Why $9?— and why not free?

Because someone has to go get them.

Every day we sweep thousands of federal, state, and local sources, then clean, categorize, and summarize what we find — so you spend your evenings running your business, not refreshing portals. Servers, research, and upkeep cost real money, every single day.

Because you shouldn't be the product.

We could make this “free” with ads, or by selling your data. Then we'd be working for advertisers instead of for you. We run no ads and sell nothing about you — the only people we answer to are the members paying $9.

Because $9 is the honest number.

The price of one coffee a month, and it's the same for everyone — no enterprise tiers, no sales calls, no annual lock-in. Win a single contract here and it has paid for itself many times over.

Thank you for keeping an independent, ad-free bid platform alive. 💛— the BiddingSimple team
