How do I uninstall the ISPConfig 3 billing module?

Hi there,
I trust you are well.
I am wanting to remove proprietary software from my services. I installed the Billing module on one of my ISPConfig instances.
How do I correctly uninstall the software?

 

Same question here. I don't need it any more and it prevents old users from being deleted.

 

Bumping this because I went through a deletion process, but I was not able to delete customer accounts afterwards either. The process I followed is as follows:

"Take a look inside the billing module zip archive, there you find a folder 'interface' and a folder 'server', these correspond to the folders with the same name that you find in /usr/local/ispconfig/ on your system. The removal would be to delete all files that you find in the zip file projected to /usr/local/ispconfig/. After removal of the files, remove all invoice* tables inside the dbispconfig database."

 

Thanks to both of you. I did the following:

1. Deleted the files billing_plugin.inc.php and sepa_plugin.inc.php from /usr/local/ispconfig/interface/lib/plugins
2. Deleted the tables invoice* from the dbispconfig database.

This still brings up the billing module in the ISPConfig start page but I don't care. It allowed me to remove all the old clients and other stuff that I wanted to purge.
