What it is
The calculation layer of a cost-of-service study, built once against your own method. Cost pools, allocation factors, units of service, and the rate design that recovers the revenue requirement, with every client-specific input on one tab and the calculation tabs referencing only that tab.
It is your method, not ours. We do not have a house allocation and we are not trying to sell you one.
What you hand us
Your class structure, your cost pools and the allocation factors you already use. If you have a model you like, hand us that: refactoring an existing one so its inputs are separable is usually faster than starting over and always easier to check.
What you get back
A workbook or a module, with an inputs tab, a documented calculation path from cost pool to rate, and a test that reproduces a study you have already published. That last part matters — a model that cannot reproduce a result you have defended is a model you cannot use.
What it is built from
Nothing of ours. This is built from your method and your figures. Where the study also needs filed public data — a peer set, a loss figure — that comes from the corpus and carries its own citation.
What it does not do
It does not decide the allocation. Which costs are demand-related and which are commodity-related is a professional judgment you are paid for, and a module that made it for you would be answering the question you were hired to answer.
It does not produce the study. It is the arithmetic under a study; the narrative, the exhibits and the recommendation are yours.
It is not a product with a license. It is built for one firm’s method, and we do not resell it.
