I hope you're doing pretty well, Sharon-AKB.

I'm here to show you how to add your clients under your payroll subscription. We'll have to ad first the client's EIN to your subscription. These are the steps to follow:

1. Go to Employees > Payroll > Use My Existing Payroll Service.
   • Check the Use my existing payroll service option is not available if you can't see this option.
2. Under Identify Subscription, choose Use Subscription Number xxxxxxx (Payroll Subscription Version). You can select Other: I have an existing subscription and a Zip Code. Then, enter your information.
3. Click Open, then select Next.
4. Select Next to add the company EIN. Select Print or Return to QuickBooks Desktop. 

Once done, let's verify the Service Key. Go to the Employees > My Payroll Service > Manage Service Keys. Make sure that you can see the Active status when clicking View.
