In the era of a pandemic COVID-19 many employees were forced to work remotely. On the one hand, taking into account highly developed digital technologies, performing work from home is not a major problem today. On the other hand, sending documents such as invoices electronically may raise some doubts, especially in terms of security.
Security of the electronic invoice system
Electronic invoicing is currently very popular, and due to the COVID-19 pandemic, it has become even more popular. They are subject to exactly the same legal standards as traditional invoices. The Polish legislator indicates, however, that this form can only be used if the recipient of the document agrees to it. Electronic invoices are usually sent by e-mail in PDF format. However, the safety of this solution raises some doubts. Under the law, the key to invoices is the authenticity that confirms their origin, integrity and legibility. Moreover, both the taxpayer and the contractor should be able to view the life cycle of each invoice, both current and archival.
Technology-based solutions can help to ensure a high degree of security for electronic invoices blockchain, ensuring their integrity. Thanks to them, each change is recorded in a distributed register, thus ensuring the possibility of verifying the life cycle of the invoice. Moreover, blockchain helps to maintain the integrity of the data contained in the document.
In the case of electronic invoices, each change made to them is recorded in the register, which is to deter anyone from interfering with the document. Thanks to modern management systems, it is possible to combine specific documents related to the data contained in the invoice. It is a great help during possible inspections. Currently, electronic invoices are not only more transparent, but also easier to settle, and, importantly, they are included in legal regulations.
VAT invoices on blockchain
Another important factor for the security of electronic documents is a properly secured cryptographic system, which may prove to be particularly helpful when recognizing the so-called "Blank invoices". Links to relevant documents may prove to be highly effective in preventing VAT fraud. The use of blockchain technology in electronic invoice systems can significantly affect the level of security. The introduction of appropriate data results in a simplified procedure for showing the emergence of a tax liability, which is of great importance for the process of document flow control. The legislator does not impose what technology is to be used to store electronic invoices. However, the most effective and functional system seems to be currently a system based on appropriate logical paths, carried out automatically for individual documents. It was a great convenience for both entrepreneurs and supervisory authorities.
