Is an answering service worth it? Do this math first

"Is it worth it?" is a harder question than "what does it cost?", and it's the one that actually decides whether you sign up. The good news is it's answerable with arithmetic you can do on the back of an invoice — using your numbers, not an industry average.

There's only one thing you need to work out: how many jobs the service has to save you each month before it pays for itself. Everything else is detail.

The break-even calculation

Take the monthly cost of the service. Divide it by the profit you make on a typical job — not the invoice total, the profit after parts, fuel, and your time. That's your break-even number.

Say a service runs you $200 a month and you clear $250 on an average service call. Your break-even is under one job. One saved call a month and you're square; the second one is profit. If you clear $80 on a typical job, break-even is closer to three calls a month — still low, but you should want more evidence before signing.

The reason this framing beats staring at the price tag is that it puts the cost next to the thing it's buying. $200 a month sounds like a real expense. "One job" sounds like a Tuesday.

Now the harder half: how many calls are you actually missing?

Break-even only tells you the bar. Whether you clear it depends on how many calls currently go unanswered — and most owners genuinely don't know, because a missed call leaves no trace beyond a line in a call log you don't review.

Spend a week counting. Your phone already has the data:

• Open your recent calls and count inbound calls you didn't answer. Include the ones you called back — they still went unanswered at the moment the customer needed you.
• Separate the numbers you recognise from the ones you don't. A missed call from an existing customer usually survives. A missed call from an unknown number is a stranger who was choosing between you and the next result.
• Note the ones that came outside working hours, and the ones that landed while you were on another call. Those are the two categories you're structurally unable to fix by trying harder.

A week of this is usually enough to settle the question. If you're missing eight unknown-number calls a week and your break-even is one job a month, the arithmetic isn't close. If you're missing one call a fortnight, be honest with yourself and skip it — you don't have a phone problem.

The number people get wrong: the value of a saved job

Most owners run this math using the profit on a single job, which understates it — often badly. A first-time caller who becomes a repeat customer is worth the first job plus everything after it: the annual service, the callout in three winters' time, the two neighbours they mention you to.

That doesn't mean inventing a big number to justify a purchase. It means recognising that using single-job profit gives you a *conservative* break-even. If the decision already works on the conservative version, it works. We went through what a new customer is really worth separately, and the gap between the two figures is usually the whole argument.

What can make it not worth it

Being straight about this, because the honest cases exist:

1. 1You barely miss calls. If you're office-based with someone on the phone all day, you're buying a solution to a problem you don't have.
2. 2The pricing model punishes your good months. Per-minute and per-call plans mean your bill spikes in exactly the month the storm hits and the phone won't stop. That's when cost becomes unpredictable — the mechanics are in how much an answering service costs.
3. 3It only takes messages. A service that hands you a list of people to ring back hasn't saved the job — it's moved the callback from your voicemail to their notepad. The customer still waited. You still have to chase.
4. 4Your callers need real answers. If a caller asks whether you cover their suburb and the answer is "someone will get back to you", you've paid for a slower voicemail.

That third point is the one that decides most of these. A booked job is worth the fee. A message is worth a fraction of it, because the caller has usually moved on by the time you ring back.

The question to finish on

Not "can I afford this" — but "what's it costing me to keep doing what I'm doing?" Missed calls don't appear on a bill, which is exactly why they're easy to keep paying for. The service has a price you'll see every month. The missed calls have a price you'll never see at all.

June is a flat monthly fee, so your bill doesn't move when your call volume does — the busy month that would spike a per-minute plan costs the same as the quiet one. She answers your line 24/7 in your business's name, takes the caller's details, and books the job.
