Expense reimbursement paid for by members

We are a small nonprofit and sometimes members will pay for approved expenses, then give us the receipts for reimbursement. We use QBO and I was wondering what might be a better way of recording these reimbursements.

As of now, I record a check to "pay later," with each item on the receipt separated to its appropriate account. Then when the check is written, the date is changed and the check number added.

We would like to use a Reimbursement liability account for ease of grouping those checks that need to be written, and also if we could reduce the number of "vendors" in quickbooks, that would also be helpful.

Thanks in advance.
