Good day, Microgreens SF.
I understand that you want to add a tip to the invoice.
While adding tips is only available to sales receipts, the best option I can is to create a new item in QuickBooks Online. Then, we can add it as a separate line to the invoice.
- Go to the Sales tab and select Products and Services.
- Click New, then select Service.

Once done, let's create a new invoice and email it to your customer. I've added some articles for more details:
I'll be here if you have more questions. Stay safe!
