Service Cost Vs Staff Commission
It would nice if we can have an option to add a cost to the services as we can do in the products. service cost could be lump sum number or it could be percentage of product type, ea. each hair wash need X Shampoo i usually sell, each package of shampoo is good for 10 hair washes. means the haiwash costs me 0.1 X Shampoo, means every 10 hairwashes should show -1 X Shampoo in inventory list.
That being said, the cost of each 10 hair washes should be subtracted from my employee commission as well.
