RE: Printing Attachments along with invoice
I posted your question on Twitter, but so far the responses seem to indicate that it is not possible to include attachments as part of BC SaaS Invoice and PO printing.

You could potentially develop a custom extension in AL to do what you want, but I don't know how much effort / cost that would require.
However, there is a product that is specifically designed to do what you have described for other ERP systems. But I think it requires an on-prem server, it will require customizations to the BC reports you want to send, and I don't know if it is compatible with the BC SaaS report printing process. But it is probably worth looking into.
It is called Liaison Messenger EDD, by Liaison Software:

It is incredibly capable with lots of features for sending documents to customers and vendors with file attachments, and much more.
