Hi Michael,
Sorry, cant help you with any statistics, but something else you might want to consider for your business case is PCI DSS compliance. By moving the whole credit card authorisation process to an automated system and removing the agent interaction, you can eliminate the PCI data protection concerns. It also means that you dont have to mask or encrypt your call recordings as IVR transactions are not normally recorded.
Whether you can apply a "cost benefit" to this compliance, I am not certain, but its worth considering.
Hope this helps,
