I have some script pm my telegram codez123

Here is one for online network ads https://www.codester.com/items/6450/proads-online-advertising-network-script
Here is a very nice one for CPA  https://procpascript.com/ you can login to the admin panel and test it out. It is $99
You are looking for this one https://xyzscripts.com/solutions/cost-per-action-cpa-ad-network-script leave the full link or people won't know which script you mean. That costs $249 so I assume you looking to pay less. That is why I say the above is a good option.

This one is only $50 https://scriptgod.info/

I forget the name but there was a nice one for $75 it was the only one at that price so if you see one for $75 its probably the one I am thinking about.
Let us know how it goes.
