Purchase Order Acknowledgements in Cloud

Summary

Are most companies using these today?

I hope this type of question is allowed.

We are in the middle of an implementation and have a PO acknowledgement API in our current system. It generates an email that has a button in which the vendor can reject/approve the PO from the email. In Cloud I understand that PO emails contain a link for which the vendors need to sign into the supplier portal in order to acknowledge the PO.

We use a lot of small vendors who we have difficulty getting to use the current button, and I'm sure that number will grow if they are required to sign in to acknowledge.
