Is there a way to send batch invoices of the same amount to multiple customers without having to buy Advanced since we don't need all of its features.

With QuickBooks Online Advanced, you have the ability to effortlessly create and send multiple invoices to multiple customers simultaneously.

Here are the steps:

1. Head to the Sales menu and select the Invoices tab.

You can use an importer tool as a workaround.
