Aftermarket parts and services have always been a steady source of revenue for manufacturers. Once the machine is sold, companies rely on parts, maintenance, and service contracts to create long-term value. But in many industries, third-party suppliers and independent shops often win this business instead.

Data changes that equation. By using the information already generated by machines in the field, OEMs can not only improve the customer experience but also strengthen their position in the aftermarket.

Why OEMs Lose Out Today

When a machine breaks down, customers often go to whoever can fix it fastest or cheapest. Third-party providers fill that gap by stocking common parts and offering quick service. OEMs, despite having deeper product knowledge, are at a disadvantage because they lack visibility into how machines are performing in real time.

This lack of visibility means:

• Parts demand is hard to predict, leading to shortages or overstock.

• Maintenance is often reactive, not proactive.

• Customers see OEM services as slow, expensive, or inconvenient compared to alternatives.

How Data Creates an Advantage

Machine data can change this dynamic in several ways:

1. Predictive maintenance. By monitoring usage and wear, OEMs can anticipate failures before they happen and position parts accordingly.

2. Smarter inventory. Data allows manufacturers to forecast which parts will be needed, reducing costs while ensuring availability.

3. Customer trust. Sharing data-backed insights helps customers understand when and why a part needs replacing, which builds credibility.

4. Integrated services. OEMs can bundle data-driven insights with service contracts, creating a smoother and more valuable experience for customers.

In short, data allows OEMs to act before a machine fails, rather than reacting after the fact.

The Business Case

This is more than a technical improvement. It is a competitive strategy. Aftermarket parts and services often carry higher margins than the original equipment. They are also a key way to keep customers tied to the brand over the long term.

By building a stronger aftermarket presence with data, OEMs can both protect revenue and create new opportunities. For example, service contracts based on actual machine usage rather than fixed schedules, or subscription models where uptime is guaranteed.

A Shift in Perspective

Many OEMs still treat the aftermarket as an add-on rather than a core part of their strategy. That mindset is risky in a market where customers expect fast, reliable service backed by real information.

The companies that recognize the role of data in aftermarket services will not just improve margins. They will strengthen customer loyalty and position themselves as partners, not just suppliers.
