Good day, @kelgibson17.
The option to delete customer type is unavailable in QuickBooks Online (QBO). Although, you make them inactive so that they won't show up in the Customer Type drop-down list.
Here's how:
- Go to Sales and select Customers.
- Click Customer types on the upper right side of the window.
- Select the drop-down list beside Edit and choose Make inactive.
- When prompted, click Yes.
