Hello, liquor2005.

Thanks for joining this thread. I'm happy to point you in the right direction for your QuickBooks Desktop account.

In this instance I recommend reaching out to a member of the QuickBooks Desktop Support Team. Agents have specialized tools, like the ability to share your screen, to take a more in depth look as to why only a select few of your sales are showing after the sync, as well as the errors you mentioned. With multiple issues, being able to see what you see will allow them to work more efficiently and give you the best info. Here's how to get in touch with the team:

1. Go to Help, then select QuickBooks Desktop Help/Contact Us.
2. Select Contact Us.
3. Give a brief description of your issue, then select Continue.
4. Sign in to your Intuit account and select Continue and then Continue with my account.
5. We'll email you a single use code. Enter your code and select Continue. (If you have more than one account, select the account you want to use and then Continue.)
6. Select to chat with us or have us call you.
