how do I delete items in Product/Services?

In QuickBooks Online, you cannot delete a product or service, Ray. Instead, you can make them inactive so that they no longer appear in your lists, reports, or transactions. Here are the steps to make a product or service inactive:

1. Navigate to the Sales tab.
2. Select the Products & services section.
3. Locate the item you want to make inactive.
4. Click the dropdown arrow next to the Edit button and select Make inactive.
5. A prompt will appear; click Make inactive to confirm.

Once an item is made inactive, it will no longer be available for use in new transactions or reports.
