NetSuite's SuiteTax determines US sales tax on transactions, through its SuiteTax Engine or a partner tax engine, and the U.S. Sales Tax Reports SuiteApp adds liability and by-state reports.

Where it stops

Filing is handed off: for returns, the reports SuiteApp has you select a third-party tax filing partner.

What Kintsugi adds

Kintsugi covers the whole job. Its Vertex-powered engine calculates sales tax on NetSuite invoices in real time, and Kintsugi monitors nexus in every state, then registers, files, and remits for you.
