Cannot QBO show the average cost of purchase items in the face of product and service page automatically?

Hello there, Buck Tsai.

I can see how important and relevant to generate the average cost of purchase items within the Product and Services page in QuickBooks Online. However, this option is currently unavailable.

You may want to consider looking for a third party application that can integrate with QBO and you help you get the average cost of purchase items. Then, click the Get app now button at the upper-right corner for the chosen app you may want to use to get this thing done.

Also, you may want to visit our blog website and sign up for our Newsletter. This way, you’ll receive email updates about our latest news and product improvements. 

Know that you can always tap me on my shoulder if you other concerns with QuickBooks. Take care and stay safe!
