Is 24/7 IT Support Really Worth It? An Evaluation Guide for SMEs

IT system failures outside of business hours are a critical vulnerability for many SMEs. This could be an e-commerce website unable to process orders at night, a hotel's room booking system going down during a long holiday, or a critical application failing when urgently needed.

The consequences are a rapid loss of business opportunities, revenue, and customer trust. For this reason, many organizations are beginning to consider whether investing in 24/7 IT Support is truly worthwhile.

This article will analyze the pros and cons, the true costs, and present a systematic approach to evaluating its value, helping SME executives make informed decisions.

Understanding 24/7 IT Support 

• 24/7 IT Support refers to services that manage computer systems and information technology around the clock, 7 days a week. Whether it's a holiday or outside business hours, the IT team monitors, troubleshoots, and ensures systems operate continuously.

Comparing Different Types of IT Support

Standard IT Support (Business Hours)

• Operates only Monday-Friday, 9:00 AM - 6:00 PM. Suitable for businesses with no operations outside these hours. Lower cost, starting from approximately 10,000-30,000 Baht/month. If a problem occurs outside hours, resolution must wait until the next business day.

24/7 IT Support

• Operates around the clock, including holidays and nights. Features a team for real-time monitoring and troubleshooting. Ideal for businesses with online sales or continuous services. Can respond to and resolve issues immediately, regardless of the time.

Benefits of 24/7 IT Support for SMEs

1. Reduce Downtime and Revenue Loss

When systems fail, every minute that passes means lost money. Having a 24/7 IT Support team enables immediate problem resolution, regardless of the time. There's no need to wait until the next business morning, reducing system downtime from several hours to just 10-15 minutes. This prevents revenue loss from inactive sales systems and maintains business continuity.

2. Boost Customer Confidence

In the digital age, customers expect constant service availability. 24/7 IT Support ensures your customers can use your services at any time without worrying about system issues. This builds a professional and trustworthy image, reduces the chance of customers switching to competitors when problems arise, and increases customer satisfaction and loyalty.

3. Proactive Monitoring

Effective 24/7 IT Support doesn't just wait for problems to occur; it includes monitoring systems that detect anomalies before they escalate into major issues, such as near-full storage space or abnormal CPU load. It analyzes trends and provides advance warnings, performs system updates and maintenance during off-peak hours to avoid disrupting operations, and regularly backs up data and checks security.

4. Support Business Growth

As businesses expand, IT systems become more complex and critical. 24/7 Support helps accommodate branch expansion or teams working in different time zones, supports international sales or 24-hour online markets, assures businesses that their systems are constantly monitored, and facilitates remote or hybrid work where employees may be in different time zones.

Considerations and Costs
True Costs

24/7 IT Support incurs higher costs than standard support due to the need for rotating teams to provide continuous coverage. Generally, it can be categorized into three main models:

• In-house (Hiring your own team) Salary costs for 3-4 shifts (8-12 people) approximately 150,000-250,000 Baht/month, plus equipment and software costs for monitoring systems and training expenses. Suitable for large organizations with complex IT systems and sufficient budgets.
• Outsource (Hiring an external company) Service fees start from 20,000-80,000 Baht/month, depending on business size and system complexity. More cost-effective than hiring an in-house team, offers flexibility in scaling services, and provides access to experienced specialists. Ideal for SMEs seeking value and expertise.
• Hybrid Support Full-time support during business hours, plus on-call service for emergencies outside hours. Costs 15,000-50,000 Baht/month. Suitable for businesses that don't frequently experience off-hours problems and can upgrade to full 24/7 as the business grows.

Which Businesses Should Consider It?

Businesses that should have 24/7 IT Support

• E-commerce businesses with customers making purchases 24 hours a day.
• Service businesses like Logistics, Hospitals, Hotels that provide continuous services.
• Fintech or financial businesses requiring high security and continuity.
• Businesses where system downtime severely impacts revenue.
• Businesses selling internationally or with customers in different time zones.

Businesses where it may not yet be necessary

• Businesses that operate only during normal business hours and have no online channels.
• Businesses where off-hours system downtime does not directly impact revenue.
• Businesses with a small customer base and limited budget.
• Businesses that can afford to wait until the next business morning for problem resolution.

5-Step Decision-Making Guide

Step 1: Assess the Cost of Downtime. Calculate how much revenue you would lose if your system went down for 1 hour outside business hours, including the impact on customers and reputation.

Step 2: Review Problem History. How often do your systems go down outside business hours? What recurring problems do you experience?

Step 3: Compare Costs. Multiply your Cost of Downtime by the frequency of incidents and compare it to the cost of 24/7 IT Support.

Step 4: Consider Growth Plans. What direction is your business expanding in? Will you be entering international markets or expanding online channels?

Step 5: Start with Hybrid if Unsure. If you're still uncertain, consider starting with Hybrid Support and then upgrading to 24/7 as your business grows and the need becomes clear.

How Ready Is Your Business for System Downtime?

Assessing the Cost of Downtime is a crucial tool to determine if 24/7 IT Support is worthwhile. If your calculations reveal:

• Cost of Downtime > Cost of 24/7 IT Support → You should invest.
• Cost of Downtime < Cost of 24/7 IT Support → Consider Hybrid or Business Hours Support.

The key is: don't wait for a major problem to occur. Evaluate your business today and prepare for the future.

The decision should be based on actual business data, not trends. Try evaluating by looking at your Cost of Downtime, problem frequency, and future growth plans. If still unsure, starting with a Hybrid Support package and then upgrading to 24/7 as your business grows and is ready is a smart choice.
