How many contacts a month make a voice agent worth it?

If your business gets fewer than 30 to 40 contact requests a month, a voice agent is probably not the first step. Above that volume, it is worth at least testing one, especially if you lose calls out of hours or your team cannot answer everything. It is the rule we use at Nauva before proposing anything, and we have already told businesses "no" when they did not need it.

Why volume is the first question

A voice agent solves a problem of scale: many calls, few people, opening hours that do not cover everything. With few contacts the problem does not exist, and the setup and testing effort does not pay off. Nobody needs a sledgehammer to crack a nut.

So before talking about technology, we start by counting.

How to count your contacts

Count every contact request over four weeks, not just the calls you answered:

• answered and missed calls (your phone provider or switchboard log shows both);
• calls outside working hours and at weekends;
• website form messages, and emails asking for information or a quote;
• social media and WhatsApp messages that are real requests.

If your business is already on Google, your profile also shows how many people called from search.

The maths, step by step

You need four numbers:

1. C, the contacts per month;
2. P, the percentage that goes unanswered (missed, out of hours, no follow-up);
3. Q, the share of those contacts that would become customers;
4. V, the average value of a new customer.

The value you are letting slip each month is roughly C × P × Q × V.

Illustrative example (your numbers will differ): 60 contacts a month, 25% unanswered, 1 in 3 would become a customer, each customer is worth €150. That is 60 × 0.25 × 0.33 × 150, about €750 a month.

Compare that with the cost of a solution: on the Nauva platform, the voice agent starts at €39 + VAT per month, with 100 minutes included, and there is no lock-in. The calculation does not guarantee how much you would recover, it shows what is at stake. If the result is a few tens of euros, a voice agent is not the priority.

Below 30 to 40 contacts: what to do instead

At this volume, it is better to solve the problem with something simpler:

• Automatic email reply drafts. It is one of the quickest wins: every request gets a ready answer to review and send.
• Online booking, so customers do not need to call.
• Website chat answering the frequent questions.
• An automatic message to anyone who calls and is not answered, with the booking link or your opening hours.

Count again in three months. If the volume has grown, the maths changes.

Above that volume: when it really pays off

It is worth testing when one more of these signs shows up:

• Calls out of hours or at weekends. At a cleaning company we followed, about 30% of calls arrived outside working hours, and the owner did not even know.
• The team always answering the same questions. One of our customers estimated he spent 60% to 70% of his phone time giving the same answers. It is his own estimate, but it is a common pattern.
• Call peaks when nobody can pick up.
• Follow-up that fails. The customer calls, nobody answers, nobody calls back.

The goal is not to replace the people who answer. It is to take the repetitive work off them, so they have time for the customers who need real attention.

Volume is not the only question

There are cases where few calls justify a voice agent, because each one is worth a lot or cannot be missed, for example emergencies and breakdowns out of hours. And there are cases where the volume is high and it is not worth it, because the software the business uses cannot connect the agent to the calendar. Volume is the first question, not the only one.
