Hello there, rmgardening82,
What URL are you seeing? Are you referring to the online payment link? If so, follow these below to turn it off:
- Click the Gear icon.
- Select Custom form styles.
- Click Edit on the invoice template.
- Ensure the online payment is unticked.
If you're referring to something else, please leave a reply so we can assist you further.
Here's an article for sales form customisation: Customise invoices, estimates, and sales receipts in QuickBooks Online.
I'll be right here if need anything else.
