Cannot close Sales Order

What are the possible reasons as to why I can’t close an overdue Sales Order?

Hi @Gemma_Abra,

Maybe, If you’re unable to close an overdue sales order in ERPNext, it could be due to missing information, incomplete tasks, payment not received, stock unavailability, pending deliveries, or pending invoicing. Check for the specific issue and take necessary actions to resolve it.

Thank You!

Sales Invoice is not yet paid, and the customer returned 1 item so I created SI return. The billing status of overdue SO is not 100% and I was trying to close the SO since delivery for the items are already done.
