Roll out an AI support agent in 90 days: confidence thresholds, human handoff and cleaning up the help center
A vendor's write-up of a 90-day support automation test at a SaaS company: staged rollout, a confidence threshold for human review, and fixing outdated docs before the AI could resolve most tickets.
Evidence: The author reports this. We have not checked it beyond reading the source.
The business problem
A growing SaaS handling about 5,000 tickets a month wants faster replies and lower cost per resolution without damaging customer trust through wrong answers.
What was tried
In weeks 1 to 4 the AI was connected to the help center and existing response macros and given about 10% of authenticated traffic. In month 2 it took all traffic and more ticket types, Slack was added for internal escalations, and answers below a 0.85 confidence threshold went to a human. In month 3 outdated articles were removed, tone was adjusted from satisfaction feedback, and the system was linked to CRM and order data so it could answer account-specific questions. A multi-agent setup (classification, policy checks, routing) and escalation on frustration cues were added later.
What was reported (positive)
The vendor reports AI resolution rising from 45% in month 1 to 65% in month 2 and 80% in month 3, first response time falling from 1m 12s to 4 seconds, cost per resolution falling from $3 to $7 to about $1, and 'I don't know' answers dropping from 30% to under 10%.
Limitations
This is the vendor's own test of one unnamed company, with no control group or method described, and the AI platform used is not named. The $1 cost has no breakdown and may exclude setup. Hallucination rates of 3% to 27% were reported in month 1, and billing disputes and third-party integration questions were hard for the AI. It needed outdated documentation fixed and live order data connected, plus staff time to review conversations. It also mixes in unverified figures from other companies.
What you need
A helpdesk with ticket history (Zendesk is mentioned), a current help center, response macros, access to order or customer data, escalation rules, and staff time for review and tuning. Costs and ramp-up time are not stated.
