SaaS EDI & e-Invoicing SaaS solutions: The only solution to integrate, comply and globally scale

To think of an international SaaS EDI or e-Invoicing project with a solution other than on-cloud is really not an option. It is a strategic nightmare. When compared to on-premise solutions, SaaS EDI platforms lead the way as the only viable option to respond to the demands, speed and compliance required by global supply chains and advanced regulatory frameworks. 

SaaS platforms are no longer an alternative. They are the only possible architecture that can guarantee a business can exchange, securely, with traceability, and non-stop, critical documents with its clients, providers, logistic operators, and tax authorities across multiple countries. They also allow tackling ERP-EDI integrations on the cloud with guarantees, a key requirement for end-to-end automation without friction between systems. 24x7 availability, constant updates and specialized technical support, the SaaS model provides the tools to tackle real company challenges any business may need to operate uninterrupted and comply with regulations that change from country to country as well as almost month to month.  

Insisting on proprietary infrastructure or legacy applications is not a strategic decision: it is a rejection towards progress. When your business depends on receiving an order, an invoice is valid, or a fiscal document complies 100% with the local regulation, the technology behind that cannot fail. The SaaS model is the only one designed for that. 

The intent of this article is not to persuade you. It rather begins with an understatement: if you are going to carry out EDI or E-invoicing today, you will do so on-cloud. On this article we will explain why, and what elements of a SaaS solution such as EDICOM’S stand out in environments where every document is critical. 

SaaS EDI and E-invoicing platforms or how to manage critical documents, complex regulations with zero margin for error

The volume, speed, and criticality with which companies exchange documents in 2025 bears no resemblance to how things were done just a few years ago. EDI and electronic invoicing are no longer optional or administrative tools. Today they are the backbone of global industrial, commercial, and logistics operations. This changes everything.

Because when a purchase order is not received on time, when an invoice does not comply with local regulation, or when a despatch advice never reaches the carrier… the supply chain breaks. And with it, money is lost, reputation disappears, and in some cases, so do clients. 

In this context, only one approach is viable: professional, automated, and built to scale without room for failure. And that requires recognizing a few truths.
 

What does an international EDI project require nowadays?

In 2025, an EDI project is no longer simply connecting two businesses. Now it implies integrating varying systems (ERPs, CRMs, WMS…), adaptation to the different standards (EDIFACT, X12, XML, UBL, etc.), comply with response times nearly in real-time and guarantee the traceability of each transaction. 

In addition, the multiple stakeholders involved (clients, providers, carriers, logistics operators, marketplaces, etc.) requires managing an enormous variety of formats, channels, communication protocols: AS2, SFTP, Web Services, API REST, Peppol, among others. 

In other words, the project becomes less technical and more strategic. The margin for error is reduced to zero.

What makes global e-Invoicing particularly complex?

Unlike other EDI flows, electronic invoicing has one additional layer: fiscal regulation.

Sending an invoice is no longer simply generating a PDF or sending an XML. It involves meeting the strict technical, legal, and procedural requirements that vary significantly from one country to another:

• Mandatory structural validations
• Digital signatures using valid certificates
• Prior or post-submission via governmental platforms
• Legally recognized e-archiving rules
• Integration with additional fiscal control mechanisms

All of these obligations are also under constant change. In some countries, non-compliance will mean incurring in administrative fines, or at best, an inability to invoice or collect payments. 
 

Why there is no longer room for ‘Custom-built’ Solutions

For years, many companies have tried to solve the puzzle with in-house developments, hybrid solutions or small patches adapted to their ERP. That is no longer viable. Each new country, each new partner, each regulatory change, becomes a technical and legal nightmare. 

The ‘in-house’ approach is not scalable, it does not guarantee compliance, and it cannot provide 24x7 support, which is exactly what global operations now demand. Custom solutions end up being expensive, slow, difficult to maintain and completely inefficient when put up against the complexity of today’s environment.

That’s why, if you’re serious about global EDI or e-Invoicing, the SaaS model is not an option. It is a necessity.

