Sealed bidding
A bid process your board can defend.
Locked until the deadline
Nobody sees a price or a document before the due date: not you, not other bidders, not BidPost staff.
All bids open at once
At the due date every bid unlocks together, so nobody gets a head start.
Tamper-evident receipts
Each bid gets a receipt code computed from its price, notes and files. When bids open, BidPost checks that nothing changed.
One answer for everyone
Questions & updates go to every bidder, so all bids price the same work. Due dates can only be extended, never cut short.

Side-by-side comparison
See why one bid costs more than another.
When bids open, AI reads every proposal and its documents and lines them up, so you compare what's included, not just the totals. It never picks a winner; you do.
Example: replace a 400 sq ft deck with composite decking. Sample bids for illustration.
| Item | Contractor A | Contractor B | Contractor C |
|---|---|---|---|
| Price | $13,900 | $15,400 | $17,200 |
| Decking | Composite, entry line | Composite, mid line | Composite, mid line |
| Railing | Reuses existing | New wood | New aluminum |
| Permit | Not included | Included | Included |
| Tear-off & disposal | Included | Included | Included |
| Timeline | 3 weeks | 2 weeks | 2 weeks |
| Labor warranty | 1 year | 2 years | 5 years |
✨ Why the prices differ
C costs $3,300 more than A, but includes the permit, new aluminum railing and a five-year labor warranty. A reuses the old railing and leaves the permit to you.
✨ Questions to ask before you award
- Contractor A: what would the permit and new railing add?
- Contractor B: which composite line, and what does its warranty cover?

Trust and verification
What our badges mean, and what they don't.
- Your contact details stay private: phone and email are shown only to verified contractors.
- We never keep tax IDs: an EIN is checked once and only its last four digits are saved.
- AI features: listing text, insurance certificates and bid documents are processed by Anthropic to power them.
- BidPost isn't a party to your contract and doesn't guarantee anyone's work.
| What's checked | Gray | Blue | Gold |
|---|---|---|---|
| Email and phone number confirmed | ✓ | ✓ | ✓ |
| Owner's ID checked (sole proprietors) or state registration and EIN checked (businesses) | – | ✓ | ✓ |
| Current certificate of general liability insurance reviewed (AI and our team) | – | – | ✓ |
Not checked by any badge
Contractor licenses, workers' compensation, bonding, the quality of past work, or whether insurance limits fit your project. Ask for these before you hire.
