What percentage of calls do small businesses typically miss?

Industry research suggests small businesses miss between 20 and 40 per cent of incoming calls on average. For sole traders and very small teams, especially during busy periods or outside business hours, the figure can be significantly higher.

Do customers call back if a small business misses their call?

Most do not. Research consistently shows that the majority of callers who reach voicemail do not leave a message, and a large proportion will simply call a competitor. The first business to answer usually wins the customer.

When are small businesses most likely to miss calls?

The highest-risk times are before and after business hours, during peak service periods when staff are occupied, on weekends and public holidays, and during lunch breaks or shift changes. These gaps are predictable and can be planned for.

What is the most cost-effective way for a small business to stop missing calls?

For most small Australian businesses, an AI phone receptionist offers the best balance of coverage and cost. A full-time human receptionist can cost $55,000 or more per year, while AI answering services like ELLIE start from $199 AUD per month and answer calls 24 hours a day, 7 days a week, including weekends and public holidays.

How Many Calls Do Small Businesses Miss?

If you run a small business in Australia, missed calls are almost certainly costing you more than you think. Not just in the occasional lost booking, but in a steady, invisible drain on revenue that most owners never sit down to calculate.

This article pulls together what we know about missed call rates, why they happen, and what the real consequences look like for Australian businesses.

The Scale of the Problem

Industry research consistently suggests that small businesses miss between 20 and 40 per cent of incoming calls. For a sole trader or a team of two or three, that figure can climb even higher during busy periods, when staff are with clients, or outside business hours.

Think about what that means in practice. If your business receives 50 calls a week and you miss a third of them, that is roughly 17 potential customers each week who reached voicemail, heard silence, or simply gave up. Many of them will not try again.

Research into consumer behaviour suggests that the majority of callers who reach voicemail do not leave a message, and a significant portion will call a competitor instead. The customer who hung up without leaving a message is invisible to you, but they are very real to whoever answered their next call.

When Are Businesses Most Likely to Miss Calls?

Missed calls cluster around predictable times. Understanding when they happen is the first step to doing something about them.

Before and after business hours: Many Australians call early in the morning or in the evening after work. If your phones only operate from 9 to 5, you are unavailable during some of the most convenient calling windows for your customers.
During peak service periods: Trades, salons, medical practices and hospitality businesses all experience rushes where staff simply cannot get to the phone. A plumber on a job site, a beautician with a client in the chair, a cafe owner during the breakfast rush , none of them can answer a ringing phone.
On weekends and public holidays: In Australia, long weekends and school holidays often generate spikes in consumer inquiries, precisely when many small businesses have reduced or no phone coverage.
During lunch breaks and handover periods: Even fully staffed offices have gaps. Lunch breaks, team meetings and shift changes create windows where no one is at the phone.

If your business fits into any of these categories, the 20 to 40 per cent missed call estimate may be conservative. Some sole traders report missing the majority of their calls on certain days.

What Does a Missed Call Actually Cost?

This depends heavily on your industry and average job value, but the maths is worth doing for your own business.

Suppose your average new customer is worth $300 in their first transaction, and a reasonable number convert to repeat clients over time. If you miss 15 calls a week and even a third of those were genuine inquiries, you could be walking past thousands of dollars in monthly revenue without realising it.

For higher-value industries like legal services, construction, or healthcare, the number is even more confronting. A single missed call from a prospective client in a professional services firm could represent thousands of dollars in lost work.

There is also a brand cost that is harder to quantify. When a customer cannot reach you, they form an impression about how your business operates. In competitive local markets, that impression matters.

Why Traditional Solutions Fall Short

The obvious answer to missed calls is to hire a receptionist. But a full-time receptionist in Australia typically costs $55,000 to $70,000 per year in salary alone, before you add superannuation, leave entitlements and training. That is a significant commitment for a small business, and a receptionist still cannot answer calls at 7pm on a Sunday.

Voicemail is the most common fallback, but as noted above, most callers do not leave messages. You are not actually capturing the inquiry, you are just softening the blow slightly.

Answering services and virtual receptionist arrangements are a middle ground, but they vary widely in quality and often involve scripted responses that feel impersonal. For more on how these options compare, see our breakdown of virtual receptionist vs answering service options.

For businesses in specific industries like real estate, trades or beauty, the missed call problem is particularly acute. Our articles on handling business calls on a job site and stopping missed calls at your salon go into more detail on industry-specific approaches.

What Callers Do When No One Answers

The short answer is: they move on. Research into consumer behaviour consistently shows that when a business does not answer, most callers will not try again. They will search for an alternative, and your competitor who does answer the phone gets the job.

There is more detail on this in our article on whether customers call back if no one answers, but the core finding is consistent: the business that answers wins the customer, and the one that does not rarely gets a second chance.
