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. We emphasize individual and collective excellence, continual innovation, and customer intimacy—while never losing sight of the importance of a fun and friendly work environment.

    I have been working at Vertex (Pennsylvania) full-time (More than 10 years)


    Vertex Inc is both an established and a growing organization. Next to its in-market and upcoming software products, which include its heavy-duty tax research groups and the data they provide, Vertex's biggest assets are its compassionate president and staff. You'll work your butt off, contributing to teams and to projects, learning all the time.


    Vertex Inc is not your kind of place to work if you want to be micro-managed, work in a vacuum, or want someone else to take responsibility for your work and your growth. Also, if you have the mind-set to climb a ladder, title by title, this isn't your place; there are not a lot of levels, title-wise, in most departments.
