Our employee bought parts with a company credit card.

I need to add a journal entry manually for it which should be this I believe:

Credit the Credit Card. 

Debit the expense account.

Where it gets tricky is that I need this tied to the invoice and PO because that's how I tie it to the specific job. And then I need to mark the invoice as paid. What's the best process to do that in Sage Contractor 100?
