Service revenue growth in industrial manufacturing refers to the systematic expansion of aftermarket income – parts sales, maintenance contracts, field service, repairs, upgrades, and lifecycle support – generated from an OEM’s existing installed base of equipment. It is the single most effective lever for improving margins, stabilizing cash flows, and increasing enterprise value.
How effective? Research shows that for every percentage point of service growth over product sales, enterprise value increases by 50%. Companies that excel in aftermarket operations deliver double the total shareholder returns over 15 years compared to those that don’t prioritize service. And yet, despite these numbers, most OEMs are still structured, staffed, and incentivized to sell new equipment – not to capture the far larger revenue stream sitting inside the equipment they’ve already shipped.
The strategic case has been made. What most OEMs lack isn’t motivation – it’s the operational playbook to execute. This article provides it.
Two OEMs, Same Equipment, Different Outcomes
Consider two pump manufacturers. Similar size, similar product lines, similar installed bases of several thousand units deployed across process industries globally. Both sell the same categories of equipment into the same end markets.
OEM A generates 18% of total revenue from aftermarket. Its service operation is a support function. When customers call with a breakdown, the team dispatches a technician. When customers order parts, the team fills the order. Sales reps spend 90% of their time on new equipment pipeline. Nobody systematically tracks which installed accounts are underbuying parts, which service contracts are lapsing, or which customers are sourcing maintenance from third parties. Service revenue is flat year over year. Leadership blames “market conditions.”
OEM B generates 45% of total revenue from aftermarket. Same market conditions. Its service operation runs as a P&L, not a cost center. A dedicated aftermarket team proactively identifies accounts where parts purchasing has declined, engages customers 90 days before warranty expiration, and uses equipment lifecycle data to time upgrade and overhaul conversations. Field technicians feed observations back into the commercial process. Every service visit generates at least one follow-up opportunity. Service revenue grows 12–15% annually.
The difference between these two OEMs is not product quality, brand strength, or market access. It’s operational design. One waits for revenue to arrive. The other goes and gets it.
What the Numbers Say About Service Revenue Potential
The aftermarket opportunity is not theoretical. Industry data makes the scale concrete:
In construction equipment, 65% of total revenue comes from aftermarket and service. In aircraft engines and mining equipment, it’s 55%. In HVAC systems, 50%. These aren’t aspirational targets – they’re the current reality for the sectors where aftermarket maturity is highest. Industrial OEMs in less mature segments are often capturing half that share, or less.
Aftermarket margins run two to ten times higher than new equipment margins, depending on the aggressiveness of the service model. The most instructive benchmark is Thermo Fisher Scientific – a $42.9 billion manufacturer that generates 40% of revenue from services and 40% from consumables. Equipment accounts for just 20% of their revenue. Their service margins run 36%, compared to 31% on products. They’ve structured the entire company around the aftermarket, and they keep growing by acquiring companies that deepen those revenue streams.
The industry is moving decisively in this direction. A recent PMMI survey found that 96% of OEMs expect parts revenue growth and 94% expect services revenue growth over the next three years. The question is no longer whether to invest in aftermarket. It’s whether your organization can execute fast enough to capture the growth before competitors – including third-party service providers – take it first.
Why 90% of Near-Term Growth Comes From Getting the Basics Right
The loudest voices in aftermarket strategy talk about IoT platforms, digital twins, outcome-based pricing models, and servitization. These are real strategies for mature service organizations. They are the wrong starting point for most OEMs.
One OEM closely examined its aftermarket lifetime value and discovered that 90% of its near-term growth would come from core services – parts, maintenance contracts, and field service optimization – even though initial estimates assumed digital solutions would be the primary driver. The basics, executed systematically, dwarfed the digital opportunity in the near term.
This finding is consistent across industries. The OEMs leaving the most revenue on the table aren’t the ones without IoT sensors. They’re the ones that don’t know which accounts have aging equipment approaching a major service milestone, which service contracts expired last quarter without a renewal conversation, and which customers are buying 30% of the parts their installed equipment should consume. The data to identify these opportunities exists today, in systems the OEM already owns. It’s just not being connected, analyzed, or acted on.
Research suggests that OEMs that understand their customer base, prioritize aftermarket sales, and focus on execution can boost service revenue by 30 to 60% within three to five years – without requiring large investments in capital expenditure, new product development, or cost-reduction programs. That growth is stable through business cycles and can begin generating returns within weeks in some cases.
The path to service revenue growth starts with the basics, not the bleeding edge.
Six Shifts That Separate Growing OEMs From Stagnant Ones
From guessing at the opportunity → to sizing it at every account. Research shows that 60% of industrial companies struggle to identify their target service customers. They know who bought equipment. They don’t know who is operating it, what it needs, or how much service revenue each account should generate. The first shift is calculating the total addressable aftermarket value at every account – based on what’s installed, its age, and its expected consumption – then comparing that against actual capture rate. The gap between potential and actual is the growth opportunity. Without this math, “grow service revenue” is an aspiration, not a plan.
From waiting for service calls → to triggering outreach at lifecycle milestones. Equipment doesn’t fail randomly. Pumps need rebuild kits at predictable intervals. Compressors require overhauls based on operating hours. Warranty periods expire on known dates. Every one of these is a proactive engagement opportunity – and a moment where competitors will step in if the OEM doesn’t. The shift is from responding to breakdowns (reactive) to initiating conversations at the moments that drive decisions (proactive). This requires knowing what’s installed and where it sits in its lifecycle.
