Biddingo and MERX are both Canadian tender aggregators. MERX is widely used for larger public-sector competitions nationally. Biddingo lists many municipal and broader public opportunities and is part of the same wider bids ecosystem contractors already know. Alberta contractors still need Alberta Purchasing Connection plus Calgary and Edmonton city sites. Neither Biddingo nor MERX audits COR, WCB, or bonding.
Biddingo vs MERX for Alberta work
Use both if you bid beyond a single town. MERX shows up on larger provincial, MASH, and national packages. Biddingo is commonly used for municipal notices in various provinces. Overlap is incomplete — that fragmentation is why 'where are municipal tenders posted Alberta' has a long answer.
How do I register on Biddingo?
Create a supplier account on biddingo.com with your legal bidding name, then set location and category alerts. Complete the profile; empty profiles miss matching.
Do I pay for MERX or Biddingo?
Both offer account tiers that change over time. Some notices are visible with free/basic access; document packages and advanced alerts may require a paid plan. Check each site's current pricing. A $49.99 national alert product is a different vendor (TenderBridge) — it is not MERX and it is not a compliance audit.
The Alberta stack you actually need
APC + MERX + Biddingo + BidCentral/ConstructConnect + calgary.ca + edmonton.ca + individual town sites. Government tender alerts for contractors that cover only one of these will miss work. NorthCited's monitoring retainer is built for that stack, then filtered.
APC vs MERX
APC is the Alberta hub. MERX is the national board. Bid both profiles if you chase larger jobs.
Writing vs alerts
Innova Essential writes proposals. Portals host documents. NorthCited audits whether you can submit at all.
