The Hangar Management module provides features to manage office and hangar tenants and leases, and invoice current tenants. In addition, AVMAN tracks which tenants are not in the hangar and Transient Wait List is maintained so you can match up available space with requests from customers. Using an automatic invoicing system, office and hangar invoices are sent to customers for payment based on the terms and conditions of their lease agreement. These invoices are automatically forwarded to the accounts receivable and sales ledgers.
