I appreciated adding more information about the issue, dlscornett.
Based on the details, we’ll have to configure the Email options for all sales forms settings to attach the invoice. Let me help you perform this task in your company.
For additional resources, this guide provides information on how to print invoices or get a link to share with customers. It also contains links to other processes you can do when using the Invoice feature: Create invoices in QuickBooks Online.
Don’t hesitate to let me know if you still need help with QuickBooks. I’ll be glad to assist further. Have a great day ahead.
