I have not noted any ROI statistics.

ROI is something that the client takes care of, and I think they must be keeping track of it and getting a certain result indicating a good ROI. So, that's why they may have continued using it over the years.

The product has proven to be exceptional and highly competitive in the market. As a result, I have experienced substantial financial success with the product. There are many examples we have for the ROI.

Depends on the project.

The main problem of this project is they are trying to move the old solution to production in order to begin getting return on investment.
