Embracing digital transformation

Digital transformation is reshaping every aspect of business. Companies worldwide are navigating the transition from traditional to digital processes, seeking efficiency, accuracy, and sustainability. Among the many digital practices being adopted by finance departments, e-invoicing is becoming pivotal to modern business practices.   

This comprehensive e-invoicing guide dives into what it is, the benefits and challenges, the global landscape, and how businesses can seamlessly implement electronic invoicing in their digital operations.

Understanding electronic invoicing

What is e-invoicing and how does it work? 

Electronic invoicing, or e-invoicing, refers to the sending and receiving of invoices in a standardized electronic format, allowing direct processing by the recipient's ERP system without manual intervention. This automation speeds up transactions and minimizes errors that occur in manual processes. 

 

What is an e-invoice? 

According to the EU’s e-invoicing directive (2014/55/EU), an 'electronic invoice' is an invoice issued, transmitted, and received in a structured electronic format, such as XML or other structured data formats, which ERP systems can automatically process.  

Despite the name, the term 'e-invoice' is not limited to invoices – it also applies to credit notes and other documents. When asked to send an electronic invoice, sending a traditional invoice as a PDF via email is not sufficient. Below, we'll break down the differences between conventional invoices and e-invoices.   

The difference between traditional invoices and e-invoices 

 

Traditional invoices 

Traditional invoices require manual data entry, handling, and storage. These manual processes are prone to errors and inefficiencies. Traditional invoices have three integrated characteristics:  

  • Contain detailed data such as amounts, descriptions, and quantities  
  • Render data in a visual format on printed paper for manual reading  
  • Possess a physical form for manual handling and exchange  

Digital invoices, such as PDFs and digital images, are more efficient as they remove the aspect of physical handling. However, they still require manual viewing and data entry.  

 

Electronic invoices 

E-invoices eliminate the need for physical handling, reducing storage and processing inefficiencies. To qualify as an e-invoice, the document needs to be:   

  • Created with the correct structure 
  • Transferred from the seller’s system to the buyer’s system 

Electronic invoices don't primarily include a visual presentation of data, though they can be rendered visually for checks or transposed into visual formats. The aim is system-to-system communication, with the visual format being secondary. E-invoices are not: 

  • Unstructured invoice data in PDF or Word formats 
  • Images of invoices such as JPG or TIFF files 
  • Unstructured HTML invoices found on web pages or in emails 
  • OCR (scanned paper invoices) that still require manual data extraction 
  • Paper invoices transmitted digitally, such as via fax machines

B2B and B2G e-invoicing 

Electronic invoicing is versatile, allowing various types of transactions, including Business-to-Business (B2B) and Business-to-Government (B2G). Each type presents unique requirements and benefits:  


B2B electronic invoicing
B2B e-invoicing streamlines the exchange of invoices between companies, enhancing efficiency and reducing errors. Adopting this invoicing method in B2B relationships often leads to improved payment times and stronger supplier-buyer relationships.

B2G electronic invoicing
B2G e-invoicing involves transactions between businesses and government entities. Many governments worldwide are mandating this secure invoicing method for public procurement to enhance transparency, efficiency, and compliance. This requires businesses that deal with government contracts to adopt e-invoicing solutions compliant with specific government standards.

Common e-invoicing formats and standards 

In electronic invoicing, many formats and standards exist, each designed to facilitate seamless and standardized electronic data exchange between businesses. Understanding these formats ensures compatibility and compliance across different systems and regions. 

UBL:
Developed by OASIS, UBL (Universal Business Language) is one of the most widely adopted standards, designed to provide a generic XML-based framework that can be applied across various business transactions, including invoicing. 

EDIFACT:
EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport) is an international standard that defines a set of syntax rules for structuring data, widely used for cross-border transactions. 

ANSI X12:
ANSI X12 is a set of standards that define how documents should be structured and formatted for electronic exchange, covering a wide range of industries and transactions. 

Peppol:
Peppol (Pan-European Public Procurement Online) is a standard and a network that facilitates e-procurement and e-invoicing across Europe and beyond. It allows governments and businesses to exchange electronic documents over its network, using a standardized format.
