Sales Tax Directory Browser Vertex National Sales Tax Rate Directory Browser Vertex, Inc. has authorized R.O.I Syngineering to provide browser-based access to Vertex's National Sales Tax Rate Directory. This service is available on an annual subscription basis, only to current users of Vertex's electronic products.
Significant discounts are available to companies that require additional copies.
Our programs wrap HTML statements around Vertex's proprietary data, replicating the hardcopy version of the directory. Hypertext links simplify navigation around the directory using your standard Internet browser. And you can determine a jurisdiction's GeoCode merely by dragging your mouse pointer over the jurisdiction name. The GeoCode will be displayed in your browser's Status Bar - no need to refer to a separate manual. The added value of this service is manifested in several ways.
