I use NolaPro for my small business. I use their hosted service. It has been 100% error-free since the day I purchased it. I had one problem that turned out to be something I messed up in my browser. They were friendly and helped me resolve my problems. I'm also using Linux as my desktop, so the Windows standalone products, like QuickBooks, were not an option.
The reports are great. The product is easy to use for accounting newbies like me, but contains all of the features needed to run a small business. I love the fact that I can enter my expenses from any browser in the field. And, the price is right!
If you're thinking about starting a new business, you should consider NolaPro.
I use Anthill OS (because my company's cheap). It's easy to setup and use. It gives decent error output, although that could be improved. It's been an incredibly useful tool for our developers. Kudos to the Anthill team!
