why sales orders with zero cost are not automatically being billed or stays pending billing

AI generated answer (using internal Slack threads):

Sales orders with zero cost might not be automatically billed or stay pending billing due to several reasons: 1. Billing Schedule: If the billing schedule for the sales order line is set to zero or a custom schedule that doesn't trigger billing, the sales order will not be billed. 2. Line Status: If the line item on the sales order is not closed, it may prevent the sales order from being billed. Closing the line item might resolve this issue. 3. Intraday Transactions Mis-Order: If the intraday transactions are mis-ordered, NetSuite might think that you shipped out the item before you received it. This could result in a zero unit cost. Adjusting the receipt date and recalculating the costing might fix this issue. Please note that these are potential reasons and the exact cause might vary based on the specific configuration and setup of your NetSuite account. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
