I appreciate you for reaching out to the Community, Wvd1. Let me provide some information regarding this. 

As of the moment, offering legal collection of invoices is currently unavailable in QuickBooks Online (QBO). Since this involves some personal matter that only you and your lawyer should discuss, it's best to seek your lawyer's advice and consider your options thoroughly before taking any action.

Additionally, you can personalize and add some specific information to your invoices and other sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online. 

Let me know if there's anything that I can help you with, and I'll be here to assist you in any way I can. Stay safe.
