Can you disclose the process you followed here. Quickbooks Online Version 

My situation is similar. I do a monthly reimbursement for purchases made via an outside credit card not in our quickbooks system. In which I create a bill each month in bills for the employee submitting the reimbursement. Each transaction is catagorized by expense type. Then when I process payroll through a third party I reimburse the employee. I do a journal entry for payroll which includes the accounts payable transaction for the reimbursement. 

My question and or struggle is I need to see the expense under the original vendor so that I can track the fluctuation in spending at gl level and vendor level monthly. How do I then get the expense under the actual vendor it was purchased from not just listed under the employee reimbursement.
