The worst thing you can do as a freelancer is to forget to invoice your clients. It happens to the best of us. Wave Accounting allows you to easily and accurately manage all of your invoicing and payments. It also connects to your checking or savings account and your PayPal. You can also access this on all of your devices. The best part is that once the invoice is entered it will send automatic updates to you and your clients when the invoice is overdue.
