours actually worked rather than hours flagged. Shops handle it with a guaranteed weekly floor or a top-up. Other countries have no such overtime carve-out, and test output-based pay against the national minimum wage the same way.
Flat rate pay is not flat rate pricing
The same phrase means something different on the customer side of the counter. Flat rate pricing, sometimes called menu pricing, is quoting a single fixed price for a job instead of time plus parts. A shop can quote flat rate prices while paying its technicians hourly, or the reverse. Check which side of the transaction the term refers to.
What shops use instead
Most alternatives are hybrids rather than a return to straight hourly. The common one is a guaranteed hourly base plus a production bonus above an efficiency or flagged-hours threshold, which keeps some upside for speed without letting a bad week wreck someone's pay. Others attach bonuses to comeback rates and inspection completion, or pay diagnostics hourly and keep flat rate for repair. Each choice moves the incentive somewhere. None removes it.
