Quickbooks is the #1 Small Business Financial Software.
Since I’ve been practicing as a CPA for almost 40 years now, I can tell you with a lot of experience that you get an enormous amount of capability combined with amazing ease of use. I also spent some time working with the mother-of-all-complexity software (SAP) and can find amazing similarities between the two. (Price is not similar btw.) The online version is now the better product. The desktop version no longer has a permanent license to use – if you buy it now, it will terminate in a year or two.
I’m a certified ProAdvisor, which means I can help you with your specific issues.
Don’t forget, once you form a corporation or LLC, you still have to keep it legal by having annual meetings, board minutes, etc. Forming a corporation or LLC is not a “get out of liability free” card unless it’s properly maintained.
