I appreciate you for coming back to the thread and providing extra details about your concern, Dropseed. I'll ensure that you can permanently delete the pre-filled text in the Tell your customers how you want to get paid box and return this to being blank each time you create a new invoice within QuickBooks Online.

The text information displayed in the mentioned box above is dependent on what is entered in the Invoice payments section. That being said, I recommend removing the content and leaving it blank from there.

Here's how:

1. Click the Gear icon at the top.
2. Choose Account and settings.
3. Go to the Sales tab.
4. Select the Invoice payments section. Then, click the pencil icon and manually remove the text or details on the box.
5. Click Save and Done.

I've attached a screenshot below for visual reference.

In case you need steps on how you can record full or partial payment for an invoice, you can read this article: Record invoice payments in QuickBooks Online.

Let me know if you need further assistance with this pre-filled text in the invoice in QBO. I'm always around to provide answers and clarifications to your questions, Dropseed. Have a great day ahead and take care.
