How do I add a cost to each service I provide? I tried following the add service/products purchasing info. he purchase this product/service from a vendor Did not show up

I can walk you through how to add cost to each service in QuickBooks Online, @jmckinley. 

The option to add cost in service is available in QuickBooks Online Plus and Advanced. If you're using the Simple or Essentials versions, this feature will not show on the Product/Service Information page. 

If you're using the above-mentioned versions, let's unselect the box next to I sell this product/service to my customers. Doing this will help you add the cost for the item you'll create. 

To do this, here's how:

1. Go to the Sales menu and select the Products and services tab.
2. Choose the New button and click Service.
3. Remove the checkmark next to the I sell this product/service to my customers option.
4. The I purchase this product/service from a vendor checkbox will show.
5. Enter the amount in the Cost field.
6. Lastly, click Save and Close.
   
   

For more insights on how you can set up and track product and service items you buy and sell, feel free to review this article: Add product and service items to QuickBooks Online.

You'll want to edit the item type for your product or service. You can open this link for your reference: Change product and Service item types.

That should do it! Keep me updated if you have further questions about managing your inventory or service items in QuickBooks. I'll be happy to help you again. Stay safe and have a great day!

I have QuickBooks Essentials and that doesn't come up when I select one of the services I created. I tried creating a new one and it still doesn't show up.
