One Line Invoice
Please consider allowing single line invoices.
For example, we often Quote qty. 5 items to a customer. They accept the Quote and return a single line Purchase Order. This customer PO then allows us to authorize the Quote, release Production Orders and process the MOs.
Once shipped, we need to Invoice the Sale as a single line item, matching their single line PO. A single line invoice option would solve this common issue for us. At this time, it requires us to Invoice outside of DEAR.
