FAQ

Many chat teams aim for a first reply in under a minute during business hours. Pick a target you can actually staff rather than one that looks good on paper.

  • Chat expects speed. A visitor on your site is waiting; a minute feels long, while email tolerates hours.
  • Staff the target. Check how many chats your team can take at that speed before promising it.
  • Measure attainment, not average. The estimator counts replies within target versus total, which is what an SLA promises.

Real first response time is tracked on the analytics page.
