By Roberta SalzanoUpdated: May 27, 2020, first publication: June 2019

The possibility to create a sales invoice online is at the heart of the dematerialization challenges for all businesses. The paper invoice is disappearing and being replaced by the electronic invoice, which offers many benefits to companies: time and financial savings, speed of processing and an eco-friendly approach.

However, these benefits come with conditions: companies must comply with legal aspects, have an archive, use an electronic signature and the EDI format to certify the issuer's authentication.

Lucky for you, dematerialization software allow you to issue online invoices and take care of these requirements. Which ones? appvizer provides you with all the answers in this article.

Is it really the right moment to change?

  • 80% of CEOs are investing in digital transformation
  • 95% of digital strategies are focused on software adoption
  • Technology and digitization matter to customers 


Characteristics and Definition of an E-Invoice in 3 Points

Online invoice: key features to keep in mind

Type of dematerialization
  • Unstructured electronic invoice (example: PDF format template)
  • Structured electronic invoice (example: EDI format)

Legal obligations in EU

  • Electronic signature or EDI format (authentication)
  • Electronic archiving of invoice
  • Financial management
  • Time-saving
  • Efficiency
  • Easy to control
  • Eco-friendly
  • Interoperable with other systems,
  • Providing a secure connection (e.g.: SSL encryption)

#1: The Different Typologies of a Dematerialized Invoice

Unstructured electronic invoice

  • is edited in non-alterable electronic formats such as PDF
  • is not editable in Microsoft Word or Excel timesheets (these formats are not certifiable)
  • is meant to be more accessible for small businesses
  • is cheap for small volumes of invoices

This unstructured paperless format suits perfectly small businesses’ needs: a software adapted to this type of structure allows the manager to save time and money on many of his tasks.

In the case of simple invoicing, where invoices are sent and received by email, the paper invoice remains the only legal proof; however, the commercial proof remains indisputable between buyer and seller.

Structured electronic invoice

  • complies to transparency requirements for tax administration
  • fit in the standards for electronic data interchange
  • is edited in electronic formats such as EDI
  • is essential to manage a large volume of invoices

This structured dematerialization format allows a quick search in archives through different filters (VAT, customer, period, etc.): thanks to the appropriate software that process can be shortened.

#2: 3 Legal Criteria Define the Electronic Invoice

For what concern American legal criteria it’s important to remark that providing a general framework is complex due to the complexity of the environment.

Criterion 1: The electronic signature as a guaranty of integrity

A third party authority applies its electronic certification to authenticate the issuer of the invoice, the client and the content of invoices.
It signs each invoice electronically (processing possible by lot).
The electronic signature allows the client to verify the authenticity of the invoice and the veracity of the information in it before the payment.

💡 Dedicated software, such as Yousign, ensure that businesses can dematerialize their invoices and sign them securely.

Criterion 2: The EDI format as an alternative to electronic signature

The EDI format (Electronic Data Interchange) is a standardized format for data exchange; standards are certified by authorities.

Invoices are processed automatically by computers in compliance with EDI standards.

When two companies choose this processing method for e-bills, they must first define a common exchange standard for teletransmission.

Criterion 3: Electronic archiving, retention obligation

When a structure sets up a tax dematerialization system, it must then store its electronic invoices in an archive which complies with the laws, an electronic safe guaranteeing the storage of e-bills in complete integrity.

#3: The 8 Advantages of Electronic Invoicing

Some software packages ensure secure invoice dematerialization: they make easier not only the control of invoices and payments but also of bank reconciliation, thus facilitating synchronization with the company's business account.

Here are the 8 advantages of using an online invoice system:

Advantage n°1: less paper, less direct costs

The absence of paper (or anyway a strong reduction of consume) eliminates many costs:

  • processing invoices,
  • printing,
  • ink,
  • stamps and envelopes used to send an invoice to the client,
  • the costs associated with archiving issues (paper, physical storage space, etc.).

Advantage n°2: accelerated processing

Postal and electronic processing are incomparable: the transmission of invoices digitally leads to the automation of certain tasks in invoicing, accounting and online payments.

Advantage n°3: saving of time and increase of productivity

By eliminating information delivery times, electronic invoice transmission boosts processing speed and employees’ productivity:

  • blank invoice template and contact details for recurring invoices
  • automation of bookkeeping reports
  • electronic signature or transmission in EDI format eliminates time-consuming human intervention
  • archiving and collection are done with a few clicks.

Advantage n°4: traceability and better control

Each document which complies with dematerialization standards is easily identifiable with the identification invoice number. As it is registered, the control of the tax administration becomes a simple formality.

Advantage n°5: increased efficiency

The dematerialization of invoices between customers and suppliers makes possible to manage incoming and outgoing flows, using software and an electronic safe available 24/7. The payment system will be facilitated through payment gateway, Paypal integrations, bank transfers and a lot of other tools to pay online and get or send the amount due.

Advantage n°6: fewer errors and disputes

Software solutions do not make calculation errors: you configure your tool and avoid the risk of errors due to double counting of information. Certifications guarantee the veracity of data.

Advantage n°7: a level of safety and reliability never achieved before

Three strong points reassure companies:

  1. The electronic signature or the EDI system guarantee the integrity of the invoice.
  2. Invoice dematerialization software allow for monitoring and systematic controlling procedures.
  3. A compliant electronic safe secures the storage of data in the cloud.

Advantage n°8: financial gains

Replacing paper results in a considerable reduction in direct costs, faster processing, and shorter lead times by increasing productivity: the financial repercussion results in real savings, but also in a more competitive return in the long term.
