EDI software has done the same job for decades: moving business documents between trading partners without anyone retyping them. That job is still essential. What has changed is what happens next. Once an EDIFACT order lands in your ERP system, its data feeds planning, finance and customer service, and increasingly AI initiatives. If nobody can say what a field means, where it came from or who is allowed to use it, that data cannot be acted on safely.
SoftProject connects your EDI interfaces, governs the data they carry and turns it into automated action, on one converged platform instead of a stand-alone EDI converter.
What is EDI?
Electronic data interchange (EDI) is the computer-to-computer exchange of business documents in a standardized format. Instead of emailing a PDF invoice or typing a purchase order into a supplier portal, companies exchange structured messages that the receiving system can process without human intervention.
EDI brings together three elements: agreed message standards such as UN/EDIFACT, secure transport protocols such as AS2 or OFTP, and the processes that link each message to an internal system, usually ERP. The result is faster order-to-cash and procure-to-pay cycles, fewer data entry errors and a reliable record of every transaction between trading partners.
How does EDI work?
Every EDI message passes through three stages on its way out, and through the same three stages in reverse when it arrives.
Sending an EDI message
- Connectivity: your EDI system picks up the document from the source system, for example an order created in SAP.
- Conversion: the EDI mapping translates the internal format into the agreed standard, for example an EDIFACT ORDERS message.
- Communication: the message is transmitted to your trading partner over the agreed channel, such as AS2, OFTP or SFTP.
Receiving an EDI message
- Communication: the message arrives in the agreed standard and its receipt is acknowledged.
- Conversion: the message is translated into the recipient’s internal format.
- Connectivity: the data is posted to the recipient’s ERP or another target system.
Because no one rekeys data along the way, errors from manual processing disappear and both partners can automate entire transaction chains, from the first order to the final invoice.
EDI standards and message types
The most widely used EDI standard in Europe is UN/EDIFACT, complemented by industry subsets such as EANCOM, which GS1 developed for the consumer goods sector. Typical EDIFACT message types include:
- ORDERS (purchase order), ORDRSP (order response), DESADV (dispatch advice) and INVOIC (invoice) in manufacturing, wholesale and retail
- MSCONS (metered services consumption report) for market communication in the energy sector
- NOMINT, NOMRES, ALOCAT and SCHEDL for nominations, nomination responses, allocations and scheduling in the gas market
Alongside classic EDI, structured e-invoicing formats such as ZUGFeRD are gaining ground as B2B e-invoicing mandates take effect in Germany and France. That is one more reason to treat document exchange as a governed data flow rather than a simple file transfer.
EDI communication protocols
Message standards define what is exchanged; transport protocols define how. AS2 and OFTP are established for secure point-to-point exchange, SFTP and FTP for file-based transfers, web services for real-time integration and email for smaller partners. Digital signatures and encryption protect sensitive information in transit.
Why EDI data matters for enterprise AI
EDI is often treated as plumbing: as long as messages flow, nobody looks inside. Yet EDI flows carry exactly the data that AI initiatives depend on, namely what was ordered, shipped and invoiced, by whom and when. Before an AI agent can act on that data in production, four questions need clear answers:
- Meaning: what does each field mean, consistently across partners, message types and systems?
- Reliability: is the data complete, validated and of known quality?
- Governed access: which people and which agents may use which data, under which policy?
- Verifiability: can you prove what happened to a message from end to end, for auditors and under the EU AI Act?
A classic EDI converter answers none of these questions. A governed EDI platform answers all four, because mapping, monitoring, metadata and process automation share one foundation.
Choosing the right EDI solution
There are several ways to implement EDI: developing interfaces in-house, running them on an integration platform or outsourcing them to an EDI service provider. Each option can run on-premises, in the cloud or as browser-based WebEDI. The right choice depends less on company size than on your requirements and your existing systems. These questions help narrow it down:
- Which business processes should EDI support, and what should happen with the data afterwards?
- Do you need 24/7 availability and monitoring?
- Do you have the skills in-house to build and operate EDI interfaces?
- Which data may leave your network, and which regulations apply, such as GDPR or NIS2?
- How many trading partners, message types and processes need to be connected?
- In which countries and at which sites will EDI be used?
- What total cost of ownership is acceptable, including the effort of onboarding new partners?
On-premises and hybrid EDI software
For enterprises with many partners, high message volumes and their own IT team, on-premises or hybrid EDI software provides full control over data transfer and transactions within their own infrastructure. It reduces dependence on external providers and keeps sensitive data and the audit trail under your own governance. This is where data sovereignty requirements are easiest to meet.
Cloud EDI services
When internal resources are limited or new partner connections need to go live quickly, a cloud EDI service can help. It offers standardized interfaces, fast onboarding and flexible access, often in real time, with a lower upfront investment.
WebEDI for smaller partners
Smaller partners without their own EDI system can send and receive EDI messages through a web portal in their browser. This brings the long tail of your partner network into the same automated flow.
How to implement EDI in three phases
Successful EDI projects share three prerequisites: support from management, a detailed project plan and clearly defined, measurable goals. Defined reporting lines and decision-makers, close collaboration with your EDI provider and early training for the people who will run the solution make the rollout much smoother. Start with one high-value message flow, prove the result, then scale.
