Once you have established a cost for a specific transaction; purchase, sale, refinance, etc. be sure to communicate to the client that their invoice can take up to a month after closing to be processed. By establishing this time-line you give your firm a chance to post any disbursements that may not be available right at closing, such as courier costs or title insurance.

By having real estate files billed a month after closing it allows your bookkeeper to catch any potential posting errors upon reconciling the month end.
