The firm, which bills $125 per hour for services performed, is in a very tight local labor market and is having difficulty finding quality help for its overworked professional staff. The cost per hour for professional staff time is $45. Selected information follows. Billable hours to clients for the year totaled 5,000, consisting of information systems services, 3,100; e-commerce consulting, 1,900. Administrative cost of $342,000 was (and continues to be) allocated to both services based on billable hours. These costs consist of staff support, $180,000; in-house computing, $136,400; and miscellaneous office charges, $25,600. A recent analysis of staff support costs found a correlation with the number of clients served.
