2. How does EDI work?
EDI processes follow clear rules: Business documents such as orders or invoices are extracted from a source system (e.g. ERP), converted into a standardized format and transmitted via a secure protocol. The recipient system processes the data automatically – without human involvement.
3. What are the common EDI standards and formats?
To ensure that sender and receiver speak the same language, EDI uses standardized digital formats for electronic exchange between companies and partners, so-called EDI-files. These use established standards.
Common EDI standards:
Depending on industry and region, multiple formats may be used in parallel.
What transmission protocols does EDI use?
Besides formats, the transmission method is key. Common protocols include:
- AS2: globally established, encrypted
- OFTP2: preferred in the automotive sector
- SFTP/FTPS: for file transfer
- REST/SOAP: modern API communication
The protocol choice depends on partner requirements, security needs and the degree of integration.
4. How is EDI used in practice?
EDI is a proven integration solution, adaptable to industry-specific needs. Document types, standards and protocols vary by sector – as does the required level of integration with partners and systems.
The automotive industry is one of the pioneers in EDI usage – especially due to tightly synchronized Just-in-Time and Just-in-Sequence supply chains. EDI is used here for a wide range of communication and logistics processes:
- Delivery schedules (e.g. VDA 4905)
- Shipping notices (e.g. VDA 4913, EDIFACT DESADV)
- Production data and status updates
- ASN (Advanced Shipping Notices)
- Integration with OEMs and Tier-1 suppliers via OFTP2
In both brick-and-mortar and online retail, EDI plays a key role in automating large order volumes and integrating with marketplaces, distributors and supply chain partners.
- Electronic orders (ORDERS)
- Order responses (ORDRSP)
- Shipping notifications (DESADV)
- Invoices (INVOIC)
- Product data and pricing updates (PRICAT)
Logistics service providers use EDI to exchange real-time data, digitize transport processes and provide tracking information across systems.
- Transport instructions (IFTMIN)
- Bills of lading (B/L)
- Track & Trace (IFTMCS)
- Loading lists, delivery confirmations
In the highly regulated healthcare sector, EDI ensures reliable and secure transmission of sensitive data – with a strong focus on compliance and industry-specific standards.
- edication orders
- Drug delivery notes
- Billing data for health insurers
- Traceability and serialization
SEEBURGER offers tailored EDI industry solutions based on extensive experience, specific standards and certified connectors.
5. EDI and API – differences and synergies
EDI (Electronic Data Interchange) and APIs (Application Programming Interfaces) are among the most important technologies in the field of system integration today. Both pursue the same goal: the secure and structured exchange of information between business partners. However, the way they work and their application logic differ fundamentally.
EDI – the standard for stable, automated processes
EDI is designed for the reliable transmission of structured documents such as orders, delivery notes or invoices in standardized formats (e.g. EDIFACT, ANSI X12). Typically, data is exchanged in batches at defined intervals, fully automated. EDI is particularly widespread in industries with high transaction volumes and regulated processes.
Key strengths of EDI:
- High level of automation
- Standardization through established formats
- Industry-specific compliance (e.g. VDA, Peppol)
- Scalable for large partner networks
API – the technology for real-time and flexibility
APIs allow real-time communication between systems. They are especially valuable when processes need to be triggered ad hoc, in response to events, or configured individually. APIs are based on REST or SOAP protocols and enable targeted, modular data exchange – for example for price queries, stock levels or status updates.
Key strengths of APIs:
- Real-time capabilities
- High flexibility and customization
- Easy integration with modern IT environments
- Particularly well suited for cloud-based services and platform ecosystems
Hybrid integration strategies: combining EDI and API
In practice, EDI and APIs are increasingly being used in combination – for example, when EDI processes are enhanced with APIs (e.g. for querying status updates), or when companies communicate across different levels of integration maturity.
Example scenario:
- Order placement via EDI
- Order status retrieval via API
- Invoice transmission via EDI
Both technologies have their justification – and their strengths. EDI stands for proven stability, APIs for dynamic real-time interaction.
Together, they form the backbone of modern digital ecosystems.
SEEBURGER supports hybrid architectures through native API Management integration into the BIS Platform.

9. What are the core components of an EDI solution?
A professional EDI solution typically consists of three tightly integrated technical modules. Together, they form a powerful interface between internal ERP systems and external business partners.
1. ERP connector
An ERP connector connects the internal ERP system to the EDI platform. Ensures seamless exchange of business documents in in-house formats and enables automated triggering of inbound and outbound processes.
Example: An invoice is created in the ERP system and automatically handed over to the converter.
2. EDI converter
An EDI convertertranslates in-house formats into standardized EDI formats – e.g. EDIFACT, ANSI X12 or XML – and vice versa. This ensures that all partners receive data in the agreed structure.
Example: An XML-based order is translated into an EDIFACT message.
3. EDI communication adapter
Ensures the technical delivery of EDI messages to business partners – using AS2, OFTP2, SFTP, or API depending on requirements. Incoming messages are processed in accordance with the protocol.
Example: A shipping notification is transmitted to an automotive supplier via OFTP2.
10. What EDI operating models are available?

12. What determines the success of an EDI project?
To successfully implement an EDI project in a company, three factors are crucial: full support from management, professional project management and a precise and clear definition of objectives.
Management support
A positive attitude on the part of management has a significant influence on the acceptance of the system by employees.
Management support is the most important success factor in the introduction of an EDI project. The entire management, across all affected departments, is required to clarify the meaning and purpose of the EDI implementation and to actively support it in all areas. Successful project management also includes good change management.
For example, the priority of the EDI project in the company is made clear to all employees from the outset by the introduction of classic controlling by higher-level departments. In addition, the targeted communication of progress to the various stakeholders in your company is of crucial importance.
