DLTs can provide additional levels of security, accountability and others. Many authors support the co-existence of AIS and blockchain [27; 28; 29; 30]. However, there is not much literature on a specific application to justify this hypothesis. Furthermore, even though ERP vendors have started many blockchain projects (i.e., SAP Leonardo Blockchain) [31; 32], there is still limited theoretical applications. A novel (and significant) contribution is provided by analysing the case of e-procurement regarding blockchain applications and integration with AIS and ERP to fill this gap in the literature. E-procurement identifies how private companies and public administrations purchase goods and services from suppliers through the Internet [33; 34; 35; 36; 37; 38]. The term e-procurement means all systems that--thanks to a set of rules and procedures that include various types of software and information technology--allow the procurement of goods and services through the Internet. The e-procurement systems--used between companies (B2B commerce), between companies and individuals (B2C) or between companies and public institutions (G2B)--move online purchasing processes, drastically reducing the waste of time and resources typical of operations manuals [39]. The advantages of e-procurement are as follows: less waste, fewer costs, more efficiency. E-procurement promptly responded to the increasingly stringent demand for digitisation and innovation, structuring an online system to transparently manage tenders, awards and management control throughout the procurement phase. Thanks to the suppliers' register, in fact, the purchasing departments of private companies and public administrations now can better manage the award of goods, services or contracts. Furthermore, the integration of the e-Procurement platforms with the management systems of the purchasing companies, the so-called \"ERP\" or enterprise resource planning, is crucial, so that, in addition to optimal administrative management, everyone in the company can access in time real to availability or orders in process. In that sense, e-procurement is one of the most frequent and essential functions for enterprises, governments, and other organisations. When e-procurement platforms are effectively implemented, there are most efficient operations since the suppliers submit their application for registration with the online suppliers register and communicate directly on the platform [40; 41]. E-procurement promptly responded to the increasing demand for digitisation and innovation, structuring an online system to transparently manage tenders, awards and management control throughout the procurement phase [42; 43; 44]. Because of the suppliers' registers, the purchasing departments of private companies and public administrations can better manage the award of goods, services, or contracts. This paper finds support for blockchain applications in ERP and AIS. Furthermore, integrating the e-procurement platforms with the AIS and ERP systems of the purchasing companies can benefit better management, security, efficiency and productivity. Systems and operations can be accessed in time real to manage the availability or orders in the process [45; 46; 47] and increase efficiency. The e-procurement software platforms have been developed and can have many forms and provide much flexibility and associated benefits (cost control, various operations, etc.) for organisations [48; 49]. Finally, multi-user access allows the use of the platform simultaneously by buyers and suppliers, resulting in improved productivity. The verification of the identities is generally certified by a qualified digital signature system [50; 51] and other blockchain applications, and thus, it can enhance security and privacy.
