What is e-invoicing?

Panna Kemenes

As the world becomes ever more digitized, businesses are looking for ways to make payment and taxation less of a manual task. This often appears in the form of e-invoicing.

The EY - Worldwide electronic invoicing survey estimated that the total cost of processing an invoice manually is around $7. Processing an e-invoice - even when you include the cost of the software - comes in at around only 30 cents.¹

Businesses can save time and money when they move their payments and invoicing online. Even the US government has recognized that e-invoicing could save them over $100 million a year.²

So what are e-invoices, and what does it mean to use them? This article breaks down the benefits of moving your billing process online, and how you can get started.

What is an electronic invoice exactly?

What is e-invoicing exactly?

Let’s start with the definition. What is electronic invoicing? The e-invoice meaning is defined as “the interchange and storage of legally valid invoices in electronic format only between trading partners.”

So, what is e-invoicing? Characteristically, e-invoices don’t require the use of any paper, but are just as significant legally as paper invoices. They can prove compliance or even act as tax originals.

For an e-invoice to be valid, however, it must contain the correct data and it must be verifiably authentic. The invoice should be compliant, should clearly state the goods or services received, and be executable based on the invoice payment terms.

Typically it’s a good idea for both the buyer and the seller to hang on to e-invoices for a certain period of time - 3 tax years is advised in the United States. Invoices should be available to present to tax authorities if need be.

How did e-invoicing start?

How did e-invoicing start?

In its most basic form, the roots of e-invoicing can be traced back to the 1960s. At the time, companies were developing Electronic Data Interchange (EDI) systems to help transfer documents like invoices and purchase orders.

This early system laid the groundwork for the more digital version of the same concept that would emerge in the 1990s, when robust accounts payable software and web application became more prevalent.

By 2000, issuing invoices as CSV, PDF, and XML documents was fairly commonplace, and suppliers were enjoying a renewed ability to easily view, organize, and analyze their past sales.

As the digital era rolled in, companies began rapidly moving to e-invoicing. By 2012, 73% of businesses were using electronic invoicing to some extent.³

What are the benefits of e-invoicing?

What are the benefits of e-invoicing?

E-invoicing is a good idea for a lot of reasons, one of the most prominent of which is the ability to remove humans from most of the process.

Paper invoices must be manually entered into AP (accounts payable) systems - a process that takes time and is typically riddled with errors. On top of that, paper invoices are often moved from location to location, increasing the risk of them becoming lost, or their receipt or execution being delayed.

Other benefits include:

  • Increased ability to analyze spending

  • Faster payment cycles

  • Better ability to analyze contract performance

  • Enhanced tracking

  • Ease in dispute mitigation

  • Opportunity to find more supplier discounts and rebates

  • Overall better auditability

  • Ease of access to data

  • Green approach in reduction of paper use

E-invoicing for international transactions

E-invoicing for international transactions

One of the greatest benefits of e-invoicing is realized by companies that regularly deal internationally.

Invoicing electronically allows suppliers to interact more easily with their overseas clients, essentially eliminating the language barrier by using a uniform template structure that’s automatically recognized by e-invoicing systems.

It also means neither supplier nor customer is faced with mailing documents internationally - an expensive process that can take weeks or even months depending on where the documents need to go and the reliability of that region’s postal service.
