Hi adrianitarofe,
When you make a customer inactive or delete it in QuickBooks Online, the customer is removed from the Client/Customer tab, reporting options, and any other place where customers are listed. To make a customer inactive please see the steps below:
- Go to Sales, then select Customers or Client tab.
- Find the customer or client, then in the Action column select Make inactive.
- Select Yes to confirm the request.
