A business is an organised economic activity, aiming at producing and exchanging goods and services, carried out by an entrepreneur.

Said economic activity aims at generating wealth, not only by producing goods and services (like farms, industrial and handicraft companies), but also through outlets, transport, bank and insurance activities. Study and research activities cannot be considered as economic activities, and neither can sports, art (the activity carried out by painters, sculptors, etc.) or the activities performed by independent professionals.

Any economic activity is deemed organised if it is carried out by a group of people under the guidance of a professional entrepreneur, within a company. The latter consists of the overall assets (premises, machinery, equipment, furniture etc.) organised by the entrepreneur with a view to carrying out a business activity.
Organising a business means managing and coordinating the company’s personnel and managing its property.

Any activity is considered a professional activity if it is carried out on a regular basis, as opposed to occasionally performed jobs. However, professional activities may also be periodic, as it is the case for organised seasonal activities, which are anyway considered business activities.
