It's good to see you here in the Community, @Tyler H.
Currently, QuickBooks Point of Sale (QBPOS) doesn't have the option to print monthly statements for customers.
I understand that you want to have this option in your QBPOS. Since this option isn't available, I suggest sending feedback directly to our product engineers. They may look into this suggestion and consider adding this option in future updates.
To submit feedback, you can go to the Help menu and select Send Feedback. Then, enter your suggestion and click submit.
