New solution integrated to SAP Ariba cloud services helps businesses accurately and efficiently calculate and comply with global tax regulations for procurement and sales activities

Thomson Reuters has launched ONESOURCE Global Tax for SAP Ariba Solutions, a new offering to help companies using SAP Ariba cloud services to seamlessly calculate and comply with taxes associated with global procurement business transactions. Thomson Reuters ONESOURCE is an industry-leading global corporate tax technology platform that enables tax compliance and reporting in over 180 countries. Thomson Reuters is the first provider authorized by SAP to offer a tax calculation solution that can be connected to SAP Ariba solutions.

“Our global customer base has complex transaction tax requirements, and leveraging Thomson Reuters’ expertise in this area alongside our open platform, they can provide a powerful, yet easy-to-use solution that meets our customers’ needs,” said Dinesh Shahane, chief technology officer, SAP Ariba.

ONESOURCE Global Tax for SAP Ariba Solutions automatically updates country-specific taxation rules that change frequently. This ensures that SAP Ariba customers manage tax compliance against the latest tax regulations, saving companies time and costs by streamlining invoice reconciliation issues and eliminating errors resulting from manual and inaccurate tax rates and rules.

“Companies are obligated to calculate, track, and remit taxes properly when procuring goods and services for their businesses. Relying on vendor purchase orders, invoices, or estimates is not sufficient, and errors can put companies into a penalty situation,” explained Joe Harpaz, managing director for the Corporate segment of the Tax & Accounting business of Thomson Reuters. “We are very excited to be working with SAP Ariba to make tax simple for businesses that participate in the world’s largest marketplace of buyers and sellers by seamlessly integrating to support all facets of taxation accurately and on a global scale.”
