There is a setting that needs to allow for this. Also a permission. Show/don't show cost.

Or, we build as a black box for their company. With settings, could be global.

8/19/19: email from Tarmac Cultivation: "Can you help us get the COST field and EXTENDED COST field built into the [Bulk Edit Items] tab within the invoice page? We need to transfer our cost of goods onto the COST that we’re charging our dispensaries prior to distributing product. The current process is cumbersome and this will help lighten the load big time (as opposed to deep diving on each individual line item)

We have a production facility as well as a Retail facility that function within the same corporation. When we produce products, they are packed into a retail package and carry a Retail Sales Price. The sale price needs to be marked up in order for our Retail store to be able to scan and sell products, and the cost information needs to be available for us to see and pass on to our other stores. 

Let me know what the cost is – happy to smooth things to make it go faster..."
