Where BidSentry is a better fit
- HVAC shops that only chase federal work. It is built around SAM.gov HVAC notices (NAICS 238220) and nothing else, so there is no state or local noise to filter.
- Set-aside matching. You enter your certifications once (SDVOSB, VOSB, WOSB, EDWOSB, HUBZone, 8(a)); set-asides you don't qualify for stay out of your inbox, and if you're veteran-owned, bids reserved for you are marked.
- Fine-print flags. Each bid opens with a one-line flag for pending amendments, mandatory site visits and moved deadlines.
- Quiet inbox. It emails only when a new match posts or a deadline is close, and your first email lists every open HVAC bid in your area.
- Southwest federal HVAC. Its public state pages currently cover Arizona, New Mexico, Nevada, Texas and Utah.
Where IronBid Pro is a better fit
- You bid state and local work too. City, county, school district and state bids land in the same morning email as SAM.gov notices.
- You weld, fabricate or do millwright work. Those scopes are filtered in alongside HVAC.
- Price for a small shop. $29/mo or $199/yr compared with BidSentry's $79/mo ($49/mo while founding spots last).
- Price it fast. The built-in T&M rig estimator models labor, 1.5x overtime and materials markup.
