Hello, what is the best way to get the tax to display/post on an invoice integrated into NetSuite when the tax is calculated in another system? We are trying to figure out the best way to do this. Thank you.

There are many options for this… For Tax Codes… use one default code, or setup tax tables in netsuite and have the netsuite tax engine select the appropriate code based on address, etc for tax amounts you can set whatever the external system calculated at the line or header level. Same for shipping tax.

can you set the tax amount field with a percentage?
