NetSuite shares rose $3.12, or 15 percent, to close at $24.12, in New York Stock Exchange trading.
The company sells a suite of software programs that small and mid-size companies can access over the Web. They cover tasks from accounting to sales and marketing and Web commerce.
Mark Schappel, a financial analyst with Benchmark Co., said he saw a demonstration of the product last week.
He said one significant addition to the suite is software that allows companies to "slice and dice" data on business transactions, providing valuable information on how the business is going throughout the course of each reporting period.
"It's a great product," he added. "But it's an incremental addition from what they already had."
