I suggest ProcessMaker for Webuzo.
ProcessMaker is already in the works to be supported by Ampps/Softaculous so Webuzo should have it too but it will work through a workaround provided by the ProcessMaker team to resolve this problem "the install process of this script
requires modifications in the Apache configuration and the users on
serves do not have access to apache configuration".
This is a problem we should not have with Webuzo so i suggest processmaker support in webuzo the natural way without the mentionned workaround for a better use of the product.
