When i email an invoice to my customers it has "Review and Pay" links in it. This confuses my customer. can i remove them?

Greetings, dneedham100.

 I’d be glad to help walk you through removing the "Review and Pay" links on an invoice you’ll send to your customers.

Here's how:

1. Go to the Gear icon and select Account and Settings.
2. Choose the Sales tab, then go to the Online delivery section.
3. Under Additional email options for invoices drop-down, select Plain text.
4. Click Save. 
5. Then Done.

I've added screenshots that serves as your visual guide:

Now, try sending an invoice to your customer, the "Review and Pay" link should not appear anymore on the invoice.

If you need help in customising your invoice, here's a link for the detailed steps for reference: Customise your invoices, estimates, and sales receipts in QuickBooks Online.

That's it! If you have any other additional questions about invoices or other QuickBooks related concerns, you can post them anytime here. I'll be around to help.
