Can I change the date of a bulk of invoices at once?

Yes, you can, @Telpeer. I'll share the steps below on how to change the date of multiple invoices at once using QuickBooks Online (QBO) Advanced.

You can use the batch transactions tool in QBO to edit up to 150 invoices at once. However, this is exclusive to QBO Advanced users only. If you're not subscribed to one, you'll want to consider upgrading your subscription.

To change the date of your invoices, please refer to the steps below.

1. Go to Sales and select Invoices.
2. Put a checkmark on the invoices you want to edit.
3. Click the Batch Actions dropdown, then Edit.
4. Make the changes and click Save.
