Create unique individual invoices?

I'm new to CB and CB Subs so I don't know if I can do what I need to for my business or not? My business provides monthly subscriptions which is no problem for CB Subs, but we also provide individual services where the price can vary tremendously. I was wanting to know if there is any way I can just create a new unique invoice for an individuals services through CB Subs without them having a subscription?

You can create as many plans as you want of type Subscription, Merchant, and Donation as well as have whatever prices you want. You can not issue invoices to be paid of any amount you want. CBSubs is a subscription management system first and foremost; it is not an invoice system.
