For most solo tradies and small crews doing fewer than 15 after-hours calls a week, an AI receptionist is the better value. It typically costs $50 to $200 a month with no per-call fees, answers every call instantly day or night, and books the job straight into your job app. A human answering service suits businesses handling complex or sensitive enquiries where a real voice adds trust, but the per-call model ($2 to $6 per call plus a monthly retainer of $50 to $150) gets expensive fast as volume grows. The deciding question is your breakeven: how many calls a week does each option need to capture to pay for itself at your average job value?
Key takeaways
- A human answering service typically costs $2 to $6 per call plus a monthly retainer, while an AI receptionist runs $50 to $200 a month flat with no per-call charge.
- At 10 after-hours calls a week and an average job value of $800, AI breaks even by capturing just one extra job a month, while a human service needs higher capture to cover its rising per-call cost.
- Speed to lead matters: responding within one minute lifts conversion by up to 391 percent compared to a delayed callback, and AI answers instantly every time.
- The right choice depends on call volume, job complexity and budget. Many tradies start with AI for always-on coverage and add people later as they scale.

How much does an after-hours answering service actually cost?

A human answering service in Australia typically charges in two parts: a monthly retainer of $50 to $150, plus a per-call fee of $2 to $6 depending on call length and complexity. Some services add surcharges for after-hours, weekend or public holiday calls.
An AI receptionist runs differently. Most providers charge a flat monthly fee of $50 to $200 with no per-call charge, so the cost stays the same whether you get five calls a week or fifty.
| Cost component | Human answering service | AI receptionist |
|---|---|---|
| Monthly retainer | $50 to $150 | $50 to $200 (flat, all-inclusive) |
| Per-call fee | $2 to $6 | None |
| After-hours surcharge | Often yes | No |
| Cost scaling | Rises with every call | Flat regardless of volume |
The pattern is clear: a human service gets more expensive as call volume rises, while AI stays flat. At 10 after-hours calls a week, a human service runs roughly $130 to $390 a month once per-call fees are added to the retainer, while AI stays at its flat rate. At 30 calls a week the human service climbs to $290 to $870 a month. For a tradie fielding regular after-hours calls, the cost difference is substantial over a year.
What is the breakeven point for each option?
Most tradies break even on an AI receptionist by capturing just one extra job a month, while a human service needs a higher capture rate to cover its rising per-call cost.
- Work out your average job value. For most residential trades, this sits between $300 and $2,000. Use your own number from the last quarter, not an industry average.
- Estimate your after-hours call volume. Check your phone's missed-call log for the past month. Many tradies are surprised to find 20 to 40 percent of their inbound calls land outside business hours.
- Calculate the monthly cost of each option. Use the table above with your actual call volume.
- Divide the monthly cost by your average job value. That is how many extra jobs per month the service needs to land to break even.
At an average job value of $800 (a common mid-range for residential electrical, plumbing or HVAC work) and 10 after-hours calls a week, an AI receptionist at $150 a month breaks even by capturing just one extra job every five to six weeks. A human service at $300 a month needs one extra job roughly every two to three weeks.
Does speed to lead actually matter for tradies?

Yes, and the data is striking. Lead-response research compiled by Casey Response (drawing on earlier Velocify data) found that responding within one minute lifts conversion by up to 391 percent compared to waiting even a few minutes. Separately, roughly 78 percent of customers buy from the first business to respond.
For tradies, the implication is direct. A customer with a blocked drain at 7pm on a Tuesday is not going to wait until you check your voicemail at 9pm. They will call the next plumber on Google. Around 95 percent of home services businesses do not respond within five minutes, according to a Convoso industry study. That means simply answering fast puts you ahead of almost every competitor.
- AI answers instantly. Every call, every time, no hold music, no voicemail. It qualifies the job, captures the details, and texts you a summary.
- A human service answers within a few rings. Good, but often reads a generic script and emails you a message rather than booking the job directly.
- Voicemail loses most callers. Most people hang up rather than leave a message, especially for urgent jobs. See our breakdown of missed call costs for tradies. For a head-to-head feature comparison, read after-hours answering service vs AI for tradies.
When does a human answering service make more sense?
AI is not the right fit for every business. A human answering service can be the better choice in specific situations.
- Complex or sensitive enquiries. If your business handles insurance work, strata management or body corporate calls where the caller needs reassurance and nuance, a trained human operator handles those conversations better than current AI.
- High-value commercial contracts. When a single job is worth $10,000 or more, the cost of a human answering the phone is trivial relative to the contract value, and the personal touch can make the difference.
- Customers who prefer a person. Some demographics and industries still prefer speaking to a real person. If your customer base skews older or your work involves sensitive situations, factor that in.
The honest answer is that many growing trade businesses end up using both: AI for always-on coverage and fast qualification, with a human layer for complex jobs. For a practical look at how each option handles bookings, see our guide on getting an AI receptionist to take bookings.
How do I work out which option suits my business?

Start with your own numbers, not an industry benchmark. The comparison below uses a simple framework any tradie can run in ten minutes.
| Decision factor | Leans toward AI | Leans toward human service |
|---|---|---|
| Call volume | 10+ calls/week (flat cost scales well) | Under 5 calls/week (per-call cost stays low) |
| Job complexity | Standard residential (quote, book, confirm) | Complex commercial or insurance work |
| Budget | Tight, needs predictable monthly cost | Flexible, willing to pay for premium feel |
| Integration | Wants bookings straight into ServiceM8, Tradify or simPRO | Happy with an email summary to follow up later |
| Hours needed | True 24/7 including weekends and holidays | Business hours overflow or limited after-hours window |

Any automation we build, whether AI receptionist, text-back or follow-up, is consent-first and honours STOP and opt-out under the Spam Act 2003.
As the ACCC states: If you're in business, you must not mislead or deceive consumers. This includes making false or misleading claims about the nature, characteristics or suitability of goods or services.
We apply that standard to our own recommendations: every cost range above is a directional benchmark from published provider pricing and industry sources, not a guarantee for your business. Your actual costs depend on your provider, plan and call volume.

Common questions
How much does an after-hours answering service cost in Australia?
Most charge a monthly retainer of $50 to $150 plus a per-call fee of $2 to $6 depending on call length and complexity. After-hours and weekend calls often carry a surcharge. Total cost depends on your call volume.
Is an AI receptionist cheaper than a human answering service?
Usually yes, especially as call volume grows. AI typically charges a flat $50 to $200 a month with no per-call fee, while a human service costs more with every additional call. At 10 or more calls a week, AI is materially cheaper.
Can an AI receptionist book jobs into my job management app?
Yes. Many AI receptionists built for tradies can integrate with job management apps like ServiceM8, Tradify or simPRO. The AI answers, qualifies the job, captures the details and books it straight into your system without you touching the phone.
Should I use both an answering service and AI?
Many growing trade businesses do. AI handles always-on coverage and fast qualification for standard jobs, while a human layer handles complex or sensitive enquiries where a real voice adds trust. The right mix depends on your job types and call volume.
How many extra jobs does an answering service need to capture to pay for itself?
Divide the monthly cost by your average job value. At $150 a month and an $800 average job, the service pays for itself by capturing just one extra job every five to six weeks. Use our missed call cost calculator to size the gap for your business.
