Is there anyway I can delete an item on an already created invoice, and not show the sales order as unfulfilled without having to manually close it out?
Hello there, @usap.
Let me help share some information about deleting an item from an invoice in QuickBooks Desktop.
In this case, you can open the invoice you've created and manually delete the item. Once done, mark the Sales Order as closed so it will not show as unfulfilled.
This will get you on the right track. Feel free to leave a comment below if you have another questions about the invoice for a sales order. Have a great day!
