Vertex Inc. ® Announces Validated Integration with Oracle’s PeopleSoft Enterprise 8.9

Vertex ® O Series ® Now Offers Seamless Integration With
PeopleSoft Enterprise 8.9 Financial Management

Berwyn , PA , February 14, 2006 – Vertex Inc., the leading provider of tax technology solutions, recently announced that Oracle has validated the integration of PeopleSoft Enterprise 8.9 with the Vertex O Series family of products. The integration includes PeopleSoft Enterprise 8.9 Financial Management; Payables and Enterprise 8.9 Supply Chain Management; order management, billing, and purchasing.

This validated integration between Vertex O Series and PeopleSoft provides customers with a solution that allows them to improve tax management efficiencies and compliance through one centralized system. They are able to verify vendor charged tax, automate accrual of consumer use tax, save time on month end reconciliation, and achieve more accurate sales and consumer use tax processing. By implementing Vertex O Series, tax professionals gain added control over tax decisions and obtain quicker access to enterprise level data for day-to-day operations and audit preparation and management.

The tools provided through the integration improve enterprise wide tax process visibility, which in turn will help today’s companies meet the requirements of Sarbanes-Oxley and its increased emphasis on reporting and corporate accountability.

“For over 15 years, joint customers have benefited from the strong partnership between Vertex and PeopleSoft. With the validation of this integration, Vertex continues its history of providing leading tax processing solutions to PeopleSoft customers,” said Jack Ferraioli, VP, Customer Relationship Development at Vertex.

About Vertex O Series

All Vertex O Series products for transactional taxes share the Transaction Processing System platform, which includes Vertex Sales Tax, Vertex Consumer Use Tax, and Vertex Value Added Tax. These products share common capabilities such as setup and maintenance tools, reporting functions, and an interface to your financial system.

All system functionality can be accessed through Vertex Central from a thin client using only a standard Internet browser. There is no system specific installation necessary for each user station. Handling all software upgrades and application installation through a central system server, reduces the overall cost of ownership for multi-user environments.
