does a sales order show as fully billed if the total amount is 0?

AI generated answer (using internal Slack threads):

Based on the conversations provided, it appears that NetSuite does allow transactions with a zero amount to be saved/created. These transactions will have a closed/paid in full/etc. status and you won't be able to apply it to anything. However, when it comes to billing $0 line items from Sales Orders along with other line items with amounts, there can be issues when creating custom billing schedules. The $0 line item will only be billed and put on the invoice if the custom billing schedule has an amount greater than 0 on it. If the custom billing schedule has a $0 value, it won’t even show on the invoice. In the case of a Sales Order of 4 quantity $0 amount, using a custom billing schedule with 4 recurrences each with $1 as the amount, the first one gets billed with the other line item (same custom billing schedule timeline just different amounts). But it bills all 4 together. If you need it to show on every invoice with the custom billing schedule, you may have to add it manually. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
