In order to start the operation of any store of any business activity, the issuance of a "Operating License" is required first. In recent years, the legal framework of the Operating Licenses of the Health Interest Stores has changed and now the interested party simply announces the start of operation as well as all the details of his business through the electronic platform "Notify Business" after first obtaining the corresponding Certificate of Installation from the competent service of the Municipality in which the store is located. It is carried out by the natural person or the legal representative of the legal entity that is going to establish or operate the activity in a specific position and is a condition for its establishment or operation respectively. From the submission of the notification, the installation or operation of the activity starts immediately, without the need for a corresponding permit.
