When creating a new Price Matrix the first thing that is asked of you is to specify the name. You will have to assign a rate for each Job Type and select the radio button to enable this rate. If enabled, Timestead will bill the Job type at the stipulated rate as a flat rate irrespective of time.
If the Job Type rate is not enabled, Timestead will bill the rate at an hourly fee according to the job duration inserted in the Jobsheet.
