It is so easy to create bills and automatically send them, duplicate past bills, and set automatic reminders. There are other offerings I don't currently take advantage of, but for what I use it for it's brilliant. I moved to Wave from Paypal because Paypal raised their prices without my being aware of it. Wave has reasonable pricing while focussing on a great billing system. I also love how they simplify legal language on the side of the original text when they have a change of terms. I now use Wave for all of my billing. Customer support has also been very friendly and helpful.

Very easy and practical to use, you dont have to have an accounting background to be able to use Wave. I found it really useful using it to invoice my clients and track payments, etc.

Very easy to umport bank statements and CSV,s for reconcilliation. Has decent dashboard showing cash flows and profit lossees in the last 12-24 months. I enjoy the expense breakdown section
