It is a free site, and perfect for small businesses, 2-10 people office with a small volume of invoices. allows to create professional invoices and keep track of who has paid and who I still need to collect from. Keeps all business related income and expenses in one easy to use place. A cool feature is the memorized invoices / recurring invoices that lets me just rerun the invoices next month.

Wave is free! It allows me to create professional invoices for my business and keep track of who has paid and who I still need to collect from. Wave makes tax time much easier for me because I can find all my business related income and expenses in one easy to use place. They also feature recurring invoices which is very beneficial to me as I no longer have to keep track of remembering and sending them myself.

Wave is really easy to use and set up. The learning curve to familiarize myself with the software was really short; I was comfortable with it after a few hours. The companion apps - Wave Receipts and Wave Invoices - are really useful. I have a partner (non-business), and all she has to do is take a picture of any receipts with the app... and I can do the rest. Also, it's FREE. You just pay for payment processing and payroll. Have the ability to invoice and take payments within one application is very useful.
