Register pre operating expenses

Prior to operating a business I incurred in setup fees, and inventory purchases that I paid with with personal funds, how do I register those transactions as Accounts Payables, and later repaid them as income begins to come in. I am sole proprietor. I would like to be able to repay myself as funds are available.

Similarly, if I buy an airline ticket, work related, but I pay with a personal credit card, how do I create an AP to that expense?

You can use Expense Claims to record expenses incurred prior to beginning your operations and business expenses paid from your personal credit card. See guides - Use expense claims | Manager
