Enable payment for tracking running own server??

I have searched for this answer and for some odd reason I can find zero results... I would have thought its a thing! :-)

Thanks!

There's a bunch of discussions and questions about it. Surprised you haven't found any. For example:

https://github.com/traccar/traccar/issues/3296
https://www.traccar.org/forums/topic/any-idea-about-integration-with-a-billing-module/
https://www.traccar.org/forums/topic/traccar-whmcs/

And this module should be a working solution in combination with whmcs

Does anyone have a working link to this module
