Internal Billing

Internal Billing captures transactions that occur when two departments exchange goods or services. This module replaces Internal Paper requisitions and the Service Center Lien System. Internal Billing can record one-time-only requisitions as well as blanket requisitions.

Overview of Internal Billing Process

The receiver of a service uses an eDoc to initiate an internal billing request with a predefined amount (and optional pre-defined overage amount). The service center receives the eDoc for review and approval. A lien is created on the department account upon service center approval. After rendering the service, the service center can use Internal Billing Journal Vouchers to relieve the lien and to charge the department. The Internal Billing Journal Voucher is designed to operate like a General Journal Voucher. Service Center numbers are derived from the Journal Voucher numbers.
