Why does tax change after I click Save in Netsuite?


You see the amount you expect for tax when working with an invoice in NetSuite, but when you click Save the tax amount changes and you want to know why.




  • In Edit mode NetSuite calculates tax with a flat % based on the subtotal of the invoice, no other information is factored in. 
  • When you click Save NetSuite  sends a call to the Avalara service, so the results change immediately, because it is only at that point that it is using our service and your Avalara Nexus, item mapping, tax codes, and tax rules are taken into account. 
  • Nexus must be added to the company and subsubsidiary before the sales order is created.
