+When invoicing multiple sale orders at the same time, they may be grouped into
+a single invoice. When it happens, it is hard to retrieve who the original SO
+partners were.
+
+This module helps by retrieving such partners and showing them into the invoice
+form view, alongside the invoice partner itself.
