Define how costs accrue

With Microsoft Project 2010 you can control when costs accrue in tasks and their assignments. This setting can override the automatic generation of the costs associated with resource usage (which are by default prorated) and place cost realization at the beginning or end of the task. This might be used for alignment when the costs are realized by billing systems and it can help you manage cash flow in your project. You can define the cost accrual methods for resource costs and the fixed costs for tasks.

What do you want to do?

Change how resource costs are accrued

Change the fixed-cost accrual method for new tasks

Change the fixed-cost accrual method for existing tasks

Change how resource costs are accrued

1. On the View tab, in the Resource Views group, click Resource Sheet.

2. In the Resource Name field, click a resource.

3. Right-click to select Information, and on the Resource Information dialog, click the Costs tab.

4. In the Cost accrual list, select the accrual method you want.

   Caution:  We recommend that the resource cost accrual setting be made when a resource is created, and then not modified. Changes may move planned and actual costs, which could change actual costs

Note: Per-use resource costs are incurred at the start or finish of an assignment, not via the prorated accrual method.

Tip:  A safe way to change an incorrectly set accrual value is to create and assign a new resource and transfer remaining costs from the old to the new resource.
