What does the company do well? Very simple piece of software for sole traders and small businesses. The product is low cost, simple to use. Power users amongst us may wish for a slightly wider raft of features, but you're not going to find that at this cost point. Mobile app is also pretty nice, I tend to use that more than anything else.
What does the company not do well? To be honest, when in the guise of one of the above, there is little to complain about
What about the company do you wish you had known before purchasing? I wish I'd known that it HATES working with Chrome on a desktop. The browser has a bit of a memory leak issue that causes the app to run really laggily if you have a lot of transactions to mow through. Swap to Safari or Internet Explorer if Chrome is your default for this.
