# Custom AI voice bot development: how we build a bot that sells

How we build a done-for-you AI voice bot: a lead target, a sales funnel review, offers, a call strategy, AI training and rounds of 100 calls until it pays off.

Section: Getting started · Updated: 2026-11-10 · http://my.lptracker.ru/land/lk/faq/?a=voice-bot-turnkey&lang=en

> **In short:** Custom AI voice bot development is a done-for-you service: our implementation team builds the bot around your business goal — from a sales funnel review and offers to training on your materials and rounds of 100 test calls until the bot brings the number of leads you need. Before you order, call our demo bot at +7 (988) 197-37-66 and try to break it.

Custom AI voice bot development is not about a bot that sounds nice: almost everyone has a pleasant synthetic voice today. If you want an AI voice bot built for your company, it has to find the answer in your knowledge base in about a second and a half, talk to clients like an experienced head of sales, and bring in leads, meetings and sales. That is the bot we build — around the goal, niche and sales funnel of each client.

> Choosing who should build your AI voice bot? Before you pay anyone, call an AI voice bot and test it — that is the only way to hear the real quality. Our demo bot answers at **+7 (988) 197‑37‑66**. Try to break it: interrupt, object, ask awkward questions, go off topic. Five minutes of a call like that tell you more than any presentation.

## A voice bot that “sounds nice” vs a voice bot that sells

You don't hear the difference in the first sentence, but in the third minute of the call — when the client asks about the price, has doubts or goes off topic.

| What matters | A bot that “sounds nice” | A custom AI voice bot |
| --- | --- | --- |
| Answers | Generic template phrases | Facts, prices and terms from your knowledge base |
| Objections | “OK, I'll pass this on to a manager” | Finds out what holds the client back and answers like a head of sales |
| Call goal | Just to talk | A lead, a meeting or a booking for an exact time |
| CRM | A call recording, and that's it | A funnel step, card fields and a call summary |
| Result | “Sounds pretty good” | Leads according to the target set at the start |

## Stages of custom AI voice bot development

We don't start with a prompt. First comes the goal and the money, then the messaging and the strategy, and only then the bot itself.

1. **A target in numbers** — We agree on the result the bot must reach: for example, 400 leads a month.
2. **Sales funnel review** — We find the bottlenecks the voice bot will fix.
3. **Offers and messaging** — Together with the owner we dig out your advantages and package them into offers.
4. **Call strategy** — We choose the reason for the call, the call goal and the stages that lead to it.
5. **Knowledge base and data** — Prices, terms, answers to objections, schedules and the CRM in real time.
6. **AI training by the checklist** — We play out dialogues as a client and fix the replies, funnel steps and CRM fields.
7. **Rounds of 100 calls** — We listen to the recordings, measure conversion, fix and launch again until we hit the target.

## Stage 1. The goal: how many leads the bot should bring

The work starts with a number, not with a voice. Together with the client we set the goal the bot must reach — for example, 400 leads a month. From the goal we count backwards: how many conversations, calls and phone numbers you need and what one lead will cost. That way you know before launch whether the goal is realistic for your contact base. It's the same logic as in a [sales target breakdown](http://my.lptracker.ru/land/lk/faq/?a=analytics-decomposition&format=md&lang=en).

| Metric | Example | Where it comes from |
| --- | --- | --- |
| Goal | 400 leads a month | Set together with the owner |
| Conversation-to-lead conversion | 5% | A hypothesis — tested on the first 100 calls |
| Conversations needed | 8,000 a month | 400 ÷ 5% |
| Answer rate | 40% | Depends on the base and the time of the call |
| Calls needed | 20,000 a month, about 1,000 per working day | 8,000 ÷ 40% |
| Spend on minutes | about $1,440, roughly $3.60 per lead | 8,000 conversations ×  1.5 minutes × $0.12 |

The numbers in the table are an example for the calculation: the real conversion and answer rate come from the first rounds of calls. A minute of the bot's conversation costs $0.12 on average, and speed doesn't limit the plan — the bot makes up to 200 calls a minute.

