Thank You for Purchasing. Because I have a few services that can be automated after purchasing, if I can properly send them there after the purchase. Examples would be ESN Change, or Activation.

In core zencart, it's possible (on checkout_success page) to activate a PLEASE NOTIFY ME function, where the NOTIFY relates to products the customer has just ordered.
So it would appear that it is possible to create product-specific messages on that page, that are depandant on what was in the final order.
It would seem logical then, to go look at the code that drives that function, and see if it can be modified to call in your info.
You would NOT create separate php files - just insert code that introduces conditional statements (EG: IF xxxxxxx HAPPENS, THEN DO yyyyyyyy).
