SUNNYVALE, Calif. -- Ariba(R), Inc. (Nasdaq:ARBA), the leading spend management solutions provider, today announced that it has been recognized as the Best Electronic Bill Presentment and Payment Services Provider by Global Finance Magazine as part of its annual ranking of the Best Treasury and Cash Management Banks and Providers. Ariba was selected for the award on the basis of its market leadership, customer service, competitive pricing and innovative technologies.

"Our awards identify the providers that consistently improve transaction processes to speed collections and reduce risks."

Ariba offers a comprehensive range of invoice and payment solutions that enable companies to develop and implement a highly integrated cash management strategy while improving the efficiency of the entire procure-to-pay cycle. Ariba's Electronic Invoice Presentment and Payment(TM) and the Ariba Supplier Network(TM) effectively enable companies to optimize their invoicing and reconciliation processes and has helped to generate measurable and sustainable results for many organizations, including:

--Reduction of paper invoicing volume by more than 60 percent.

--Decrease in PO-Invoice error rates by over 50 percent.

--Trimming of invoice & payment cycle times by 75 percent.

--Capture of negotiated and early-pay discounts otherwise lost to manual processes.

--Bulk enablement of several thousand suppliers in months rather than years.

"When it comes to effectively managing cash, the automation of paper-intensive tasks such as invoicing and payment is critical," said Chris Eyerman, Director, Connectivity Solutions, Ariba. "But to generate savings that are both measurable and sustainable, companies must also automate supplier interactions to achieve efficiency and accuracy throughout the procure-to-pay cycle. Our solutions are uniquely designed to help companies do both and accelerate the results that they achieve."
