Definition
"Flat rate" is used in two related ways in repair shops.
- Flat-rate pricing: the shop charges a fixed number of labor hours for a defined job, often taken from a labor guide or the shop's own history, multiplied by the posted labor rate. The customer knows the labor price up front.
- Flat-rate pay: the technician is paid for the hours assigned to the job, not the clock hours spent. Ratchet+Wrench gives the example of a timing belt job that pays six hours done in four: the technician is still paid six hours.
Why shops use it
Flat-rate pricing makes estimates predictable and rewards efficient technicians. It also moves risk: if the job takes longer than the set hours, the shop or the technician absorbs the difference; if it takes less, they gain.
Where it goes wrong in heavy-duty work
Seized fasteners, rust and road-call conditions can make real time far longer than a guide time. Shops that price flat should define what the flat price covers and what triggers an additional authorization, and write that on the estimate. Comebacks on flat-rate jobs are usually unpaid time for someone.
Measuring it
Compare flat hours billed with clock hours worked by technician. That ratio is technician efficiency. Total labor dollars divided by billed hours is your effective labor rate.
In software
MetaFleet does not include a third-party labor guide today. It suggests labor hours on AI-drafted repair lines, which the shop reviews and edits, and records technician time with a time clock; see AI invoicing and technician time clock. See also book time and labor guide.
