The logistics industry is undergoing rapid digital transformation, with the Internet of Things (IoT) playing a central role. From real-time tracking and predictive maintenance to AI-driven route optimisation, IoT is revolutionising supply chain operations.
For logistics companies, the question is no longer whether to implement IoT technology, but how to maximise its impact. With supply chains becoming more complex, investment in digital solutions is accelerating. A recent McKinsey survey found that 87% of shippers have maintained or increased technology spending since 2020, and 93% plan to continue investing in the years ahead.
This article explores the most impactful applications of IoT in logistics, the business benefits, and the challenges that come with adoption—providing a roadmap for decision-makers looking to stay ahead in an increasingly competitive landscape.
IoT’s expanding role in logistics
For years, logistics was seen as a necessary cost centre—an unavoidable expense in getting products to market. That’s no longer the case. Today, supply chain efficiency is a competitive advantage, and IoT plays a key role in delivering faster, smarter, and more resilient logistics operations.
The market is growing fast. IoT in logistics is expected to exceed $63.7 (£49.3) billion by 2026, with a CAGR of 12.4%. The companies leading this shift aren’t just tracking shipments—they’re using IoT to build real-time, AI-driven decision-making systems that optimise fleets, prevent delays, and reduce costs.
This shift is particularly visible in three key areas:
- Visibility and tracking – IoT sensors provide continuous, real-time data on shipments, enabling better route planning, fewer delays, and improved risk mitigation.
- Automation and efficiency – AI-driven IoT solutions reduce manual intervention in warehouses, fleet management, and predictive maintenance, lowering costs and improving service levels.
- Resilience and risk management – Companies leveraging IoT can predict disruptions, optimise inventory, and react faster to geopolitical, economic, and environmental challenges.
The real-world applications of IoT in logistics
The real impact of IoT logistics solutions is seen in how companies are using it on the ground. Here’s how it’s transforming operations in shipment tracking, fleet management, warehouse automation, and cold chain logistics.
Shipment and fleet tracking
One of the most immediate benefits of IoT in logistics is the real-time tracking of assets, vehicles, and shipments. Traditional logistics models relied on periodic location updates along the journey, often leading to gaps in visibility and reactive problem-solving.
That approach is now obsolete. Today, IoT-connected GPS devices, RFID tags, and cloud-based tracking platforms provide continuous, real-time monitoring of shipments. This enables logistics teams to:
- Pinpoint exact locations of shipments at any given time
- Monitor temperature, humidity, and handling conditions for sensitive goods
- Automate alerts for delays, theft, or route deviations.
For example, DHL uses IoT-enabled SmartSensor technology to track real-time temperature, humidity, and location data for sensitive shipments. Additionally, GPS-enabled IoT devices and AI-powered data analysis to improve fleet efficiency and optimise last-mile delivery routes.
Predictive maintenance for vehicles and equipment
Unplanned equipment failures are a major cost driver in logistics, whether it’s a delivery vehicle breaking down mid-route or a warehouse sorting machine failing during peak hours. In the UK alone, LCV fleet downtime costs businesses an estimated £2.4 billion per year.
Traditional maintenance schedules—where vehicles are serviced at fixed intervals—lead to either unnecessary repairs or unexpected breakdowns that disrupt operations and increase costs.
IoT-powered predictive maintenance is changing that. By embedding sensors in trucks, forklifts, and warehouse machinery, companies can:
- Continuously monitor engine health, tyre pressure, and component wear
- Use AI-driven analytics to predict failures before they happen
- Reduce unplanned downtime and repair costs.
Royal Mail, for example, deployed predictive maintenance sensors on their carousel sorting machines, allowing them to detect early signs of motor failure before breakdowns occurred. This shift saved an estimated £50,000 per year in motor replacement costs, reducing both repair expenses and operational downtime.
Automated Inventory Management
IoT is transforming warehouse operations by using RFID tags, sensors, and real-time tracking systems to automate inventory management. Additionally, automated picking and sorting robots are streamlining order processing by reducing manual handling and improving efficiency.
This technology improves stock accuracy, reduces manual checks, and speeds up order fulfilment, helping businesses minimise errors and optimise storage.
Amazon’s fulfilment centres are a prime example of this transformation. By leveraging IoT, robotics, and AI, Amazon has cut fulfilment processing times by 25%.
IoT-enabled cold chain logistics
For industries such as pharmaceuticals, food, and chemicals, maintaining precise environmental conditions during transportation is critical. Temperature fluctuations, exposure to humidity, or mishandling can lead to product spoilage and financial losses.
