A processor may receive input data indicative of information about a particular vehicle repair shop (VRS). Based on that input data, the processor may determine a potential total extent of sales by the particular VRS over a particular time period. Also, the processor may refer to a data storage device containing computer-readable vehicle repair orders (ROs) each specifying a respective extent of sales by the particular VRS. Based on such ROs, the processor may determine an actual total extent of sales by the particular VRS over the particular time period. Further, based on the potential and actual total extents of sales, the processor may determine a sales efficiency of the particular VRS over the particular time period. Then, the processor may direct a display device to display a visual indication representative of the determined sales efficiency, the potential total extent of sales, and/or the actual total extent of sales.
