Hello adkjim1,
Currently, we cannot sync your email contacts with QuickBooks Self-Employed. You still need to enter them manually.
- In the Invoice window, click the Add customer hyperlink.
- Select + Add new and enter the necessary information.
- Click Save.
You can click the Feedback option in the upper-right corner to let our developers know about this.
We'll be right here if you need anything else. Have a great day!
