The real cost of poor IT support: what every "small" outage actually costs you

Short answer: Poor IT support costs a company with 10 to 30 employees 15,000 to 35,000 EUR a year in lost productivity, outages and indirect costs. Most owners don't see this because there's no single line item for it it's spread across hundreds of micro incidents that nobody measures.

The most expensive IT support isn't the one you pay for. The most expensive IT support is the one you don't have, or have badly. Because its real bill gets paid in lost time, frustrated employees, missed deadlines, and every so often in one big disaster that changes the company forever.

In this article I break down every category of hidden cost with real figures for a company with 10 to 30 employees in Slovenia.

1. Lost time the quietest cost

The average office worker in Slovenia loses 2 to 4 hours a week to technical issues. A slow computer, a printer that doesn't work, a network outage, email problems, "I can't find this document", "Pantheon won't open". Individually: a few minutes. Cumulatively over a year: enormous.

Calculation for a company with 20 employees

• 20 employees × 3 hours a week = 60 lost hours per week
• Average hourly rate of an office worker in Slovenia 2026 (super gross, based on an average monthly salary of ~2,250 EUR): ~18 EUR/h
• Weekly cost: ~1,080 EUR
• Annual cost: ~52,000 EUR in lost productivity

Even if the real figure is half that (and with a well set up IT environment it is), we're still talking about 20,000 to 28,000 EUR a year going up in smoke. That's half of one employee's salary every year.

2. System outages a more visible cost, but rarely calculated

Small companies without professional IT support experience serious outages 1 to 3 times a month: email stops working, all computers slow down, the network drops, a key business application (Pantheon, Mit, ePoslovanje) crashes, a network drive becomes inaccessible.

Calculation for one hour of total outage

• Company with 10 employees: 10 × 18 EUR = 180 EUR / hour
• Company with 20 employees: 20 × 18 EUR = 360 EUR / hour
• Company with 30 employees: 30 × 18 EUR = 540 EUR / hour

And that's just the direct cost of lost work. It doesn't include: missed deadlines, an angry customer left waiting, a delayed supplier response, an unfiled tax return, unprocessed payroll. These are real consequences.

Real annual calculation

A typical company with 20 employees without proper IT support records:

• 2 serious outages a month × an average of 2 hours = 4 hours a month
• 4 hours × 360 EUR = 1,440 EUR a month in direct cost
• Annually: ~17,000 EUR

3. The "Slovenian IT model": calling for help with every incident

Many small companies pay an hourly rate of 50 to 80 EUR to an external technician who only shows up once the problem has already occurred. A typical scenario:

• The issue occurs on Wednesday at 10am
• You call the technician, who arrives Thursday afternoon
• ~10 working hours where 5 employees work at half capacity (5 × 18 × 10 × 0.5 = 450 EUR of loss)
• Plus missed deadlines and angry customers (hard to measure, but often just as large a cost in reality)
• The technician works 3 hours × 70 EUR = 210 EUR bill
• Direct price of one incident: ~660 EUR plus indirect consequences

From the technician's point of view, this is a small calculation (210 EUR). From the company's point of view, 90% of the cost is hidden in employees' lost time and never appears anywhere in the books.

The classic problem with the reactive model

Reactive IT (calling when something breaks) has three systemic problems:

• You pay for every problem twice: as an outage and as a repair
• The same issues keep recurring, because nobody addresses the root cause
• No documentation and no standards, every incident is treated as new

4. Security incidents infrequent, but devastating

Here the calculation shifts from "annoying" to "can destroy your company". EU 2025 statistics (ENISA) for small and medium companies:

• Average ransomware attack damage (Sophos State of Ransomware): 50,000 to 250,000 EUR
• Average BEC attack damage (CEO fraud, fake invoices): 40,000 to 120,000 EUR
• Average breach detection time (IBM Cost of a Data Breach): ~204 days
• Median total downtime after a ransomware attack (Coveware): ~22 days
• According to the Hiscox Cyber Readiness Report, almost half of small companies see revenue decline in the following year after a serious attack

Typical ransomware scenario for a Slovenian company with 20 employees

• Ransom (if paid): 20,000 to 80,000 EUR (doesn't guarantee recovery)
• Data and system recovery: 10,000 to 30,000 EUR for forensics and restoration
• Downtime: ~15 days × 8 hours × 360 EUR/h = ~43,000 EUR
• Legal costs (GDPR reporting, customer notifications): 5,000 to 15,000 EUR
• Reputation and lost customers: immeasurable

Total: ~80,000 to 170,000 EUR for a single event. Professional IT support with proper security (backups, EDR, updates, employee training) significantly reduces the likelihood of such an event not to zero, but from "likely" to "rare".

5. Employee frustration the long term tax

This is a cost you won't see in a spreadsheet, but you'll see it in staff turnover and the atmosphere in the company. An employee who works on a slow computer every day and spends 30 minutes a day complaining about IT:

• Is less productive (confirmed by research)
• Is more tired by the end of the day
• Is more likely to start thinking about changing jobs
• Doesn't suggest improvements, because "nothing's going to change anyway"

The cost of replacing one office employee in Slovenia in 2026 is 15,000 to 25,000 EUR (time spent recruiting, onboarding, lost productivity). If poor IT support contributes to losing one employee every 2 years, that's an additional 10,000 EUR a year in staff costs.

6. Lost customers and missed opportunities

The hardest cost to measure, but probably the largest. Concrete examples:

• An accounting firm misses the tax filing deadline because Pantheon crashes → loses a client + legal consequences
• A law firm can't access a document right before a court hearing → a very bad impression for the client
• A service company doesn't reply to a quote because Outlook is offline for 3 days → the client goes to a competitor
• E business with a key partner via SharePoint stops working → a contract at risk

Every serious incident can potentially cost a company 5,000 to 50,000 EUR in annual revenue through a lost client or missed opportunity. One a year is realistic.

Total annual calculation poor vs professional IT support

Realistically for a company with 20 employees:

Difference: ~33,000 EUR a year. This isn't a theoretical calculation these are real figures you're paying, they're just not on a single line item.

How to recognise you're paying the "hidden tax"

Typical signs that your current IT support is poor (or non existent):

• "Our IT person" is someone who does this alongside their regular job
• You pay an hourly rate for every single call, with no package
• The same problems keep recurring (one month, two, a year)
• You're not 100% sure whether your backups actually work
• Nobody knows who has access to what
• When the technician is on holiday, IT theoretically doesn't function
• Employees complain about their computers every day
• You have Microsoft 365, but only use Outlook
• No system documentation

If at least 3 apply, it's time for a review.

What "professional IT support" actually means

The definition isn't "someone who fixes a computer". Professional IT support means:

• Proactivity: problems are resolved before you notice them
• Predictability: a fixed monthly package, a defined response time
• Documentation: everything about your system is written down and accessible to you
• Security by standard: backups, MFA, EDR, updates
• One point of contact: one number, no being passed around
• Monthly report: what happened, what state your systems are in

The concrete next step

If you suspect you're paying any of the costs above, do one thing over the next 7 days, write down every IT incident that occurs in the company, and how long it took.

You'll probably be surprised when you see the number. A weekly total of 8 to 15 hours of lost time is perfectly normal for a small company and perfectly unnecessary.

If you need help reviewing your current IT situation, I'm available for a free 30 minute consultation. We'll look together at where you're losing time, and I'll be honest about whether it's worth investing in professional support, or whether things are already sorted well enough.
