****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** Based on the conversations, it seems like the issue of double invoicing after a NetSuite update could be due to a variety of factors. Here are some potential causes and solutions: 1. Accounting Errors: If there is a debit and credit to the same account, it can result in strange errors. Make sure to double-check your accounting entries. 2. Tax and Shipping Items: Ensure that the tax and shipping items are correctly set up. Any discrepancies here could lead to double invoicing. 3. Consolidated Invoice Add-On: NetSuite has a consolidated invoice add-on that might help with your issue. It was released a few years ago and is now a free bundle, but you need to contact your account manager to provision it in your account. If the issue persists, you might need to involve your IT department or consider scripting a custom solution using custom records, suitelet, and advanced PDF template. However, this should be a last resort after you've exhausted all other options.
