About the Clients tab
The Clients tab shows you a list of all of your clients, whether they're on Xero or not. Filter your clients by Xero subscription type or business structure, or group clients to suit the way you work. Quickly access the Xero organization of clients that are on Xero, and create new Xero organizations for clients that aren't. If you use Xero Practice Manager, you can import your existing clients into Xero HQ.
