Charge Vendor Subscription Fee to Become a Vendor
Become a Vendor for a certain price per term (year, month, day...etc...).
An integration across the subscriptions module and the Vendors module whereby the Vendors would pay a subscription. In our case Vendors would pay yearly, unless they already sold enough then we would not charge them the subscriptions fee.
Id est...A vendor pays $10 / year....if the Vendor sells then our store takes a commission. If a Vendor sells enough for us to make more than $10 / year from commissions then we do not charge them the subscription fee.
