Every tender, the day it posts.

Most tenders are lost before anyone writes a word, because the team that wins found it first. Procurement portals don't notify you: listings post with two-week windows, deadlines move in amendment PDFs, and award notices appear without ceremony. Checking five portals every morning is somebody's least favorite job.

modsignal makes it nobody's job. Point a monitor at each portal's listing page and describe your niche in plain language — alert me on new tenders mentioning fleet management or vehicle tracking — and it reads new listings against your prompt, not against a keyword list that misses every synonym.

When something matches, the alert gives you the title, what's being asked for, and the deadline, so bid/no-bid takes one read. Deadline and amendment changes on a specific tender are worth their own exact-diff monitor — on a single tender page you want to know about every edit, verbatim, instantly.

Bid teams usually run one semantic monitor per portal for discovery, plus an exact-diff monitor per live pursuit. Check portals daily — most post during business hours — and pursuits hourly as the deadline approaches.
