The Eighteenth Microsoft Convergence features a phenomenon not seen in several years—the four major sales tax vendors had exhibits. Avalara and CCH have not missed a show with their booths, although the size and location of the CCH presence has fluctuated widely. This year, Vertex and Taxware were on the Convergence floor for the first time in a long time. CCH also had a bit of a change with its new booth which emphasizes the company as a unit of Wolters Kluwer.
