Procurement portals rarely email you anything useful. They post, they amend, they move deadlines, and they expect you to keep checking. A change detector does the checking, which turns a daily chore into an alert that arrives while there is still time to bid.

How do you monitor RFPs and tenders automatically?
Point a change detector at the portal's search-results or listing page — the one showing current opportunities filtered to your categories — and select the results region. When a new notice appears, a deadline moves or an amendment is posted, the text in that region changes and you are alerted with the before and after. It works on any portal whose listings are visible without signing in.
Bid teams lose work for an unglamorous reason: they found out too late. A notice goes up on a Friday with a three-week window, nobody checks until Monday week, and what was three weeks of preparation becomes ten days. The opportunity was public the whole time.
The other half of the problem is amendments. Portals routinely revise scope, extend or shorten deadlines, publish clarification documents and post award notices — often with no notification at all to people who have not formally registered interest. Teams that only watch for new postings miss the changes to the ones they are already working on.
This guide covers watching both: the listing page for new opportunities, and the specific notices you are bidding on for amendments. It also covers the portals where this will not work, because there are several.
Most teams set up only the first and are surprised by the second.
Use the portal's own search to narrow to your categories, regions or classification codes, then watch the URL that filtering produces. This is the single highest-value watch you can set: it tells you when something new and relevant appears, without alerting on every notice the portal publishes.
Once you are working a bid, watch its page. Amendments, revised closing dates, added documents and answers to clarification questions all change that page, and portals are inconsistent about telling you.
Watching where awards are published tells you who won and at what value. That is competitive intelligence you cannot get any other way, and it costs one more watch.
It is mostly navigation and announcements. The filtered results URL is far more precise and produces alerts you will actually read.
Filter first, then watch. A watch on an unfiltered listing page will alert on every notice the portal publishes, and a bid team that mutes its alerts is back where it started.
Deadlines are the reason this matters more here than almost anywhere else.
For new opportunities, hourly is usually sufficient — portals do not publish minute by minute, and an hour of delay on a three-week window costs nothing. For notices you are actively bidding on, particularly in the final week, five or fifteen minutes is justified: a deadline that moves forward or a clarification issued at 4pm on a Friday is exactly the thing you cannot afford to see on Monday.
This is where metered tools become awkward. Watching twenty portal pages hourly is around 14,000 checks a month, which exceeds most mid-tier monthly allowances before you have watched a single live bid at five-minute intervals. Because our plans sell slots rather than credits, the frequency you need during the closing week costs the same as the frequency you need the rest of the year.
| What you are watching | Suggested interval | Why |
|---|---|---|
| Filtered listing page | Hourly | New notices do not appear minute by minute |
| A bid you are working on | Every 15 minutes | Amendments and clarifications arrive without warning |
| A bid in its final week | Every 5 minutes | A deadline change is unrecoverable if missed |
| Award / outcome pages | Daily | Useful intelligence, never urgent |
The difference between "the portal changed" and "a new notice matching your codes appeared".
Portals wrap their listings in navigation, filters, pagination and often a session-dependent header. Selecting just the results table means the alert shows you the new row rather than a page-wide diff.
If you only bid on work mentioning particular terms, require those words to be present before an alert fires. Everything else is still recorded, so you can review it without being interrupted by it.
Email works, but a Slack or Teams channel means the whole team sees a new opportunity at once rather than one person forwarding it. Chat and webhook channels are on every paid plan, with 2 to 10 destinations depending on the plan.
Every recorded version is kept with a full-page image, so when a deadline moves you can see exactly what it said before. In a procurement dispute, that record is occasionally worth more than the alert was.
A meaningful proportion of procurement sits behind exactly the barriers a hosted change detector cannot cross.
Many portals require registration to see notices at all. We cannot reach those, and no hosted change detector can without your credentials. If your key portals are all authenticated, this approach will not solve your problem and you should know that before subscribing.
If filtering produces no stable URL — the results only exist after a POST — there is nothing to watch. Check whether your filtered view has its own address before setting this up.
Some government systems reject anything that is not a browser session. We identify ourselves honestly rather than pretending to be a person, so a portal determined to refuse us will succeed.
