The property receivable module of the REO/Relocation Billing System provides all the functions necessary to process receivables activity for all the properties you manage.
It tracks all expenses incurred for the properties. These are automatically posted to the properties from the Accounts Payable module when you pay you vendor's bills.
This module lets you print invoices to all the 3rd party companies for the expenses you incurred during the month. It also tracks all the payments received from the 3rd party companies you bill.
Put these functions together and you have a complete picture of each of the properties you manage.
