SpeedTax says that much of the interest for its Internet-based sales-and-use tax system is coming from larger companies and that has led the Laguna Hills, Calif.-based vendor to enlist consultants that serve that market. “We've been driven or requested to move more up market,” says SpeedTax president Anton Donde, who continues that high-end consultants are making those requests because sales are drying up in the upper market. To make the move possible, SpeedTax has written an integration with SAP’s R3 platform.  Donde claims the feature set was already scalable and feature-rich enough to support large enterprises, but that SpeedTax lacked the channel that could serve them. Set-up fees, of course, will be higher and he estimated that fees for an SAP installation could be $30,000 or higher. Large end users will benefit from volume pricing since they will have a much larger transaction volume than mid-market users.
