AI Voice Assistant ROI Calculator: How to Save Tens of Thousands of Euros

TL;DR: The average sales manager or customer service specialist in Lithuania costs a company about €2100–€3500/month (including all taxes). Meanwhile, a POSKAI AI voice assistant, processing 500+ calls per day, costs from €500/month. This creates immediate automation ROI and reduces routine communication costs by at least 4–7 times.

How Much Does a Single Calling Employee Really Cost?

In the Lithuanian B2B market, one fundamental mistake is often made — when calculating employee costs, only the "take-home" salary is considered. However, the true cost of an employee who sits on the phone all day (in sales, logistics, or customer service) is significantly higher. Managers who understand the numbers know that cold calls and answering repetitive questions are the most expensive time-consuming activities in a company.

If you want to calculate the real costs, you need to include the following factors:

  • Salary and Taxes: Even if you pay a modest €1200 "take-home" salary, this employee costs your company well over €2000/month (with all "Sodra" and GPM taxes). If it's an experienced SDR (Sales Development Representative), the price easily exceeds the €3000–€3500 mark.
  • Workplace and Equipment: Computer, professional headphones, ergonomic chair, office space rental, and utilities. This adds several hundred euros every month.
  • Software and Licenses: CRM system access, calling tools, email licenses.
  • Hidden Costs: Employees get sick, take 20 working days of vacation per year, go for coffee breaks, have "bad days" and burnout moments. In addition, employee turnover in call centers or entry-level sales is enormous. Searching for and training a new employee costs thousands of euros.

The result? You pay ~€2500 every month for a person who can physically make 30–50 quality calls per day. Out of those 50 calls, the majority end with answering machines, rejections, or phrases like "call back later." You are paying a professional's salary for a robot's job.

What is the ROI of the POSKAI AI Voice Assistant?

The return on investment (ROI) of artificial intelligence in business is calculated not in percentages, but in multiples. The POSKAI platform fundamentally changes the rules of mathematics in customer service and sales departments.

Let's take a real example from the logistics sector, where a dispatcher has to check statuses every morning and call dozens of drivers (read more about this in our logistics and transport use case). The dispatcher spends 2–3 hours of their valuable time on this. This is time when they could be looking for new cargo or optimizing routes.

The POSKAI AI assistant performs all these calls simultaneously in 5 minutes, collecting the necessary information and providing a clear list. Your employee only intervenes where a real problem arises (for example, a truck breakdown).

  • Employee Productivity: 30-50 calls in 8 hours.
  • POSKAI Productivity: 500+ calls simultaneously, 24 hours a day, 7 days a week.

“Artificial intelligence does not take away the work of your best salespeople. It takes over the part of the job that your best employees shouldn't be doing anyway — qualification, status checking, and routine questions.”

Per-Minute AI Pricing — The Biggest Market Trap

When companies start evaluating AI solutions, they often encounter foreign platforms that offer a "cheap" start — for example, €0.15 per minute. However, per-minute pricing is a hidden loss and a huge trap used by American platforms (such as Bland, Synthflow, or Retell).

Why does per-minute pricing destroy your ROI?

  • You pay for silence: When you call a client and they don't answer for 20 seconds — you pay. When hold music plays — you pay. When voicemail kicks in — you pay.
  • Hidden integration fees: Often, the base price does not include telephony charges or the cost of large language model queries.
  • Unpredictable budget: If your campaign is successful and the AI assistant makes 10,000 calls, at the end of the month you will receive a bill that will make you gasp — €2000 or even €5000.

The POSKAI approach is different. We provide a fully managed infrastructure. POSKAI pricing starts from €500/month. This is a fixed price with no hidden fees for minutes, telephony, or analytics. You know your monthly budget precisely and can generate maximum ROI without any risk.

Automation ROI by Use Cases

How does POSKAI pay off in different scenarios?

1. Cold Calling

An SDR (Sales Development Representative) makes initial contact and tries to engage the client. 90% of this time is spent on rejections. The POSKAI AI voice assistant can call a list of 1000 contacts in an hour and identify the 5% who actually want to talk. Your experienced (and expensive) salespeople then interact only with warm leads. You save not only SDR position costs but also drastically increase the "close rate" metric.

2. Debt and Payment Reminders

Payment delays directly impact a company's cash flow. Calling debtors is psychologically difficult for people, so they postpone it. The POSKAI assistant automatically, politely, and persistently reminds about unpaid invoices (more on this – payment reminders). Accelerated cash collection often recoups the annual cost of the POSKAI platform in just the first month.

3. Customer Service 24/7

If you have an e-shop, a hotel, or a clinic, customers want information around the clock. Hiring a person for a night shift just to answer the question "until what time are you open?" is financial suicide. POSKAI works without any additional charges for night shifts or holidays, automatically switches to the caller's language, and eliminates the problem of missed calls.

Conclusion: Why Waiting is Expensive?

Every month your expensive employees perform routine calls costs your business thousands of euros. AI voice technologies are no longer the future — they are the present. Companies that automate these processes today with POSKAI gain a drastic competitive advantage: they operate faster, their costs are lower, and customers get answers in seconds.
