Bidder

Bidding is an offer (often competitive) to set a price by an individual or business for a product or service or a demand that something be done. Bidding is used to determine the cost or value of something.

Bidding can be performed by a "buyer" or "supplier" of a product or service based on the context of the situation. In the context of auctions, , or real estate the price offer a business or individual is willing to pay is called a bid. In the context of corporate or government procurement initiatives, the price offer a business or individual is willing to sell is also called a bid. The term "bidding" is also used when placing a bet in card games. Bidding is used by various economic niches for determining the demand and hence the value of the article or property, in today's world of advanced technology, the Internet is a favored platform for providing bidding facilities; it is a natural way of determining the price of a commodity in a free market economy.

Many similar terms that may or may not use the similar concept have been evolved in the recent past in connection to bidding, such as reverse auction, social bidding, or many other game-class ideas that promote them selves as bidding. Bidding is also sometimes used as ethical gambling in which the prize money is not determined solely by luck but also by the total demand that the prize has attracted towards itself.

Bidding performs in two ways online: unique bidding and dynamic bidding.

Unique bidding: In this scheme, the user who gives the most unique bid wins the bidding. For example, if users A, B, C, D, and E are bidding for the same product, and A bids $5, B bids $5, C and D bid $2, and E bids $3, then E wins the bidding because his bid was unique.

Dynamic bidding: This is a type of bidding where one user can set his bid for the product. Whether the user is present or not for the bidding, the bidding will automatically increase up to his defined amount. After reaching his bid value, the bidding stops from his side.

Timed bidding auctions allow users to bid at any time during a defined time period, simply by entering a maximum bid. Timed auctions take place without an auctioneer calling the sale, so bidders don't have to wait for a lot to be called. This means that a bidder doesn't have to keep his eye on a live auction at a specific time.

By entering a maximum bid, a user is indicating the highest he is willing to pay for a lot. An automated bidding service will bid on his behalf to ensure that he meets the reserve price, or that he always stays in the lead, up to his maximum bid. If someone else has placed a bid that is higher than the maximum bid, the bidder will be notified, allowing he to change the maximum bid and stay in the auction. At the end of the auction, whoever's maximum bid is the most wins the lot.
