are Matrix Items available to all accounts OR only with the advanced inventory add-on

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that Matrix Items are not available to all accounts by default. They are part of the Advanced Inventory Module, which is an add-on in NetSuite. This means that you would need to purchase this add-on to enable Matrix Items in your account. Please note that you should be clear about your requirements before purchasing the add-on, as there can be some confusion with the naming of different features. You can check whether you have the Advanced Inventory Module under Setup > Company > View Billing Information (Add-On Modules tab). If you don't have it, you would need to reach out to your account manager to purchase it. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
