Nothing as such, however our support was excellent at every step of project implementation & training them for their continued use in future projects would have been nice! The ease by which we can deploy new features/products - this has now become easy thanks solely due its integration into JIRA (Bug tracking system) along wth it's ability integrate seamlessly within existing applications like Sage 300 ERP etc makes us feel really good about having chosen mavento commerce over other platforms out there!!
