Can I set up a category for separating personel charges on company credit card?

Hi there, 

Welcome to the Community. I'll be happy to guide you in the right direction so you can set up your categories with ease in order to keep track of your transactions. 

Based on the details you've shared above, I see you achieving the result you need by utilizing the Classes feature offered in the program. Classes represent meaningful segments in your company, like store departments or product lines etc. I encourage you to learn more using this article here: Create and manage classes in QuickBooks Online.
