Definition
After-call work (ACW) is the wrap-up a customer support agent completes after the caller hangs up, such as writing notes, updating the customer record, choosing a call outcome and scheduling follow-ups. It is counted as part of handle time.
How after-call work works
When the caller hangs up, the human agent’s phone system puts them into a wrap-up state. In that state no new call is routed to them, and a timer runs. They write the case notes, update the customer record, set a disposition (the label for how the call ended), and start any follow-up such as a refund or a callback. When they finish, or a time limit runs out, they return to available.
Many platforms report this as “wrap-up time” or “after-call work time”. It is one of the three parts of average handle time, next to talk time and hold time, and it often makes up a large share of it on calls that need records.
The metric is simple to measure and easy to misuse. A hard cap on wrap-up time pushes agents to leave notes short or empty, and the cost shows up later when the next agent reads a record that says nothing. A very long wrap-up can mean the agent has to search in several systems because nothing is filled in automatically. Both are signals about the tools, as much as about the person.
For a team that pays by the hour, the arithmetic is direct. 90 seconds of wrap-up on each of 1,000 calls a day is 25 hours of paid time a day (90 x 1,000 / 3,600).
Why it matters for voice agents
A voice agent can write to the customer record during the call by calling tools, and it can produce a summary and an outcome label as the call ends. That removes most of the wrap-up for calls it handles alone. It is one of the clearer ways an agent lowers cost per call.
It is not free of risk. A generated summary can be wrong, and a record the agent wrote itself is only as good as its tool calls. Someone should sample summaries against the recording or transcript.
The case that remains is the transfer. When the agent hands a call to a person, wrap-up still happens for the human portion, and a clear handoff summary saves the person from asking the caller to repeat. See agent assist for the opposite setup, where AI helps the human instead of replacing the first leg of the call.
Example
An illustrative human-handled call (invented numbers): 5 minutes of talk time, then 2 minutes of wrap-up for notes and a refund request. Wrap-up is 2 of the 7 minutes of handle time, or about 29%.
