Hello there, tom274.
To view your client list and select a specific client to work on, here’s how:
1. Sign in to QuickBooks Online Accountant.
2. On the left-hand sidebar under YOUR PRACTICE, click Clients.

3. Use the magnifying glass icon (located next to the Lead accountant filter) to find a client.

4. You can also click the GO TO QUICKBOOKS dropdown above the Company Name, and you may see all your clients who have QB accounts.

This lets you quickly access a specific client or view a summary of all your clients at a glance.
Feel free to reply below if you have further questions.
