+This module adds several fields:
+
+* the *Supplier Payment Mode* and *Customer Payment Mode* on Partners,
+
+* the *Payment Mode* on Invoices.
+
+* the *Show bank account* on Payment Mode.
+
+* the *# of digits for customer bank account* on Payment Mode.
+
+* the *Bank account from journals* on Payment Mode.
+
+* the *Payment mode* on Invoices Analysis.
+
+On a Payment Order, in the wizard *Select Invoices to Pay*, the invoices will
+be filtered per Payment Mode.
+
+Allows to print in the invoice to which account number the payment
+(via SEPA direct debit) is going to be charged so the customer knows that
+information, but there are some customers that don't want that everyone
+looking at the invoice sees the full account number (and even GDPR can say a
+word about that), so that's the reason behind the several options.
