Thomson Reuters has announced the launch of QuickBooks Connexion from TaxConnex LLC. The Verified Integration provides businesses unified access to the industry-leading Thomson Reuters ONESOURCE Indirect Tax automation solution, enabling them to efficiently achieve sales tax compliance.

As part of the Thomson Reuters ONESOURCE Indirect Tax Development Partner Program, TaxConnex LLC worked closely with the Thomson Reuters team to design an application to extend the functionality of the Thomson Reuters ONESOURCE Indirect Tax platform to QuickBooks and joint TaxConnex LLC and Thomson Reuters customers.

“TaxConnex LLC’s Verified Integration demonstrates their commitment to our joint customers’ success,” said Tracy Mortenson, vice president of ONESOURCE Mid Market, Thomson Reuters. “Together, we are ensuring that corporations of all sizes have access to the most robust set of integrated tax tools, enabling them to stay compliant and plan for future growth.”

“Working with Thomson Reuters to bring their sales tax calculation solution to the small and mid-market business segment, and specifically to QuickBooks users, is a perfect fit with our strategy to serve this growing market segment,” said Brian Greer, Partners, TaxConnex.

TaxConnex LLC integrated solution achieved verification status by successfully completing the same rigorous Thomson Reuters testing process that Thomson Reuters products undergo to ensure effective functionality of the solution. The new integration enables TaxConnex LLC customers to seamlessly access ONESOURCE Determination and ONESOURCE Indirect Compliance to manage every process of the indirect tax life cycle.

TaxConnex LLC has provided the following feature set in their QuickBooks Connexion for QuickBooks:

  • Provides support for processing sales orders, estimates, invoices, and credit memos for the United States of America.
  • Enables QuickBooks users to access the power of Thomson Reuters ONESOURCE Determination.
  • Provides address validation to support accurate tax calculation.
  • Delivers presentation of tax in multiple formats include detail and summary level.
