Sabrix and Thomson Tax & Accounting Team to Deliver End-to-End Solution for Sales and Use Tax Management

Sabrix Application Suite integrated with RIA's InSource Sales & Use Tax to provide complete sales and use tax solution for tax determination, calculation, recording, and filing

SAN RAMON, Calif. - December 9, 2003 — Sabrix, Inc. and Thomson Tax & Accounting's RIA Compliance business (RIA) announced today that the Sabrix Application Suite has been seamlessly integrated with RIA's industry-leading tax compliance software, InSource®. Sabrix is a leading provider of enterprise tax management applications, and RIA, a Thomson business, is the premier provider of technology and information solutions to tax professionals in accounting firms and corporations.

The seamless integration between Sabrix and InSource Sales & Use Tax software provides tax professionals in the U.S the most comprehensive and innovative tax automation and compliance solution available. Sales and use taxes that are determined, calculated, and recorded in the Sabrix application are automatically populated in the InSource software, eliminating costly manual processes and ensuring timeliness and greater accuracy in tax returns processing.

The Sabrix Application Suite, which has been implemented in Global 2000 corporations, seamlessly integrates with legacy financial applications and popular ERP systems to centralize tax determination for both domestic and international tax organizations. By providing the same seamless integration with InSource Sales & Use Tax, companies can initiate a financial transaction in legacy or ERP systems; have the Sabrix application provide all sales and use tax determination, calculation and reporting; and complete the tax filings with a direct connection to the InSource compliance software.

"Historically, tax professionals and their IT counterparts have had to piece together a number of products and supplement them with costly and time consuming manual processes in order to determine their taxes and file their returns," said Steve L. Adams, president and CEO of Sabrix. "When you combine the integration that we've done with RIA's premier compliance software and current Sabrix integration with financial applications, the tax business process is automated from end to end. Tax professionals as well as IT professionals are freed up to redirect their time and energy to more strategic tasks within their organizations."

"At RIA, we remain focused on enabling our corporate clients to leverage their investments in our tax compliance and filing software," said Brian Peccarelli, general manager for RIA Compliance. "By teaming with Sabrix, our enterprise-level customers have unprecedented visibility and control over their sales and use tax processes from the time the tax is determined to the time it is filed. Our customers also end up with a fully-reconciled compliance database for audit support and administration." As part of the Sabrix Application Suite, the connection to InSource Sales & Use Tax is included by Sabrix at no additional charge and is available immediately. InSource Sales & Use Tax is licensed separately from RIA Compliance.
