GSA Form 300: Order for Supplies and Services

GSA Form 300, Order for Supplies and Services, is a General Services Administration form, Rev. 11/2021, and GSA hosts it in its forms library. GSA's page lists the authority or regulation as APD 2800.12B.

The one-page order is addressed to a contractor in block 6 and comes from the issuing office in block 10. Block 7 sets the type of order: a purchase, a delivery order for supplies, a task order for services, or a modification. The form asks for the order and contract numbers, accounting data for government use only, the contractor's Unique Entity Identifier (UEI) and Taxpayer Identification Number (TIN), business classification, addresses for remittance and shipping, a schedule of items and prices, and signatures from the contractor and a contracting or ordering officer. The schedule has a line for the total from GSA 300A(s). It prints no instructions, OMB number or privacy statement.
