Call-center voice AI: calculate cost per resolved request

A call center should compare the cost of resolving a request, not just the cost of an automated minute. An assistant can reduce talk time while increasing repeat calls or staff rework. The financial model needs to capture both.

Establish the baseline

Choose one call reason and a defined observation period. Record attempted and answered calls, verified resolutions, repeat contacts, staff handling time and relevant operating expenses. Keep the definition of resolution consistent before and after the change.

Cost per resolved request = attributable operating cost ÷ verified resolved requests
Incremental net benefit = avoided expense + attributable added contribution − added cost

Added cost includes setup, integrations, platform/provider usage, telephone legs, recurring numbers and staff review. Reassigned staff time is capacity gained unless an actual expense is avoided. The ROI worksheet provides an explicit first-year example.

Choose a bounded pilot

Public information or structured request capture may be easier to evaluate than account mutations. A common call reason is not automatically low risk. Define authorization, allowed actions and the person responsible when the assistant cannot finish.

Test corrections, unknown answers, failed tools and the actual telephone route. If transfers matter, test accepted, declined and unanswered destinations. A browser demonstration or text evaluation does not establish those outcomes.

Review capacity and recovery

Estimate peak simultaneous calls and verify limits across the carrier, model provider, worker and connected systems. Do not assume unlimited scale, automatic failover or a shadow mode that has not been implemented. Use the bounded load plan after sequential acceptance.

Expand from evidence

Review caller feedback, unresolved requests, repeat contact and staff rework alongside cost. Keep the previous route available with an accountable rollback owner.