From selling service like equipment → to building a dedicated aftermarket sales motion. Equipment sales are high-ticket, long-cycle, relationship-driven. Aftermarket sales are high-frequency, data-driven, and account-specific. Most OEMs ask their equipment sales team to do both – and the aftermarket always loses to the bigger deal. Only 58% of industrial companies have created a dedicated sales team for service, and just 32% have service-specific incentive structures. The OEMs growing fastest have separated the motions entirely: different team, different metrics, different compensation.
From treating field visits as cost events → to treating them as revenue intelligence. Every time a technician visits a customer site, they see things no one else in the organization sees: which equipment is showing wear, which competitor parts are installed, what the customer is planning to replace next year. In most OEM organizations, this intelligence stays in a service report that nobody in sales ever reads. The shift is structural: field service data feeds into the commercial process. Every visit generates at least one follow-up action – a parts recommendation, an upgrade conversation, a contract renewal trigger.
From uniform service contracts → to tiered, value-based service design. Many OEMs offer one or two service contract options: basic and premium. The opportunity is in tiered contract design that aligns price with customer value and OEM margin. A base tier covers essential maintenance. A mid tier bundles parts and priority response. A top tier includes performance guarantees, dedicated support, and proactive monitoring. Each tier increases switching costs, deepens the customer relationship, and captures more revenue per account. The contract becomes a retention tool, not just a revenue line.
From pricing on cost-plus → to pricing on customer value and competitive position. Cost-plus pricing is the default for most OEM service operations: calculate the cost of delivery, add a standard markup, send the quote. The problem is that cost-plus ignores what the service is worth to the customer – which, for mission-critical equipment, is often multiples of the delivery cost. It also ignores competitive dynamics: proprietary services where the OEM has unique expertise can command premium pricing, while commodity services need competitive pricing to prevent displacement. The shift is from one pricing formula to a segmented approach that captures margin where the OEM has leverage and remains competitive where it doesn’t.
What Changes When You Can See the Installed Base
All six shifts depend on a common capability: knowing what equipment each customer operates, what stage of its lifecycle it’s in, and how the customer’s service and parts engagement compares to what the equipment should require.
This is what installed base intelligence provides. It connects the data that already exists across ERP, CRM, and field service systems into a unified view that answers the questions driving service revenue: Which accounts represent the highest growth potential? Which ones are at risk of churning to a third party? Where are the lifecycle milestones that should trigger outreach this quarter? What’s the gap between what each account is buying and what their installed equipment warrants? The OEMs making the six shifts described above aren’t doing it with more headcount or bigger budgets. They’re doing it with better visibility into what they’ve already shipped. (For a detailed look at how this works, see our articles on installed base analytics and spare parts inventory management.)
Frequently Asked Questions
The highest-impact approach combines six operational shifts: sizing the aftermarket opportunity at every account using installed base data, triggering proactive outreach at equipment lifecycle milestones, building a dedicated aftermarket sales team with service-specific incentives, converting field service visits into commercial intelligence, designing tiered service contracts that increase switching costs, and implementing value-based pricing rather than cost-plus. Research shows these levers can boost service revenue by 30–60% within three to five years without significant capital investment.
Reactive service waits for customer-initiated events: a breakdown call, an inbound parts order, a renewal request. Proactive service uses data – equipment age, lifecycle position, purchasing patterns, contract timelines – to initiate engagement before the customer asks. The OEMs growing service revenue fastest have shifted from reactive to proactive models, using installed base intelligence to identify opportunities and time outreach to the moments that drive customer decisions.
Data and AI increase service revenue by enabling OEMs to see their full installed base, calculate the aftermarket potential at each account, predict which customers need what service and when, and prioritize sales effort where the gap between actual and potential revenue is greatest. One industrial OEM used ML-driven analysis of its installed base to generate 20% more leads and create 20% additional bandwidth for its inside sales team – without adding headcount. The key prerequisite is unified installed base data; AI applied to fragmented data produces fragmented results.
Aftermarket service margins are typically two to ten times higher than new equipment margins, depending on the service model. The range is wide because it depends on the mix of services offered: basic maintenance and parts delivery sit at the lower end, while performance-based contracts and proprietary overhaul services can reach margins ten times higher than equipment sales. Across 30 industries, the average aftermarket EBIT margin is approximately 25%. Companies like Thermo Fisher Scientific, which generate 40% of revenue from services, report service margins of 36%.
The two pump manufacturers from the start of this article aren’t hypothetical archetypes. They’re composites of real OEMs operating in the same markets, with the same types of equipment, facing the same competitive dynamics. One generates nearly half its revenue from aftermarket. The other generates less than a fifth. The gap is not market opportunity. It’s operational design.
The six shifts – sizing the opportunity, engaging proactively, separating the sales motion, capturing field intelligence, designing smarter contracts, and pricing on value – are not exotic strategies. They are the operational fundamentals that the highest-performing OEMs have already adopted. Ninety percent of the near-term growth is in the basics. The data to execute exists in systems you already own. The question is whether your organization is structured to act on it.
One OEM is still waiting for the phone to ring. The other already knows which accounts need what, and when.
