Reverse auctions have gained popularity in the 1990s as a result of the emergence of Internet-based online auction tools. A pioneer of online reverse auctions, FreeMarkets was founded in 1995 by McKinney consultant and former General Electric executive Glen Meakem after failing to find internal support for the idea of ​​a GE reverse auction division. Meakem hired Mckinsey, a colleague Sam Kinney who developed much of the intellectual property behind FreeMarkets. Headquartered in Pittsburgh, PA, FreeMarkets built teams of market makers and commodity managers to manage the process of running the online bidding process and establishing market operations to manage global auctions.

The company's growth was greatly aided by the hype of the 'dot-com era.' Clients such as FreeMarkets (including BP plc, United Technologies, Visteon, HJ.Heinz), Phelps Dodge, Exxon Mobil, Shell and Royal Dutch Shell, to name a few, began competing by the dozens, while reverse auction service providers and established companies such as General Motors and SAP rushed to join the reverse auction market.

Although FreeMarkets survived the sell-off of the dot-com boom, by the 2000s it was clear that its business model was actually an old consulting economics company with some sophisticated software. Online reverse auctions became dominant and the prices that FreeMarkets had commanded for their services decreased significantly. This led to a consolidation of the reverse auction market. In January 2004, it announced above that it purchased FreeMarkets for $493 million.[1]​.

Fortune magazine "Fortune (magazine)" published an article in March 2000 describing the early days of reverse auctions.[2]​

In recent years mobile reverse auctions have evolved. Unlike business-to-business (B2B), mobile reverse auctions are business-to-consumer (B2C) and allow consumers to bid on products for pennies. The lowest bid wins.

Buyers, sellers and entrepreneurs must respect auction rules and sector codes of conduct for the use of reverse auctions, if they exist. Problems arise when one or more parties do not conform to the auction rules. This can range from simple complaints to litigation.

Buyers should not assume that savings are always achieved with reverse auctions on either a unit price or full cost basis. Reverse auction savings can range from negative (i.e., costing the buyer money) to neutral (i.e., no savings) to positive savings (10-20%, but the net savings is generally half that or less).

A true representation of savings cannot be achieved if unit pricing methods are used focusing on purchasing metrics such as purchase price variance, purchase order variance, or material price variance. Instead, cost savings have to be calculated, including direct and indirect losses associated with the use of actions to reverse the results of the reverse auction application, subsequent acquisitions, and related activities, such as returns of defective products or services, warranty expenses, litigation, etc.

Suppliers are advised to determine if there is a value proposition for them that justifies their participation.

Some have characterized reverse auctions as a technologically assisted form of negotiation that is receding with respect to the development of buyer-seller, collaboration, and purchasing relationships. The reverse auction has also been criticized as a method of lowering prices at the expense of quality – when one buyer uses a bid from suppliers to obtain lower prices than others.

Reverse auctions (also known as auction services) are currently experiencing a resurgence (9/2008), as evidenced by a number of auction sites for freelancers (e.g. eLance.com, guru.com, scriptLance.com) that are doing a significant volume of business both in large number of projects and amount of money spent (20,000 projects in the last 30 days and over $100 million spent since 2006 according to the eLance website). There are places within reach; such as those specializing in programming, technical writing, professional writing, desktop-based work (eLance.com, guru.com) or home improvement and construction, e.g. blauarbeit.de and eGenie.co.uk. Preserval introduced reverse auctioning to the industry's trading carbon credits.[3]​ A wide-ranging site, FlatDoor.com, covers all types of work anywhere in the world, including volunteer projects for nonprofit organizations.

A recent May 2007 article, Reverse Auctions – A Supplier's Survival Guide by Chafkin, cites Gartner studies as accurate. The same article quotes Sandy Jap, who studies reverse auctions at the Wharton School, estimating that up to half of all corporate spending could one day be decided by reverse auction.
