Loan Payable / Reimbursement

@DavBkpg 

Are you a sole proprietorship?  If so, the $2,000 you put into the business is Owner's Capital (equity account), not a loan.  Money put into or taken out of the business is recorded to Owner's Capital.  The expense paid personally can be recorded as a $0 bill in QBO: go to New > Bill, one line 1, enter the expense as a positive amount, and on line 2, enter Owner's Capital as a negative amount.  Then, to reimburse yourself, record a payment (check or expense transaction) to yourself and assign Owner's Capital to the payment. 

If you're 100% owner of an S-Corp, use Shareholder Contributions (equity account) for the $2K and the negative amount on the bill.  Use Shareholder Distributions (equity account) for the reimbursement.
