How to link/update product cost price to/from employee contract
right now I'm wondering if there ist a possibility to link an employee contract with the monthly salary to the cost price of a (Service)Product.
For instance, I would like to have a Service Product "Senior Project Manager" which linked to 4 employees. Then, when I'm checking the project budgets based on a project timesheet, I would like to see that every employee is calculated on ther own, individual salary.
I know, an individual Product for each employee would fit my needs, but I'm a bit concerned about the effort that we have to put in updating/changing 35 "employee products".
Thanks in advance!
