Showback and chargeback are IT financial management practices used to attribute IT costs to cost centers or business units. The combined term showback/chargeback is sometimes used to refer to the family of practices that includes both reporting usage and optionally billing internal departments. Showback reports IT resource consumption and associated costs to business units without transferring funds. Chargeback, in contrast, allocates and bills internal departments for IT consumption, effectively transferring charges and recovering costs.

Implementation typically relies on metering of cloud services, on-prem systems, and software licenses. Common metrics include compute usage (CPU or vCPU hours), storage consumed, data transfer, network bandwidth, and application or user licenses. Data are collected, validated, and allocated according to a predefined model, such as proportional share, activity-based costing, or dedicated allocations. Transparency and governance are central to the model, with regular reconciliation to budgets.

Showback provides visibility and performance feedback without cash flow impact, allowing units to plan and optimize usage. Chargeback creates an internal billing mechanism that transfers costs to the responsible unit, which can drive cost containment but may also introduce friction and administrative overhead. The choice between showback and chargeback depends on governance, culture, and incentives; showback is generally easier to implement and less controversial, while chargeback can improve accountability but requires robust data and budgeting processes.

Benefits include cost transparency, better budgeting, and incentives to optimize resources. Challenges include data accuracy, scope creep, potential political pushback, and the need for clear governance to avoid disputes. In many organizations, especially those with cloud or hybrid environments, these practices are integrated with IT financial management tools and cloud cost management platforms.
