In order to run a business, whether a retail store, a grocery store, a boutique, a café, a restaurant or a services company, every business has to follow a certain number of general rules, namely concerning the display of prices, the opening hours, the competition, various commercial practices (advertising, sales, distance selling, door-to-door selling, sales to consumers, etc.), as well as different rules which specifically apply to certain sectors only (e.g. Horeca, food, etc.).

Each business who so wishes can also try to develop their activities by responding to tenders within the framework of public procurement contracts.
