How do I remove unneeded product items form invoice lists?

Let me help you manage your Products and Services, Jay. 

I know that having the products or services we don't need showing when creating an invoice makes us confused and unable to find the one we need. There is one way to remove or hide them to make it convenient.

Here's how: 

1. Go to Products and Services.
2. Find the product you want to remove. 
3. On the right side dropdown, beside Edit.
4. Click Make Inactive. 

If you ever added the product on the line items on the invoice, you can click the Trashcan icon to delete them. 

Moreover, I'm sharing these articles to help you manage your products and services:
