Sealed Bid (also known as Blind Bid, Negotiated Sale, or Private Treaty) auctions are a type of sale where bidders cannot see what others have bid.
You can run a sealed bid auction in BidJS by using a combination of specific settings at both the item and auction levels.
This guide covers:
Creating the Auction and Items
Extra Options
Accepting and Rejecting Offers
Creating the Auction and Items
Create a Timed Auction.
Create items of type Listing.
3. Select the Purchase Option of Make_Offer.
Your item will appear to the public like this:
Extra Options
Purchase Price:
Automatically rejects offers made below the specified price.
Display Price:
Shows as an Opening Bid amount to users.
Has no effect on bidding unless a purchase price is also set.
⚠️ You cannot sell multiple quantities with this type of item/purchase option.
Entering a value in the Quantity field will return an error.
This field must be left blank.
Accepting and Rejecting Offers
By default, each user can place up to 3 offers per item (including those that are automatically rejected).
This limit can only be changed at the system level and would affect all clients on the server.
You can accept or reject offers at any time—whether the listing is live or has ended.
⚠️ Once an offer is accepted, you may see Number of Bids = 0 depending on your settings. This occurs if:
The "Show Number of Bids" setting is turned on at the auctioneer level
The item is still live or has ended, but the auction itself is still live
