This new feature allows you to add a margin which increases the cost price for specifik distributors. This is especially practical in cases where you need to even out and adjust prices due to distributor fees and similar circumstances.  

Add and change margins to specific distributors in Products > System distributors. The percentage you put in here will be added to the cost price of any item from this distributor. PNA checks will also adapt to this setting. 

This is a great tool to balance and control pricing further.
