In marketing and microeconomics, customer switching or consumer switching describes "customers/consumers abandoning a product or service in favor of a competitor". Assuming constant price, product or service quality, counteracting this behaviour in order to achieve maximal customer retention is the business of marketing, public relations and advertising. Brand switching--as opposed to brand loyalty is the outcome of customer switching behaviour.
Variability in quality or market price fluctuations--especially a rise in prices--may lead customers to consult price comparison services where alternative suppliers may be offered. Declining customer satisfaction may be due to poor service quality but also--to a lesser degree--be a symptom of boredom with the brand of choice. Brand loyalty can be very strong, however, and the longer a commitment to a brand lasts, the stronger the ties will usually be.
Because of the dominant role of pricing, market tactics like penetration pricing have evolved to offer a convincing incentive for switching. Along with these are the factors like service inconvenience, poor location, ethical issues like hard selling or unsafe products and also change in customers' income levels. Another approach is the advertisement of vaporware that seemingly will offer newer or better features than established products without actually possessing any innovation.
Switching is a significant business factor affecting revenues for companies providing continuously delivered services, as is the case for the energy market as opposed to sectors providing products that stimulate non- or sparsely recurring purchase because of the durability of the product or a general orientation towards casual customers.Energy customer switching is a significant risk or success factor for energy suppliers.
