I want to set a 9% mark-up on an invoice. how can I do this ?

AI generated answer (using internal Slack threads):

To set a 9% mark-up on an invoice in NetSuite, you can use a mark-up item. Here's how you can do it: 1. Navigate to the item list and create a new item. 2. Set the item type to 'Other Charge' or 'Service'. 3. In the 'Rate' field, enter 9%. 4. In the 'Income Account' field, select the appropriate account for tracking the mark-up income. 5. Save the item. Now, when creating an invoice, you can add this item to the line items. The system will automatically calculate the 9% mark-up based on the subtotal of the other items in the invoice. Please note that this method applies the mark-up to the entire invoice. If you need to apply the mark-up to specific items only, you may need to use a different approach or consider customizing your invoice form or using SuiteScript to automate the calculation. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
