Keeping track of expenditure

By tracking expenditure, you can find individual system costs and tag them to the system or business owner. Transparent expenditure data helps to identify ROI and reward owners, those able to optimize resources and reduce cost. It can help you to determine what it is costing every month for a department or project.

Saving cost is a shared responsibility and you need to have a mechanism to hold everyone accountable for cost-saving. Often, organizations introduce a show-back or charge-back mechanism to share cost responsibility between organizational units.

In the show-back approach, the centralized billing account informs each organization unit regarding their expenditure but doesn't charge the actual amount. In the charge-back mechanism, each business unit within an organization manages its own budget under a master payee account. The master account charges back the amount to the business units as per their IT resource consumption on a monthly basis.
