Is it possible to add a configuration in database to specify if we want the “only.” to appear after the conversion in words ?
Should we just remove the _('only.') ?
This is related to the way you normally write cheques, it’s basically so that it is obvious if people add extra words to the end. It is old-fashioned and not sure it’s really necessary on electronic/printed documents where the value is written multiple times anyway.
At the very least it should be the following to allow translation: _('only') + '.'
