Hello, I love Mint.com for small businesses that do not send invoices. I am hearing many say they have a hard time attaching all their checking accounts. Business and Personal accounts from the same bank can be hard to attach and PayPal well they do not seam to like each other.
So, I am taking a look at www.WaveAccounting.com and http://outright.com for your Free accounting needs. I will get back to you on what I like or dislike.
I am also looking into http://www.shoeboxed.com for keeping your receipt safe and organized.
