@Sue Bhuvan You can do the pre-billing part using the Included Quantity field on the usage item price plan, and combining it with a recurring or one-time item. The non-usage item is set to bill $10k. The usage is set to include the qty of usage that equals $10k, so no usage charges will be made until they have consumed the prepaid amount. The rev rec is a lot harder, though. Do you have other elements in the arrangement besides just the usage and prepayment?
