FAR 8.002 prioritizes the order in which purchasers must consider various sources when looking to buy services. The ordering activity must check first with the services on the Procurement List maintained by the Committee for Purchase from People Who Are Blind or Severely Disabled (AbilityOne). If the services are not available, continue through the sources until all three are exhausted. If nothing is available there or if the services involve classified or sensitive information, the purchaser can look to make purchases throughout other commercial sources on the open market acquisition.
Note: Acquiring activities should determine if the required service or supply is available through GSA Schedules before considering any other commercial source.
