When the Machine Stops
A machine stops working, production slows down, and someone in the factory starts looking for the right spare part. In that moment, the customer is no longer thinking about the original purchase, they are thinking about how quickly they can get up and running again.
This is where the real customer relationship often shows itself.
When working with manufacturers, one thing becomes clear surprisingly often: even organisations with sophisticated ERP systems and complex product structures still handle spare parts ordering through fairly manual processes. Customers send an email or make a call, someone in support searches through documentation, and sales eventually creates the order.
The process usually works, but it is rarely fast and it rarely scales particularly well.

Why Spare Parts Become a Bottleneck
In most cases, the challenge isn’t that spare parts are complicated. Manufacturers typically understand their own products and components extremely well.
The real issue is that customers rarely have access to that same knowledge.
Information about spare parts tends to be scattered across systems and documents. Product structures often live inside the ERP system, while manuals and diagrams are stored in PDFs or internal documentation systems. Service teams know the right components because they have worked with the products for years, but that knowledge is not always structured in a way customers can easily navigate themselves.
So when something breaks, customers depend on internal teams to identify the correct part. What should be a simple reorder turns into a small internal workflow involving multiple people and systems.
Across a large installed base of machines, these small interactions add up quickly and create a surprising amount of operational friction.

The Shift Toward Self-Service Aftersales
This is why more manufacturers are starting to rethink how spare parts are handled after the original sale.
Instead of routing every request through internal teams, they make spare parts, documentation and ordering flows available through digital self-service environments. Customers can identify parts directly from product structures, access documentation when they need it, and reorder components without having to wait for someone internally to guide them through the process.
Platforms such as Truvio enable this by connecting product data, ERP information and commerce functionality in one consistent experience.
The technology itself is rarely the most interesting part. What really changes is the level of clarity customers suddenly have. Instead of relying on internal knowledge, they can see the same product structures, spare part relationships and ordering options that internal teams have always used.

Creating Consistency Across Your Partner Ecosystem
Another challenge manufacturers often face is consistency across their partner network.
Dealers in different markets frequently operate with different levels of information and support. Some rely on spreadsheets, others on emails, and some simply contact their internal sales representative whenever they need something.
This leads to inconsistent experiences across the partner ecosystem and increases the risk of pricing errors, incorrect product configurations and slow ordering processes.
With a well-structured partner portal, the same product data, pricing logic and configuration rules are available across the entire dealer network. Dealers gain the information they need to operate more independently while the manufacturer retains full control over product data and processes.
The result is a more consistent experience for partners and a much more scalable operating model for the manufacturer.

Scaling Aftersales Without Scaling the Team
Another pattern that often appears in manufacturing organisations is how much internal capacity is tied up in answering relatively simple requests.
Service teams spend time identifying parts that customers could potentially find themselves. Sales teams process manual reorders, while support teams respond to questions that would disappear if the right information was accessible.
A well-designed self-service environment changes that dynamic quite significantly. Customers gain direct access to product structures, documentation and ordering capabilities, while internal teams can focus on more complex service situations where their expertise actually creates value.
As the installed base of machines grows, the organisation can therefore support more customers without continuously increasing the size of internal teams.

Aftersales as a Growth Engine
For many manufacturers, the installed base of equipment in the market is already substantial. What is often underestimated is how much commercial potential exists after the original sale.
When spare parts are easy to find, easy to understand and easy to order, customers naturally return more often. Reorders become simpler, maintenance becomes more predictable, and the relationship between supplier and customer becomes more continuous.
Aftersales stops behaving like a reactive support activity and starts functioning more like a stable revenue stream.
Just as importantly, the manufacturer becomes easier to work with and in B2B markets that alone is often enough to build long-term loyalty.

Together, Niels Brinkø from Kruso and Lars Byg Holm from Truvio explore how manufacturers reduce friction in B2B sales by connecting PIM, ERP and commerce platforms.
