Hello @office177,
We have separate support who can better address your concern about customizing the port and server setting when sending your invoices.
That being said, I'd recommend contacting our Developer Support so someone can help you review and set up the appropriate setting.
To do so:
- Go to the Developer Support page.
- Tap QuickBooks Desktop.
- Hit Ask a QUestion.
Lastly, I've got you this helpful article for updates from our developers: Developer Support Blog.
If there's anything else that I can help you with, let me know in the comments. I'll be here to lend a hand.
