The EEIG, due to its increasing demand by companies around transnational activities, has become an interesting variant of cooperation in different economic fields, such as the establishment of joint purchasing and sales management, joint research and development projects, or cooperation in the area of personnel, such as the provision of training courses. It is an instrument that can be likened to our business network and is viewed positively by the European Union because it is born, develops and grows as a legal entity under transnational Community law that stimulates and implements relations between European partners (a priority objective for the EU). It has a streamlined organisation because it has no major staffing requirements and even the management itself serves as a useful and simple coordination between the parties. It allows resources to be pooled and business opportunities to be increased in synergy without these conflicting, as the entity cannot make a profit, so each actor would then have its share of the profits turned over to itself, although it could offer itself on the market under the joint EEIG banner. It is the ideal tool, therefore, for those who intend to cooperate and pool their energies at a transnational and cross-border level in order to take advantage, in an agile and stronger way, of the various opportunities that the European public programming of funds (with the addition of the NEXT GENERATION EU) and the single market with the integration of economies increasingly offer.
