Just adding this here for anyone else looking for clarification on importing batch invoices into QBO. The issue is you can’t with Sales Tax. I’ve gotten the error a few times that says QBO doesn’t support importing sales tax data at this time. I’ve confirmed with an agent. If you’re a business that uses QBO and you pay sales tax on your invoices from vendors /  suppliers , you have to manually add them for now or, use QuickBooks desktop. I’m not sure there are any third party apps that can do this and bypass that sales tax issue while a companies sales tax is turned on. Hope this helps folks in the future.
