I was using Quickbooks mostly to invoice my clients and it was far more than I needed. Moon invoice meets most of my needs and it only cost $10. When I have had minor issues, support (despite being overseas) was extremely helpful and very responsive (they always respond the same or next day). I’m quite impressed. I would’ve made some different choices about terminology or flow, but those issues are minor. This is a very useful little app. Updated two years later. The support people are all in India which makes getting support very difficult. It’s only by email. I had a problem with a bug (where I couldn’t assign a task properly to the right category) and they suggested I upgrade to their new Pro version for free. Unfortunately it seems impossible to transfer my data to the new version. Not helpful. Sometimes you get what you pay for.
