Using the Sales and Use Tax Interface > Introduction
  
Introduction
The Sales and Use Tax Interface (SUTI) is an application programming interface (API) designed for companies that use QAD’s ERP application, and need advanced tax rate and tax calculation solutions offered by companies like Vertex.
SUTI works in conjunction with GTM and Quantum to retrieve tax jurisdiction information from the Quantum system and calculate US and Canadian regional taxes using Quantum calculation rules and tables.
For complete information on setting up and using GTM, see User Guide: QAD Global Tax Management.
