In today's economy, successful businesses use three basic elements of marketing:
- Internal marketing in progress;
- Direct short-term marketing;
- Long-term media.
That is why marketing is an operational system of the activity that aims.
- Determining the current and future needs of current and potential customers;
- Study and design of products and / or services designed to meet the needs and requirements of customers;
- In production;
- In the field of standardization;
- In the field of logistics - distribution;
- Promoting these products in the right place and at the right time.
The integrated part of marketing is given by monitoring the needs before and after the process of selling and adapting products and services in the evolution of achieving business objectives. SMEs see marketing as a process that provides a certain market share.
Although the importance of the SME sector and the informal sector is recognized internationally, defining an SME is a difficult task, as each country has its own definition. There is no single, uniformly accepted definition of a small firm (Storey, 1994). Businesses differ in their level of capitalization, sales and employment. Therefore, definitions that use size measures (e.g., number of employees, turnover, profitability, and net worth) when applied to a sector could lead to the classification of all firms as small, while the same definition of size when applied to another sector it could lead to a different result.
