I use it every day. Switched from Quickbooks Online at the beginning of this year after they jacked their prices up. I'm pretty impressed with the features for it being a free product. The invoices it produces are very professional looking, and I like the fact that I can email the invoice to the customer from within Wave, and they can pay it online with their credit card or e-check. The phone app works well too and makes it easy to create and send an invoice when I'm in the field. There are a few quirks to it, and it's not the fastest thing out there, but overall I like it.
