The Interdependence of Products and Services: Complementary Roles

Think about the last time you bought a car or booked a flight. In both cases, you were paying for far more than a physical object or a single transaction. The car came with a service network you would depend on for years, and the flight only existed because of a very expensive piece of machinery sitting on a runway. Products and services are rarely standalone offerings. They lean on each other constantly, and understanding this relationship is one of the more practical ideas in services marketing.

Why products and services rarely stand alone 🔗

Marketers have long argued that almost nothing sold in the market is a “pure” good or a “pure” service. Instead, most offerings sit somewhere on a spectrum, with soap and salt near the tangible end and something like a haircut near the intangible end. Everything else, from a laptop to a hospital visit, falls somewhere in between, blending goods and services in different proportions to meet what the customer actually needs. This way of thinking is often called the product-service continuum, and it is a useful lens for understanding why companies can’t treat the physical product and the surrounding service as separate business decisions.

The goods-services continuum 🔗

At one end of this continuum are goods that need almost no service support to be useful. At the other end are services that involve no physical product at all, such as a consulting session or a yoga class. In between sit the vast majority of real-world offerings. A washing machine, for instance, tilts heavily toward the goods side but still depends on installation, repair visits, and spare parts availability. A restaurant meal is often described as a near-equal blend, since the food and the dining experience matter almost equally to the customer, as explained in this overview of the product-service continuum. The position on this continuum isn’t fixed either. A brand can deliberately shift its offering by adding more service value, such as extended warranties, or by adding physical touchpoints to a service, such as branded merchandise at a gym.

When products need services to succeed 🔗

The more technologically advanced or expensive a product gets, the more it tends to rely on services for its full value to be realised. Cars are the textbook example. A vehicle is a complex mechanical and electronic system, and very few buyers would purchase one without some assurance of maintenance, repair, and parts availability. This is why every car sale today is bundled with a warranty period, scheduled service packages, and often roadside assistance. Similarly, air conditioners and other appliances that need installation and periodic upkeep sit closer to the “goods” end of the spectrum but still depend heavily on delivery and installation services to actually work for the customer, as noted in this explanation of the goods and services continuum.

Televisions follow a similar pattern. A customer buying a smart TV is also buying the promise of a working help desk, an in-home repair technician, and spare parts if something breaks down years later. If any of these services are weak or unavailable, the perceived value of the product itself drops, even if the physical unit works perfectly at the point of sale. This is why electronics and automobile companies invest so heavily in after-sales infrastructure rather than treating it as an afterthought.

Warranties and after-sales support as value drivers 🔗

Warranties, annual maintenance contracts, and service centre networks are not just cost centres for a company. They are competitive tools. A brand with a wider and more reliable service network can often charge a premium or win customer loyalty even if a competitor’s core product is technically similar. This is particularly visible in the Indian passenger vehicle market, where Maruti Suzuki’s service network has serviced over 24.5 lakh vehicles in a single month, a scale the company attributes directly to decades of investment in building service reach before it even focused on maximising vehicle sales. This shows how closely product success and service infrastructure are tied together in practice, not just in theory.

When services need products to exist 🔗

The dependency runs in the other direction too. Many services simply cannot be delivered without a supporting physical product. Airline travel is the clearest example. A passenger is technically buying a service, being transported from one place to another, but that service is entirely impossible without a capital-intensive physical asset: the aircraft. The airline product is best understood as a mix of tangible and intangible elements, where things like the aircraft, seating, and airport lounges represent the tangible layer, while crew behaviour and overall customer experience represent the intangible layer, as detailed in this study of the airline business.

Other examples follow the same logic. A gym membership is a service, but it depends on treadmills, weights, and a functional building. A cloud storage subscription is a service, but it depends on physical servers sitting in a data centre somewhere. In each case, the “product” isn’t the point of sale, but without it, the service has nothing to run on.

Kotler’s five categories of offerings 🔗

Marketing scholars have tried to formalise this blend of goods and services into distinct categories, based on how much of each element a typical offering contains. This classification helps explain why some businesses are fundamentally product companies with a service layer, while others are fundamentally service companies that need a product to operate.

The business case for integrating products and services 🔗

This interdependence isn’t just an academic observation. It shapes how competitive companies design their entire business model. One of the most well-known examples is Rolls-Royce’s aircraft engine business. Instead of only selling engines outright, the company introduced a model where airlines pay a fixed rate per flying hour for engine performance, maintenance, and support bundled together. Under this arrangement, Rolls-Royce’s “Power-by-the-Hour” programme, first introduced in 1962, aligned the manufacturer’s incentives with the airline’s needs, since Rolls-Royce only earns well when its engines perform reliably, not when they need repeated repairs.

This approach, often called servitization, reflects a broader shift in how companies compete. Rather than treating the product sale as the end of the relationship, businesses are increasingly designing the product and its supporting service as a single integrated offering from the start. This tends to improve customer retention, create more predictable revenue, and reduce the risk of losing customers to a competitor with a marginally better product but a worse service experience.

How Indian companies are building this integration 🔗

Indian businesses have adapted this thinking to local market conditions. Beyond expanding service centres, some automakers have started blurring the line between owning a product and subscribing to a service altogether. Car subscription programmes, for instance, bundle the vehicle, insurance, maintenance, and roadside assistance into a single monthly payment, letting customers use a product without the traditional burden of ownership. This model effectively turns a tangible good into something closer to a service, showing how flexible the boundary between “product” and “service” really is once a company chooses to design around customer convenience rather than a one-time sale.

This pattern extends well beyond automobiles. Consumer electronics brands bundle extended warranties and doorstep repair visits with premium appliances. Telecom companies bundle handset financing with data plans. Even educational institutions increasingly bundle course material (a product) with mentorship and placement support (a service). In every case, the underlying logic is the same: customers rarely evaluate a product or a service in isolation. They evaluate the complete experience.

What this means for marketers 🔗

For anyone studying or working in marketing, the practical takeaway is straightforward. Product decisions and service decisions cannot be made in silos. A pricing strategy for a product needs to account for the cost of supporting services. A service design needs to account for the reliability of the underlying product. Competitive advantage increasingly comes not from having a slightly better product or a slightly friendlier service desk, but from designing both together so that neither one becomes a weak link that drives customers to a competitor.

This also changes how companies should measure success. A car company that only tracks vehicle sales is missing half the picture if it isn’t equally tracking service centre wait times and warranty claim resolution speed. An airline that only tracks ticket sales is ignoring the fact that a single grounded aircraft can undo months of goodwill built through excellent cabin service. Interdependence means that weaknesses on one side of the offering can quietly undermine strengths on the other.

What do you think? 🔗

Next time you buy something, try identifying where it sits on the goods-services continuum, and notice how much of your satisfaction actually comes from the service layer rather than the product itself. Can you think of a brand you trust primarily because of its after-sales service, even though a competitor’s core product might be just as good?