EDI as a Service: The technology that makes global EDI and e-Invoicing possible

In an international ecosystem where hundreds of thousands of documents are exchanged daily, EDI as a Service model has proven to be the most reliable for volume management, compliance, and traceability. This is technology built for continuous operation, limitless scalability, and effortless complexity management without burdening the client. A technology built for scenarios where failure is not an option. 
 

24x7 availability for critical operations

The SaaS model allows for keeping the platform operational at all times, in any place, with no local or external architectural dependencies. In industrial or logistical environments, where a purchase order or invoice activates an entire chain within the process, the availability of the service is not an extra: it becomes the heart of the operation. 

In the case of EDICOM, this translates to:

• Redundant data processing centers with synchronous replication
• Real-time monitoring
• 24x7 technical intervention by in-house experts
• A guaranteed contractual SLA of 99,9%
   

Automatic regulatory updates without client intervention

One of the great values of SaaS e-Invoicing are the updates which do not fall on the client. When regulation changes take place in Mexico, Italy, Poland, or Colombia, the platform is adapted on the back-end, without freezes, no additional developments, and no hidden costs. 

This allows to comply with requirements such as:

• New official XML Schemas
• Changes in the fiscal validation mechanisms
• Inclusion of new mandatory fields
• Rules concerning archiving or digital signature modifications

The SaaS platform not only keeps the solution alive. It keeps it compliant. 
 

Real scalability for large volumes and complex architectures

The exchange of documents is not linear. It has highs. It has campaigns. There are moments in which a company might 10x its business activity within days. A well-designed SaaS platform doesn’t just support it: it absorbs it without an impact to the user. 

From the capacity to process millions of messages per month, up to handling different country environments, client or partner, the SaaS model allows growth without friction, with no need to scale hardware or internal technical resources. 

Multi-country e-Invoicing compliance: the hidden challenge of electronic invoicing

In many countries, issuing an invoice is not only a technical or accounting question: it is a fiscal operation managed by the tax authority. This means that each invoice must comply with specific norms, which vary and change, yet are imposed by governments that, ever more often, require previous validation, an electronic signature, automatic delivery, or digital archiving with legal value. 

This is one of the most critical points many companies underestimate when tackling a multi-national electronic invoicing project:  the invoice is no longer issued for the client, but rather for the fiscal authority first. This drastically changes the entire process. 
 

More than 80 countries, more than 80 ways to invoice correctly

Each country defines its own e-Invoicing model: from technical formats, XML structures, response times, methods of validation, and even mandated delivery platforms. 

• In Italy, the invoice must go through the SdI (Sistema di Interscambio)
• In Mexico, through the SAT and the CFDI Schema
• In France, you can find a model containing public and private portals
• In Poland, KSeF will be mandated for all businesses

And this is just the beginning. What works for one country will not work for the next. And when you operate in 5, 10, or 20 countries at once, the complexity is multiplied with each new jurisdiction. 
 

e-Invoicing, CTC, Peppol, ViDA: an ecosystem in constant evolution

Electronic invoicing isn’t just regulated, it’s under constant transformation.

Each year new obligations are added, new control mechanisms or new validation systems:

• CTC (Continuous Transaction Controls): fiscal control, in near real-time before issuing the invoice.
• Peppol:  paneuropean network (more and more global) for the exchange of electronic documents in a structured format and over the so-called Peppol Access Points or accredited access nodes on the Peppol network. 
• ViDA (VAT in the Digital Age):  a new proposal from the European Commission to revolutionize the current model of intra community VAT.

Without a solution that can update itself automatically and dynamically adapt to all these regulatory changes, the risk of non-compliance is constant. 
 

The role of the SaaS provider in automating compliance

This is precisely where the SaaS model showcases its major benefits. 

A well-designed platform allows for regulatory changes to be implemented on the system without the client moving a finger. The service provider will be in charge of: 

• Bring forth new validation rules or document schemas
• Adjust connections with governmental agencies
• Implement new fiscal flows without interrupting daily operations
• Archive and sign according to the legal framework in place within each territory

This shouldn’t be an extra. This constitutes a basic condition on any SaaS EDI environment in order to continue operations without interruptions. And only a SaaS infrastructure managed by an experienced provider with international exposure can guarantee this level of compliance, country per country, document per document. 
 

