After-sales service is no longer a back-office necessity; for OEMs, it’s a key driver of growth and an essential anchor for nurturing customer relationships. Today, with the intensifying global competition, shrinking product lifecycles, and complex supply chains, manufacturers no longer have the luxury of banking on fresh product launches.
Outstanding service quality and aftermarket assistance are the drivers of its growth. If not managed properly, service systems lead to lost revenues, along with brand reputation and clients shifting to other service providers.
Studies indicate that aftermarket solutions, including spare parts sales, repairs, and service contracts, can make up over 50% of an OEM’s profits. OEMs stand to gain a great deal from digital platforms by improving service delivery, enhancing service relationships, and ensuring a long-term competitive edge.
Why After-Sales Service Matters More Than Ever

As all industries are evolving rapidly, OEMs are now under greater competitive pressure from third-party or local service providers. In these circumstances, after-sales services hold the promise of sustaining revenue, loyalty, and resilience, which is crucial for OEMs to set themselves apart.
From Cost Center to Revenue Driver
Aftermarket sales and services are some of the few streams of revenue OEMs can count on during service operations.
- Growth in Parts Sales: Spare parts sales tend to have higher margins than new product sales. This gives OEMs a reasonably dependable source of profits, especially during economic downturns.
- Contract Services: Maintenance contracts help generate a reliable stream of recurring revenue and ensure customer retention in the OEM’s ecosystem to bolster long-term relationships.
Strengthening Customer Loyalty & Lifetime Value
Customer expectations extend well beyond the initial purchase. Every interaction at the service level shapes brand trust and determines whether customers stay loyal to the OEM.
- Service Team Coordination: Repeated dealings with the service team foster credibility and deepen the relationship well post the initial sale.
- Retention Gains: Overlooking any post-purchase services turns customers towards third-party service centers, resulting in revenue and brand loyalty depletion.
- Lifetime Value Growth: Repeat purchases and longer usage periods motivated by quality service lead to a stretched customer lifetime value.
Strategic Differentiation in Competitive Markets
Due to the swift copying of product features, OEMs depend on service excellence to differentiate themselves. For an OEM to protect its market share and charge a premium fee, it must have superior aftermarket services.
- Premium Positioning: When OEMs respond to and address their customers’ needs promptly and adequately, and offer reliable services, they are entitled to charge higher prices, which is in line with the overall value the customers derive.
- Digital Edge: If OEMs decide not to invest and integrate digital platforms to streamline their service operations, they stand the chance of losing their market share.
- Global Competitiveness: Strongly developed service ecosystems allow OEMs to compete in different markets even against stiff competition from independent service providers.
Key Challenges OEMs Face in After-Sales Service

For many OEMs, the after-sales service is still under-optimized. Obsolete systems, inefficiencies, and a lack of investment not only stifle growth but also reduce customer loyalty.
Fragmented Systems & Legacy Processes
A significant number of OEMs still depend on antiquated inventory and dealer management systems. Such fragmented systems not only bog down processes but also escalate mistakes and deteriorate the quality of service.
- Disconnected Data: The absence of integrated systems causes a breakdown in communication channels between OEMs, dealers, and customers. This leads to slow responses and decreases overall productivity.
- Outdated Processes: Overreliance on fragmented systems poses significant challenges to updating, sharing, and tracking information, thereby creating operational delays.
- Ineffective Scalability: Outdated systems are inefficient in managing spread-out dealer networks, thereby posing a challenge for OEMs to provide uniform services on a global scale.
Lost Revenue from Incorrect or Delayed Parts Orders
Incorrect identification of spare parts results in revenue loss. Studies indicate that 25-50% of OEM spare parts sales leak to third parties.
- Catalog Errors: An outdated or poorly maintained catalog causes confusion and leads users to counterfeit parts.
- Misidentification & Wrong Orders: When parts are misidentified or when part supersession updates are missing, dealers may order obsolete components, resulting in wrong deliveries. This not only frustrates customers but also adds shipping costs, return logistics, and administrative burden.
- Lack of Order Tracking System: Frustrated customers are less likely to return due to the longer order lead time caused by inefficient order management systems.
- Revenue Leakage: Each opportunity to secure a sale that is missed not only weakens profitability but also strengthens the position of aftermarket vendors.
Warranty Management & Return Complexities
OEMs incur increasing expenses due to the manual processing of warranty claims and returns. Fraudulent claims, coupled with processing delays, harm both profitability and customer trust.
- Manual Processing: The paper-based system is slow, error-prone, and fraud-prone.
- Fraud Exposure: Without automated checks, fraudulent claims are easier to make, which escalates costs for OEMs.
- Customer Frustration: The wait for claim approval dampens the satisfaction OEM customers derive from the service and likewise dampens the optics of the relationship.
Language and Global Distribution Barriers
The OEMs work in numerous different regions, which pose challenges in effective communication as well as logistics. The quality of global services is greatly affected by the language barriers and the lack of uniform documentation.
- Localization Issues: Inefficient methods of translating service documents and manuals lead to further communication problems.
- Regional Variations: Different markets require different service processes, which legacy systems are unable to support.
- Global Coordination: Disconnected supply chains decrease response time and create failures in spare parts distribution.
Underinvestment in Service Innovation
OEMs tend to focus on new product launches and ignore the sustained value offered by their aftermarket services. This lack of investment diminishes the ability to compete in today's service-based economy.
- Product-Centric Approach: OEMs should balance their focus between product innovation and strengthening their aftermarket service strategies, as services often deliver sustained profitability and long-term customer value.
- Outdated Systems: Not embracing digital platforms stunts growth opportunities and limits customer engagement.
- Missed Opportunity: Service innovation by other players enables them to enjoy better margins and market leadership.
Emerging Industry Trends Shaping After-Sales Service

The innovation OEMs introduce is driving dramatic transformations in after-sales service and support. Technologies are evolving, as are customer needs, and they are reshaping the methods of providing services, support, and monetization globally.
Digital Transformation of Service
OEMs are adopting digital platforms for service lifecycle management, including online portals, mobile apps, and aftermarket software solutions, in an attempt to shorten service cycles and improve their accuracy.
