User Reviews

The service itself, for me, is one of the best out there as far as fees if you're an smb. However, the mobile app, while it looks nice is missing a lot of basic features like filter views for invoices. Hopefully this gets improved.

They really have the worst customer service. I used them for 6 months but had to get ride off them because they can't take care of them most basic requests. App isn't the greatest either.

Reader never ever works. I'm on my fourth one. Wish me luck, I'm gonna need it. Will be cancelling and taking my business else where.
