Hi heytys,

Thanks for posting in the Community! I understand that you would like to import an invoice template in QuickBooks Online, however, this option is no longer available for newly created companies. Any company that has not already allowed the feature from QuickBooks Labs after 24/6/2021 will no longer be able to enable it. Any existing QBO companies with the feature are not currently affected and will continue to have access. 

However, we still have some great templates you can make use of when customising your invoice. Alternatively, there are 3rd party apps you can look into to create their invoices, but the majority of what is available in import styles is available within our template sets.

For your reference, you can check this article: Customise invoices, quotes, and sales receipts in QuickBooks Online. 

Message us back if you have any other questions, we're here to help.
