Voice-Agent
for tradespeople:
do they pay off?

When does a voice agent really pay off?

"Voice agents are cool, but do they pay off for us?" — the most common question after a demo call. The honest answer: it depends on how many calls you miss or interrupt today. Not every business needs one. Here's a sober look at the numbers.

We take a typical trades business as a worked example — but the model works just as well for medical practices, law firms, restaurants and other service providers.

What a voice agent costs.

Let's take our Profi tier as a reference: €3,499 one-off, €349/month including 800 minutes. Calculated over 3 years:

One-off costs

• Setup & configuration: €3,499
• Conversation training (20 hours internal): approx. €600 opportunity cost
• One-off total: approx. €4,100

Ongoing costs (monthly)

• Profi retainer: €349
• Additional minutes (typically 200/month): €30
• Monthly total: approx. €330

3-year cost

€4,100 + (€330 × 36 months) = €15,980

That's the order of magnitude the voice agent has to justify.

What a voice agent saves.

This is where it gets interesting. A voice agent saves in three dimensions:

1. Staff time on the phone

Typical trades calls last 3 to 7 minutes. 70 to 90% of them are standard calls (appointment, price enquiry, address, standard question). The voice agent can take these over completely.

At 40 calls a day and avg. 5 minutes, that's 200 minutes of staff time a day. If the agent covers 75% of it automatically, you save 150 minutes — i.e. 2.5 hours a day.

2. Missed calls / lost leads

This is often the bigger item. When you're up on a customer's roof, every call goes unanswered. Industry studies show: 35 to 45% of callers in the trades don't call back, but dial the next number from Google.

At 40 calls a day that's 14 to 18 lost potential leads. If even 10% of them would turn into jobs (averaging €800), that's 1.1 to 1.4 missed jobs a day — in money: €880 to €1,120 of revenue a day that doesn't happen.

3. Night and weekend leads

A heating emergency on Sunday, an electrical emergency at 11pm, a burst pipe on Friday evening. If you're not reachable here, you lose premium jobs to the competitor with a 24/7 number. The voice agent always answers — and can prioritise and forward urgent cases.

Break-even by company size.

Three profiles from real projects (numbers anonymised, orders of magnitude authentic):

Small business: 3 staff, avg. 15 calls/day

• Staff-time saving: 60 minutes/day × €40/h × 220 days = €8,800/year
• Missed leads: 5 lost chances/day × 10% × €600 = €66,000/year (theoretical)
• 3-year saving (conservative, 30% of the theoretical value): approx. €42,000
• Voice-agent cost: €15,980
• ROI: 2.6x — clearly worth it

Medium business: 12 staff, avg. 40 calls/day

• Staff-time saving: 150 minutes/day × €40/h × 220 days = €22,000/year
• Missed leads: 14 lost chances/day × 10% × €800 = €246,400/year (theoretical)
• 3-year saving (conservative, 20% of the theoretical value): approx. €148,000
• Voice-agent cost: €15,980
• ROI: 9x — a clear win

Large business: 30+ staff, own switchboard

Here the calculation is more nuanced. If you already have a staffed switchboard, the voice agent mainly saves at night and on weekends — plus the switchboard can focus on complex enquiries. ROI is positive, but the business case is more about quality and 24/7 availability than about savings.

When a voice agent doesn't pay off.

There are clear situations in which we advise against a voice agent:

• Under 10 calls a day: staff handle that easily on the side. The one-off cost only pays off after years.
• Highly advice-intensive calls: if every call needs 20 minutes of individual consultation (e.g. a specialist for rare construction tasks), the voice agent only handles the easy cases — and that isn't the bottleneck.
• Businesses where every call is a job: if the conversion rate is 80%+ (e.g. a tax adviser with referral business), human interaction is the lever. Automation would be counterproductive.
• Very heterogeneous enquiries: if the business offers 15 completely different services and callers in each area want something different, bot training gets expensive and the result unreliable.

How to check it for your business.

Before you invest, do these three things:

1. Count your calls for 2 weeks: how many a day? How long on average? How many are standard, how many need expertise?
2. Estimate the missed ones: how often does the phone ring while you're on a job? How often is it busy? How many of them never call back? A realistic number is enough.
3. Plug numbers into the calculation above: your staff cost per hour, your average job value, your realistic conversion rate. Then you'll see whether a voice agent pays off for you or not.

We work through this calculation together in the first call — and tell you honestly if it doesn't pay off. It's happened more than once.

A voice agent is not an end in itself.

For medium-sized trades businesses (10+ calls/day, 5+ staff) the investment almost always pays off in the first year. For smaller or very advice-intensive businesses it doesn't. The question is never "is this cool" (yes, it is), but "does it pay off in my specific case" (usually yes, but not always).

If you're unsure: work it through with the table above. Or call us — we'll look at it together, with no intention to sell.
