If your edge is a feature that a competitor can add to its next release, budget as though it will. The more useful question is what a rival would have to change about its business to deliver the same result at the same price. A moat, in this sense, is an advantage that stays valuable to the customer and remains costly for a competitor to match. A head start buys time.
Costco's fiscal 2024 annual filing describes a membership warehouse model that pairs low prices with a limited assortment. Costco says the resulting sales volume and inventory turnover, together with operating efficiencies such as buying in volume, let it operate at lower gross margins than most retailers. A rival can lower the price on a box of detergent this weekend. Matching the economics of the wider model is a different question.
Southwest's 2024 annual filing makes a related point about complexity. The airline describes using one aircraft type, the Boeing 737, and says that choice historically simplified work including maintenance and training. These are companies describing their own operations. The filings illustrate choices that fit together; they do not prove those choices are impossible to copy or that they work at a startup's scale.
Measure the cost of keeping your promise
Suppose a hypothetical repair shop promises next-day service for two models of commercial coffee machine. It stocks the parts it uses most often and trains technicians to diagnose those models from photos before making a visit. A larger service company could put next-day repair on its website. To match the promise profitably, it would still need parts close enough to the machines and enough jobs nearby to keep its technicians busy.
Start with one route. Track the share of eligible jobs completed the next day and count return visits as part of the same job. Work out what is left from each repair after parts and technician time, including travel. The owner should also track whether a customer calls again or refers another shop, since finishing a repair on time matters commercially only if the customer values it enough to come back or tell someone else. Faster service that loses money on each job is a promotion. A profitable repair that customers won't pay extra for or choose again is a weak basis for expansion.
The shop has a choice. The repair shop might turn away calls for other machines even when the calendar has room. Taking those calls could fill tomorrow's schedule while making the parts shelf harder to stock and the service promise harder to keep. But the restriction is only worth defending if enough local buyers own those machines. Count the calls it refuses.
Take the competitor's side before investing further. If a national chain can put a technician on the same route with the same parts and no meaningful extra cost, don't count the route as protection. Use your lead to improve something that takes time to reproduce, such as a reliable diagnosis process built from repeat jobs. Keep the next investment tied to a result you can measure: fewer return trips without a drop in the share of jobs you finish on time.
