Hi JeanG!
Thanks for the reply. Allow me to share some info and help you with the invoices.
Ideally, the sales information will be transferred to QuickBooks Desktop when you do the Financial Exchange. In QuickBooks Point of Sale, you'll want to make sure that the customer is set up correctly. From the customer's profile, add all the necessary details including the shipping info.
Please check this link: Financial Exchange Overview. This will explain further how to share your data from QuickBooks Point of Sale to QuickBooks Desktop and vice versa.
With regards to the callback request, please consider the support hours. QuickBooks Desktop Point of Sale Support Team is available Mondays to Fridays from 6 AM to 6 PM PT. You'll want to send another request within those hours.
Here's the link on how to get help from our Point of Sale Support Team: Contact Payments or Point of Sale Support.
Post again here and I'll assist you. Take care!
