A company that provides fund-raising software and services to some of the country's biggest charities is trying for the second time to fill its own coffers with an initial public offering, reports the Associated Press.

Convio, in Austin, Tex., expects to raise about $57.5-million in the share sale, according to its filing Monday with the Securities and Exchange Commission. The firm attempted to go public in 2007, filing for an initial public offering worth up to $86.3-million, but it withdrew the registration the following year.

The company's client list includes the American Cancer Society, the American Red Cross, Planned Parenthood, and the World Wildlife Fund. Convio lost $2.1-million last year, down from $3.7-million in 2008.
