Question about Adobe Acrobat licenses for our business

So we have 4 employees, 3 desktops that are used a-lot, and 1 laptop that is used a little less frequently, we run a famly owned/operated funera home.

We use one main gmail account as our business account, and everyone just signs into that email and uses it.

I was just on the phone with an Adobe rep, to inquire about how many licenses we would need to make sure, if needed, all employees could use Adobe Acrobat at the same time on their computers. He instructed I would need 4 licenses, and that each license would need to be assigned to an email address.

The problem is…we only have that one main business email address, so OK fine no big deal, I would just ask them to use their personal emails to assign the licenses to them?

My issue with that though is, how would that work in terms of the business’s ecosystem? Would work that they do on each their licenses , be available for everyone to see on the Adobe dashboard in order to keep everything like saved files, forms, etc accessible for everyone, like a cloud, without having to send things to each other?

Also, the bigger issue, when sending a document electronically to be signed, wouldn’t those documents then show up in the customers inbox from the email associated with their license, meaning their personal email addresses? Instead of from our business email?

I feel like that will just create a lot of confusion and make things be all over the place and even more confusion on the customers end. Because like I mentioned, the way things work now, everyone just uses the main Gmail account, so anytime anyone sends an email it comes from our business account and everyone can see the same Google Drive and email inbox.

I was kind of hoping we could just create the Adobe account with our business email address and just buy four licenses so multiple people can use it at the same time, instead of signing up the other users, and everything would be under our business email and come from our business email in regards to sending things to customers.

can anyone help address my concerns?
