Lock-In

The condition where switching to a competitor is so costly—in money, time, effort, or lost data—that customers stay even when alternatives are objectively better. Switching costs create lock-in: enterprise software requires retraining; ecosystems (Apple) require replacing multiple integrated devices; data formats prevent migration. Lock-in is the most reliable source of recurring revenue and the most common source of customer resentment. It can be built deliberately (proprietary formats) or emerge naturally (learning curves, data accumulation).

When to use it

When evaluating competitive moats—lock-in is one of the strongest; when assessing technology or vendor choices—switching costs compound over time; when a customer seems irrationally loyal or disloyal; when building product strategy around retention versus acquisition.

How it can help

As a strategist, evaluate lock-in from both sides. For your business: what switching costs keep customers? Are they sustainable (genuine value from integration) or fragile (artificial barriers that competitors can break)? For your dependencies: where are YOU locked in? How much would it cost to switch your CRM, cloud provider, or core technology? The best lock-in comes from genuine value that increases over time (network effects, data accumulation)—not from artificial barriers that create resentment.
