Event Supplier and Services Association (ESSA) is a trade association representing contractors and suppliers of goods and services to the exhibition industry. It shares a secretariat with its sister organisations, Association of Event Organisers (AEO) and Association of Event Venues (AEV) and thus benefits from the central information source. The development of a closer relationship and understanding between organisers their suppliers and venues can only benefit the industry as a whole.

This closer relationship is partly demonstrated by way of joint working groups covering a range of issues into which all sides of the industry have an important input. It is also a major step towards the goal of enabling the industry to speak with a united voice when striving to increase its share of the marketing cake.
