Definition
IT cost allocation is the process of distributing technology costs — cloud, SaaS, AI, shared platforms, telecoms, and labor — to the business units, products, or services that benefit from them, using agreed rules and metadata.
Why it matters
When IT spend stays centralised, no product owner optimizes consumption. Allocation makes spend visible on business P&Ls and enables showback, chargeback, and credible planning cycles.
