Customers ability to view their own invoices without being users?

Hi all,

Is there a way to send email with custom link to a customer to see their invoice directly on their browser (not pdf) whitout them having to register as website user?

We receive a lot of invoice from supplier on quickbook and other ERP and we don’t need to register to see them and pay them directly on their respective platform. We would like to do the same with ERPNext.

Thank you for your help!
