Ask two shops to estimate the same brake chamber replacement and you can get two completely different numbers — not because either shop is wrong, but because one is quoting Standard Repair Time at a higher hourly rate and the other is billing actual wrench time at a lower one. Without a documented standard behind either quote, a customer has no way to tell a fair estimate from a padded one, and a shop has no way to prove its numbers hold up. Start free and build repair estimates from your own shop's actual time data.

A Repair Quote Without a Time Standard Behind It Is Just a Guess
Two shops, the same repair, two different numbers — and no way for anyone to tell which one is accurate without a documented labor standard underneath it. Truck Inspection & Maintenance Management Software tracks actual technician time against Standard Repair Time on every job, so estimates stop being a guess and start being a number backed by your shop's own history.
Standard Repair Time vs. Actual Time — Two Different Ways to Quote the Same Job
Both approaches are legitimate; they just produce different numbers for reasons a customer doesn't automatically see.
Standard Repair Time (SRT)
- Pre-published time from a VIN-specific labor guide
- Customer pays the quoted time, not the actual time spent
- Typically fewer billed hours at a higher hourly rate
- Shop absorbs the cost if the repair runs long
Actual Technician Time
- Billed on the real hours the technician spends on the job
- Typically more hours billed at a lower hourly rate
- More variable — a quick tech costs the customer less
- Harder to compare quotes across different shops
Why VMRS-Coded SRTs Beat a Shop's Own Gut Feel
The American Trucking Associations' Technology & Maintenance Council surveyed fleets and service providers to establish baseline average repair times across dozens of commonly performed labor tasks, coded to the Vehicle Maintenance Reporting Standards system. That gives a shop something a gut-feel estimate never can: a repair time that's comparable across providers and specific enough to plan bay assignments and technician scheduling around.
What VMRS-coded data actually unlocks Comparing actual repair times against SRTs by VMRS code reveals shop efficiency and technician performance patterns that a flat average never would — a technician consistently running 20% over standard on one repair category but right on target everywhere else is a training opportunity, not a productivity problem.
The Hybrid Approach Most Successful Shops Actually Use
Flat-Rate for Routine WorkPM services and common repairs with well-established, predictable time standards
Actual Time for DiagnosticsTroubleshooting and complex issues where the time genuinely varies job to job
Roadside MultipliersA roadside repair commonly runs 1.3 to 2.2x shop time depending on conditions and access — and should be quoted accordingly, not at shop rate
Document Actual Time Either WayEven on flat-rate jobs, logging real time spent is what makes future estimates more accurate
Calibrating Estimates to Your Own Shop's Reality
Track actual vs. SRTEvery job logged against the standard it was quoted from, not just closed and forgotten
Review quarterlyStandards that drift from a shop's real performance need regular recalibration, not a one-time setup
Refine by VMRS codePatterns show up by repair category long before they show up in an overall average
Feed it back into quotingA shop's own historical data becomes the most accurate estimate source it has
Estimates Backed by Your Shop's Own Numbers
Our Truck Inspection & Maintenance Management Software tracks actual technician time against Standard Repair Time on every work order, coded and comparable across jobs, so every future quote is grounded in what your shop actually does — not a generic guide or a guess.
Frequently Asked Questions
Why would a customer pay more under SRT billing even if the repair finishes faster?
SRT billing quotes the published standard time for the job regardless of how fast or slow the actual repair goes — the customer pays the quoted amount whether the technician finishes early or the job runs long, barring unforeseen additional work. That predictability is the trade-off for a typically higher hourly rate.
Start free and compare both billing models against your own shop's data.
Should every repair in a shop use the same billing method?
No — a hybrid approach is common and often works best: flat-rate or SRT billing for routine, well-defined repairs with established time standards, and actual-time billing for diagnostics and complex issues where the time genuinely can't be predicted in advance.
How often should a shop's labor time standards be reviewed?
A quarterly review cadence is a commonly recommended baseline, since equipment, technician skill levels, and shop processes all shift over time — standards calibrated once and never revisited tend to drift away from what the shop is actually capable of.
Why should roadside repairs be quoted differently than the same job in the shop?
A roadside repair involves conditions a shop bay doesn't — limited tool access, weather, traffic exposure, and often more difficult positioning — which is why roadside work commonly carries a time multiplier over the equivalent shop-based repair rather than being quoted at the same rate.
