New: A Contract's Amendments and Re-posts, All on One Page

Government buyers rarely post a contract just once. They post it, amend it, push the deadline back, and sometimes post it all over again — and many procurement portals publish each of those as a brand-new listing. Until now, each one was a separate page on ContractRadar, with nothing connecting it to the others. Starting today, on SAM.gov and 14 state and local portals, a contract’s page shows the whole story in one place: the original notice and every amendment or re-post after it, in a new Notice history.

An example

Connecticut’s state portal listed a window replacement job for the Plainfield Town Hall three separate times. The first listing closed October 6. The second said October 20. The third said November 10. Land on the first one and you’d reasonably assume you’d missed it by weeks — when the town was still taking bids.

Now whichever of those listings you find, the page shows all three notices in order. Open one of the earlier two and, right under its deadline, it tells you what changed: “Extended to Nov 10, 2026 by a later notice”. See the Plainfield page.

What you see

When a contract has more than one notice, its page gets a Notice history section. The original notice sits on top, with every later notice beneath it, oldest first, each with its own due date. The one you’re looking at is marked, and you can open any other notice’s page — or, with a free account, go straight to it on the source portal.

Why it matters

Missing an amendment is one of the easiest ways to lose a bid you’d otherwise win. Amendments change quantities, add site visits, answer bidders’ questions, and move dates, and many bid forms ask you to acknowledge every one of them. Notice history shows you at a glance that there is more than one notice, and which one is newest. It doesn’t replace reading the solicitation itself: some portals attach amendments as files to the original listing rather than posting a new notice, and those won’t appear here. Always pull the latest documents from the source before you submit.

Free, for everyone

Notice history is part of the contract page itself, and you don’t need an account to see it. With a free account you also get the source link for each notice.

On Pro: one alert per contract

If you use saved-search email alerts, they now treat a contract and its amendments as one thing, on the portals listed below. Once you’ve been matched to a contract, its later notices won’t show up in your inbox again as if they were new. The one exception is on purpose: if a later notice matches your search and you hadn’t been matched to that contract before, you’ll get it.

Where it works

Notice history works where a portal numbers its notices consistently enough for us to tell which ones belong together. Today that’s SAM.gov; the state portals of Arizona, Colorado, Connecticut, Kentucky, Maine, Michigan, Mississippi, Missouri, Rhode Island and West Virginia; and New York City, Honolulu, Palm Beach County, FL, and Mecklenburg County, NC. Everywhere else, each listing still stands on its own, and we’ll add more portals as we can group them reliably.

Search results still list each notice as its own result for now. Whichever one you open, its page shows the full history.

Try it

Head to the search page and open a contract from SAM.gov or one of the portals above — anything that was amended or re-posted as a new notice will show its Notice history. New here? Create a free account to get started.