One single platform to integrate systems, documents and regulations

A SaaS EDI platform has no real value if it cannot fully integrate with your technological environment and your critical document processing operations. Those companies operating at international heights don’t tend to use one single tool: they operate on different systems (ERP, CRM, SGA…), multiple locations, and multiple critical document handling processes. 

For this reason, an EDI and e-Invoicing solution cannot be an information silo. It must integrate seamlessly, reliably, and in an automated manner with your environment and systems, regardless of the landscape at hand. 
 

Native SAP connectors, Oracle, Microsoft Dynamics and more

A specialized provider must offer ready-to-go connectors for most ERP systems on the market. This will allow you to drastically reduce implementation times and minimize maintenance, creating a secure in and out flow of communication for both AR and AP flows. 

EDICOM, for instance, offers certified connectors for:

• SAP ECC and S/4HANA
• Oracle E-Business Suite and Oracle Cloud
• Microsoft Dynamics 365
• Proprietary systems or legacy applications via APIs or specific adaptors
   

Exchange of documents with clients, providers and authorities

More than an ERP, the SaaS platform must act as a central hub which guarantees the constant flow of documents between each of the stakeholders: clients, providers, logistics operators, or public administrations. 

This means:

• Supporting multiple formats (EDIFACT, X12, UBL, PDF, etc.)
• Different communication protocols (AS2, SFTP, Web Service, API REST, Peppol…)
• Syntactical validations and business rules being performed in near real-time
• Confirmation of receipt and total traceability markers on the document

In other words, anything that enters or leaves the system must be registered and validated, without manual intervention. 
 

Complementary modules: legal archiving, onboarding B2B, automatic validations

A complete platform will not be limited to issuing and receiving documents. It goes beyond, offering added services which optimizes processes and reduces the friction between partners: 

• Electronic archiving with legal validity:  In accordance with the archiving requirements set in place within each nation.
• Onboarding digital partners:  Web portal for providers and clients to fully integrate operations. 
• Automatic validations of data and business rules:  Error prevention or detection before they enter the ERP or final destination.

In this sense, the integration is not so much technical, but strategic. And it allows the platform to become a natural extension of the business, not another external application requiring upkeep resources. 
 

What you must demand from your SaaS EDI & e-Invoicing provider
 

When selecting a SaaS platform to handle delicate processes such as EDI or electronic invoicing, you are not simply purchasing an application: you are trusting that when everything else fails, this solution won’t. 

That’s why it’s not enough for a solution ‘to work’. You must demand tangible guarantees: of availability, of security, of compliance, and of customer support. Any provider that fails to showcase this with past cases, is simply not prepared. 
 

A 99,9% SLA, it’s own redundant data centers and 24x7 support

The provider must guarantee by contract a level of availability of at least 99,9%, and back it up with a solid technological architecture, not just with words. 

What you should demand as a bare minimum?

• Redundant data centers,  with real-time replication
• Active-active architecture to avoid isolated points of failure
• Independent technical teams, available 24x7 in different time zones
• Constant monitoring and proactive resolution of incidents

In essence: if your provider cannot guarantee your platform will not fall, you are working with the wrong provider. 
 

Certifications and audits that back its security

Handling fiscal and business documentation implies managing sensitive information. There is no room for error or uncalled for breaches of security. 

That is why trusted platforms certify their entire software under the most stringent security standards:

• ISO 27001:  Information Security
• ISAE 3402 / SSAE 18:  Auditing of internal control processes
• eIDAS and local certifications for digital signatures

These certificates are not a business ‘extra’. They are clear indicators that the service provider manages your data as rigorously as you manage your business. 
 

Developed Infrastructure and managed by the service provider

A critical platform cannot depend on third parties to operate. The provider must be the owner of its technology, of its source code, and the services as well as their evolution. 

• No software purchased by third parties
• No shared environments without real control
• No outsourced technical support without direct access to the system

When the provider is in full control of the technological stack, it can reply quickly, adapt to new legislation or technical challenges, and guarantee that there is no intermediary between your operations and its active status.
