Owner's Draw

Owner's Draw

Example:  I have a charge account at ABC Company.

During the month I charge one $50 item for my business. I also pick up a $20 item for personal use.  

At the end of the month, I receive a statement with a balance due of $70 and I want to PAY THE ENTIRE BALANCE WITH MY BUSINESS ACCOUNT. 

Since the $20 personal purchase can't be assigned to Owner's Draw when creating a new bill, how do I handle this?
