Pricing is one of the four elements of the marketing mix, along with product, place and promotion. An effective pricing strategy is vital for companies who wish to achieve success by finding the price point where they can maximize sales and profits. Companies may use a variety of pricing strategies, depending on their own unique marketing goals and objectives – and also on which industry they represent. Price setting and price getting require discipline, not luck. Companies differ substantially in their approach to price setting but most (whatever the industry) use one of these three strategies: cost-based pricing, competition-based (dynamic) pricing or value-based pricing.
