Calculate Overhead (job-related costs only)
Select the Calculate Overhead field if you want Project and Job Costing to calculate overhead amounts for this cost and pass the amount back to Purchase Orders. (Purchase Orders creates the G/L entries for the additional costs.)
Overhead is usually calculated on the discounted extended amount.
For example, you would not select this option if an invoice had additional shipping costs for which you didn't want to calculate overhead or labor.
The program also lets you specify whether overhead or labor is calculated if you expense the additional cost.
