Set a plan's credit grant to "Purchased" with a "Price per Credit", and it bills in advance as its own invoice line. A grant of 1,000 credits a month on an annual plan invoices as 12,000 × $1.00.

Pricing can be "Per credit: one rate" or "Tiered: rate changes with quantity", in volume or graduated mode, and tiered grants still invoice as one line at the effective rate. "Granted: included in the plan price" stays the default.
