Pricing models are strategies used by businesses to determine how much to charge for their products or services. Common models include cost-plus pricing, where a fixed percentage is added to the cost of production, and value-based pricing, which sets prices based on the perceived value to the customer. Other models include subscription pricing, where customers pay a recurring fee for ongoing access, and dynamic pricing, which adjusts prices based on demand and market conditions. Each model has its advantages and is chosen based on factors like target market, competition, and overall business goals.
