Procurement glossary

Sealed bid

A submission kept confidential and unopened until a fixed deadline, ensuring no bidder can see another's offer beforehand.

In depth

Sealed bidding protects procurement integrity: bids are timestamped and locked until the public opening, preventing collusion and late tampering. It is a cornerstone of fair public procurement.

How Bid.Guide helps

Bid.Guide submissions are sealed with tamper-evident timestamps and SHA-256 file hashes; nothing is opened before the deadline.
