Hello there, @BCS2020.
I've got some insights about the synchronization of new products between Shopify and QuickBooks Online (QBO). I'll also recommend configuring your integration settings to ensure your data syncs accordingly.
When you set up your integration between Shopify and QBO, you'll have the option to select how you want your new items to be created. You don't need to create all your new ones in Shopify if you've selected the Create New Items in QuickBooks Online or When a Product is created on Shopify, create new Items in QuickBooks Online option.
You can visit your integration settings in Shopify to check that the above-mentioned options are selected so your new products created in QBO will automatically sync to your Shopify account.
If you want the new items within your invoices from Shopify to be created in QBO, select the box before the Create New Items in QuickBooks Online setting.

If you want all your new products from Shopify to be created in QBO, select When a Product is created on Shopify, create new Items in QuickBooks Online workflow.
