How far should AI go in customer support and success? — CRO AI Momentum

When it comes up

When support costs rise, when a vendor proposes a customer agent, or when renewal teams are stretched.

Your options

AI assists human agents and CSMs

Fits when: Complex products, high-value accounts, or customers who expect a person.

Watch out: Productivity gains depend on training and workflow; measure them.

AI agent for routine questions with human hand-off

Fits when: High volumes of routine questions with clear, documented answers.

Watch out: Accountability for wrong answers, hand-off speed, customer preference for humans.

AI-first service with minimal humans

Fits when: Very simple, low-value interactions where customers prefer speed.

Watch out: Quality and retention risk; public backlash if customers can't reach a person.

How to decide

Segment interactions by value and complexity. Use agents for routine, well-documented questions; keep humans for complex, sensitive and high-value accounts; use AI to make humans faster everywhere. Measure retention, satisfaction, hand-off time and complaints — not only deflection — and decide what the agent may commit to.

Trade-offs

Agents lower cost per contact and give instant answers but create accountability and preference risks; human-led service protects relationships but costs more; assistive AI is lower risk but its gains are smaller per contact.

Real examples

Air Canada (2024 BCCRT 149), a tribunal held Air Canada responsible for wrong information its website chatbot gave a customer, rejecting the idea that the chatbot was responsible for its own actions.

What to check first

Which question types make up most volume, and whether approved answers exist for them.
What the agent would be allowed to commit to (refunds, credits, changes) — ideally nothing without rules.
Retention and satisfaction baselines for the accounts the agent will serve.
