Software: Intuit QuickBooks accounting software
QuickBooks allows you to consolidate multiple Sales Orders into one Invoice.
Sales Order is used to track the orders from customers, backorders, and some users may also have used the Sales Order to track the consignment goods to customers. When the customer name is being picked up in the invoice, a list of Sales Order under the customer name will be listed. User can pick up the relevant Sales Order(s) and opt whether to invoice in full or selected items from the Sales Order(s).
The Sales Order number, which tagged next to the item, helps finding the relevant Sales Order if a discrepancy arise.
