You have two ways to import your invoices in bulk, Anna_Reznik.

The option to do this is only available in QuickBooks Online Advanced version. You can upgrade your version or try out the 30 days trial to do this task.

Another way is to visit our App Center and look for a third-party app that lets you import the invoices in bulk. QuickBooks Online connects to hundreds of different apps and I'm sure you'll find one there.

To access this within QBO:

1. Click Apps on the left panel.
2. Select Find Apps.
3. Click the Browse category drop-down and choose an option based on the task you need.
