Let me share how it works, Tlh121018.
The accountants won't be able to view each other's requests and documents. It is to keep the work safe and confidential. You'll want to share the documents with the other accountant so they can see it.
For more information, feel free to read this article: How to use the My Accountant page.
Get back to this thread if you have additional questions. We'll reply as soon as we can.
