I've basically put in $300 of my own money to Incorporate, purchase initial equipment, etc. Now I have my EIN and a Bank account and bookkeeping software - how do I ensure my owner's equity is appropriately reflected and I'm not actually in the hole?
The way my accountant had me handle this was to create a liability account in QuickBooks called "Loan from Kyle". I had a few times where I had to deposit money into my business checking account, and I categorized the deposit as this account. Then, on the balance sheet, it's properly displayed as a liability, and it's recorded that the money came from me.
When I eventually wanted to repay myself, I just wrote myself a check and categorized it as "Loan from Kyle", and that liability went away.
