Hello there, jackmurphy. 

We can go to the Customer's profile within QuickBooks to check if the names is both entered in the Company and Display name as field. 

Let me show you how:

1. Go to the Sales menu and click Customers.
2. Select the customer's name and click Edit at the upper-right.
3. Enter the Company name in the customer's name in the Display name as field.
4. Click Save.

Let's go back to your shopVOX account and sync an invoice to verify if it now displays other customer details. 

I'll be here if you need more help!
