Frequently asked questions
How often are new NAICS 541990 bids added?
EasBid reads its state, city, county and school sources every 4 hours, and federal notices from SAM.gov on the same 4-hour cycle. Every listing links to the agency's original notice.
How do I get new NAICS 541990 bids by email?
Enter your email in the free alert box on this page. The free alert is one email a week with that week's new matches, and it needs no card. Pro emails new matches hourly, 9 AM to 5 PM your time.
Can I submit a bid through EasBid?
No. EasBid helps you find opportunities. You respond through the issuing agency's own process, which is linked on every bid.
Do I need to register as a vendor first?
Usually yes. Most agencies ask vendors to register on their own purchasing portal before they can respond, and federal work needs a SAM.gov registration. The notice says where to register.
