how to update sales tax on an invoice

AI generated answer (using internal Slack threads):

To update the sales tax on an invoice in NetSuite, you can use the CSV import feature. This allows you to update multiple lines on a sales order at once. Here are the steps: 1. Create a saved search that includes the line number or line sequence number of the sales order lines you want to update. 2. Export the results of this saved search to a CSV file. 3. Update the tax code/tax rate in the CSV file for the lines you want to change. 4. Import the updated CSV file back into NetSuite. Please note that tax calculations are based on the document dates. Therefore, if you have a sales order that is fulfilled over a long period, the invoice will not necessarily follow the sales order to remain compliant with the tax rates in effect when the invoice is issued. If you're experiencing discrepancies between the tax calculations in NetSuite and another system like Shopify, it could be due to different tax calculation methods or rounding errors. In such cases, you might need to adjust the tax calculations in one or both systems to ensure they match. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
