Welcome aboard, @pjenkins2019-yah.
Let me get into your customers' menu to help you remove them in QuickBooks Online (QBO).
In QuickBooks, there’s no option to permanently delete a customer. Otherwise, we can make their profile inactive in your lists. This way, those customers will be removed from all your reports and so forth. I’ll show you how:
- From the left navigation pane, select the Customers & Leads menu.
- Select the Customers tab.
- Look for the customers you want to be removed or inactive from your lists.
- Click the dropdown icon under the Action column. Then, select Make inactive.
- Click Yes to confirm the removal.
Also, if you want to make changes to your customers, I recommend checking out this article: Edit customer information
