I'm working on a website that deals with charging customers a membership amount with either a monthly or annual billingy cycle. There will also be various one-time type fees for certain features or changes that is made to their account.
I really only have experience with ecommerce type shopping carts (osCommerce), where orders are submitted and processed from mainly the admin orders section of the website...which is pretty straight forward.
However, I never had any experience on what the best way to handle a website that deals with memberships (monthly / annualy) or charging customers different types of fees based on certain features or account changes. I don't know what the best way to handle or set this up in admin this way I can process everything properly.
Does anyone know if there are any shopping carts or websites that offer a feature like this to handle memberships/fees charges? And if they have a demo of the admin site this way I can get an idea of how I should set this up on my website?
