BISYS Group Inc. is expanding support for financial services companies that want to sell health savings accounts.

BISYS, Roseland, N.J., has introduced an HSA Service Center Web site service that resembles its existing individual retirement account service center Web site service, the company says.

The site can generate signature-ready HSA documents, BISYS says.

Companies can customize their sites, but BISYS will host the sites and update the content, BISYS says.
