+This module allows to materialize an 'Early Payment Discount' from an
+invoice into a journal entry on a 'Miscellaneous' journal.
+
+As Early Payment Discount cannot be applied once an invoice is partially
+reconciled, the wizard allows to generate a journal entry using the full
+EPD amount.
+
+.. IMPORTANT::
+   This is an alpha version, the data model and design can change at any time without warning.
+   Only for development or testing purpose, do not use in production.
