Initiates billing for one-time and recurring products. It creates billing records when you pass order id and ReadyForBillingDate as parameter.

• One-Time Products: If you set both the price type and the billing frequency to One-Time, the API creates only one billing schedule record.
• Recurring Products: If you set the price type to Recurring and the billing frequency to Monthly, Quarterly, or Yearly, the API creates a cascade of billing schedule records, depending on the selling term.
