How can i enter my creditcard balance?

How can i enter my creditcard balance? I actively use my creditcard to make purchases for both my customers and my business. It seems though that i can not make the system "see debt" if that makes sense.

If i start with an opening balance of say $-1000 i OWE (repulsive horrible evil) JPM Chase one thousand dollars. When i make a payment to the card of lets say $250, the balance should then read $-750... Etc

Any idears?
