For me, I learned by obsvering my mother who owns a small retail shop and how she did accounting. I also took a course at my high school.

I've not really done much of online accounting research so I don't know where would be the best place to point you. However, some of the major accounting programs are rather simplistic to use and can, usually, step you through it.

The most important thing early on is to just keep a good record of who you owe, how much, and why. If you don't have any employees that are paid yet you really don't have much to worry about. Simple budgeting should get you through.

When you start selling things and start having employees is when it starts to get complicated. Other than that just keep a record of what you bought from who and how much it cost.

I AM NOT A CERTIFIED ACCOUNTANT AND MY ADVICE SHOULD NOT BE TAKEN AS THAT OF A PROFESSIONAL. I AM RELAYING INFORMATION BASED ON MY OWN EXPERIENCES.
