Zero-Touch Resolution

Zero-touch resolution is a conversation where the customer's problem was solved, and no human was involved at any point. It is the strictest member of the resolution metric family, and the one most often quoted without saying which conversations were excluded from the count.

How Zero-Touch Resolution Fits the Metric Ladder

When buyers compare AI ticket deflection tools, these five measures appear together, although each uses a different finish line.

Self-service rate counts people who use or finish help content, portals, chatbots, or automated workflows under the reporting method.
Deflection rate counts contacts that never reach a human queue, even when the customer may not have received a useful answer.
Containment rate counts automated conversations without a human transfer, even if customers leave before their problem is solved.
Resolution rate counts issues marked as solved, whether the work came from an AI agent, a human agent, or both.
Zero-touch resolution counts only solved conversations with no human reply, approval, correction, manual action, or live takeover.

Illustration of How Zero-Touch Resolution Fits the Metric Ladder

Zero-touch resolution is the strictest metric because the customer's problem must be solved without human involvement at any point.

How to Calculate Zero-Touch Resolution

Zero-touch resolution rate = zero-touch resolved conversations ÷ all eligible conversations × 100

The numerator includes conversations solved without human help or repeat contact about the same issue, while the denominator includes every eligible and excluded group.

An AI-written answer sent by a human may count as resolved but not as zero-touch, while a contained conversation also fails when the customer leaves without a solution.

How Fin and Wonderchat Measure Their 76% Resolution Figures

In June 2026, Fin, formerly Intercom, reported about 76% resolution without human involvement, while Salesforce's agreement to acquire Fin was still pending. Fin divides resolved conversations by those where it had an opportunity to answer and excludes constrained conversations.

Wonderchat's cleared figure is also about 76% over a rolling 30-day window, using resolved ÷ (resolved + unresolved) after unclear conversations are excluded. Customer feedback takes priority, while an AI judge scores conversations without feedback, and live-agent or workflow resolutions may count.

The definitions and eligible populations differ, so the figures are not interchangeable. Wonderchat states which conversations a rate excludes.

Frequently Asked Questions

What is zero-touch resolution?

Zero-touch resolution means automation solved the customer's problem from beginning to end without any human reply, approval, correction, or manual action.

How is it different from resolution rate?

Resolution rate may include human work, while zero-touch resolution covers only solved conversations that did not involve a person.

What counts as human involvement?

A human reply, approval, edit, manual action, or takeover counts as involvement, while later analytics reviews do not affect the classification.
