Guidelines for the submission of e-invoices

The following are the guidelines and information on how to correctly submit e-invoices to the budget user: Ministry of the Interior, the Police and the Inspectorate of the Republic of Slovenia for Internal Affairs.

Ministry of the Interior, together with its constituent bodies – each with its own tax number – conducts its financial transactions  via the Ministry of the Interior's bank account number SI56 0110 0637 0171 132, while Police Directorates that are part of the Police are also independent organisational units that issue purchase orders and, consequently, receive invoices.

 The sorting and routing system of the received e-invoices has been improved with the updated IT system, which now allows individual Police Directorates and the General Police Directorate – which share the same tax number – to receive invoices based on their respective ID (registration) numbers.

The total size of the files attached to an e-invoice may  not exceed 25 MB. If the attachments contain larger volume of data, they must be stored in the large file repository. The total number of characters in the filenames of all the attachments must not exceed 128. If the total length of characters in the filenames of all the attachments exceeds this limit, the attachments must be attached in a zip file created with the Microsoft Windows operating system.

The data required for correct routing of the e-invoice (tax number, bank account number, Business Identifier Code (BIC), buyer's ID (registration) number, the reference number) is specified in each individual contract concluded.

When stating the reference number of a contract or purchase order, invoice issuers should correctly complete the 'legal basis field (Contract ID – the reference number of the contract or purchase order), for example by entering: C1714-25-_ _ _ _ _ _ (please note that only the number of the contract or the purchase order should be entered). The 'Legal basis' field must not be left blank, nor should any additional text or spaces be added to it; please note that it is not permitted to enter more than one contract or purchase order number. Only one contract or purchase order number should be stated.
