Temperature records kept by hand or in Excel tend to delay the detection of anomalies and provide weak evidence during audits. As Thailand’s economy heads toward 2026, slowing growth is increasingly on people’s minds, and across manufacturing, logistics, and consumer-facing operations, costs and administrative burdens that cannot be absorbed simply by growing sales are mounting. At the same time, BOI is encouraging investment related to automation, AI, data analytics, enterprise management IT, and Industry 4.0. As a result, situations where investment should be halted and situations where it should instead be advanced now coexist.
Temperature control is not merely a record-keeping task; it is a mechanism for detecting quality risks early and demonstrating reassurance to customers. What matters is not DX as a buzzword, but DX that connects to on-site numbers and management decisions. The challenge that TOMAS TECH must address for Japanese companies is not simply to introduce systems, but to standardize operations at Thai sites, reduce dependence on individuals, and create a return on investment that can be explained even to the Japanese head office.
1. Why this theme matters now
In Thailand in 2026, while overall economic growth slows, structural challenges remain—labor costs, energy, logistics, quality response, and a shortage of managers. In a strong economy, some waste can be absorbed by sales, but when growth is sluggish, small inefficiencies on the floor directly erode profit margins.
For this reason, investment decisions are no longer as simple as “advance because the economy is good” or “halt because the economy is bad.” What should be halted are large-scale investments with vague objectives. What should be advanced are investments that move concrete numbers—time saved, inventory discrepancies, defects, downtime, billing leakage, waste, and wait times.
2. Problems that commonly occur on site
Temperature records kept by hand or in Excel tend to delay the detection of anomalies and provide weak evidence during audits. What makes this problem troublesome is that it does not stay contained on the floor. If on-site records are delayed, the management department’s tabulation is delayed; if the management department’s numbers are delayed, management decisions are delayed as well. Furthermore, when explaining matters to the Japanese head office, problems occurring locally are hard to convey with a sense of urgency, making it harder to get investment approval.
At Thai sites, information in Japanese, Thai, and English is mixed together, and paper, Excel, existing systems, chat, and email tend to be fragmented. This very fragmentation is the first target for DX. Before expensive equipment or large-scale systems, the flow of information must first be put in order.
3. Points to consider in investment decisions
For this theme, there are three points to consider.
- Automatically capture the temperature of refrigerators and freezers
- Send alerts when deviations occur and keep a record of the response
- Automate reports for audits
These are not merely functional requirements. They are management requirements for explaining the return on investment. How many hours can be saved per month? Which mistakes are reduced? Which risks can be detected earlier? Can it be recouped within three years? Investments that can be explained in this way are worth advancing even when the economy is sluggish.
4. Implementation steps to start small
Step 1: Narrow the target to a single operation
If you aim for a company-wide rollout from the start, the requirements expand too far and the project stalls. First, narrow it to a scope where results are easy to see—one process, one warehouse, one store, one form, or one meeting.
Step 2: Do not increase the input burden on the floor
A major reason DX fails is that it increases the work on the floor. You need to choose input methods that feel natural to the site, using QR codes, barcodes, sensors, voice input, integration with existing Excel, and the like.
Step 3: Build it into meetings and KPIs
Data goes unused if there is no venue to review it. Build it into weekly meetings, morning huddles, quality meetings, sales meetings, and monthly reports, and decide who judges what.
Step 4: Record results in numbers
Record time saved, defect reduction, shorter wait times, reduced waste, reduced billing leakage, and the like. This becomes the material for the next investment proposal.
5. How to think about leveraging BOI and incentive programs
BOI places importance on investments that contribute to Thailand’s industrial upgrading, such as automation, robotics, AI, big data analytics, IT for enterprise management, and cloud adoption. Whether a specific case actually qualifies requires individual confirmation, but it is at least worth keeping BOI’s direction in mind in the early stages of an investment plan.
What matters is organizing the plan not as a mere equipment purchase or system introduction, but as an investment plan that encompasses productivity improvement, quality improvement, labor savings, data utilization, and sustainability. This is effective not only for BOI but also for explanations to the Japanese head office.
6. What TOMAS TECH can support
TOMAS TECH supports temperature-control IoT that combines sensors, the cloud, alerts, and reports. TOMAS TECH’s strength lies in being able to consider, as a single flow, the on-the-ground reality of Japanese companies in Thailand, explanations to the Japanese head office, system implementation, AI utilization, and accounting DX.
Simply building requests as-is, like contract development, can end up merely transferring the complexity of the floor into the system. What is needed from here is support premised on standardization, non-customization, phased introduction, and operational entrenchment. Build small, use it on the floor, measure the results, and then expand to the next area. This approach is the most realistic for Thai sites.
Summary
The theme “Graduating from Excel for Temperature Control: IoT Refrigeration and Freezer Management for Thailand’s Food Industry” is not merely a story about introducing IT. Amid an environment of slowing growth, rising costs, talent shortages, and heightened quality demands, it is a management theme about how Thai sites can protect their profit margins and on-the-ground capabilities.
What is needed in 2026 is not flashy DX, but DX that changes the numbers on the floor. Separating investments that should be halted from those that should be advanced, and accumulating small improvements that can be framed around a three-year payback, becomes the most solid growth strategy for Japanese companies in Thailand.
