The total time taken to fully resolve a customer's issue

What is Resolution Time?

Resolution time (also called time to resolution or TTR) measures the elapsed time from when a customer first contacts you to when their issue is fully resolved and the conversation is closed. Unlike average handle time (which measures agent work time), resolution time includes all waiting periods—time between replies, internal escalations, and any back-and-forth needed to reach a solution.

Resolution time is measured differently across channels. For live chat, it might be 10-20 minutes. For email, a few hours to a few days. For complex technical issues requiring engineering involvement, it could be weeks. Most teams track median resolution time rather than average, since a few outlier cases can skew the average significantly.

Why Resolution Time Matters

Zendesk research found that 72% of customers who gave negative satisfaction ratings cited slow resolution as the primary reason. Customers can tolerate a fast first response followed by a reasonable resolution timeline, but extended back-and-forth without progress erodes satisfaction rapidly.

Tracking resolution time by issue type reveals which problems need better documentation, tooling, or training. If "billing questions" resolve in 5 minutes but "integration issues" take 3 days, that tells you where to invest in better self-service resources or agent training.

Resolution Time in Practice

A team tracked their resolution times and found that conversations requiring escalation to engineering took an average of 4.2 days. The bottleneck was context transfer—engineers had to ask customers to re-explain the problem. By adding structured internal notes (steps to reproduce, error messages, customer environment details) to the escalation workflow, they cut engineering resolution time to 1.8 days. Customer satisfaction for escalated issues improved from 58% to 79%.

Frequently Asked Questions

For live chat and messaging: under 30 minutes. For email: under 24 hours. For complex technical issues: under 3 business days. These are general targets—your benchmarks should be based on customer expectations in your industry and the commitments in your SLAs.
First response time measures how quickly you acknowledge the customer. Resolution time measures how quickly you fully solve their problem. A 2-minute FRT with a 3-day resolution time means you're fast to respond but slow to resolve—both metrics need attention.
Common causes: waiting for customer replies (send clear next-step requests), internal escalation delays (improve handoff processes), agent knowledge gaps (build better documentation), and complex issues requiring multiple departments (create cross-team workflows).
