Hi jking,
It's possible that you set up the customer's delivery method to email.
Here's how you can check the setup:
- Click Customers from the left menu.
- Select the customer name and click on Edit at the top right corner.
- Click the Payment and billing tab. Set the Preferred delivery method to None.
- Click Save.
I've included a screenshot below for reference.
This should de-select the Send later or email option on your invoices by default.
I hope this gets you what you needed today. Don’t hesitate to post again with any questions. Have a great day!
