why im i seeing my sales order status go from billed to pending billing ?

AI generated answer (using internal Slack threads):

The status of a Sales Order (SO) in NetSuite can change from 'Billed' to 'Pending Billing' due to several reasons: 1. Line Items Not Fully Billed: If all the line items in the SO are not fully billed, the status can revert to 'Pending Billing'. This can happen if some items were removed from the invoice and then manually re-added. You can verify this by clicking on 'Bill' on the SO and checking if all items are listed. 2. Partial Shipment: If the SO was partially shipped and billed, it would also make sense why it's in 'Pending Billing'. Even if the total amount of the invoice matches the SO, if not all items have been shipped, the status will remain 'Pending Billing'. 3. Dropship Orders: For dropship orders, the status can remain 'Pending Billing' until the Purchase Order (PO), Item Fulfillment, and Invoice are all fully shipped/billed. To resolve this issue, you can: - Ensure all line items are fully billed and shipped. - Close the order or use the line level close if all items are billed and shipped. Remember to always check the line items and their status when dealing with SO status issues. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
