I was trying to build a similar platform like DM Champ, than i saw it on Appsumo and thought wow, what i'm trying to build is already built and in years further in stage. Instead of developing my own system i use DM Champ. It works perfect and has everything i need for my clients. Lots of documentations and instructions and helpful developers who implement fixes ASAP i can only say good words about this platform. if you have missed the deal and you are searching for a follow up ? This is the tool you need. Buy an unlimited plan because it's worth it if you are serious.