Clearly defined reporting channels and management decision-makers make it easier for everyone involved to understand the project processes and find the right contacts.
Project management
Stringent project planning and control, clear assignment of tasks by the project management, high leadership qualities and close cooperation with the EDI solution provider are essential for a smooth project process.
The implementation project must be equipped with the necessary personnel resources for all phases of the implementation - from preparation to final acceptance and release of the solution. Professional qualifications are a basic requirement for all members of an EDI team and IT training for employees is the be-all and end-all for a successful software implementation.
In our SEEOcta blog series, we take a closer look at how to successfully manage a project.
This goes hand in hand with the necessary decision-making authority that is granted to those involved in the project. After all, short decision-making paths and sufficient time and personnel buffers make it possible to set up a schedule that is easy to adhere to and avoid deadline pressure.
Precise target definition
The project objective must contain a clear, complete and verifiable description of the target state to be achieved by the EDI integration project.
The exact definition of the EDI project objectives represents the benchmark for the achievement of objectives and enables the monitoring of compliance with objectives throughout the course of the project.
Such a precise definition of objectives gives you
- a secure basis for planning and action for the project manager.
- a starting point for the structure of the entire project planning.
- a fixation of the project completion.
A correctly formulated project objective should be achievable, realistic and complete. In addition, the goal must be well-founded in that it is free of contradictions and verifiable and leaves no room for interpretation. Possible solutions should not be excluded or predetermined from the outset when formulating the objective and it is important to always document everything.
Simply ask yourself the following questions when setting objectives:
- Why is an EDI solution being introduced? (cost aspects, transparency, compliance, etc.)
- What should be achieved with the EDI project? (e.g. increasing supplier satisfaction, speeding up process times, improving the company's image on the market)
- How deep should the integration be or how high should the degree of automation be?
- In which locations and countries should the EDI solution be operated?
13. What is the methology of an EDI project
The successful implementation of EDI requires thorough planning. Two preparatory steps lay the foundation for a strong project start:
1. The preliminary study – establishing a sound decision-making basis
The goal of the preliminary study is to assess, with minimal effort, where and how the introduction of EDI would be beneficial. It identifies:
- Existing systems and processes (current state)
- Potential for process optimization through EDI
- Interests and readiness of current business partners
- Timeframe, organizational and technological framework conditions
- Initial effort estimates for the project phases
- Financial assessment and ROI scenarios
Result: A finance-focused preliminary study report for executive management – serving as the basis for the final project decision.
2. Requirements and system selection
Based on the target concept, technical, organizational, and business requirements are derived – in preparation for a structured requirements specification (RFP).
Questions to clarify:
- Which operating model is appropriate – in-house, SaaS, or hybrid?
- What technical prerequisites must be met?
- Which partners need to be integrated?
Typische evaluation criteria:
- One-time implementation costs
- Ongoing operating, maintenance, and transaction costs
- Internal resources and required competencies
- Scalability and long-term viability of the solution
Tip: SEEBURGER supports you with structured requirement-gathering workshops.
14. How does the technical EDI implementation work?
The implementation of the EDI solution in your company is divided into three phases: the EDI concept phase, the EDI test phase and finally the go-live phase and live operation. This structured introduction ensures that your EDI solution is integrated seamlessly and efficiently.
EDI concept phase
The EDI concept phase takes place before installation in order to achieve an optimal solution. In this phase, standard EDI settings can be installed in a practical environment and the parameters tested accordingly.
As part of the concept phase, the EDI solution is
- Installation of the EDI solution on the test server,
- Basic installation and parameterization of the EDI solution,
- Checking and, if necessary, cleansing of master and transaction data,
- Possible adjustments to processes and interfaces,
- Fixing and documentation of the installation,
- Decision on going live with the EDI solution,
- Creation of test scenarios and test plans with corresponding reference data.
The EDI concept phase enables the project owners to understand the functions of the software and services holistically and at an early stage. This allows you to develop a comprehensive understanding of the EDI solution and its technical possibilities.
EDI test phase
In the EDI concept phase, test plans and reference data were defined, which are now tested intensively with the connected trading partners in the EDI test phase. In this phase, an iterative process is used to determine whether and which corrections need to be made to the process or the EDI solution. These test runs in turn result in changes to the definition and documentation of the overall system. This process finally ends with the acceptance of the system.
Going live and live operation
Once the test phase has been successfully completed, the EDI system switches from the test system to the productive system.
Project experience has shown that after two months of live operation, it makes sense to carry out additional downstream training for key users, administrators and end users. In this way, any unanswered questions and possible application problems can be resolved.
15. How does the migration from legacy systems succeed?
If existing EDI systems can no longer meet requirements for security, scalability, or flexibility, replacement becomes inevitable. SEEBURGER supports companies with a structured, secure EDI migration to a modern B2B/EDI integration platform – on-premises, hybrid or in the cloud.
The EDI migration takes place in five phases:
- Planning and Strategy Development
Define objectives, align stakeholders, evaluate risks, and establish project communication – this forms the foundation for a transparent and sustainable migration. - Analysis and Design of the Target Architecture
Assess current processes, data flows, and systems. Design a future-ready, cloud-enabled target architecture with a strong focus on integration, security, and compliance. - Migration Preparation and Data Evaluation
Develop migration and test plans, train teams, ensure data integrity and business continuity. - Implementation and Go-Live
Migrate data, configure processes, transition into the target environment and validate with test runs. - Post-Migration Support and Optimization
Stabilization, continuous monitoring, and optimization – ensuring your EDI system remains efficient and reliable in the long term.
