What a missed call actually costs a service business
Missed calls are usually counted as a nuisance. Here is how to work out what yours are worth in money, using numbers you already have.
Most owners know they miss calls. Almost none of them know what it costs, because the loss never appears on a statement. Nobody invoices you for the job you did not win. The money just does not arrive, and the month looks slightly worse than the last one for no reason you can point at.
The arithmetic is not complicated, and you already have every number in it.
The four numbers you need
- Calls you miss per week. Your phone system reports this. If it does not, count for one week by hand.
- The share of callers who would have become customers. Use your normal close rate on inbound enquiries. Most trades businesses know this within a few points.
- Average job value. Not your best job. The median one.
- Repeat rate. How often a first job becomes a second. This is the number people forget, and it is usually the largest term.
Multiply the first three and you have the immediate loss. Multiply by the fourth and you have the real one.
A worked example
Take a plumbing company missing 12 calls a week. Say a third of inbound callers would have booked, and the median job is $340. That is 12 × 0.33 × $340, or about $1,350 a week. Call it $70,000 a year in first jobs alone.
Now add repeat work. If a first-time customer returns on average 1.4 more times over three years, the same missed calls are worth closer to $168,000 across that period. The first number is the one people quote. The second is the one that actually left.
Where the calls actually go
A missed call is rarely a lost customer. It is a customer who phoned someone else ninety seconds later. Service buyers are not loyal at the point of first contact — they are solving an urgent problem and working down a list. Whoever picks up gets the job.
This is why voicemail performs so badly. It converts an urgent caller into a task they have to remember to complete, at a moment when the alternative is dialing the next number. The message is not the product. Picking up is.
The three periods that leak most
- Evenings and weekends. For emergency trades this is often the highest-intent traffic of the week, and it is exactly when nobody is at a desk.
- The mid-afternoon crush. One person is on another call, another is driving, and three calls land in six minutes.
- Holiday cover. A week where nobody is watching the line can quietly cost a month of margin.
What to do with the number
Once you have a figure, the decision becomes an ordinary business comparison rather than a technology question. If missed calls cost you $1,350 a week, then anything that recovers even half of them for a few hundred dollars a month is not a close call.
It also tells you when the answer is no. If you miss two calls a week and your median job is $120, the recovered revenue does not justify anyone's monthly fee, and you should spend the attention elsewhere. Working out the number protects you from the wrong purchase as much as it justifies the right one.
If your figure is large enough to act on, an AI receptionist is one way to close the gap — it answers on the first ring at any hour, books the job, and texts you what happened. The point of the arithmetic, though, is that you should know what the gap is worth before anyone sells you anything to fill it.
