> its going to save the clerical staff hundreds of hours per year

How many hundreds of hours is your team spending to get there? What is the ROI on this vs investing that money elsewhere?

Can't speak to the financial benefit over other investment. Total dev/testing time looks to be fairly small in comparison to time saved in even one year, although with different salaries etc I cannot be too certain on the money ratio. Ultimately not my direct concern, but those making decisions are very happy with results so far and looking for additional processes to apply this type of system to.