## Stage 2. Funnel review: which bottlenecks the bot will fix

Next we review your current sales funnel: where leads come from, how soon they get a call back, where clients drop off and what your managers waste time on. A voice bot doesn't replace your sales team — it's a precise fix for specific bottlenecks. Most often these are:

- **Slow first contact.** A lead gets a call back hours later, and the client is already with a competitor. The bot calls within the first minute.
- **Missed calls** at peak times, at night and on weekends. The bot answers every call at once, 24/7.
- **A dead contact base.** Thousands of contacts who once left a request and disappeared. The bot calls them with a new reason.
- **Empty leads for managers** — “just looking”, duplicates, wrong targets. The bot qualifies them and passes on only the warm ones.
- **Giving up at the first “I'll think about it”.** The bot finds out the reason for the doubt and answers it.
- **No-shows.** The bot reminds the client about the meeting the day before and confirms it.

> The bottleneck was first contact. Brokers spent the whole day at viewings and called leads back after 2.5 hours on average. The bot calls back within a minute, clarifies the property, area, budget and payment method and passes a warm lead to the broker with a call summary. Time to first contact is 60 seconds instead of 2.5 hours, and the bot filters out every third lead before it reaches a broker. Launched in 6 days.

## Stage 3. Offers and marketing messaging

A bot sells exactly as well as your offer does. So together with the owner we dig out every advantage of the business and package it into messaging and offers — short proposals that keep the client on the line past the first ten seconds. What we find out:

- what clients really pay for and what holds them back;
- proof: numbers, timelines, guarantees, reviews, well-known clients;
- reasons to call: a promotion, new stock, a free site survey, a trial lesson;
- answers to objections that your best salespeople use.

> One strong offer in the first sentence works better than ten advantages in the middle of the call. The client decides whether to keep listening within the first few seconds.

> Users signed up and disappeared, and managers could only call some of them. We packaged the product's value into a short pitch tailored to the client's role — site manager, crew or company — plus answers to “too expensive”, “I use Excel” and “no time to figure it out”. The bot calls on the day of sign-up, pitches the product in two minutes and books a demo. Now 19% of sign-ups reach a demo instead of 7%.

## Stage 4. Call strategy: the call goal and stages

Coming up with an offer is not enough — it has to land. So we develop a call strategy: for calling your contact base or for inbound calls that need to be handled well and turned into leads. For outbound calls we brainstorm several strategies: who to call, with what reason, at what time and what to say in the first sentence. Then we choose the call goal — a lead, a meeting, a booking or a transfer to a manager — and the stages that lead to it:

1. A greeting and the reason for the call — the offer in the first sentence.
2. Needs discovery — two to four questions your best salesperson would ask.
3. An offer based on the client's answer.
4. Objection handling.
5. The target action: a booking, a meeting, a lead or a call transfer to a manager.
6. The summary in the CRM: a funnel step and card fields.

All of this goes into the bot's conversation plan. The owner approves it: we don't start the calls until you have read the plan and agreed with it. How the instruction and the plan work is covered in the article “[AI voice bot script](http://my.lptracker.ru/land/lk/faq/?a=voice-bot-prompt&format=md&lang=en)”.

> There were plenty of leads, but only one in five reached a viewing — managers gave up after the first “I'll think about it”. The bot's strategy: find out what holds the client back, answer the doubt with facts from the knowledge base — properties, mortgage, installments — and right away offer a specific viewing time from the broker's schedule. Now 34% of leads reach a viewing instead of 18%.

## Stage 5. Knowledge base and real-time data

The hardest part of a voice bot is accuracy, not the voice. The bot keeps the whole conversation and large databases in memory, so it doesn't forget what the client said at the start. And through dynamic webhooks it asks your system for free slots, addresses, staff and stock during the call — and books the client for an exact time without mixing up dates or addresses. Connecting this data is exactly the part that pays to leave to the implementation team. More in the article “[AI voice bot knowledge base](http://my.lptracker.ru/land/lk/faq/?a=voice-bot-knowledge&format=md&lang=en)”.

