Shipping cost are being removed from invoice

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like the issue of shipping cost being removed from the invoice or being invoiced incorrectly can be due to several reasons. One of the reasons could be that at the time of invoicing, the system inherits what is on the Sales Order (SO). If the shipping cost on the SO is incorrect, it will reflect on the invoice as well. Another reason could be related to the item fulfillment. If there are multiple item fulfillments with different shipping costs, it might cause the shipping cost on the invoice to be calculated incorrectly. In some cases, the shipping cost might be set to use a flat rate. If this is the case, the shipping cost on the invoice will be the flat rate, regardless of the actual shipping cost. To resolve these issues, you might need to use a script. For example, you could use a user event script that runs on the save of the fulfillment to check some boxes and ensure the correct amount is being charged for shipping. Also, if you want to bill only a percentage of the shipping cost on the first invoice of an SO, this would also need to be done with a script. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
