I've been using Studiometry for a couple months now and it's been excellent for my needs. Makes tracking work and invoicing a LOT easier than it was with my old accounting software. It lets me track everything that I need to track for my development business (invoices, expenses, vendors, etc) for taxes and such, but simplifies out a lot of the accounting details that just burned time.

The company itself is great as well. I recently needed a way to export data from the program in a certain way to prepare a tax report that I couldn't seem to do easily with the existing features. A few days later they replied to my ticket and told me they built the feature for me and it'll ship early the next week. I'm extremely satisfied by the support I've gotten from them (much, MUCH better than my last accounting package, where you get a support rep from India just trying to get you off the phone).

I'd STRONGLY recommend this product!
