I appreciate your response.

I have found a stack of hosting resellers that offer me ordering services that can be integrated into my website.

I have also found numerous domain registrars that provide software and APIs that can be integrated into my website for me to resell domains.

My biggest question is how to "put the hosting and domain" all into one package - so my customers can do both at the same time when they'are at my website.

I want my customers to be able to signup for the hosting and domains in one shot - or do stuff seperately. How does someone like me (interested in starting up) setup something like this? Is modernbill the only way?
