I need advice on how to record a specific type of transaction:

Our company has an outstanding liability to a freight company for services previously rendered. Typically, we would enter the "bill" and use the "bill pay" function to write a check to the vendor on the due date of the invoice. Instead of our company writing a check to 
"said" vendor, one of our employees used their personal credit card to pay the invoice; and, I'm insure of how to post this.

Regarding a reimbursement, we typically write a check directly to the employee. It's usually for something like "lunch" or "stamps"; however, this is a very large dollar amount ($20,000). I want to be able to see the original vendor invoice, but I also need to reimbursement my employee.

Help!
