Wave is a solid option to send invoices and track where all your cash goes—including cash coming and going. It's a full-featured business app that makes it easy to send invoices, access detailed reports, and (if you need it) even reconcile your accounts for free. Wave's invoicing features are intuitive to navigate and include several templates, so you can customize the layout and design. To create an invoice, click Create a new on your dashboard, then select Invoice. Choose from several templates, add a logo, and adjust colors. Need to add a discount, adjust pricing, or add a note? You can do all that with the click of a button. And with Wave's mobile app, you can do it from anywhere.
