IronBid Pro vs BidFox: Federal-Only Ranked Alerts or a Federal + State Trade Digest?
BidFox (getbidfox.com) reads every notice posted on SAM.gov each morning and emails a ranked list for your trade and states. Its own comparison page says it covers federal contracts only. IronBid Pro is a daily 7:00 AM ET digest that covers federal, state and local bids for welding, structural steel, fabrication, millwright and commercial HVAC/boiler shops, with a T&M rig estimator built in. Both start at $29/mo. If you only bid federal work, BidFox is a solid pick. If you also bid city, county, school, airport or state DOT work, IronBid Pro puts it in the same email.

Where BidFox is a good fit
- Federal-only bidders. It says it reads every SAM.gov notice each morning and ranks them for your trade and states.
- Many trades. It covers trades outside welding and HVAC, such as electrical, janitorial and IT.
- Clear ranking. It publishes how a notice earns its score.
- Try before paying. A free sample alert, then 7 free days on either plan.
Where IronBid Pro is a better fit
- You bid state and local work. A lot of welding and boiler work is posted by cities, counties, schools, airports and state DOTs rather than on SAM.gov, and BidFox says it does not cover those bids.
- You weld, fabricate or do millwright work. The digest is filtered for those scopes, not every trade.
- Annual option. $199/yr works out to about $16.58/mo; BidFox bills monthly.
- Price it fast. The built-in T&M rig estimator models labor, 1.5x overtime and materials markup.
