Custom billing cycles
I would like to have a customisable billing cycles where the administrator can determine the length of the cycle in days, weeks, months or years. Why?
I resell SSL certificates in a country heavily beaten by the crisis. I don't feel it is ethical that I must charge yearly when the certificate has a validity of one and a quarter year. I'm sure there are others that would want to add cycles that are not in the fixed periods that WHMCS offers us.
When the feature is also added to the API then third-party modules can create billing cycles according to their products.
