In the new Single Desk Information System (SSU) architecture, the Third Party Subsidiary Solution (SSET) is the IT component that can be chosen by a Third Party to interact with the SUAP Back Offices. In particular, it is an application that will be provided in subsidiarity to all the Entities that do not have their own Third Party Back Office component or that choose not to equip themselves with a Third Party Back Office component provided by Regions or market operators.

The Third Party Subsidiary Solution will start operating on July 26, 2025, the date on which the Single Desk Information System (SSU) will become functional and operational throughout Italy. SUAP practices, started before that date, will necessarily have to complete their process on the platforms on which they were instructed.

The Subsidiary Solution can be used on a temporary or permanent basis. In the first case, Third-Party Authorities that fail to implement their own management system or Third-Party Back Office component by 25 July 2025 may use the Subsidiary Solution for Third-Party Authorities(SSET), subject to prior subscription to the service. Subsequently, once they have completed the adaptation of their Third-party Authorities Back Office component (BOET), they may, by updating the data in the accreditation section of the Impresainungiorno web portal, notify MIMIT of the use of a new component (subject to technical verification of its compliance with MIMIT, in compliance with the provisions of Article 7 of the new Technical Annex to the Presidential Decree 160/2010). In the second case, the authority will have to join the same SSET and, during the accreditation phase, select it among the Third-party Authorities Back Office components present in the Catalogue, in order to allow the mapping between the authority and the component used.

Adhesion to the Subsidiary Solution for Third-party Authorities

The adhesion process is digitised and does not involve any formalities vis-à-vis the Chamber of Commerce or any other entity. In order to join the Third-party Authorities Subsidiary Solution, three entities must first be identified:

•     The Digital Transition Manager or (RTD), who must necessarily be registered in the IPA - "Index of Digital Domiciles of Public Administration and Public Service Managers";
•  The Legal Representative of the Third Party Authority, i.e. the person who will be in charge of signing the adhesion contract;
•  The System Administrator, the administrative-technical person who will supervise the entire System.

Once these three subjects have been identified, the adhesion process will involve the following procedure:

1.     The Digital Transition Manager, after having authenticated to the dedicated portal, using strong authentication methods, such as SPID or CNS, must fill in a form specifying his/her personal data, the personal data of the Legal Representative, the personal data of the Third-party Authority and the personal data of an Administrator of the Third-party Authorities Subsidiary Solution (SSET);
2.  Once filled in, the form must be downloaded and signed by the Legal Representative of the Third-party Authority;
3.    The form must be uploaded again, complete with signature (in CADES format) and all the required information, on the online platform through the dedicated page;
4.  The system will verify the veracity of the information uploaded by the Digital Transition Representative, therefore in the event of anomalies, an e-mail will be sent to resolve the discrepancies found; in the event of a positive outcome, on the other hand, the designated Administrator will receive an e-mail through which he/she will be able to log in for the first time within a predefined time and complete the platform membership process.

The authority will have to configure its own offices: the SSET, in fact, requires that one or more local structures be defined by the System Administrator, following the logic provided by the SSU Catalogue. It is therefore necessary for the authority to be registered in IPA. The SSU Catalogue, in fact, provides for the association of a procedure to an office of the authority, where an office is identifiable with the unique code present in IPA: a Consistent Organisational Area (A.O.O,) or an Organisational Unit (U.O.). In order to allow the above-mentioned offices to handle the proceedings under their jurisdiction, the Authority will have to define the same offices also in the SSET.
