Hi @jennyc77,

I'll take care of this query for you. 

You stated that the costs of your products and services are in the POS system. Do the costs appear on the Product and Services tab as well? And you also mentioned that a report doesn't show these costs. I'd like to ask what kind of report you're referring to. 

A specific report I can suggest is Product/Service List. It lists all your products and services, along with their price, cost, and quantity on hand (inventory).

I'll place this article here for your future reference: Change product and service item types in QuickBooks Online. In case you'd like to edit the type of product or service you have on your QBO company. It also has steps on how you can adjust inventory items. 

Do you have any other concerns? Place them below, and I'll get back to you.
