Hi,

Thanks for your question.

At the moment, EasyStore does not support attaching invoices as PDF files to order confirmation or other notification emails. Invoice emails can be sent, but they are typically HTML-based, not PDF attachments.

As a workaround, you can include a link to the invoice page in the email so customers can view or download it online. PDF attachment support would require custom development or a future feature update.

I will add it to our feature request list, so that our DEV team can take care of it.

-Regards.
