Fees Configuration

Fees is a great add-on, however, it is very limiting in the conditions. For example, if one wanted to create a pro-forma invoice (or an invoice) for installation which may need to be paid upfront for certain tariffs, there is no option to select a different trigger, for example if the tariff is “x” on conversion from Lead to Customer, create invoice. In short, it would be great if there were more trigger options available.
