When a contractor buys materials, he or she takes them to the contractor checkout
desk. The clerk enters the contractor name into the system. The system displays
the contractor information, including his/her current credit standing.
The clerk then opens up a new ticket (sale) for the contractor. Next, the clerk then
scans in each item to be purchased. The system finds the price of the item and
adds the item to the ticket. At the end of the purchase, the clerk indicates end of
sale. The system compares the total amount against the contractor’s current credit
limit, and if it is acceptable, finalizes the sale. The system creates an electronic
ticket for the items, and the contractor’s credit limit is reduced by the amount of
the sale. Some contractors like to keep a record of their purchases, so they request
that the ticket details be printed out. Others aren’t interested in a printout.

The variable costing concept removes fixed costs, which are uncontrollable, from the decision-making process (see variable costing income statement).
