You want to know how to disable locations in Netsuite.
- Navigate to Avalara > Setup > Configure AvaTax
- Go to the Tax Calculation tab
- Place a checkmark in the 'Disable Location Code' checkbox
- Press the Save button
Note: The location in NetSuite is used as the origin address by default in NetSuite. This means AvaTax reads either the header level location field, or line level location field if present, and uses it for tax calculation. Some businesses do not associate addresses with their locations, or use addresses not associated with the origin of a transaction and wish for the company's main address to be used as the origin, so turning off locations is necessary to calculate tax with a custom address.
