+Invoices Reference
+==================
+
+Aims to simplify the "references" things on the invoices.
+There is too many fields on the invoices.  And it is very difficult
+to remember which field goes in which field of the Journal Entries.
+
+It particularly fits with other modules of the bank-statement-reconcile series
+as account_advanced_reconcile_transaction_ref.
+
+Use cases
+---------
+
+Customer invoices
+  Journal Entry Reference is the Origin of the invoice if there,
+  otherwise, it is the Number of the invoice.
+
+Supplier invoices
+  Journal Entry Reference is the Supplier Invoice Number of the invoice
+  which is now mandatory.
