How to measure your WhatsApp response time in an afternoon, and the number to aim for
Most owners believe they reply fast. Almost none have measured it. The gap between belief and reality is usually the after-hours and weekend enquiries, which are half the total and get answered the next morning. Here is a way to measure it in an afternoon, with nothing more than your phone and a notebook.
Quick answer
Take the last 30 new-customer conversations in WhatsApp, note the time of their first message and the time of your first real reply, and work out the median gap and the share answered within five minutes, within an hour, and after more than four hours. Research puts the biggest conversion drop after the first five minutes and again after the first hour. Most small businesses find a median above two hours once evenings and weekends are included.
The afternoon method
- Open WhatsApp Business and list the last 30 conversations started by a new customer, not by you.
- For each, note the timestamp of their first message and of your first reply that actually addresses it. An auto-reply does not count.
- Write the gap in minutes. Mark each as business hours, evening, or weekend.
- Sort the gaps. The middle value is your median. Count how many were under 5 minutes, under 60, and over 240.
- Now look only at the evening and weekend rows. That median is usually the real problem.
What good looks like
| Measure | Typical small business | Good | With an AI agent |
|---|---|---|---|
| Median first reply | 1 to 4 hours | Under 15 minutes | Seconds |
| Replied within 5 minutes | 10 to 25 percent | Over 50 percent | Nearly all |
| Evening and weekend median | 8 to 14 hours | Under 1 hour | Seconds |
| Never replied | 5 to 15 percent | 0 | 0 |
The five-minute and one-hour lines come from the Lead Response Management study and the HBR follow-up, which found businesses replying within an hour were about seven times more likely to qualify the lead than those that waited longer. "Never replied" is the number that shocks owners most; buried threads are common.
Fixing it, in order of cost
- Notifications on the right phone. Free. Many misses are simply not seeing the message.
- A useful after-hours message that gives the customer something to do. Free. See our templates.
- Shared inbox for a team so the first free person answers.
- An AI agent that answers the actual question in seconds, at every hour, and books. This is the only fix that moves the evening and weekend median to seconds. ReplyKit does it from $29 a month, with a pacing delay of a few seconds so replies feel human.
Measure again in a month
Repeat the exercise after any change. With an agent, the interesting numbers shift from response time to what happens next: how many enquiries reached Qualified, how many booked, how many were handed to a person and how long those waited. ReplyKit's leads page shows the month's new, booked, won and lost counts and the booking rate, and the Monday digest reports chats waiting for a person.
Frequently asked questions
What is a good WhatsApp response time for a business?
Under five minutes is the target the research supports; under an hour is the minimum. Most small businesses measure a median of hours once evenings and weekends are included.
Does an auto-reply count as a response?
No. Count only the first reply that addresses the customer's question.
How do I measure it without special tools?
List the last 30 new conversations, note the gap between the first message and your first real reply, and take the median. It takes an afternoon.
Why are evenings and weekends so bad?
Because customers message when they are free and businesses reply when they are open. Those hours are often half the enquiries and get the slowest replies.
How fast does an AI agent reply?
Within seconds, at any hour. ReplyKit adds a short pacing delay so replies feel natural and stay within safe limits.
