Those reports fall into several

(sometimes overlapping) categories

Our (any!) reports show data. Clearly we use test (automatically special program generated) data.

We cannot use real data which i am sure you will agree with since you wold not want us to use your(!) data for our demos.

So each client needs to fill that data warehouse table with that client's data.

After that everything is ready as i explained. 

The specification for that data is very clear (since your stuff will have our test data as an example) and very similar to

denormalized state or statistical reports.

The specification is very similar to the CA SAL/SAP reports.

We will also provide pseudo-code samples for SAL/SAP business logic and flow.

So they (IT people) will need to write (or modify existing since you are already in the personal auto insurance business).
