I run a free hosting for game servers and I need a special addon to be made for the billing panel.So the panel will renew the service every month automatically and I want to have an addon that will change that.here's how it would work after a user rents a server there will be a time in this format(day) : (hour) : (minute) : (second) and there will be a button next to it called restart it would restart the timer back to 30 days or 30 : 00 : 00 : 00 then if it hits 00:00:00:00 an email will be sent saying the service is suspended and they need to hit renew. the grace time would be 5 days in suspended more after that the server gets terminated. also, an email gets sent after each stage (active, suspended, terminated,)
