How much do missed calls really cost a Canadian small business? (2026 data)

Ask any Canadian small-business owner whether they miss calls and they'll shrug and say sometimes. Ask them what those calls are worth and most won't have a number. That gap — between casually knowing the problem and putting a dollar figure on it — is where most service businesses quietly leak revenue every month.

Here's the back-of-envelope math, with real Canadian numbers, for a handful of common service industries.

The formula every owner should know

Cost of a missed call = P(call results in a job) × average job value.

The first factor is the part owners underestimate the most. When someone calls a plumber, they aren't cold-shopping — they have a problem that needs solving today. Industry surveys consistently put the "goes to voicemail and never calls back" rate around 75-80%. The caller has 4-5 other Google results open in adjacent tabs; the next one that answers wins the job.

80% of callers who reach voicemail don't leave a message — they hang up and call the next business on the list.

What a missed call costs by industry

Job value varies wildly by trade, but the unit math is the same. Multiply the conversion rate by the average ticket and you get the expected value of one missed call.

Those are expected values per inbound call, blended with the conversion rate. So if a plumbing business gets 30 calls in a month and misses 10 (conservative — most owners admit to missing more), the bill comes to:

10 missed calls × $380 expected value = $3,800/month in forgone revenue. $45,600/year. From a phone problem.

For dental practices the lifetime-value math is bigger but the miss rate is usually lower; for salons the average ticket is smaller but the cumulative miss rate is higher because so many salons run with only one front-desk staffer.

The after-hours hole

Even the best human receptionist works business hours. Roughly 40% of inbound service-industry calls land outside 9-5 — early mornings, evenings, weekends — and the modal outcome of those calls is voicemail. A handful go to forwarded cell phones where the owner answers in a kitchen at 9pm and offers to call back tomorrow. Most never reach a human at all.

Those after-hours calls also have the highest urgency — a leak, a toothache, a Saturday-morning appointment request — which means they convert at higher rates when actually answered. Skipping them isn't a small loss. It's the most valuable slice of your funnel.

What it costs to fix

For decades the only way to plug this hole was a human answering service. Those run $200-$500/monthin Canada, and they take a message — they don't book the appointment, can't access your calendar, and don't know your prices. The caller still has to be called back. Half of them have already booked with someone else by then.

AI receptionists like Cedri handle the call end-to-end for $29/month: pick up in one ring, ask the questions a human would, check your live calendar, book the slot, text both sides a confirmation. The caller hangs up with a real appointment, not a callback promise.

How to measure your own number

If you want the real number for your business, not an industry average, three things will get you close:

• Pull last month's call log from your phone provider. Count inbound calls that were never answered or went to voicemail. Most VoIP providers (RingCentral, GoTo, etc.) export this as CSV.
• Multiply by your real conversion rate.If you don't know it, assume 20-25% of inbound calls would have converted to jobs — that's the industry average for service businesses with decent reviews.
• Multiply by your average job value. Pull from your bookkeeper, your QuickBooks revenue, or just the average of your last 50 invoices.

The product of those three numbers is your monthly miss tax. Most owners are surprised. Most owners then go quiet for a minute. Then they fix it.
