Business & Deployment
Total Cost of Ownership
The license is the smallest item: on top come integration, data preparation, operations, monitoring, training, review effort for errors — and switching costs if the vendor changes prices or models. TCO thinking protects against the cheapest demo and the most expensive surprise. Rule of thumb: rollout costs a multiple of the tool, and operations decide the bill.
An example
A quote states 40,000 euros for rollout and 2,000 euros per month. What is missing: the data preparation beforehand, the business unit’s time for test cases and acceptance, the ongoing rework on results, the upkeep of the knowledge base, the re-acceptance at every model change and the person who is accountable for all of it. In the projects we have seen, this adds up regularly to more than the quoted price.
A closer look
On top of the license come integration, data upkeep, review, operations, training and the costs of errors. In AI projects the license share, in our experience, sits at the low end of the overall bill.
Why it matters
The item that most reliably goes missing is human rework — because it appears in no calculation and seeps away into existing positions. It is also the only one that can be measured before the decision: run a hundred cases through, record the pass-through rate and rework time, extrapolate. That takes two days and replaces the discussion about list prices with a number. The second regularly missing item is the cost of doing nothing — that, too, belongs in the comparison, otherwise the status quo always wins.
Commonly misunderstood
The largest overlooked item is human follow-up checking. It recurs permanently and is almost never planned for in business cases.
