Invoice Verification and Billing in Agency Business 
As soon as the lessor receives an invoice from a service provider for a service, it:
Checks the invoice
Bills the lessee if the service is not covered by the lease
The lessor can use agency business (LO-AB) to bill the lessee for the invoiced amount. The lessor can also combine lease installment payments, fees, and so on, in one invoice for the lessee.
