The model description includes operation as well as billing
German compressed-air supplier Kaeser described its U.S. Sigma Air Utility model in 2017 as paying for air rather than equipment, with the provider planning, installing and operating the system. The article described a base volume and an added charge above it. Its current page distinguishes that tailored utility model from a separate preconfigured subscription offer.
These are company descriptions of service models, not disclosed terms for a particular customer or independent proof of savings, reliability or an owner’s expected return.
Say what the customer receives and how it is measured
An equipment sale and a supplied-output service answer different questions. With the service, the customer needs an agreed output at agreed conditions; the provider needs the resources and access to produce it throughout the contract. Ownership of a machine does not settle either question.
Use this ELN specification brief before asking for a price or proposing a similar offer. The technical values and obligations must come from the actual application and agreement.
| Issue | Question for the proposal | Cost or responsibility to make visible |
|---|---|---|
| Defined output | What quantity and quality, at which point and operating conditions? | Measurement method, verification and responsibility for unsuitable inputs |
| Demand pattern | What are the base volume, peaks and operating hours? | Capacity kept available even when consumption is lower |
| Equipment operation | Who runs, monitors, maintains and repairs the system? | People, energy, consumables, parts, access and backup arrangements |
| Exceptions and exit | What happens when demand changes, supply stops or the arrangement ends? | The actual response, change and removal obligations in the proposed terms |
Do not confuse a volume price with every cost being variable
Fictional planning example: a proposed annual base fee is US$24,000 and includes one million agreed volume units. A further 200,000 units at US$0.01 each would add US$2,000, giving US$26,000. These are invented tariff figures, not Kaeser rates or an engineering specification.
If use falls below the included volume, the example still has its base fee unless the proposed terms say otherwise. The provider must also check its own continuing costs; lower consumption does not automatically remove equipment funding or the team needed to support the customer. Actual metering conditions matter before comparing quotations.
Model both the quiet month and the difficult month
Ask management to show the complete annual service costs, the demand evidence and who bears an interruption or major repair under the actual proposal. Test a lower-volume period, a peak and a support incident rather than approving the average alone.
Use U.S. unit economics for the cost model and keep the draft service specification beside it. A recurring fee is useful only if it can support the operating promise your business is making.
Scope
- Company-reported historical facts are attributed. The public record does not establish private contract terms, U.S. net profit or a result another business can expect.
- ELN’s tables and decision exercises are original planning suggestions. Actual product, people, contract and operating requirements need their own checks.
Next step
In U.S. unit economics, cost the complete operating service over an annual period. Keep output conditions, base and excess volume, low-demand exposure and exception responsibilities alongside the model.
