Unfortunately, you can not simply sell random stuff on the Internet however you find it good for you. Before you start selling, you must devote the necessary time to research the standard rules which apply when it comes to e-Commerce. This way, you will be prepared for any situation that can occur in near future.

Although each European state has the right to establish certain national rules regarding e-Commerce and its implementation, there are common regulations, establishing standard rules in the EU on various issues that are defined in the EU's Directive 2000/31/EC on electronic commerce. In a nutshell, what you should know concerning the legal aspect of the e-Commerce is the following:

• In every EU country, electronic contracts must be given equivalent legal status to paper contracts.
• You must ensure to publish basic information on your activities (your details, the main characteristics of the goods/services you are selling, delivery and return options, information about payment, pricing and additional charges, conditions for resolving disputes, etc.) in a permanent and easily accessible form.
• You must ensure that advertising follows certain rules, such as that it is clearly identifiable as advertising, the person responsible for it is clearly identifiable, the promotional offers or competitions are clearly identifiable, and the conditions are easily accessible and presented in clear and simple terms.
• If you send out spam emails, you must regularly consult and respect opt-out registers, to which people who do not wish to receive such emails can sign up.

Make sure to include as much of the above-mentioned information as possible. You must ensure that your e-Commerce shop has basic and intuitive structure, so customers can easily navigate and find the necessary information. Also, do not forget to follow the General Data Protection Regulation and include a dedicated section concerning consumer rights.
