Hello there, Antoinette2.
The Send Queue feature is unavailable in QuickBooks Online. Once you create invoices and choose to send it later, you can see the "Not sent" status on the Invoices page.
Once you're ready to send the invoices, you can send them by batch. Here's how:
- Click Sales, then go to the Invoices tab.
- Choose the invoices you will send.
- Click Batch actions, then choose Send invoices.
I've attached a screenshot to guide you.
Once done sending the invoices, you can see "Sent" in the invoice status. I've attached another screenshot as your reference.
Don't hesitate to get back to us if you have more questions. Have a good day!