Some frameworks notify registered suppliers directly and publish nothing. Registration remains the answer there; monitoring cannot substitute for being on the list.
Set up an alert for new tenders, amendments and deadline changes.
Use the portal's own search to narrow to your categories, codes or region, then copy the URL that filtering produces.
We load it and show it back to you as we fetched it, so you can confirm the listings are visible without signing in.
Click the listings table so navigation, filters and pagination are ignored.
Hourly for new opportunities; every five to fifteen minutes for a bid you are actively working on.
Slack, Teams, Discord, Telegram or a webhook on paid plans, so the whole team sees a new notice at once.
Watch each notice you are bidding on separately, so amendments and deadline changes reach you as well as new postings.
Typically about 5 minutes from start to finish.
Uptime monitors, watched pages and heartbeats each get their own allowance, so adding a page watch never costs you a monitor. SSL and domain checks ride along with the monitor they belong to and use nothing extra.
| Plan | Monitors | Watched pages | Heartbeats | Fastest interval | Alert channels | Price |
|---|---|---|---|---|---|---|
| Free | 1 | 1 | 1 | Every 30 minutes | 1 email address | $0 |
| Founding Member first 20 only | 25 | 25 | 25 | Every 5 minutes | Email + webhook & chat | $5/mo |
| Basic | 10 | 10 | 10 | Every 10 minutes | Email + webhook & chat | $8/mo |
| Growth | 50 | 50 | 50 | Every 5 minutes | Email + webhook & chat | $19/mo |
| Pro | 100 | 100 | 100 | Every 60 seconds | Email + webhook & chat | $34/mo |
Annual billing is cheaper on every paid tier. The pricing page is the authoritative list.
Every recorded change is compared word by word and kept with a before-and-after image. This is the real output, shown with worked example data.
Price fell from $49 to $39, and an annual discount was added.
The item is available again and the basket button returned.
A new subprocessor was added in another jurisdiction.
The free plan sends to one email address. Every paid plan adds the chat and webhook channels below, with 2 to 10 destinations depending on the plan. However many alerts you receive, the price does not change — nothing here is metered or charged per alert.
There are no voice calls and no SMS. If a phone call at 3am is a hard requirement, say so before you subscribe — we would rather tell you now than refund you later.
Filter the procurement portal to your categories, then point a change detector at the filtered results URL and select the listings region. When a new notice appears in that region you are alerted with the before and after. It requires no registration with the portal beyond whatever is needed to view listings.
Yes, and this is the part most teams miss. Watch the individual notice pages for bids you are working on as well as the listing page. Portals routinely revise scope and closing dates without notifying anyone who has not formally registered interest.
Hourly for new opportunities. Every fifteen minutes for a bid you are actively preparing, dropping to five minutes in the final week, when a deadline change is unrecoverable if missed.
No. If notices are only visible after signing in, a hosted change detector cannot reach them, and we will not ask for your credentials. This rules out a meaningful share of procurement, so check your key portals before subscribing.
Then it cannot be watched. Some portals produce results only after a form submission, with no stable address. Confirm that filtering changes the URL in your browser before setting this up.
25 on the $5 Founding Member plan, 10 on Basic, 50 on Growth and 100 on Pro, with one on the free plan. Watched pages have their own allowance, so they never consume your uptime monitors.
There is no check quota here. A plan gives you a number of watched pages and an interval, and the schedule runs indefinitely — so five-minute checking during a closing week costs exactly the same as hourly checking the rest of the year.
Yes. Paid plans send to multiple email addresses and to Slack, Teams, Discord, Telegram, Flock or a webhook. Team seats give colleagues their own login — 3 on the $5 plan, 10 on Growth, 25 on Pro.
Yes. Every recorded version keeps a full-page image and a word-level diff, and the last thirty versions of each watched page are retained. In a procurement dispute that record occasionally matters more than the alert did.
Reading published notices is what the portals exist for, and we request pages at a modest rate while identifying ourselves honestly. Some portals nonetheless restrict automated access in their terms — worth a look at the specific portals you depend on.
