First, you need to get some guidance from the parent company if they go through inter-company elimination process to prepare consolidated balance sheet report.
In QBO create Intercompany Accounts Payable Account (not main Accounts Payable A/P) >
you can select “Credit Card” Type > it will show as Credit Card group on the Balance Sheet. When you Pay Bills (or enter expenses), you can select this account instead of bank account > easy one step process only > however, if parent company has a problem using Credit Card type account then, you may need to set it up as “Other Current Liabilities” type account.
In that case, it becomes two step process > pay bills (or enter expenses) using Credit Card type as I/C clearing account > transfer the balance from Intercompany Accounts Payable (other current liabilities type) to Intercompany Clearing account (credit card type > new name). To transfer in QBO, you can use Transfer (create + sign > other > transfer) or write a Journal Entry (and make it reversible JE if needed).
Again, it’s a good idea to consult with your parent company who handles Intercompany accounts. And, always reconcile accounts on a regular basis.
On the parent company’s books, they should record this as an intercompany accounts receivable.
In QBO for Intercompany Accounts Receivable > select “Other Current Assets” Type (not main Accounts Receivable A/R type. In QBO, you can have just one A/R).
