What is electronic invoicing or e-invoicing?

Electronic invoicing involves digitalizing the invoicing process, replacing traditional paper-based methods with electronic formats. This transformation streamlines the creation, submission, and processing of invoices, departing from conventional approaches’ manual and time-consuming nature.

Differentiating between traditional and electronic invoicing

The key distinction lies in the medium through which invoices are exchanged. In traditional invoicing, the reliance on paper documents often leads to time-consuming manual processes, making the entire system susceptible to errors and delays. Moreover, this method is prone to increased environmental impact.  

On the contrary, e-invoicing leverages digital platforms, enabling businesses to send and receive invoices quicker and more accurately. This expedites the invoicing cycle and minimizes the likelihood of errors, fostering a more streamlined and reliable financial workflow.

What can’t be considered an e-invoice?

It’s crucial to dispel misconceptions about e-invoicing. E-invoices are not simply scanned versions of paper invoices; they go beyond mere digitization. True electronic invoicing involves creating, transmitting, and processing invoices in a structured digital format. Unlike their paper counterparts, e-invoices are machine-readable, allowing for automated processing and integration with other digital systems.

Here’s a quick overview of the most common types of invoices that are not considered e-invoices and how they compare:

  • Unstructured invoice data issued in PDF or Word formats.
  • Images of invoices such as jpg or tiff.
  • Unstructured HTML invoices on a web page or in an email.
  • OCR (Scanned paper invoices).
  • Paper invoices are sent as images via fax machines.

Invoicing evolution: A historical overview of e-invoicing

The origins of e-invoicing trace back to the late 20th century, a period marked by the rapid integration of computers and digital technologies into business processes. Initial experiments with electronic invoices date back to the early 1990s, as companies began seeking alternatives to traditional paper-based methods. However, the true adoption of e-invoicing can be pinpointed to the early 2000s, when digital technologies became more accessible and widespread.

Pioneering pilot projects for e-invoicing found success in the Scandinavian countries, where the business community was open to innovation. 2004, for instance, Denmark emerged as a trailblazer by launching an electronic invoicing system for businesses. This experience inspired other nations and businesses, sparking a global shift toward embracing digital invoicing solutions.

In 2022, the countries that implemented mandatory invoicing included Egypt, France, Greece, India, Ireland, Italy, Jordan, the Netherlands, Norway, Poland, Portugal, Saudi Arabia, Spain, the United Kingdom, and Vietnam. 

The goals behind the inception of e-invoicing were manifold. Businesses aimed to streamline their invoicing processes, reduce the costs associated with manual paperwork, and enhance overall operational efficiency. Additionally, environmental considerations played a role, as the digitalization of invoices contributed to reducing paper consumption, aligning with sustainability initiatives. As the technology matured, E-Invoicing evolved from an experimental concept to a mainstream practice, reshaping the landscape of financial transactions across industries.

How does e-invoicing work?

Digitalizing workflows in both customer and supplier invoicing is a key feature of e-invoicing, contributing to the streamlined management of Accounts Payable (AP) and Accounts Receivable (AR). This electronic invoicing method enhances the efficiency of financial operations by providing a systematic approach to the processing and handling of invoices.
