Flat rate is a price a customer pays for a specific service based on the amount of time deemed necessary to perform the service, which remains constant regardless of the actual time a particular worker needed to complete the service. Flat rate manuals are used throughout the service industry and are based on timed studies of the time it takes to perform a specific job. At My Mechanic Automotive, our flat rate pricing helps provide a uniform pricing menu for service work and helps establish the worth of the performance of a particular job.
