Cloud cost
Showback vs. chargeback
Showback reports each team's cloud spend for visibility only. Chargeback bills that spend back to the team's budget.

Definition
Showback is the lighter and more common practice. Each team sees a report of what its tagged resources cost. No accounting entry goes with it. The goal is awareness and a change in behavior, not a budget transfer. Chargeback goes further. It moves the actual dollar amount into the consuming team's cost center. That creates real financial accountability. It also creates real friction if the tagging and allocation are not accurate.
Teams without a mature FinOps practice usually get most of the benefit from showback alone. They save chargeback for cost centers large enough to justify the accounting work.
Where it shows up
Showback and chargeback both draw on the same tagged cost data. Showback presents it as a report that a team can view for awareness. Chargeback moves the dollar figure into the consuming team's own cost center in the finance system. A real accounting entry goes with it.
What makes it expensive
Do not adopt chargeback before tagging and allocation are accurate enough to support it. You create real friction over a number nobody fully trusts. A team billed from a number it can dispute will dispute it, and the program rarely recovers. Coverage has to be high, and stay high, before the first internal invoice goes out.

A total nobody owns, nobody fixes.
An unattributed cost stays unowned. CostMon assigns spend to an owner, so someone can act on it.
