How do i sign out of one client to enable me to sign into another client?

I can walk you through how to switch clients in QuickBooks Online (QBO) Accountant, @tasabaro22.

Here's how:

1. From the toolbar, select the drop-down menu with your client's name.
2. Select Back to practice.

It allows you to get back to your QBO Accountant page. Use the same toolbar to open a different client that you want to view. These are the steps to switch clients. Take a look at this article for more information: Open and review clients' QuickBooks Online or Self-Employed accounts. 

To stay on top of what you need to review for each client, I suggest you open this article: Do books reviews to finish your clients' open tasks.
