CHICAGO — Grant Thornton, one of America's largest brands of professionals providing end-to-end audit, assurance, tax and advisory services, has been named the Vertex Implementation Provider of the Year for 2026.
Vertex, Inc., a global provider of indirect tax technology solutions, honored Grant Thornton for its exceptional progress, creativity and impact in advancing risk mitigation through innovative indirect tax solutions. The award was presented at Vertex Exchange, a premier tax and technology conference, earlier this week.
Grant Thornton earned this recognition based on its longstanding collaboration with Vertex, commitment to client success and ability to deliver innovative tax technology solutions that help organizations modernize their indirect tax and compliance functions.
“This award reflects Grant Thornton’s commitment to helping clients navigate increasingly complex indirect tax and compliance requirements through innovation, industry expertise and a strong collaboration with Vertex,” said Rob Clarke, national managing partner of Global Indirect Tax services at Grant Thornton Advisors LLC. “Together, we help organizations modernize their tax operating models through integrated indirect tax, tax technology and e-invoicing solutions. By combining Vertex’s industry-leading platform with Grant Thornton’s implementation and transformation capabilities, clients can reduce risk, improve compliance and accelerate their digital transformation initiatives.”
Building on the success of its te.x platform, which uses AI and robotic process automation to streamline Vertex O Series implementations and ongoing maintenance, Grant Thornton has expanded its capabilities to support clients across the broader compliance lifecycle, including e-invoicing, continuous transaction controls (CTC) and global tax transformation initiatives. Together, Grant Thornton and Vertex assist organizations in establishing scalable, future-ready tax and compliance processes that drive efficiency, enhance visibility and support evolving regulatory requirements.
“This year’s winners have demonstrated what is possible when expertise, innovation and customer commitment come together,” said Chris Jones, chief commercial officer at Vertex. “Their ability to drive meaningful outcomes, solve complex challenges and help customers adapt to a rapidly evolving tax landscape has set them apart as trusted advisors and exceptional partners.”
