Record and reimburse owner payments on behalf of the company.

I have a video that may help with perspective on your question. It doesn't matter how it was paid, is the title, found on my Youtube channel

Best way is to record a credit card type account entry, using the name of the vendor you paid, to record a liability to yourself, and then, when you reimburse yourself, record the payment to that credit card type account. When you reconcile your accounts, remember that credit cards are usually personal, and they should be added to your Due to proprietor/partner/shareholder accounts to determine your total debit/credit balance to ensure you aren't in a debit position if you're incorporated, and required to pay yourself a salary to get rid of the debit balance. If you're self employed, it's not an issue.

"They all also happen to be different methods which is worrisome"

That's because the users here are from various Countries, and our accounting rules and regulations also Vary.

For example, in the US, a Sole Proprietorship never "owes" the owner. There is not owing to/from yourself, for this tax entity type in the US. Business purchases made by owner using personal cash, check, credit cards, or even chickens, is just part of Owner Equity In. The owner has the right to take funds Out, at any time. There is no Debt liability here.

"the company is a Pty Ltd rather than a sole prop."

That's fine, but we don't know your specific account requirements. You need to read Support articles that apply to you; I was answering why you see Various methods. They don't all apply to you.

"I need the correct/most practical method for a pty Company specifically. which is why I asked about the usage of a short term loan ( current liability) made out to the owner."

What I recommend is asking your own Accountant what applies to you; once you know what it is Called, if you do not know how to make that work in QB, we can help with that part.

One way is to set yourself up as a Supplier and use the Accounts Payable ledger to track the activity
