As far as I can see AWBS is dead, I am now looking at;
wisecp | https://www.wisecp.com
clientexec | https://www.clientexec.com
blesta | https://www.blesta.com | Extensions - User Manual - Confluence
fossbilling | https://fossbilling.org | seems to have removed Virtualmin
billingserv | https://www.billingserv.com | does not seem to support Virtualmin
Has anybody got any experience using the ones that are compatible with Virtualmin?
I will be testing the 3 on a fresh install of Rocky to see how they intergrate and feel to use from both the Admin and customer experience and update.
