Avoid
Job Costing through the Payroll System
Some controllers have elaborate cost accounting systems set
up to accumulate a variety of costs from many sources, sometimes to be used for
activity-based costing and, more frequently, for job costing. One of these costs
is labor, which is sometimes accumulated through the payroll system. When this
is done, employees use lengthy time cards on which they record the time spent on
many of their activities during the day, resulting in vastly longer payroll
records than would otherwise be the case.
This is a problem when the payroll staff is asked to sort through and add up all
of the job-costing records, since this increases the workload of the payroll
personnel by an order of magnitude. In addition, the payroll staff may be asked
to enter the job-costing information that they have compiled into the
job-costing database, yet another task that gets in the way of processing the
payroll.
The obvious solution is to disallow job costing to be merged into
the payroll function, thereby enabling the payroll staff to vastly reduce the
amount of work they must complete, as well as shrink the number of opportunities
for calculation errors. However, this step may meet with opposition from those
people who need the job-costing records. Fortunately, there are several ways to
avoid conflict over the issue. One is to analyze who is charging time to various
projects or activities and determine if the proportions to time charged vary
significantly over time; if they do not, there is no reason to continue tracking
job-costing information for hours worked. Another possibility is to split the
functions so that the payroll staff collects their payroll data independently of
the job-costing data collection, which can be handled by someone else. Either
option will keep the job-costing function from interfering with the orderly
collection of payroll information.
