As a shop owner who doesn't use RepairDesks Inventory System - I am left without a way to accurately track COGs of Repairs section within RepairDesk

When editing a model, say a iPhone 11 within this menu - you're given a Retail Cost vs. Sale Cost - most shops only use the Retail Cost, where the Sale Cost goes unused. So the idea would be to convert, or add another section here for "Cost of Repair" - this would allow you to add screen cost, labor etc and leverage that against the Retail Cost section - thus generating COGs on each repair item. Since the only real variable in this industry is screen cost - once the other COGs are set in each subcategory - you wouldn't need to edit much of anything outside the Screen repair prices.
