Receivables Exchange said Wednesday that it is working with Insperity to provide live receivables auctions to more small and medium U.S. businesses.

Launched in 2007, Receivables Exchange allows companies to sell their receivables to a network of institutional investors through a live auction. This provides sellers with access to working capital quickly while buyers typically purchase the debt for less than its face value and make a profit when the notes are fully paid.

Under the deal, Insperity made a capital investment in the Receivables Exchange. However, this investment will not be material to Insperity's 2011 results. Other financial terms of the deal were not disclosed.

The deal expands Receivables Exchange's reach to more than 100,000 businesses supported by Insperity, a company that provides human resources and business performance solutions.

"Access to capital is the lifeblood of any business, and we are pleased to be able to offer the Receivables Exchange's innovative financial solution to our clients and other small and medium-sized businesses," said Paul J. Sarvadi, Insperity chairman and chief executive, in a news release. "This joint venture complements our comprehensive array of human resources and business performance solutions designed to help companies run better, grow faster and make more money."

The Receivables Exchange previously integrated its receivables trading platform with the Ariba Network platform operated by Ariba Inc.
