In 12 months you will be just like
@TooFineAPoint , explaining to someone else how or why they should incorporate.
It's not at all "too complicated", now that you know where to start.
Working in small business taxes when I was young I learned a few things outside of the ins and outs of accounting.
(1) Business Owners who understand their books and "accounting" make money. Those who are financially illiterate (no offense), are left to mediocrity financially speaking. Their work might be good, but they weren't from what I saw, as financially successful.
(2) Small business owners can build great businesses. Doctors eat your heart out. A guy with a plumbing company, some financial acumen, and who can manage a couple crews can make great money.
If you're in business for life, you should learn about business. It's in your interest. Accounting, Sales, Law, you have to be a jack of all trades. Everything you learn is an asset, knowledge is power.
Also , get a seperate bank card for your business. Buy all your business expenses and put all your sales into that same bank account. Everything is kept seperate and counted that way. The bank is the "control". Everything gets counted as it runs through the bank.
