After-Call Work (ACW)

Updated on: November 5, 2026 Shaili Gupta 2 mins read

What is after-call work (ACW)?

After-call work (ACW) is the work a call center agent does once a customer interaction ends. It is also called post-call processing. Typical tasks include logging call details in a database, sending follow-up emails to the customer or another department, and scheduling any follow-up actions. Without it, a call goes undocumented and promised actions can slip through.

How to calculate ACW

ACW is measured as an average per call: divide the total time agents spend on after-call work by the number of calls they handled.

Average ACW = Total ACW time ÷ Number of calls handled

For example, an agent who spends 100 minutes on ACW across 50 calls averages 2 minutes of ACW per call.

Why ACW matters

ACW affects how efficiently a call center runs and how well it serves customers. When agents finish it quickly and accurately, issues get resolved faster and records stay reliable, which tends to lift customer satisfaction. Shorter ACW also gets agents back to the next call sooner, so they handle more calls and customers spend less time waiting in the queue.

Factors that influence ACW

Four things account for most of the variation in how long ACW takes:

1) Complex calls need more detailed documentation and more follow-up.

2) Experienced agents usually finish ACW faster than newer ones.

3) A well-configured CRM and automation tools cut the time each task takes.

4) Clear processes and solid training help agents wrap up efficiently.

How to improve ACW

Call centers can shorten ACW without cutting quality by doing the following:

Automate repetitive work such as data entry and follow-up emails.

Train agents thoroughly on the ACW process and the tools they use.

Streamline workflows by removing steps that add time but not value.

Review ACW metrics regularly to see where the time goes, then adjust.

Average handle time (AHT): the total time spent on a call, including talk time and ACW.

First call resolution (FCR): the percentage of calls resolved on the first contact, with no follow-up needed.

Customer satisfaction (CSAT): a measure of how satisfied customers are with their interactions with the call center.

Conclusion

ACW happens after every call, so it shows up in both agent productivity and customer satisfaction. Tracking average ACW per call and trimming it through automation, training and simpler workflows is a practical way to improve both.
