Why not just set up a saved search on SAM.gov?

You can. Here's what it misses.

Bids with no location

On the day we checked, 17 of 41 open HVAC notices had no state listed. A state filter skips them. When SAM.gov leaves the location blank, we read the notice to find it.

Only what you can bid on

Tell us your certifications once. Set-asides you don't qualify for stay out of your inbox — and if you're veteran-owned, the bids reserved for you are clearly marked.

The fine print, flagged

Moved deadlines, pending amendments, required site visits. One sentence, at the top, before you spend an evening on a bid you can't win.

A real one, from this week
Heat pump project, USDA Forest Service, Arkansas. Small business set-aside. Due Oct 20.
BidSentry flag: Offers are only considered from firms that attended the Sept 24 site visit, and no second visit is planned. If you weren't there, skip this one.

Questions

Is BidSentry part of the government?

No. BidSentry is a private service. We read public notices on SAM.gov and send you the ones that fit. Always confirm details in the official notice before you bid.

Do I need to be registered in SAM.gov?

To submit a federal bid, yes. SAM.gov registration is free — never pay anyone to register or renew it for you.

What if a week goes by with nothing in my area?

Then we don't email you. You hear from us when a new bid matches or a deadline is close.

How do I cancel?

One click in your settings. Cancel during the trial and you're never charged.