IoT-powered cold chain monitoring ensures that temperature-sensitive goods remain within safe parameters by:
- Using real-time temperature and humidity sensors inside refrigerated trucks
- Automating alerts for deviations beyond acceptable thresholds
- Integrating blockchain verification to ensure tamper-proof, transparent tracking
Pfizer, for example, used IoT-powered cold chain logistics to safely transport COVID-19 vaccines worldwide. By ensuring precise temperature control, the company reduced spoilage and improved delivery success rates.
Business benefits of IoT in logistics
Beyond operational efficiencies, the adoption of IoT in logistics delivers tangible business benefits, including:
- Cost reduction – By optimising fleet routes, reducing equipment failures, and minimising waste, IoT lowers overall logistics expenses
- Improved customer satisfaction – Real-time shipment tracking and automated updates improve customer transparency and trust
- Risk mitigation – IoT enables companies to proactively address risks, from theft to supply chain disruptions
- Sustainability improvements – AI-driven IoT logistics solutions help reduce fuel consumption and carbon footprints, supporting ESG goals.
Research from McKinsey indicates that implementing advanced digital logistics capabilities can lead to significant operational improvements. Leading logistics players have reported performance enhancements of 10 to 20 percent in the short term and 20 to 40 percent within two to four years.
The future of IoT in logistics
For years, IoT has been positioned as a game-changer for logistics. Now, it’s less about whether companies should adopt IoT and more about how they can actually make it work at scale. The focus is shifting from simple tracking solutions to truly smart logistics technology, where AI and automation drive real-time decision-making. But, there are still hurdles to clear.
Some of the biggest shifts we’re likely to see include:
- 5G and edge computing – Faster, real-time processing will allow logistics companies to make split-second decisions on routing, fleet management, and predictive maintenance without relying on centralised cloud systems.
- AI-powered decision making – Tracking shipments is just the start. AI will analyse IoT data in real time, identifying inefficiencies, predicting disruptions, and automating route adjustments before problems occur.
- Blockchain for transparency – Supply chain integrity is becoming a bigger issue, especially with rising concerns around fraud and compliance. IoT-connected blockchain solutions could lock in shipment data securely, reducing disputes and errors.
- Sustainability as a business imperative – The pressure to reduce emissions is growing, and IoT will play a direct role in measuring and cutting carbon footprints. Fuel efficiency, warehouse energy use, and cold chain optimisation will all be key focus areas.
What’s clear is that IoT alone isn’t the solution, it’s how companies integrate and scale it alongside AI, automation, and sustainability efforts that will determine who stays ahead in the industry.
“IoT is not a new concept but it is pivotal for businesses successfully automating operations and implementing generative AI. You can view IoT as being like a nervous system, collecting and disseminating sensory information. In human biology, blood would carry this information to the brain, which we can imagine as data (lifeblood) and AI (the brain). All three must work together harmoniously to be functional and this same logic applies to managing intelligent operations. As an end-to-end IoT partner, Three Group Solutions works to optimise this whole system, and the connectivity powering it”.
Richard Taylor, Head of IoT Business Development, Three Group Solutions.
How logistics companies can prepare for IoT integration
IoT is changing logistics, but jumping in without a plan can lead to wasted investment and operational headaches. Success depends on clear objectives, stakeholder alignment, and the right technology partners. Here is how companies can set themselves up for a smooth transition.
-
Define clear goals
IoT is not a one-size-fits-all solution. Companies need to pinpoint exactly where it will add value, whether that is real-time shipment tracking, predictive maintenance, or warehouse automation. A focused strategy ensures measurable impact rather than just adding more data with no clear return.
-
Get stakeholder buy-in
Technology is only as effective as the people using it. IoT adoption affects operations, IT, finance, and frontline staff, so securing early buy-in is critical. Leaders need to communicate why it matters, how it will improve efficiency, and what support teams need to adapt.
-
Start small and scale smart
Rolling out IoT across an entire logistics network at once is risky and expensive. A pilot approach such as testing fleet tracking on a specific route or automating inventory for a single product line allows teams to refine processes before scaling up.
-
Choose the right IoT partner
Not all IoT solutions are designed for logistics. The right provider will offer seamless integration with existing systems, real-time analytics, and ongoing support. Companies need more than just hardware. They need a long-term partner that understands the industry’s unique challenges.
