(13)Member States should remain competent, in accordance with Union law, to apply the provisions of this Directive to areas not falling within its scope. Member States may therefore maintain or introduce national legislation corresponding to the provisions of this Directive, or certain of its provisions, in relation to contracts that fall outside the scope of this Directive. For instance, Member States may decide to extend the application of the rules of this Directive to legal persons or to natural persons who are not consumers within the meaning of this Directive, such as non-governmental organisations, start-ups or small and medium-sized enterprises. Similarly, Member States may apply the provisions of this Directive to contracts that are not distance contracts within the meaning of this Directive, for example because they are not concluded under an organised distance sales or service-provision scheme. Moreover, Member States may also maintain or introduce national provisions on issues not specifically addressed in this Directive, such as additional rules concerning sales contracts, including in relation to the delivery of goods, or requirements for the provision of information during the existence of a contract.
