AvaTax On-Demand

(Link to Article)
AvaTax On-Demand calculates sales and use taxes for any of the 8,000 U.S. taxing jurisdictions and enters the results into a user's accounting system.

The application comes with a Web software development kit whose adaptor integrates AvaTax with e-commerce, third-party, or custom-built ERP systems. AvaTax On-Demand integrates out of the box with Sage's MAS 90/200, the Accpac Advantage Series, and Great Plains. The adaptor in the SDK lets developers working in .Net or .Com-compliant languages eliminate the need to build, read, or transform data into SOAP messaging.
