When a business directs its products and services toward consumers in a country other than the one in which it is located international marketing takes place. While the overall concept of marketing is the same worldwide, the environment within which the marketing plan is implemented can be dramatically different from region to region.
Common marketing concerns such as input costs, price, advertising, and distribution are likely to differ dramatically in the countries in which a firm elects to market its goods or services. Business consultants thus contend that the key to successful international marketing for any business whether a multinational corporation or a small entrepreneurial venture is the ability to adapt, manage, and coordinate an intelligent plan in an unfamiliar foreign environment.
If departments of exporting become successful then offices could be built in the foreign countries .But the costs of doing business from headquarters plus time differences, language barriers, and cultural ignorance are hindering the company’s competitiveness in the foreign market. Sometimes companies buy firms in the foreign countries to take advantage of relationships, storefronts, factories, and personnel already in place. These offices still report to headquarters in the home market but most of the marketing mix decisions are made in the individual countries since that staff is the most knowledgeable about the target markets.
Local product development is based on the needs of local customers. These marketers are considered polycentric because they acknowledge that each market/country has different needs.
Although firms marketing abroad face many of the same challenges as firms marketing domestically, international environments present added uncertainties which must be accurately interpreted. Indeed, there are a host of factors that need to be researched and evaluated when preparing an international marketing strategy.
Key aspects of any potential foreign market include: demographic and physical environment; political environment; economic environment; social and cultural environment; and legal environment.
Many forms are taken by international market efforts. In several nations the companies that conduct international business often favor what is known as an "individualized" marketing strategy. This approach, which also is often utilized by smaller businesses involved in only one or two foreign markets, typically involves a comprehensive market research component and a significant effort to tailor a product or service to each individual target market. Under this approach, political, social, and economic factors are important components of the marketing process.
