Alaska Launch, a private-sector aerospace company, provided the following aggregated data for satellite construction jobs during a recent period:

Direct materials   $13,442,769

Direct labor          $21,889,554

Applied (and actual) factory overhead   $8,223,454

Beginning work in process   $14,550,098

Ending work in process      $17,559,000

Satellites are usually constructed to specific customer specifications, and the contract selling price is 125% of cost.

Assuming that the above costs are attributable to several different satellites in various stages of production, how would the cost of direct materials, direct labor, and overhead be tracked to specific jobs? How important is the job costing system in establishing a fair selling price for each satellite?
