Hi there, @nbishop_springboardssolns.
Welcome to the Community family. I'm here to share a few details on how to handle your business and personal expense correctly.
Regarding the cell phone bill, you can create an expense for it. Then create a Bank Deposit as a refund/transfer from the personal account. The bank deposit must have the same expense account used from the phone bill. To create a bank deposit, you may read this article for your reference: How to Record Bank Deposits in QuickBooks Online.
For additional, bills/expenses will increase the expense account while the bank deposit will reduce the expense account.
For your future reference, you can read these articles to handle your business and personal expenses:
Also, I encourage seeking help from your accountant. This way, they can offer you some advice about personal and business funds.
Fill me in if you have further questions. I'll be around if you need help.
