From my understanding, Regular price is what I am selling an item for (That is not on sale) and purchase price is what I paid for to get the product.
Example - I paid $54 for 25 lanyards. I am selling them at $4.00 each. In atum, it shows a negative gross profit. Why is this and how do I fix it so I can keep record of what I paid for to get said product and what I am selling it for?
