GSA Form 3521: Blanket Purchase Agreement
GSA Form 3521, Blanket Purchase Agreement, is a General Services Administration form. Its header names the General Services Administration, and its footer reads GSA FORM 3521 (REV 4-92). GSA hosts it in its forms library, and GSA's page lists APD 2800.12B as the authority.
The two-page agreement is a letter signed by a contracting officer to a supplier. The form says the supplier agrees to furnish the supplies or services described, if and when ordered by the contracting officer or an authorized representative during the term. It sets out pricing, a purchase limit, the GSA employees authorized to place orders and their dollar limits, how orders are placed, what delivery tickets show and where invoices go. The supplier accepts by signing and returning a copy. The form prints no OMB number and no privacy statement.

What's on GSA Form 3521
Term, area and extent of obligation
The agreement becomes effective upon acceptance by the supplier and stays in effect until a date entered. The form has a space for the geographic area served and says the government is obligated only to the extent of authorized purchases actually made.
Pricing and purchase limitation
Purchases are based on a written quotation in response to Standard Form 18, Request for Quotation, or an oral quotation. The form says any one purchase shall not exceed $10,000, and lower amounts may be set for named individuals.
Authorized individuals and placing orders
A table of name, organization and dollar limit per purchase. The form says no written orders will be placed; orders are placed by telephone or in person with five listed details.
Delivery tickets and invoices
Eight items each delivery ticket or sales slip shows, such as supplier name, BPA number, purchase number and itemized supplies, and the address for invoices.
