Deltek and Grant Thornton form alliance


New strategic alliance between Deltek and Grant Thornton to support growing Deltek customer needs

HERNDON, VA – Deltek, the leading global provider of software and solutions for project-based businesses, has entered into a strategic alliance with Grant Thornton LLP, a leading professional services firm. The alliance will help both public and private companies of all sizes, including government contractors, to comply with accounting rules, regulations and standards using both technology and expertise.

Grant Thornton, itself a government contractor, will complement and extend Deltek’s Global Consulting capabilities – allowing the two companies to jointly deploy purpose-built, project-centric systems, including Deltek Enterprise Resource Planning, Project & Portfolio Management, and Talent Management solutions.

More specifically, Grant Thornton will provide Deltek’s customers with specialized know-how in systems integration, change management, finance optimization, digital transformation, compliance and business consulting. A broad range of Deltek clients that service the government stand to benefit from Grant Thornton’s specialization in government contract compliance – including professional-services companies, manufacturers, high-tech services companies and engineering firms.

“Government contractors can now tap into an integrated team that utilizes Deltek’s solutions and applies Grant Thornton’s acumen in transformation, change management and compliance,” said Greg Wallig, Grant Thornton’s Metro DC-Arlington office managing principal. “It’s important to have the best solutions and system integrators teamed together to provide clients with the highest-value transformation services.”

“Our alliance partners are a critical part of our ecosystem as a global business and we welcome Grant Thornton to that distinguished list,” added Matt Strazza, Senior Vice President of Global Sales at Deltek. “Grant Thornton understands the unique challenges that government contractors and project-based businesses face when looking to transform their business. As businesses change and grow, they need to adjust their systems and transform to maximize effectiveness. Together, Deltek and Grant Thornton will offer organizations world-class solutions and best practices to solve those issues and maximize the value of their Deltek investments.”
