Hi there, @garth-ontrendmar.
I can provide information about the error you're getting when sending invoices to your clients in QuickBooks Online (QBO).
We received reports regarding users getting the same error message (Deliver Errors) when sending invoices. A ticket has been created and forwarded to Product Engineers. They're now working to fix this as quickly as possible.
That said, I highly suggest contacting our Support team so they can add your details to our notification list. This also helps our Engineers determine the number of affected users. An email notification will be sent to you once this has been resolved. I'll also inform you here when we get the update as well.
Here's how to reach them:
- In QBO, click the Help (question mark) icon at the top left.
- Select a suggested option, or type Deliver Errors.
- select Contact us and choose a way to connect with us.
To learn more about the support hours, refer to this article: How and when can I contact Support?
In the meantime, you can check out this article that contains troubleshooting steps about the error you're getting: Delivery Errors when trying to email a sales form.
I also recommend visiting our website for more tips and other resources you can use in the future: Self-help articles.
Let me know if you have follow-up questions about sending invoices or anything else QuickBooks. I'll be right here ready to help. Take care always.
