A big part of managing cash flow more effectively involves getting paid consistently and on time. One smart strategy to help ensure this happens is to invoice customers electronically. Electronic billing enables you to customize business invoices and set up automatic payment reminder emails as well as past-due notices. Once you set up a customer’s electronic invoice, it can go out when you decide without having to create a new one each time. Another tip: Consider offering small discounts to customers who pay their bills quickly.
