When you purchase a professional tax software, you get tax software, not bookkeeping software.  The software will create an invoice but after that you are left to track payments manually or using a bookkeeping software.

Lacerte does have invoice capability where you can track invoices and bill without the need of a bookeeper. I am a bit surprised that proconnect does not have since the input screen is a carbon copy of Lacerte

Hi, ProConnect does not track invoices within the software.  However, it does link to Quickbooks Online Accountant for creating invoices.  Please review this article: How to Create Invoices from ProConnect .  If you need further assistance, please reach out to our chat or phone support: How to Contact ProConnect Support.
