Owner transferred funds to personal account to pay subcontractors and expenses

This situation is a total mess. I have no idea how to record the transactions and reconcile the expenses. The owner of the corporation has transferred lump amounts from his corporate bank account to his personal account. He would then pay some of his subcontractors and make credit card payments to cover expenses that had been paid with his credit card.
Should I consider every transfer to his personal account as an owner withdrawal and then record the subcontractors and expenses as journal entries paid by the owner? How does that work when trying to claim expenses? Any advice would be appreciated.
Thanks
