Digitalization is fundamentally changing technical customer service. Machinery and plant manufacturers can work more efficiently, reduce costs, and build stronger customer relationships. This article answers the most common questions about digital services—from the basics to the Internet of Things (IoT) and customer portals, all the way through to implementation.
Basics
What is digital technical customer service?
Digital service refers to the use of technologies such as the Internet of Things (IoT), artificial intelligence, cloud systems, and augmented reality to automate and improve service processes. Instead of waiting reactively for malfunctions to occur, machine data is used to plan maintenance, process requests digitally, and engage customers through portals. At its core is a seamless, interconnected database rather than isolated, siloed solutions.
What are the benefits of digitization in the service sector?
The key benefits include greater efficiency through the automation of routine tasks, fewer unplanned downtimes thanks to predictive maintenance, and stronger customer loyalty through transparent, rapid communication. Added to this is a point that is often underestimated: the service business in mechanical engineering frequently generates higher margins than new equipment sales, and a digitized installed base makes it possible to systematically tap into this aftermarket potential.
What technologies are used?
Key technologies include IoT sensors for condition monitoring, AI for predictive maintenance and decision support, mobile apps for field service, and cloud and portal solutions for customer access. What matters is not the individual technology, but how they work together on a shared platform.
What is the difference between reactive and proactive service?
Reactive service begins when the customer reports a malfunction—by which time the machine has often already come to a standstill. Proactive service identifies problems before they lead to a breakdown: condition data from the system triggers a service procedure while the machine is still running. The economic difference is significant, because unplanned downtime at the customer’s site is the most expensive type of service event. Digitalization is essential for transitioning from a reactive to a proactive model.
How is the installed base related to digital services?
The installed base—all machines in the field—is the foundation of every digital service. Only by knowing which system is running where, in what configuration, and when it was last serviced can a company proactively offer service or sell replacement parts in a targeted manner. A structured inventory of the installed base transforms scattered service data into a usable foundation for maintenance, sales, and decision-making.

IoT and Predictive Maintenance
What is predictive maintenance, and how does it work?
In predictive maintenance, sensors monitor a machine’s condition in real time. AI-powered analyses detect wear patterns early on, so maintenance is performed when it’s needed—not according to a rigid schedule and not only after a breakdown. This reduces unplanned downtime and optimizes the use of personnel and materials.
What machine data is relevant for maintenance?
The following are particularly significant:
- Vibration data for detecting wear in rotating parts,
- Temperature measurements of critical components,
- Oil analyses to detect contamination and wear,
- Ultrasonic measurements to detect leaks and friction,
- RPM, energy consumption, and operating time serve as the basis for calculating maintenance intervals.
Only in the context of the plant—series, configuration, history in the digital machine file —do these measurement values become reliable indicators rather than false alarms.
How do you implement an IoT maintenance system?
A step-by-step approach has proven effective: start with a pilot project on a single piece of equipment and document the results; select appropriate sensors and a secure data transmission method; and finally, integrate analytics tools into maintenance management. Continuous analysis of the data leads to targeted maintenance planning.
Customer Portals and Self-Service
What features should a customer portal offer?
A good portal covers three areas: documentation (specifications, manuals, catalogs), service (maintenance scheduling, repair appointments, trouble reports), and ordering (spare parts catalog, availability check, order history). Seamless integration with existing systems, such as ERP, ensures that inventory levels and prices are accurate in real time.
Is a self-service portal cost-effective?
Yes, in two ways. Customers can resolve routine issues on their own around the clock, which increases satisfaction. At the same time, the portal significantly reduces the workload on the back-office staff because the majority of recurring inquiries no longer need to be handled manually. A self-service interaction is many times cheaper than a personal service call.
How does the digital spare parts ordering process work?
Today, B2B customers expect an ordering process that is just as intuitive as in B2C. Precise part identification via machine-specific catalogs is key—ideally through an interactive 3D model where the customer clicks on the assembly and orders the correct part from the bill of materials.

AI and Decision-Making in Customer Service
How does AI support technical service?
AI is increasingly taking over routine tasks—from ticket classification to chatbots for standard inquiries to preparing service cases. The greater impact, however, lies in decision support: What is actually broken with this system, and what needs to be done? Service Decision Intelligence (SDI) combines data from ERP, Salesforce, IoT, and documentation to generate a well-reasoned recommendation with source references. Humans continue to make the final decision, but on a reliable basis—which is required anyway for security-related cases under Article 22 of the GDPR and meets the requirements of the EU AI Act, effective August 2, 2026.
What role does augmented reality play in customer service?
Augmented reality is particularly useful for remote maintenance: Technicians receive additional information and step-by-step instructions directly in their field of view, and experts can be brought in remotely. This makes complex tasks more precise, reduces errors, and saves on travel.
Introduction
How do you get started with digital transformation in the service sector?
Implementation is achieved in four steps:
- Analyze the current situation: review existing service processes and identify areas for improvement.
- Select the right technologies: field service management, mobile service apps, tools for managing the installed base, and analytics tools.
- Involve employees: Offer training and communicate the specific benefits.
- Introduce gradually: start with pilot projects and roll out the solutions step by step.
What are the most common obstacles—and how can you overcome them?
The most common challenges are a shortage of skilled workers, internal skepticism, and technical complexity. Open communication and regular training help counter skepticism, significantly increasing acceptance. Resource constraints can be mitigated by gradually implementing prioritized projects, and collaborating with an experienced partner reduces technical risk. A clear strategy with measurable goals, active change management, and continuous employee development are essential.
How do you measure the success of service digitization?
A few key metrics are particularly meaningful: the first-contact resolution rate (the percentage of cases resolved on the first contact), the average response and repair times, the self-service rate, and customer satisfaction as measured by the Net Promoter Score. In addition, analytics tools show which content on the portal is being used and where customers are getting stuck. These metrics fuel a continuous improvement process rather than a one-time performance review.
Customer portals on Salesforce with logicline
For companies that already use Salesforce, a customer portal on this platform is the obvious choice: customer, asset, and service data are already integrated, the sales and service teams are directly connected, and no new silos are created. logicline provides its own templates for the Salesforce Experience Cloud and enhances the portal with a spare parts web store, a digital machine file, and integration with proven partner solutions.
Conclusion
Digitalization in technical customer service is not a trend, but a prerequisite for competitiveness. The path to success involves a structured database, interconnected processes, and—where AI supports decision-making—transparency. A step-by-step approach with clear benefits at every stage is crucial.
