Most government and public owned companies goto tender. Not sure how it is in Ontario... But over here that means most are out on bcbid or goto queens printers who send stuff out to specific companies to be bid on.
I believe BC bid is like $100 a month... Then some of the bigger contracts have a $100 bid fee.
Not just that.. but a few tenders we've done for the government requires you to put a deposit down that's worth 25% of the job.... One job we won for $60,000 to redo a pier with all new signange and wraps required us to give them a cheque worth 15k... And we got no payment or anything until it was done.
It's a way to make sure smaller companies don't bid on stuff they can't handle, finish a quarter of the job and then walk away from it.
We do a lot of bid sites as most of our work is government and larger jobs. I can say they don't always go for the lowest dollar bids, we've been 30% higher and still got the job. But we've been doing it for 25+ years and most of the companies are ones we've worked with before.
They can be lucrative... And you may just need to stick with it for longer and be picky on which ones you bid on so you're not wasting time. All you need is one job and the fees for the year are paid for.
Now on the other hand. We do 90% of the work for a utility company here. But they're publically owned so everything has to be tendered... Everything. There was a 10 page bid, about 10 forms to submit.... An hour's worth of work easily... For a single, $10 item. We still did it because of who it was... But the fact that they had to put it on a bid site was ridiculous. Jumping through hoops to produce a single decal....
So bid sites can be good, and they can be bad. Once you become established by all the purchasers of the repeat companies and get your foot in the door, it can be worth it. We usually go in a little cheaper for new companies / purchasers and slowly creep the price up to where it should be on following jobs just to get our foot in the door.
How close are you to Perth? We just completed 20,000 street signs by winning the job on a bid site! Which is another great thing... We can bid on jobs 2000 miles away because of bid sites.
