Hi tracyandsonspm!
I understand that you want to add a tip option to invoices. I'm here to assist you.
Currently, aside from the sales receipts, you can accept tips using the GoPayment mobile application. Just make sure you're using an updated app and card reader. Please check these articles for more details:
With regard to the invoices, I suggest you send feedback about this to our developers. Let them know that you need such an option. Go to the Gear icon and select Feedback.
I added this link if you need help in running reports: Run reports in QuickBooks Online. This includes articles on how to customize and save reports.
Post again here if you need more help in receiving payments. Take care!
