Switching Costs and Lock-ins describe the costs and mechanisms that make it harder for a customer to change to another provider. From the provider’s perspective, they are a strategic instrument for customer retention and building competitive advantages. From the customer’s perspective, they can be both acceptable (because the provider delivers genuine added value) and problematic (because one cannot switch despite dissatisfaction).
Lock-ins arise through various mechanisms: technological dependency (proprietary formats, incompatible systems), contractual binding (minimum terms, notice periods), data dependency (all data resides with the provider and is difficult to export), or network effects (the social network where all contacts are). Companies that have built heavily on Microsoft 365, for instance, face high switching costs due to file formats, workflows, integrations, and trained employees. The lock-in becomes a competitive advantage for Microsoft and a strategic dependency for the customer.
The concept traces back to Michael Porter and was transferred to the business model context by Osterwalder. The decisive question for one’s own strategy: Are customers retained through genuine added value or only through switching barriers? The latter works only until a competitor makes switching easy enough.
