Switching costs

The cost a customer faces in changing from one supplier to another can matter more to competition than the price itself. Switching costs are what make customers stick.

Switching costs are the costs, in money, time, effort, or risk, that a customer incurs when changing from one supplier, product, or technology to another. They are a powerful source of customer retention and market power, because they make customers reluctant to leave even when a rival offers something better or cheaper.

The many forms of friction

Switching costs come in many guises. There are direct financial costs, such as cancellation fees or the price of new equipment. There are learning costs, the effort of mastering a new system after becoming proficient in the old. There are the costs of transferring data, content, or settings that are tied to the current provider. There are the costs of disruption and risk in changing something that works. And there are relational and contractual ties. Together these raise the hurdle a customer must clear to switch, and the higher the hurdle, the more captive the customer.

A source of power and profit

For firms, switching costs are valuable because they lock customers in and soften competition. Once customers have incurred the cost of adopting a product and would face a cost to leave, the firm can charge more, neglect them somewhat, or weather a rival's better offer, because the customer's alternative is not just the rival's price but the rival's price plus the cost of switching. Much strategy, particularly in software, platforms, and subscriptions, is the deliberate construction of switching costs, often by accumulating the customer's own data, habits, and integrations inside the product.

The customer's defence and the policy concern

Customers, aware of being locked in, increasingly resist switching costs, favouring open standards, data portability, and contracts without heavy exit penalties. Competition authorities, too, scrutinise switching costs, because high ones blunt competition by insulating incumbents from rivals and entrants. Measures to lower switching costs, such as number portability in mobile phones or rules requiring data to be transferable, are deliberate attempts to restore the competition that lock-in suppresses.

Switching costs are among the most important and least visible forces in competition, the friction that determines whether customers can act on better offers or are held in place. They explain why markets do not always reward the best product, why incumbents can persist despite superior rivals, and why so much of both strategy and competition policy turns on how hard it is for a customer to walk away.
