Premier Painting Services, Inc. provides residential painting services for three home building companies, Glendale, Highwood, and Lexington, and it uses a job costing system for determining the costs for completing each job. The job cost system does not capture any cost incurred by Premier for return touch-ups and refinishes after the homeowner occupies the home. Premier paints each house on a square footage contract price, which includes painting as well as all refinishes and touch-ups required after the homes are occupied.

Each year, the company generates about one-third of its total revenues and gross profits from each of the three builders. The Premier owner has observed that the builders, however, require substantially different levels of support following the completion of jobs.
