Imagine this scenario: as a business leader, you decide to automate B2B cold calls. You tell your IT department to find a solution. After a few days, they return with a list: Retell AI, Bland AI, Vapi. Sounds great – the cost is just a few cents per minute, and the documentation looks modern.
You sign up. Your developers work for three months. And then the problems begin.
It turns out that the advertised $0.07 price was just the tip of the iceberg. Calls are lagging. Integration with your CRM system breaks every week. And worst of all, when the system calls a Lithuanian company director, it speaks with a strong American accent and cannot naturally pronounce the word “sąskaita-faktūra” (invoice). Your potential clients hang up within the first 5 seconds.
“Businesses don’t need API documentation. Businesses need generated meetings and qualified sales leads that automatically appear in your calendar.”
In this article, we will thoroughly examine the biggest market players (Retell AI, Bland AI, Vapi) and explain why they are designed for developers, not for business. We will also show why POSKAI is the only logical solution for Lithuanian and European companies looking for results as early as tomorrow.
What Exactly is an “API Platform” and Why Don't You Need It?
Retell, Bland, and Vapi position themselves as artificial intelligence voice platforms. But in reality, these are API tools for programmers (Developer APIs). What does this mean in business terms?
It means you're buying not a car, but only its engine. To drive it, you'll have to:
- Hire a team of developers to build a user interface (Dashboard).
- Program complex integrations with your CRM (HubSpot, Salesforce, Pipedrive).
- Develop your own analytics tools for call listening and performance evaluation.
- Address security vulnerabilities so that callers cannot manipulate the AI agent (“prompt injection” attacks).
- Manage server infrastructure and call traffic distribution.
You wanted to save money by optimizing sales, but instead, you became the developers of another piece of software. Your IT costs exploded, and sales results are still zero.
The True Cost of Retell AI: How $0.07 Turns into $0.18 Per Minute?
The price of Retell AI, which you see on the front page, looks incredibly low – just $0.07 per minute. However, after reading the fine print, the illusion fades. This price covers only the use of their infrastructure (engine).
For the system to actually work, you must connect and pay for three additional components yourself:
- Language model: You will need to connect your own AI model account. This will cost extra for every word generated.
- Voice generation: You will have to use a traditional text-to-speech system (e.g., from third-party providers), which adds another $0.03–$0.06 per minute.
- Telephony services: You will need a separate account for number rental and call routing, which costs at least another $0.02 per minute.
The final result? Your "cheap" call actually costs you $0.14 - $0.18 per minute. And what about the tens of thousands of euros you'll pay developers to connect and maintain these four different systems?
Bland AI Traps: You Pay Even When No One Answers
Bland AI applies an even more aggressive and business-unfriendly pricing model. First of all, their monthly subscription fee (which starts from a few hundred dollars) does not include any call minutes. This is just a fee to be able to use their API at all.
The second and most painful nuance in B2B sales – Bland AI charges you $0.015 for each call even if it's unsuccessful (unanswered, busy number, or rejected). If your database has 10,000 contacts, and 70% of them don't answer the first time (which is completely normal in cold calling), you're burning hundreds of dollars for complete silence.
Furthermore, Bland AI has no smart analytics tools for sales managers – it's just "bare" code whose data you will have to visualize yourself.
Vapi Complexity: Five-Component Pricing
Vapi probably offers the most complex pricing on the market. To calculate your costs, you'll need a mathematical education. Their final price consists of five variables:
- Basic Vapi fee ($0.05/min)
- Cost of your chosen Speech-to-Text engine
- Cost per token of your chosen AI model
- Cost of a traditional text-to-speech system
- Per-minute fee from your telephony provider
By our calculations, the real cost of using Vapi for businesses ranges between $0.23 and $0.33 per minute. At such a price, adding programming costs, hiring a traditional sales manager again starts to look like a wise investment.
The Language Barrier: Why Global Platforms "Break" in Lithuania
All these tools are developed in Silicon Valley, targeting the US market. They use outdated technologies (traditional text-to-speech systems), which sound quite good in English, but completely fall apart when faced with the Lithuanian language.
What will your customer hear if you try to adapt a US platform in Lithuania?
- The system will need at least 1-2 seconds to translate the customer's response into English, formulate a reply, and then translate it back into Lithuanian. This pause immediately reveals that a robot is speaking.
- Lithuanian place names (“Švenčionėliai”), surnames, and specific business terms (“PVM sąskaita-faktūra” - VAT invoice, “UAB” - Ltd.) will be pronounced with a broken, American accent.
- Mismatches in cases and conjugations will be commonplace.
In B2B sales, trust is everything. If your representative (even a digital one) sounds unprofessional, you lose the client within the first ten seconds.
| Platform | Platform Type | Lithuanian Language Quality | Real Cost | Developers Needed? |
|---|---|---|---|---|
| POSKAI | Business-Ready (All-in-one) | ✅ Ideal (Native AI) | From €500/month (all incl.) | ❌ Not Needed (Interface Ready) |
| Retell AI | API for Developers | ❌ Weak (Robotic, US accent) | $0.14 - $0.18/min + IT costs | ✅ Essential (Months of work) |
| Bland AI | API for Developers | ❌ Weak | $0.11 - $0.14/min (pays for fails too) | ✅ Essential |
| Vapi | API for Developers | ❌ Weak | $0.23 - $0.33/min + IT costs | ✅ Essential (Complex integration) |
POSKAI: The Complete Solution to Launch Tomorrow
We've seen companies waste tens of thousands of euros and months trying to build something functional from Retell or Vapi parts. That's why we created POSKAI – a platform built from the ground up specifically for B2B sales and customer service.
POSKAI is not a shell wrapped around third-party APIs. We do not use intermediary services from other companies. POSKAI is an independent platform that offers a completely different approach:
1. All-inclusive: No Surprises on Your Bills
With POSKAI, you don't pay for each individual component. Starting from €500 per month, you get everything: POSKAI AI, voice generation, telephony services, server infrastructure, and a detailed analytics panel. No hidden fees for unsuccessful calls. You know your budget precisely.
2. No Developers Needed
POSKAI is a ready-to-use platform (SaaS). You simply log into your account, upload an Excel contact list (or connect your CRM with a few clicks), define the POSKAI AI agent's goals, and click "Start Campaign." Your AI agent can make 500+ calls simultaneously. All you need to do is watch new warm leads appear in your calendar.
3. Flawless Lithuanian Language: No "Delays"
POSKAI uses our proprietary POSKAI direct audio technology. Unlike competitors who first convert audio to text, then process the text and convert it back to audio (which creates annoying pauses), POSKAI AI "hears" and "speaks" directly in audio. It understands intonations, interruptions, and speaks fluent Lithuanian – without any robotic accent, naturally reacting to customer responses within milliseconds.
4. Security and Infrastructure: European Standard
When you use US API platforms, your customer data travels through dozens of different third-party servers. POSKAI complies with the highest BDAR (GDPR) requirements – your data is secure and remains within the European Union. Every conversation is end-to-end encrypted. Furthermore, POSKAI AI has strict protection against so-called "prompt injection" attacks – no caller can manipulate your AI's behavior or extract confidential company information. US open-source solutions will not guarantee this.
Conclusion: What Should Your Company Choose?
The answer is very simple:
If you are a technology startup developing a new application and have a team of 5 developers with free time – use Retell or Vapi. These are excellent tools for building products from scratch.
But if you are a business owner, sales manager, or logistics company director who wants sales results without the headache and IT costs – POSKAI is the only logical solution. We don't hand you a box of parts. We hand you the best sales manager who never tires, speaks perfect Lithuanian, and is ready to work tomorrow.
