SlickPie allows you to invoice and bill online. Slickpie has been my favorite online tool for invoicing and billing for the past 12 months. Its interface is intuitive, it is simple and easy to use.
It has many features that I use in my business. I can create invoices using a variety of templates and it even allows me to add my logo. Management of clients through keeping all information in one place. Tracking expenses for my company.
