Larry Ellison of Oracle (NASDAQ:ORCL), uber-consolidator of software, mentioned Siebel (NASDAQ:SEBL) on his short list for buyout candidates. Well, Siebel is not waiting to get taken out; rather, it is using its cash hoard to become a consolidator itself. Its latest move is the purchase of edocs for $115 million in cash (there may be additional payments if edocs hits certain milestones).

No doubt, Siebel needs a makeover. In the 1990s the company pioneered the market for customer relationship management (CRM) software solutions. However, Siebel now looks like a technology dinosaur compared with its fierce competitors, such as Salesforce.com (NYSE:CRM) and RightNowTechnologies (NASDAQ:RNOW).

edocs is a leader in eBilling and customer self-service software solutions -- collectively a $3 billion market that's been growing about 8% per year. The company allows companies to improve the quality of customer care, reduce costs, and build deeper customer relations. Customer service goes from expensive paper-based and call center channels to self-service approaches through the Internet and email. Customers include British Telecom, GE (NYSE:GE), and VerizonWireless (NYSE:VZ).

The deal comes at a cost for Siebel. It will mean a $0.01 drop in earnings per share in the first quarter of 2005.

All in all, edocs is a smart fit for Siebel. Unfortunately, it's more of a gradual empire expansion at a time when the company needs -- and investors want -- a rapid-growth injection. In the end, Ellison's suggestion to PeopleSoft (NASDAQ:PSFT) may extend to Siebel as well: The way to make shareholders happy is not by cutting small deals but by selling out.
