Hi jacob-miles, 

Yes, it's possible to do this from the Sales settings by following the below steps: 

1. Navigate to the Settings icon in the top right of your QuickBooks file 

2. Choose Account and Settings 

3. Select Sales 

4. Under Sales Form Content select Preferred Delivery Method 

5. From here you can set the invoices to send later and Save 

This will set your future invoices to default to Send Later. 

Thanks, 

Rebecca
