Feature Request: Allow monthly billing

Received the following feature request from a partner

Add the ability to enable monthly billing

[mkilpatric]

We currently have over 500 customers who are on a monthly billing model, and would like to stay that way. With our store, we want to keep those customers on this model and not require them to order a license annually at this point.

Hi @IsaiahWilliams, I was just wondering if there has been any progress with adding monthly billing?

Otherwise, do you have any thoughts or advice about how this feature would be implemented?
