B2BQuoteTenders is one of the tools on I use a daily basis to find my opportunities. There are many aggregators out there, but this one has done me well over the last decade, the length of time I have been a paid-up user for.
There is plenty of competition, and I suggest you try a few – many, like B2BQuoteTenders, will give you a free trial so you can get a real taste for it before you commit any actual funds.
What I like about B2BQT is that it’s clean and simple, and I’ve found their lists to be fairly complete. Importantly, they don’t spam me with lots and lots of communications trying to up-sell me leads or workshops in tender writing, which my I experienced back when I was reviewing other portals.
So, definitely recommend, and for the right reasons – I myself am I paid-up member.
But also check out the competition, as they may offer services or functionality that suits you better.
