Resources are generally costed in two flavors - "variable expenses" and
"fixed expenses"
Variable Expenses
Some people charge
by the hour, some by the day, some by the year.
Fixed Expenses
Sometimes resource
costs are "fixed" such as the cost of a particular part or component
you need to purchase.
JCVGantt Pro allows
you to adjust how resources are calculated...and automatically figures
out how much these resources will cost you while you plan.