> Almost all orders come in the morning, and two operators couldn't keep up — every fifth call went unanswered. The bot answers all calls at once, recognizes a regular client by phone number, offers to repeat the last order and clarifies the address, delivery window and payment. Missed morning calls dropped to 2% from 22%, and calls to clients whose water is due to run out brought +18% repeat orders.

## Stage 6. AI training: the bot readiness checklist

Here the road forks. If you have a proven script or call recordings that definitely converted, we transfer them into the bot: the AI learns from what already works. If there is no such script — and most companies don't have one — we don't automate guesswork, we train the AI bot: we play out dozens of dialogues as your clients and fix the replies until the bot answers the way your head of sales would. We go through every item of the readiness checklist, which the dashboard shows after you save the bot, together with you:

| Checklist item | What we do | What it gives your business |
| --- | --- | --- |
| Training on your own materials | We load everything your salespeople know: services, prices, terms, answers to every question | The bot answers with your company's facts, not generic words |
| AI training (bot replies) | We chat with the bot as a client, find a weak reply, press “Fix” and describe how not to answer and how to answer | We break the bot before a client tries to |
| Conversation plan | The owner reads the plan and makes edits | The bot runs the call by the agreed strategy |
| Funnel stages training | We play out dialogues and teach the bot to set the right funnel step in the CRM in every situation | You can trust your analytics: “Interest” really means interest |
| Writing to CRM: field “…” | We check every new field — budget, area, date — when there was no conversation and when it reached the goal | A manager opens the card and sees the full picture at once |
| Link an inbound number | We link a number to the bot and call it ourselves | We test everything in a live call, not on paper |
| AI training on real calls | After the first calls, the AI reads every conversation in full and fixes the instruction based on the mistakes it finds | The bot learns from real people, not from guesses |

> You can't just tick a box. “AI training” counts only after a reply has been fixed, and “Link an inbound number” only once a number is linked. That way the bot doesn't start calling half-trained, and your call budget doesn't go to waste.

> More than half of the consultations were off-target — the debt was too small or property was at risk. The bot asks the same questions a lawyer asks at the first consultation: total debt, creditors, income, property, mortgage. The answers go into CRM card fields, so the lawyer sees the situation before the meeting. The share of on-target consultations grew from 30% to 72%.

## Stage 7. 100 test calls, a review and another 100

After training we launch the first 100 calls. We listen to the recordings, look at the conversion to a lead and the cost per lead, and find the question where clients hang up and where the bot loses the conversation. We fix the instruction, the offer or the strategy — and launch the next 100. We repeat the rounds until the bot reaches the goal set at the first stage.

1. **100 calls** — To your base or on inbound calls.
2. **Listening** — Recordings and transcripts of every conversation.
3. **Numbers** — Conversion and cost per lead; where the bot loses clients shows up in “[AI conversion analysis](http://my.lptracker.ru/land/lk/faq/?a=ai-conversion-analysis&format=md&lang=en)”.
4. **Fixes** — The instruction, the offer, the strategy and the replies.
5. **Another 100 calls** — And so on until we hit the target.

> Ten calls don't show any patterns, and a thousand calls on a raw script will burn your base. A hundred is enough to see the conversion, and it's no loss if a hypothesis doesn't work. How to run training rounds is covered in detail in the article “[How to train an AI voice bot](http://my.lptracker.ru/land/lk/faq/?a=voice-bot-training&format=md&lang=en)”.

For inbound calls we switch calls to the bot in portions: first the ones operators miss, then on a schedule, and once the bot covers about 95% of situations — all calls. Timelines by scenario: calling back website leads takes a couple of days, calling people who left a request and disappeared usually takes 5–10 days, and training for inbound calls takes a couple of days, no more than seven.

> Only one lead in seven reached a site survey — the first call was spent on general questions. After the rounds of calls, the bot finds out the plot, floor area, material, budget and timeline in the very first call and books a site survey right away. Now 33% of leads reach a survey instead of 15%, and the time from request to a site visit is two days shorter.
