Houston, Texas – May 20, 2008 — PROS, a world leader in pricing and revenue optimization science and software, today affirms key conclusions presented in the May 16, 2008 AMR Research Alert Article, “PROS Conference Reaffirms Strength of Pricing Application Market.”

Some of the key takeaways from this report include:

Pricing optimization projects implemented with real-time integrated science and a highly scalable product platform offer the greatest opportunity for profit improvement and a powerful return on investment. 

“One industrial manufacturer puts it like this: if the choice is between a pricing tool that can help demonstrate profitability to stakeholders or a multiyear ERP application with difficult-to-demonstrate, near-term ROI, the chances are executives will go for the pricing tool. At that manufacturer, price optimization was recently chosen as the top project to invest in by functional areas, including sales, marketing, and IT.” Source: Noha Tohamy, AMR Research, “PROS Conference Reaffirms Strength of Pricing Application Market.”

PROS price optimization software provides strategic innovation and risk mitigation in a challenging environment. “The natural reaction in a downturn is to retreat, cancel new initiatives, and go back to basics,” notes PROS President, Pricing Division, Jeff Robinson. “However, companies that focus on price optimization projects in this environment will be better positioned to remain profitable industry leaders as competitive opportunities arise and economics conditions improve.”

Innovative industry leaders choose PROS for best-of-breed science-based software products. “These tools must be able to conduct accurate customer and product segmentation while analyzing probability and the upside of customer retention as well as the cost to serve,” continues Noha Tohamy. “This is the only way for sales people to determine if transactions enhance the company’s overall profitability and its ability to achieve business goals.” 

In addition, tighter coupling of PROS’ Pricing Solutions Suite with Office Business Applications (OBAs), including Microsoft Office and Microsoft SharePoint provide an even more streamlined process. The largest consumers of price optimization data are sales executives. This added familiarity promises to offer even higher levels of adoption and ROI from an investment in pricing optimization software.
