An ecommerce company wants to quantify the chatbot’s financial impact on operations. Which metric directly measures cost per customer interaction?

Cost for each customer conversation" directly measures the financial impact per interaction by calculating the total cost associated with running the chatbot divided by the number of conversations it handles. This metric provides a clear understanding of the chatbot's efficiency and cost-effectiveness. "Number of customer inquiries handled" is a volume metric, not a cost metric. "Cost of training AI models" is an upfront investment cost, not a per-interaction operational cost. "Average handled time (AHT)" measures efficiency in terms of time, not financial cost.
