E-Invoice Requirements: What Conditions Must Be Met?

The e-invoice responsibility includes not only the creation of the e-invoice, but also additional requirements that specify the features it must contain. To achieve these objectives, firms must consider a variety of factors:


The e-invoice must be in a standard format, such as ZUGFeRD or Factur-X, fully documented, and machine-readable. Factur-X represents an XML format that is applicable throughout the EU. The format is the standard for electronic invoicing, implementing Directive 2014/55/EU and so based on the European standard EN16931.


An electronic signature is required to verify the authenticity and integrity of the e-invoice. It is critical to ensure that the invoice is not altered during transmission and is sent by the authorized party.


To ensure a smooth flow, the e-invoice has to be transmitted to where the receiver specifies. It is, therefore, upon enterprises to take note of the recipient’s specific transmission requirements.


E-invoices must be preserved in such a way that they can stand up to an audit. Therefore, data saved ought to be non-changeable and time bound accessible.

What are B2B, B2C, and B2G e-invoices?


B2B (Business-to-Business) e-invoicing implies firms exchanging invoices via computers. In this case, sellers send electronic invoices based on goods or services supplied to other companies. This makes invoicing less complicated in terms of complexity, more accurate and reduces time it takes for one company to pay another.


B2C (Business-to-Consumer) E-invoicing represents invoice issuing electronically that occurs between one corporation and a single purchaser. Businesses send digital invoices for purchases which reduces its simplicity by decreasing paperwork while also offering the customers an online copy of these transactions.


When businesses engage with public sector institutions through invoicing electronically, it becomes known as B2G (business-to-government) e-invoicing. With this arrangement, businesses’ electronic invoices are transmitted to government agencies in accordance with established government standards and compliance requirements. By doing so, financial transactions involving the public become more efficient, transparent and accurate regarding their public sector.

What factors to consider when using e-invoicing?
