The invoicing staff must handle recurring invoices. They must wait for shipment notifications from the shipping department, wait for the accumulation of billable hours from the payroll department, and wait for the accumulation of rebillable expenses from the accounts payable department, all of which can require several days to receive. This chapter addresses majority of those issues. In situations where a company knows the exact amount of a customer billing well before the date on which the invoice is to be sent, it is beneficial to create the invoice and deliver it to the customer one or two weeks in advance of the date when it is actually due. This way the invoice will likely be paid on time, which improves cash flow and reduces a company's investment in accounts receivable. Early billing removes recurring invoice creation from the closing process. A major delay in the closing process can come up in case expenses are being rebilled to customers. In such a situation, one may immediately issue invoices to customers for everything but rebillable expenses, thereby removing the rebillable expenses issue from the closing process.
