I am currently taking over a business which is using WHMCS and CPANEL for hosting and I don't want to use this solution. The migration away from this system is going to take a while due to the complexities of the migration.
It appears that WHMCS has some useful automated jobs (mainly updating SSL Certificates), but is also doing periodic billing which I want to stop.
The version of WHMCS is v5.2.3 (Yes....)
Does anyone know how I can kill whatever it is that is scheduling and sending invoices?* (I assume its some cron job, but I have been unable to find sufficient information to identify what all the various cronjobs do, and nothing stands out). I'm very comfortable working at the command line and have root access if it makes any difference.
