Hi there, theguyuphigh1979.


The option to delete a contact on your customer's list isn't available. However, we can deactivate them so we can hide them on the list.


Let me guide you with these steps:


  1. From the Sales tab, select Customers.
  2. Select your customer's name.
  3. Click the Edit button.
  4. Click the Make inactive button.
  5. Select Yes.

Let me know if you have questions when processing payments online. I'll be around to help.
