Electronic invoicing and EDI in SaaS mode

Dematerialisation factures

In the enterprise software market, since the health crisis of 2020, SaaS has become the leading software usage mode. According to the annual report published by Numeum and Ernst & Young, over 75% of companies that have adopted paperless invoicing are already using SaaS solutions.

The future of business is digital. So, to ensure their digital transformation, infrastructure is at the heart of their concerns.


This raises a number of questions. Should you :

  • Subscribe to Cloud services ?
  • Have your own infrastructure and software ?
  • Opt for hybrid solutions ?


Ultimately, there are a number of criteria to consider when making your choice. These include internal resources, cost control and ease of deployment. But they also include data security, as well as the level of customization, scalability and flexibility to suit the company’s activity.


In this article, let’s find out why choosing a SaaS solution is ultimately the right choice for business-to-business exchanges, EDI and invoice dematerialization ?



What is a SaaS solution ?

SaaS or “Software as a Service” definition


SaaS, or “Software as a Service”, allows companies to subscribe to software remotely, rather than purchasing and installing it on their own hardware.


How does it work ?


Software and data are hosted in datacenters. First and foremost, users need an Internet connection to log on. Pricing can take the form of a monthly or annual subscription, and can depend on a number of metrics, such as :


  • Number of users,
  • Connection time,
  • Number of documents created. Example: the number of invoices issued for an invoice software, the number of EDI messages for an EDI solution, the number of transport orders for a TMS or the number of customs declarations for customs software, etc.


Software updates and maintenance are carried out by the service provider. These costs are included in the SaaS subscription.




It should be emphasized that when signing up with a SaaS provider, the company must first check two essential points : the level of SLA and the SaaS host’s commitments under the RGPD.


SLA level


The SLA or “Service Level Agreement” is the agreement between the SaaS provider and the company that expressly defines the level of service the company expects from the supplier.

It includes measurement parameters and penalties if the service level is not reached. Specifically, these include :


  • Service uptime,
  • Connection failure rates,
  • Response and resolution times for maintenance tickets,
  • Security : patch updates, attempted security breaches, etc.


SaaS service providers generally publish statistics on a portal to enable customers to check the SLA.


RGPD commitments


When choosing a SaaS solution, the company’s data is hosted by the service provider. It is therefore up to the company to ensure that the conditions of the RGDP are respected, particularly when personal data is involved :


  • Data and backups must be hosted in Europe,
  • The information provider must commit to data protection,
  • The hotline must be located in Europe.


To take things a step further, the CNIL has published recommendations for companies using cloud services.






SaaS software helps reduce companies’ digital carbon footprint


At a time when the digital sector is responsible for 3.7% of greenhouse gas emissions (according to the report by the Mission d’information sur l’empreinte environnementale du numérique), SaaS solutions and software enable companies to carry out their digital transformation while controlling their carbon footprint. Why is this so ?

Shared servers and optimized utilization


Above all, to :

  • Respond to peaks in activity,
  • Provide redundancy to ensure business continuity. Companies are oversizing their infrastructures. As a result, the utilization rate for servers owned by companies is 18%, compared with 65% for shared servers. It’s clear that SaaS services mean less investment in hardware and optimized utilization rates.

Renewable energy power supply


Data center operators, unlike enterprises, can easily negotiate with electricity suppliers to supply themselves exclusively with electricity generated from renewable energies.

As a result, they can reduce the carbon footprint of their datacenters. The GAFAs (Google, Apple, Facebook and Amazon) have their own sources of electricity, generated either by wind or solar power. Numerous solutions have already been deployed to recycle the heat generated by datacenters: district heating, the Val d’Europe aquatic center, etc.

Encouraging “flex office” and telecommuting


By being accessible from anywhere, at any time, SaaS software facilitates the transition to “flex office” in companies. Flex office” means not assigning a fixed workstation to an employee. This optimizes office occupancy and reduces lighting, air-conditioning and heating costs.

According to ADEME studies on the environmental impact of telecommuting, commuting distances are reduced by 65% and distances covered by 35%.

Reduced paper usage


And last but not least, SaaS software solutions are always accessible, whether in a meeting, on the move or at home, to consult or share a report or accounting statement, making printing unnecessary. A simple network connection is all you need to access a document or share notes.



Dematerialization in SaaS mode makes its mark on companies


EDI is the dematerialization of the administrative tasks involved in commercial exchanges, from order to invoice. Customer and supplier information systems exchange data directly via standardized electronic messages.

The dematerialization of invoices encompasses their electronic transmission and reception. These are referred to as issued invoices.


The company must always be in a position to take a new order, deliver and invoice within short deadlines and at known, controlled management costs. What’s more, the company must comply with all applicable regulations.


In conclusion, every invoice :

  • must be justified, with a reliable audit trail that can be traced back to the delivery and the order,
  • must comply with commercial and tax regulations,
  • must be electronic as of January 2026.






5 reasons to choose a SaaS solution for EDI and invoice dematerialization


Rapid deployment


SaaS solutions require no in-house hardware or software installation, and are immediately available to :

  • Set up mapping tables between ERP and EDI translator,
  • Test connections with EDI partners.


Cost control


When you sign up for a SaaS contract, you’ll know the annual cost of the solution, and how rates will change according to the volume of EDI messages and invoices transmitted and received.


Scalability and agility


SaaS solutions therefore enable :

  • Adapt to real business needs: number of active users, data volumes, number of transactions,
  • Accessibility from anywhere with an Internet connection, enabling teleworking.




The resources deployed for datacenter security are far more extensive than any single company can afford on its own. These include data back-up, infrastructure redundancy, protection against hacking attempts and data breaches, access control and more.


Regulatory compliance


Business and tax legislation and regulations change every year. SaaS software publishers and their service providers need to upgrade their software to comply with the law.
