After call work (ACW) / wrap time
After call work is the time an agent spends on post-call tasks before they become available for the next contact. It is a direct component of AHT — and through AHT, a driver of your Erlang C agent count. Reducing ACW is one of the fastest levers on headcount without changing service level or volume.
ACW in the AHT formula
AHT components
Talk time
4:00
Agent speaking to customer
Hold time
0:45
Customer waiting, call active
ACW / wrap
1:15
Post-call tasks, call ended
Total AHT
6:00
4:00 + 0:45 + 1:15
ACW represents 20.8% of total AHT in this example. Reducing ACW from 1:15 to 0:45 — a 30-second improvement — reduces AHT from 6:00 to 5:30, an 8.3% improvement. At 100 calls/hour, this typically saves 1–2 agents. Use the AHT impact calculator to model your specific scenario.
What ACW typically includes
CRM and case notes
- →Contact summary note
- →Call outcome / resolution logged
- →Next action or follow-up scheduled
- →Account update (address, preference)
Process and fulfilment
- →Order raised or updated
- →Refund or credit processed
- →Referral or escalation logged
- →Callback scheduled in WFM system
Compliance
- →Disclosure log completed
- →Recording flagged for QA
- →Vulnerable customer marker
- →Complaint formally registered
Communication
- →Confirmation email sent
- →Internal handoff note
- →Third-party notification (e.g. claims team)
- →Letter or correspondence triggered
ACW benchmarks by contact type
ACW above 5 minutes for standard contacts typically signals a process or systems problem — agents cannot find the right CRM field or are navigating disconnected systems, not consciously extending wrap time.
Single CRM field update; low process complexity
Multiple field updates across systems if not integrated
Case note + action; moderate complexity
Compliance log + disclosure record + CRM update
Policy system update + document trigger + compliance
Complex intake form; mandatory data collection; multiple systems
Complaint form, regulatory categorisation, next-action scheduling
Ticket creation, fault logging, escalation note
ACW reduction techniques — ranked by impact
CRM screen-pop with pre-populated fields
Very high impactIf the CRM automatically populates contact summary fields from call metadata (queue, duration, IVR path, account number verified), agents spend zero time entering data they didn't gather — they only confirm and add unique information. Screen-pop that pre-fills the contact type, product touched, and a suggested outcome field can reduce ACW by 40–60% for straightforward contacts.
Post-call guided workflows
High impactA post-call screen that presents only the fields relevant to this contact type (driven by IVR path or call classification) prevents agents from navigating a full CRM to find the right section. Sequential guided workflows reduce cognitive load and navigate ACW steps faster. Completion rates are also higher — agents are less likely to skip fields when guided linearly.
Single-system integration
High impactACW time often doubles when agents must update more than one system (CRM + order management system + billing system). Integrating updates through a single interface — or using a desktop layer that pushes updates to multiple back-end systems simultaneously — removes system switching time. Even a 30-second system switch per update compounds across hundreds of agents.
Templated note structures
Medium impactContact note templates for common contact types (complaint, refund, address change) allow agents to select a template and fill in only the unique information rather than writing free-text notes from scratch. Template discipline also improves note quality and consistency for downstream teams.
Speech-to-text note transcription
Medium impactTools that transcribe call audio to auto-generate a contact summary draft reduce free-text typing time. Agent reviews and corrects rather than writes from scratch. Accuracy varies by product and accent — review the error rate before rolling out to assess whether correction time exceeds typing time.
ACW cap (maximum wrap time) in ACD
Low–Medium (risk) impactSetting a maximum ACW time in the ACD (e.g. 120 seconds, after which the agent is automatically returned to available) creates urgency — but also creates a perverse incentive to rush notes and skip compliance steps. ACW caps are controversial and typically harm FCR when agents defer follow-up tasks. Use only with close monitoring; never cap compliance-mandatory ACW.
ACW and schedule adherence
Extended ACW is one of the most common causes of below-target schedule adherence — agents in wrap are not available in the ACD queue and do not count as adherent to their scheduled availability.
Legitimate ACW
Agents completing genuine post-call tasks — CRM update, compliance log, fulfilment action — are in legitimate ACW. This time is correctly captured in AHT and does not represent an adherence problem. It is a process efficiency opportunity, not a behaviour problem.
ACW as recovery time
In high-occupancy operations (>88%), agents occasionally extend ACW deliberately to recover between calls. This is a sign that occupancy is too high — the agent has no other recovery mechanism. The fix is to lower occupancy, not to discipline the behaviour. Disciplining recovery-ACW in a high-occupancy operation accelerates burnout.
ACW questions
What is ACW (After Call Work) in a contact centre?
ACW is the time an agent spends on post-call tasks (CRM updates, case notes, fulfilment actions, compliance logs) after the call has ended and before they become available for the next contact. AHT = talk time + hold time + ACW. ACW is a direct component of AHT and therefore of agent headcount via Erlang C.
What is a good ACW target for a contact centre?
Simple transactional contacts: 30–60 seconds. Moderate complexity: 60–120 seconds. Complex regulated contacts (insurance claims, formal complaints): 2–8 minutes. ACW above 5 minutes for standard contacts usually signals a process or systems problem — agents navigating fragmented CRM screens rather than taking excessive time deliberately.
How does ACW affect staffing levels?
ACW is a component of AHT which is the primary input to Erlang C alongside call volume. Reducing ACW reduces AHT which reduces agent requirements at the same service level. Example: 100 calls/hour, AHT reduces from 6:00 to 5:30 (30s ACW reduction) — typically saves 1–2 agents. Across a 100-agent operation, a 30-second ACW reduction can save 5–8 agents (~£500k/year).
What is the difference between ACW and hold time?
Hold time: customer is waiting on an active call while the agent performs a task. ACW: the call has ended, the customer has disconnected, but the agent is completing post-call tasks. Both contribute to AHT. Hold time is reduced by improving system access speed and knowledge; ACW is reduced by improving CRM workflow and reducing post-call task burden.
