Sealed bid (Competitive sealed bidding)
Sealed bid stands for Competitive sealed bidding. A sealed bid is a price that stays private until a set date and time, when all bids are opened together. Paper bids come in sealed envelopes marked with the bid number. Electronic bids are locked in the portal until the closing time passes.
Competitive sealed bidding is the default method in most state procurement codes for purchases above a set dollar threshold. It keeps the process fair because no bidder can see or react to another bidder's price before the deadline.
Why it matters to a small contractor
Sealed bidding means a small company competes on equal terms with large ones. Your job is to get a complete bid in on time. Late bids are almost always rejected unopened, no matter the reason.
Example
A township accepts paper bids for a salt shed roof. A roofer hand-delivers a sealed envelope marked with the bid number and the words 'Sealed Bid, Do Not Open' to the clerk's office an hour before the deadline and gets a time-stamped receipt.
Sealed bid: common questions
What should be written on the outside of a sealed bid envelope?
Follow the solicitation, but it usually asks for the bid number, bid title, opening date, and your company name. If the envelope is not marked, it might be opened early or misrouted.
Does mailing my bid early protect me?
No. What counts is when the bid reaches the location named in the solicitation. Use a tracked courier or hand delivery, and leave extra time.
