How Much Missed Calls Cost Plumbers: A Worksheet

Missed calls cost plumbers the jobs those callers would have booked, plus the repeat work and referrals that would have followed, and you can put a dollar figure on it with three of your own numbers. Nobody else's average matters here. Your call log, your booking rate and your job size tell you what the phone is costing you. This post gives you the worksheet, then the options for fixing it.

The call you miss is the one you never see

You are under a kitchen sink in Etobicoke with both hands full. The phone buzzes in your pocket. You let it go. By the time you climb out, wash up and check, there is a missed call and no voicemail.

That is the expensive part. A missed call with a voicemail at least gives you a name and a problem. A missed call with no message gives you a number and a guess. You call back. Nobody picks up, or they say "we already got someone, thanks."

You never find out what that job was worth. It does not show up on any report. It just never happens, so it is easy to believe it costs nothing.

It happens in a few predictable places in a plumber's day:

• On a job, when stopping to answer means stopping the work.
• Driving between jobs, where answering is unsafe or illegal.
• At the supply house, at the counter, with a line behind you.
• Evenings and weekends, when you are with your family or asleep.
• The middle of the night, when the call is a burst pipe or a backed-up drain.

Some of these calls are tire-kickers or price shoppers. Some are the best jobs of the month. From the missed call list, you cannot tell which is which.

Work out your own number

Here is the worksheet. Use your numbers, not ours, and not an industry average from a sales page. You need three figures.

A: calls you miss in a week. Open your phone's recent calls list or your carrier's online call log. Pick one ordinary week. Count every missed or unanswered call from a number that is not spam, family or a supplier. If you have a part-time person on the phone, count what reaches voicemail on their side too.

B: share of those callers who would have booked. Look at the calls you did answer in that same week. Out of every caller you spoke to, how many turned into a booked job? That is your booking rate. Be honest. If you book about half the people you talk to, B is a half. If you book most of them, use that. Missed callers are not likely to book at a better rate than answered ones, so do not inflate it.

C: your average job. Take your invoices from the last few months. Add them up and divide by the number of jobs. Leave out the one huge renovation that skews it. You want an ordinary service call, not your best day.

Now multiply:

A × B × C = what missed calls cost you in a week.

Then multiply that by the number of weeks you work in a year. That is the annual figure. Write it down somewhere you will see it.

What the worksheet leaves out

The A × B × C number is the floor, not the ceiling. It only counts the first job. It leaves out:

• Repeat work. A homeowner whose water heater you replaced calls you again for the next leak. A missed first call means no second call.
• Referrals. A good job on one street turns into calls from the neighbours. A missed call sends that whole chain to someone else.
• Reviews. The plumber who answered gets the review. You get nothing.
• Emergency premiums. If you charge more after hours, and your missed calls cluster at night and on weekends, your C for those calls is higher than your daytime average.

If you want a sharper number, run the worksheet twice: once for daytime calls and once for after-hours calls, each with its own B and C.

Why the callback does not save you

You probably call everyone back. That is good practice. It is not the same as answering.

Think about what the caller does after they hit voicemail. They have a problem now. They have a list of plumbers from a search or a neighbourhood group. You were one name on that list. When you do not pick up, the simplest thing for them to do is call the next name. If that plumber answers and gives a time, the decision is made before you climb out from under the sink.

A callback reaches a caller who has already moved on, or one who is now comparing two quotes instead of one. Either way, the odds are worse than if you had picked up. You do not need a statistic to see that. You just need to remember the last time you called a trade, got voicemail and dialled someone else.

Your options, side by side

There are a handful of ways to cover the phone. Each one has a real cost and a real gap. The point of the worksheet is to compare those costs against your own missed-call number.

None of these is free. Voicemail looks free until you run the worksheet. A family member answering looks free until they are away or tired of it. A live answering service is a fair choice for some shops. Compare what each one will actually do with the call, not just whether someone says hello.

If you want the longer version of that comparison, see our page on a plumbing answering service.

How an AI receptionist handles the same call

Here is what that sink-side call looks like when an AI receptionist answers instead of voicemail. This is a role-play on our demo line, +1 (647) 492-9272, which answers as Harbourline Plumbing & Drain, a fictional plumbing company. The caller and the job are fictional.

AI assistant: Thanks for calling Harbourline Plumbing & Drain, this is their AI assistant. What's going on?

Caller (fictional): My basement floor drain is backing up. There's water coming out of it.

AI assistant: Okay. Is the water still rising, or has it stopped?

Caller (fictional): It's slowed down, but it's not draining.

AI assistant: Got it. What's the address?

Caller (fictional): It's on a street in Mississauga, near the plaza.

AI assistant: And the best number to reach you?

Caller (fictional): This one.

AI assistant: I have an opening this afternoon. Does that work?

Caller (fictional): Yes, please.

AI assistant: You're booked. You'll get a confirmation. In the meantime, avoid running water or flushing toilets in the house so it doesn't get worse.

While that happens, you are still under the sink. The job lands in your calendar, Google Calendar or Outlook, in a slot you left open. The call is logged in your CRM so you can see who called, what they needed and what was booked. You climb out to a booked job instead of a missed call.

That is the whole difference. Same caller, same problem, same moment. One version ends in voicemail. The other ends in a booking.

A few plain facts about how ours works:

• The AI receptionist answers 24/7, including nights, weekends and holidays.
• You keep your number. You set up call forwarding. Nothing is ported.
• Setup is live in a day.
• It books into Google Calendar or Outlook. Exports to Jobber, Housecall Pro or ServiceTitan are available on request.
• English today. French and other languages are being added.
• It is $749/month CAD, month to month, cancel anytime. The first 7 days are free.

What to do this week

You do not need to buy anything to start. Do these in order.

1. Count your missed calls for one week. Use your phone and your carrier's call log. That is A.
2. Work out your booking rate. Out of the callers you spoke to that week, how many booked? That is B.
3. Pull your average job from invoices. Leave out the outliers. That is C.
4. Multiply A × B × C. Write down the weekly and yearly figure.
5. Split by time of day. Mark which missed calls came during jobs, while driving and after hours. That tells you where the gap is.
6. Compare against the cost of each option. Use the table above. Put your weekly figure next to each option's real cost.
7. Test before you commit. Call the demo line and play a difficult customer. Listen to how the call is handled, then decide.

If your weekly number is close to nothing, you may not have a phone problem. Good. Spend your time elsewhere. If it is larger than you expected, you now have a number to make the decision with, instead of a feeling.

When this is not the right fix

An AI receptionist is not for every shop. Be straight with yourself about these:

• You genuinely answer almost everything. If your worksheet shows A is tiny, a new answering setup will not move much.
• Your booking rate is low for other reasons. If B is low because your prices, reviews or service area are off, answering more calls will not fix that. Fix B first.
• Your callers need French today. The AI receptionist speaks English today. French is being added, but if most of your work is in French right now, wait or use a person.
• You want every call screened by a human. Some owners want a person on every call, full stop. That is a fair choice. A live service or office staff will suit you better.

If you are in the GTA and want to see how this works for a shop like yours, see our page for Toronto.

The worksheet is the useful part. Run it this week with your own call log and invoices. Whatever the number is, you will know what the phone is costing you, and you can decide what it is worth to fix.
