Hi there, @darnelia.
I'll direct you to the right support in integrating Shopify and Amazon orders into the program.
To learn more about the best way to sync these two apps with QB Online, I'd suggest reaching out to the apps' support team. Here's how to get their most up-to-date contact information:
- Go to Apps from the left menu.
- Search Shopify/Amazon in the search field.
- Locate the contact details under App information.
You can also go to our QuickBooks App Center to help you get the information you need. Please see this article for your reference: Find Apps.
That's it. I'll be around to help if you have any other concerns. Take care always.
