From paper-based tax reference manuals to Vertex Enterprise—the industry's first true tax management platform—Vertex has always maintained an unwavering commitment to Corporate Tax.

Ray Westphal purchased Vertex, a rate directory business, from Sorbus in 1978. Ray opened shop in rented space in Wayne, Pennsylvania, with his wife, Antoinette Westphal, joining as Vertex's first employee. By the early 1980s, the company was offering an expanded collection of products for managing transaction tax. In the late 1980s, Vertex rolled out National Sales Tax manuals, which included all general jurisdiction and products rules and regulations. The company also welcomed three Westphal children—Jeffrey, Stefanie, and Amanda—as employees.

Since then, Vertex has continually evolved to offer a full array of Corporate Tax technology solutions—all aimed at helping tax departments operate with greater efficiency, speed, accuracy, and strategic impact. From the very beginning, Vertex has retained our unique culture and values—among the reasons we've earned accolades for being an excellent place to work. We've also retained our focus on unleashing the strategic potential of Corporate Tax around the globe—with a clear vision to be the worldwide provider, partner, and employer of choice in the tax industry.

  • Our mission is to unleash the strategic potential of Corporate Tax worldwide
  • Our vision is to be the worldwide provider of choice, partner of choice, and employer of choice in the tax industry
  • Our values are founded in a commitment to and respect for people

Vertex operates with a unique corporate philosophy and a highly collaborative culture.

    I've been with the company for a little over a year; great work/life balance, reasonable timelines, super-nice people, and many folks are there for over 20 years. The CEO of the company is very down-to-earth and extremely likable. Huge inspiration.


    I guess some could argue that with a flat-lattice organization, there can be an adjustment period.
