Is there any way, when importing products to QBO, to include the class and/or category?

I'll gladly help and provide some information about importing products in QuickBooks, @Gryffin.

I can see that the option to import products with class and category in QuickBooks Online is a crucial feature for any business. Discovering new ways to adapt to our customers’ needs is how QuickBooks gets even better. 

Your feedback helps our Product Development team determine which feature will be implemented in the next future update. The change is also based on how popular a specific feature request is. 

That being said, I suggest submitting a product suggestion directly to our software engineers. We're taking notes of your ideas and insights. Let me show you:

1. Go to the Gear icon at the top. 
2. Click Feedback.
3. Enter your comments or product suggestions.
4. Then choose Next to submit feedback.

In the meantime, we can only add class field to each product manually. 

You can also check out this resource for further insights in importing a list of your products and services from Excel or Google Sheets to QuickBooks Online: Import products and services.

Additionally, let me share this article for future reference in modifying the item type for a product or service: Change product and service item types in QuickBooks Online.

Keep me posted if you have other questions about importing products with class and category. I'll be around to help always. Merry Christmas!

Completely agree – the migration experience from Desktop to Online has been horrific, and this is further adding to our headaches. Please add the ability to import Class information to the Products and Services.
