From IT cost center to shared accountability
This is part 2 of a series on IT Financial Management (ITFM). The series explores IT cost transparency, showback and chargeback, modern budgeting and forecasting, managing value through benchmarks and KPIs, freeing up budget for innovation, and building a mature ITFM organization as a source of competitive advantage.
“We are held accountable for IT costs, but we have no visibility of who uses what or which choices are driving those costs. That makes it impossible to manage at executive level.”
Sound familiar? Then the link between cost and decision-making is missing. Part 1 addressed a basic question: where is IT spend going? The next question follows naturally: who owns the consumption behind that spend, and who is accountable for the cost?
As long as IT costs sit only in a profit and loss statement, the business is likely to see IT as overhead. Business leaders see a number, not the services behind it. IT can see the choices that drive demand, but responsibility for the resulting cost is unclear. When budgets need to be reduced, the discussion becomes “cut IT by ten percent”, rather than which services, risks or capabilities should change.
Showback and chargeback help break that deadlock. Used well, they make the relationship between IT consumption, cost and accountability visible. Used poorly, they create another round of discussions about allocation methods.
"A chargeback without a narrative is often worse than no chargeback at all. You create resistance without changing behavior."
The problem with charges that tell no story
Many organizations already have a basic form of chargeback in place. Costs are passed on, but without a clear link to consumption. The allocation method is simple, often based on headcount, because it is easy to administer.
For the business, this feels like a tax. An IT line appears in the budget, with a cost they cannot see or influence. Leaders do not recognize the services behind the charge, cannot see the connection with their own decisions and have little reason to engage in optimization.
As long as IT costs remain an opaque burden, it is difficult to have a meaningful conversation about investing in new digital services, rationalizing legacy systems or retiring capabilities that no longer deliver sufficient value.
Why transparency alone is not enough
In the first article, we set out the foundation: visibility of IT spend by service, application and business area. That is necessary, but it is not enough.
Transparency without ownership produces a report, not a management tool. Central IT budgets rise, finance raises concerns, but the connection between business choices and IT costs remains unclear. Business leaders can see that their IT charge is increasing, but not which levers they can influence.
Cost transparency shows where the money goes. Showback and chargeback clarify who is responsible for the consumption behind it.
Showback and chargeback: what is the difference?
Showback shows a department, business unit or product team which IT services it uses and what those services cost. Nothing changes financially. Budgets remain central, but consumption becomes visible to those who create the demand.
Chargeback takes this one step further. Costs are not only allocated; they are charged to the relevant owner. Adding a service or application then has a direct financial impact on that owner’s budget.
Start with showback. Showback changes the conversation without immediately introducing budget politics. It gives the business time to understand a different view of IT costs, allows the model to be tested and brings inconsistencies to the surface early. At Eraneos, we regularly see organizations wanting to move straight to chargeback. In practice, this often leads to debates about allocation before the business recognizes its own consumption. Charging costs without a clear explanation can be worse than not charging them at all. It creates resistance without changing behavior.
How showback changes the conversation
When business leaders can see the services they consume, the conversation becomes more specific. They can see how many digital workplaces, CRM licenses or data services they use, what those services cost and how consumption develops over time. That leads to different questions: Why are we using several applications for the same process? Why is this legacy system still running when an alternative already exists? Why do we have significantly more licenses than active users?
The first response is often defensive. After a few conversations, the focus tends to shift to a more constructive question: what are we going to do about it? That is the value of showback. It does not merely make costs visible but also gives the business and IT something concrete to discuss.
From showback to financial accountability
If we know who uses a service, who should own the financial consequences? That is when chargeback becomes relevant.
Once IT costs are charged to the budgets of business units or product lines, responsibility shifts. Retiring legacy systems or consolidating licenses creates visible budget headroom for the owner involved. Chargeback is a powerful instrument, which is why it should be introduced only when showback is trusted and the conversation about consumption and value is already established.
Mature organizations do not use chargeback as a penalty. They use it to bring decisions and consequences closer together. This creates room for more deliberate choices: where do we want to increase investment in digital services, and where can IT costs fall without reducing value for customers or citizens?
What it delivers
At Eraneos, we see the same pattern in organizations where showback and chargeback are working well. The conversation shifts from “IT is too expensive” to “Which services do we really need, and where can we simplify or rationalize?” Finance, IT and the business work from the same figures. In practice, the first opportunities often sit in overlapping applications, unused licenses and services that have grown over time without clear business ownership.
The main investment is in a reliable cost and consumption model, as well as the processes required to support showback. The benefits outweigh the effort when the budget released through optimization is used deliberately for innovation rather than simply absorbed into a wider budget gap.
Questions for your leadership team
Ask yourself three questions:
- Does every business unit or product line have a clear view of the IT services it uses and what those services cost?
- Is that information seen as useful input for decisions, or as an opaque charge that cannot be acted upon?
- How often do you discuss with the business where IT spend should decrease and where additional investment is justified?
If these questions are difficult to answer, then you, as a CIO or CFO, are likely to remain stuck in the same discussion: “IT is too expensive”, without clarity on the choices behind that cost.
Start small
Choose one value stream or business unit. Create a simple showback view and make it a regular topic in the quarterly management cycle. A focused pilot will reveal patterns quickly and often changes the conversation for good.
Showback and chargeback are not objectives in themselves. They are management mechanisms that create transparency, strengthen decision-making and influence behavior. They move the conversation between IT, finance and the business from IT as a generic cost line to an explicit discussion about cost, accountability and value.
Every month you wait is another month in which the business does not take ownership, and you, as CIO or CFO, are left defending IT spend rather than managing it.