1. EDI concept phase
- Define scope, message types and the first trading partners.
- Validate parameters and master data such as customer and supplier records.
- Create test scenarios and check how the software behaves before installation.
2. EDI test phase
- Review test plans and reference data in depth with each connected trading partner.
- Iterate until mappings, acknowledgements and error handling work as expected.
3. Go-live and operation
- After successful testing, go live partner by partner.
- Monitor message flows, response times and errors from day one.
- Offer follow-up training so users can resolve issues quickly.
EDI integration on the SoftProject Platform
SoftProject brings EDI into one converged platform instead of adding yet another converter. Built on proven X4 technology, it covers the full path from partner message to governed action. Connect links partners and systems through EDI, ESB, ETL and APIs. Trust makes the data understandable and reliable with a data catalog, master data and quality controls. Act automates the processes, and the AI agents, that use it.
The platform runs on-premises, in the cloud or in a hybrid setup, and works alongside your existing systems. More than 200 prebuilt adapters connect ERP and business applications such as SAP, Oracle and Microsoft, so EDI extends what you already run instead of replacing it.
Configure your EDI infrastructure
X4 Designer is the central component for configuring and administering your EDI infrastructure. Here you set up the networks of participants that exchange messages, for example one customer with many suppliers, configure the message channel for each partner and define whether and how messages are processed before they are sent or after they are received.
EDI mapping without code
The integrated EDI mapping designer transforms any EDI data structure, including EDIFACT. You assign fields by drag and drop, with no programming required, and a preview shows the result while you build the transformation. Complex transformations can be implemented directly in the source view when needed.
EDI server: your message hub
X4 Server is the central point for processing and transmitting messages and for generating response messages. It supports all common communication methods, connects to databases to create new records and routes every processed message to a web portal or to X4 Control Center. Metadata is collected from every message and serves as a neutral communication log.
EDI monitoring and audit trail
X4 Control Center monitors every message you send and receive. Dashboards visualize values and metadata from the message history, and each dashboard or table view can be restricted to a specific user group. System administrators can focus on response times, transfer errors and message status, while management looks at accepted and rejected orders per supplier, processing times or open orders. The same history provides the evidence auditors ask for.
From EDI message to governed action
Because EDI runs on the same platform as data governance and process automation, the metadata of your EDI flows can be documented in the data catalog, linked to business definitions and traced through data lineage. Exceptions such as a rejected order or a price deviation can trigger automated workflows, and where you allow it, AI agents can work with EDI data through governed interfaces such as MCP.
EDI and APIs: complementary, not competing
APIs are often presented as the successor to EDI. In practice, most enterprises need both. EDI remains the standard for high-volume, contract-based B2B exchange with established trading partners, while APIs enable real-time integration with platforms, marketplaces and internal services. SoftProject handles both on the same platform, with shared governance and monitoring, so you do not have to run two separate integration stacks. Learn more about API management and about implementing an enterprise service bus.
EDI in practice across industries
SoftProject customers in many industries use the platform for electronic data and document exchange:
- Manufacturing and retail: ORDERS, ORDRSP, DESADV and INVOIC with suppliers and customers, including the EANCOM subset.
- Energy and utilities: market communication with MSCONS and gas-market messages such as NOMINT, NOMRES, ALOCAT and SCHEDL.
- Insurance: brokers connected as WebEDI partners through web apps built on the platform, such as a broker portal.
Across these scenarios, customers rely on digital signatures and encrypted documents to protect sensitive information, and on AS2, OFTP, SFTP, web services or email as the transport channel that suits each partner.

FAQs
What does EDI stand for in business?
EDI stands for electronic data interchange: the standardized, computer-to-computer exchange of business documents such as orders, dispatch advices and invoices between companies, without manual data entry.
What is an EDI file?
An EDI file contains one or more business documents in a structured standard format such as UN/EDIFACT. It is made up of segments and data elements that the receiving system reads automatically. An EDI mapping converts the file into the internal format of the target system.
What is EDI mapping?
EDI mapping defines how the fields of an internal document correspond to the fields of an EDI message, for example how an order in SAP becomes an EDIFACT ORDERS message. On the SoftProject Platform, mappings are built by drag and drop with a live preview, and complex transformations can be written in the source view.
What is the difference between EDI and API?
EDI exchanges standardized business documents with established trading partners under agreed standards and protocols. APIs provide on-demand, real-time access to data and functions. Most enterprises use both, and an integration platform lets them share the same governance and monitoring.
Which EDI standards and protocols does SoftProject support?
SoftProject supports UN/EDIFACT and subsets such as EANCOM, message types including ORDERS, ORDRSP, DESADV, INVOIC, MSCONS, NOMINT, NOMRES, ALOCAT and SCHEDL, e-invoicing formats such as ZUGFeRD, and transport via AS2, OFTP, SFTP, FTP, web services and email.
Can EDI software run on-premises?
Yes. The SoftProject Platform runs on-premises, in the cloud or in a hybrid setup. Running EDI on-premises keeps data and audit evidence inside your own infrastructure, which supports compliance with requirements such as GDPR and NIS2.
Is EDI still relevant in the age of AI?
More than ever. EDI flows carry structured, high-value transaction data. Once that data is defined, quality-checked, access-controlled and traceable, it becomes a reliable foundation for process automation and AI agents.
