Inventory payments

Hi, Would be very grateful to learn the breakdown of the transactions to make the following scenario make sense: Owner setup Inventory on QB Enterprise (desktop) after he already paid for some of the bills through his personal account. He has been reimbursed for these payments. The inventory was entered without a bill. Now that the bills have come in, how do I enter in and ensure the inventory and bills agree, at the same time recording his reimbursement, and not affecting reconciliation? Actual Accounts associated with this and debit/credit transactions will help immensely to record all this accurately. I feel that the reimbursement has to be recorded initially - but then how do I adjust the inventory and the bill? Would his reimbursement go to a Owner, Other Current Liability Account, and then record from here to the inventory/bill? It's a puzzler to me. Thanks so much! Nancy
