What Is a Labor Guide?

Short answer: A labor guide is a reference, printed or electronic, that lists standard labor times for repair operations on specific vehicles and components. Repair shops use it to write estimates and bill flat-rate jobs, and to compare actual time with the standard. The time it lists for a job is often called book time.

How shops use a labor guide

  • Estimates. The guide gives a labor time for each operation, which the shop multiplies by its labor rate.
  • Flat-rate billing. On flat rate work, the customer pays the guide time, not the actual time.
  • Consistency. Two service writers quoting the same job should get the same labor number.
  • Performance. Comparing guide time with actual time is how shops measure technician efficiency.

What a guide does not cover well

Standard times assume normal conditions and the right tools. They may not reflect rusted or seized parts, previous repairs, aftermarket equipment, roadside conditions or long diagnostic work. Many shops bill diagnosis on actual time for that reason. State on the estimate whether labor is billed at guide time or actual time.

Shop-built guides

Shops that do many repeat jobs, such as PM services, inspections or common brake jobs, often build their own standard times from their history. Track actual time per job type, review it, and set a standard the shop can stand behind. Update it when equipment or methods change.

Heavy-duty considerations

Heavy trucks and equipment vary widely in configuration, so the same job can take very different times across makes, engines and axle setups. Record the unit, VIN and configuration on every job so times can be compared fairly.

Industry codes

Labor times are often organized by component systems. Many fleets use VMRS codes from the ATA Technology and Maintenance Council to classify repairs. See VMRS codes.

MetaFleet note

MetaFleet's AI writes repair lines from technician shorthand with suggested labor hours, and the shop adds parts. Labor guides are not built in. MetaFleet does not connect to MOTOR or Mitchell 1 today, so shops that need a built-in labor guide now should take that into account.

Questions

Is a labor guide time the same as book time?

Yes. Book time is the standard time a labor guide lists for an operation.

Does MetaFleet include a labor guide?

No. Labor guides are not built in, and MetaFleet does not connect to MOTOR or Mitchell 1. The AI suggests labor hours on the repair lines it writes.
