Ryan Announces Issuance of United States Patent for Dynamic, Rule-Based, Tax Decision System

Press Release Nov 09, 2010

Dallas, Texas – Ryan, the leading tax services firm in North America, with the largest transaction tax practice in the United States and Canada, today announced that the United States Patent and Trademark Office has issued United States Patent 7,739,160 B1 relating to its dynamic rule-based tax decision system, known as TaxDecisionERP®.

TaxDecisionERP® is an integrated solution and methodology for Enterprise Resource Planning (ERP) systems (such as SAP®), which enhances tax determination integration decisions when using third-party tax calculation software. This enables companies to minimize tax decision errors while calculating tax payments on actual use rather than at purchase time, eliminating the labor associated with manually calculating and correcting use tax. TaxDecisionERP® also provides tax calculations as goods are issued and contract labor hours are recorded, providing finance professionals visibility and controls for improving their bottom line. The solution also greatly enhances the audit and traceability tools critical for Sarbanes-Oxley documentation and control.

"This patent represents another important milestone in Ryan’s mission and vision of providing the most innovative approach to tax consulting available in the market today," said G. Brint Ryan, CEO and Managing Principal of Ryan. "It exemplifies our ability to develop innovative solutions that anticipate and respond to the challenges facing tax and finance executives worldwide, and protect our intellectual property for the benefit of our valued clients."
