Key takeaways

  • Federal agencies obligated $14.9 billion on advertising contracts in fiscal years 2014 through 2023; about 14 percent ($2.1 billion) went to small disadvantaged businesses and businesses owned by minorities and women.
  • Common ways agencies buy marketing services: GSA MAS SIN 541810 Advertising Services, GSA MAS SIN 541613 Marketing Consulting Services, GSA MAS SIN 541820 Public Relations Services.
  • Rules to plan for: Publicity or propaganda prohibition, Grassroots lobbying ban, Section 508 accessibility for video and social media.
  • A contract vehicle or vendor registration makes buying easier, but it doesn't create demand. The vendors that win reach program owners before budgets and bids are set.

Who buys marketing services in government

Purchases of marketing services happen across federal agencies, states, counties, cities, school districts and colleges, hospitals, tribal governments, special districts and public utilities. The people you'll deal with usually include:

  • Agency public affairs and communications directors
  • Military recruiting commands
  • Public health departments running awareness campaigns
  • State tourism, lottery and economic development agencies
  • Transit agencies and utilities running customer outreach
  • University marketing and enrollment offices
  • City and county public information officers

The purchasing office runs the process, but the program owner who has the problem usually decides what gets bought. Reach both. See government buyer roles for how they work together.

The government marketing services market

How agencies buy marketing services

Small purchases under an agency's threshold can often be made with a quote or a purchase card. Larger purchases need a formal bid or an existing contract. These are the contract vehicles agencies commonly use for marketing services:

Contract vehicleWhat it is

Rules and requirements for selling marketing services

RequirementWhat it means for you
Publicity or propaganda prohibitionFederal appropriations bar agencies from paying for self-aggrandizing, covert or purely partisan communications, so campaigns must clearly show the agency as the source and stick to official business.
Grassroots lobbying banAgencies cannot use funds for clear appeals urging the public to contact Members of Congress about pending legislation, so campaign copy must avoid that.
Section 508 accessibility for video and social mediaFederal video and social content you produce must be accessible, such as captions and audio description, so people with disabilities can use it.
Small and disadvantaged business trackingCongress and GAO track how much federal advertising goes to small disadvantaged, minority-owned and women-owned firms, so small business status and teaming plans can matter in awards.

Requirements vary by agency and contract. Read each solicitation's terms, and check with the buyer when in doubt. This isn't legal advice.

Buying signals to watch

These events often mean an agency will buy marketing services soon:

  • A new public health, safety or benefits program that needs public awareness
  • Recruiting shortfalls at military services or public agencies
  • A new grant that includes an outreach or education budget line
  • Launch of a new transit line, toll system, utility rate change or customer program
  • A tourism or economic development agency receiving new funding

A sales process for selling marketing services

  1. Register. Get into SAM.gov for federal work and each state or local vendor portal you'll sell into. Use our vendor registration checklist.
  2. Pick your path to purchase. Decide which contract vehicles above fit your target buyers, and whether a reseller or partner already holds one.
  3. Build the target list. Identify the agencies with the need, the budget and the buying authority, and the people who own the problem.
  4. Start conversations early. Reach program owners while budgets and requirements are still being written, not after an RFP is posted.
  5. Follow through to purchase. Help the buyer pick the method, whether a cooperative purchase, quote or formal bid. When a bid comes, use our RFP response guide.

FAQ

Frequently asked questions

How much does the federal government spend on advertising?
GAO found federal agencies obligated $14.9 billion on advertising contracts from FY2014 through FY2023.
Which GSA schedule SINs cover marketing and advertising?
The MAS Marketing and Public Relations SINs include 541810 Advertising Services, 541613 Marketing Consulting Services, 541820 Public Relations Services, 541430 Graphic Design Services, 512110 Video/Film Production, 541910 Marketing Research and Analysis, and 561920 event planning.
Are there limits on what government ads can say?
Yes. Federal appropriations law bars publicity or propaganda, meaning self-aggrandizing, covert or purely partisan messages, and bars urging the public to lobby Congress on pending bills.
Do government videos need captions?
Federal agencies follow Section 508, which calls for accessible video, including captions, so plan for this in your production costs.
How long does it take to sell marketing services to government?
It depends on the size of the purchase and how it's bought. Small purchases under an agency's threshold, or buys through an existing cooperative contract, can move quickly. Purchases that need a formal bid or a new budget line usually take longer, often a full budget cycle.
