Plans in Orb can now be configured with prices in a combination of custom credits and real-world currencies. The custom credits concept backs Orb's prepurchase ledger.

When configuring a plan, each price can be in either credits or the plan's invoicing currency. If the user subscribed to a mixed credits/currency plan and has pre-purchased credits, prices in credits will draw down from the pre-purchase balance, and any overage will be invoiced at the end of the billing period at the configured 'price per unit' rate for credits.
