I want to make sure you'll get the right amount of information about uploading a bulk file in QuickBooks.
Those steps you've mentioned are only applicable if you have access or already have set up QuickBooks Commerce from within your QuickBooks Online account (QBO). With that, you may not have yet started with QuickBooks Commerce.
Hope you’re doing great. I wanted to see how everything is going about importing products in QBO. Was it resolved? Do you need any additional help or clarification? If you do, just let me know. I’d be happy to help you at anytime.
Looking forward to your reply. Have a pleasant day ahead!
