Why Get A GSA PSS Schedule Contract?

GSA PSS is the second most lucrative Schedule. In FY 2021, companies with a GSA PSS Contract had generated nearly $11 billion in sales, averaging out at $2 million each. Other benefits of being a GSA PSS Schedule Contractor include long-term business relationships in the federal market (GSA Schedules can last for up to 20 years), and access to exclusive government marketing and advertising tools like GSA eBuy and GSA Advantage!

Who can buy from the GSA Professional Services Schedule?

For the most part, the GSA Professional Services category is a procurement vehicle for federal buyers. The GSA PSS Schedule simplifies the procurement process so that federal agencies and vendors can conduct business with as little red tape as possible, thereby saving time and money for both parties. In certain circumstances, the Disaster Recovery Program also allows state, municipal and local government agencies to source services through the Schedule.
