The Complete Guide to EDIFACT
EDIFACT: The Complete Guide to EDI Standards and Order Integration
Companies operating internationally must be able to reliably and securely exchange business documents, such as invoices, delivery notices, and purchase orders, with trading partners.
EDIFACT, formally known as UN/EDIFACT, is one of the most important standards behind that exchange. It provides businesses with a common electronic language, sending structured commercial and administrative data across independent computer systems.
Let’s explore what EDIFACT is, why it matters for companies, how it works and what are the common EDIFACT messages.
Key Takeaways
- EDIFACT is an international EDI standard that helps companies exchange structured business documents across countries, systems and trading partner networks.
- S2P goes beyond Procure-to-Pay (P2P) by including strategic sourcing, supplier management, and contract negotiation.
- EDIFACT order integration depends on accurate mapping, validation, and routing so order data is entered into ERP and back-end systems without manual rekeying.
- Many global businesses need to support both EDIFACT and ANSI X12, especially when operating across European, international and North American trading environments.
What Is the EDIFACT Standard?
The United Nations Electronic Data Interchange for Administration, Commerce, and Transport, or EDIFACT, is an international Electronic Data Interchange (EDI) standard developed under the United Nations framework and published by the United Nations Economic Commission for Europe (UNECE) to support the electronic exchange of structured data.
In practical terms, EDIFACT defines how business documents should be formatted so they can be processed automatically by different systems. Instead of sending a purchase order as an email attachment or a PDF that someone must re-enter, a buyer can send an EDIFACT ORDERS message directly from its procurement system. The supplier’s EDI or ERP environment can then read the message, validate the data and use it to create a sales order.
The standardization is why EDIFACT remains widely used in global trade. It helps trading partners exchange data consistently even when they use different ERP systems, warehouse platforms, transport systems, or finance applications.
Why EDIFACT Still Matters in Global EDI
Many modern integration projects involve technologies such as APIs, XML, and JSON. However, these have not replaced EDIFACT in many established B2B networks. Large retailers, manufacturers, logistics providers, and distributors often rely on EDIFACT because it is already embedded in their trading partner requirements and operational workflows.
EDIFACT is valuable for companies that need:
- Consistent document exchange with multiple trading partners
- Automated order, invoice, and shipment processing
- Lower manual data entry across supply chain workflows
- Standardized communication across countries and systems
The business value comes from what it enables: cleaner data movement, faster transaction processing, fewer manual touchpoints, and better partner connectivity.
How EDIFACT Order Integration Works
One of the most common integration needs is processing an EDIFACT purchase order, usually sent as an ORDERS message, into an ERP system. This is the intent behind the searches such as “integration EDIFACT order”. The user is not only trying to define the standard, but also to understand how an EDIFACT order becomes usable business data.
A typical EDIFACT ORDERS integration follows several steps
1. The buyer sends an ORDER message through an agreed communication method (for example, AS2, SFTP or a VAN).
2. The EDI platform receives the file and checks whether the message follows the agreed EDIFACT syntax and trading partner rules.
3. The data is mapped from EDIFACT segments into the fields required by the receiving ERP system (e.g., buyer details, ship-to location, or item numbers).
4. Once mapped, the order can be delivered into the ERP in the format that the system expects (e.g., API, XML, IDoc).
5. The ERP creates or updates the same order without a user manually rekeying the transaction.
Descartes EDI integration software
Descartes EDI integration software helps automate this process by receiving EDIFACT orders from trading partners, validating message structure, translating EDIFACT data into the format required by back-end systems, and routing the resulting transaction into ERP, warehouse, finance, or transportation applications.
Common EDIFACT Messages
EDIFACT includes many message types, each designed for a specific business transaction. The most common messages vary by industry, but several appear frequently across retail, manufacturing, logistics, and distribution. Common EDIFACT messages:
ORDER
ORDRSP
ORDCHG
INVOIC
DESADV
RECADV
REMADV
INVRPT
PRICAT
IFTMIN
Together, these messages allow companies to digitize a large part of the order-to-cash and procure-to-pay cycle. The strongest EDI programs do not treat each message as an isolated file; they connect messages into an end-to-end process where orders, confirmations, shipments, receipts, invoices, and payments can flow with fewer manual interventions.
What’s the Difference Between EDIFACT and ANSI X12?
EDIFACT and ANSI X12 are both standards, but they are most commonly associated with different markets and usage patterns.
EDIFACT is the international standard developed under the United Nations framework and is widely used outside North America, especially in Europe and cross-border trade. ANSI X12 is the dominant EDI standard in the United States and is widely used in North American retail, healthcare, logistics, finance, and manufacturing.
The two standards often support similar business processes, but they use different message structures and naming conventions. For example:
EDIFACT
ORDERS
INVOIC
ANSI X12
850 Purchase Order
810 Invoice
For international business, the key question is which standard their partners demand, not which EDI standard is better. Many companies require compatibility with both standards, making translation, validation, and routing particularly crucial.
EDIFACT may seem technical, but it has a significant impact on operations. Incorrect integration causes teams to spend more time on manual tasks, disrupting transaction flows between buyers and suppliers. EDIFACT solves this by linking processes and minimizing extra manual work.
Companies that benefit most from EDIFACT incorporate it into a broader strategy that connects trading partners, ensures operational continuity, and boosts team confidence in data movement within the supply chain.
A managed, scalable integrated EDI solution reduces risk by replacing numerous individual connections with a platform that standardizes connectivity, message translation, monitoring, and exception management.

"EDI can shorten the processing time for orders and invoices by up to 80%, while significantly reducing manual data-entry errors. Faster and more accurate information exchange helps both suppliers and retailers improve fulfilment, reduce costs and strengthen their relationship".

EDI FAQ
Companies can save time and costs by no longer having to retype data, thus avoiding errors. An optimal EDI connection will help improve customer service. Suppliers who use EDI have a stronger competitive position compared to peers who have not yet adopted EDI. Finally, the use of paper can be greatly reduced or even eliminated.
An EDI service provider is a service provider that sells the software and tools to exchange EDI, but also offers additional EDI services such as mapping or translation services to get messages into the right formats; or archiving of the messages. In addition, the EDI service provider also provides the platform or network on used to exchange EDI messages and will monitor the smooth exchange of messages 24/7.
The communication protocol is going to determine the way the connection is set up to exchange EDI messages. The most commonly used protocols are AS2, SFTP, HTTPS and APIs.
EDI solutions are available in different types depending on a company's EDI adoption rate. For companies that were not yet doing EDI and want to start with it, WebEDI is an ideal entry-level solution. Companies that exchange a lot of EDI are more likely to choose an integrated solution with their ERP, whether or not fully outsourced to an EDI service provider.
Many industries have their own standards, which were agreed upon and accepted internationally. For example, in retail and in healthcare the GS1 standard is used, in the automotive industry the standard is determined by ODETTE and in air cargo IATA.
Once you have determined the standard you will use, you need to check if your system can handle this standard. If not, you can use message mappings to ensure the standard will work with your internal systems.
EDI can be used in all industries. We see that in some industries the use of EDI has been given an extra boost by standardization organizations, for example GS1 in retail and IATA in the air industry. Sometimes companies will also require their suppliers to engage in EDI. In addition, there are quite a few government agencies such as customs and port authorities that require declarations to be sent electronically via EDI.
Industries where there is a high EDI adoption rate include retail, eCommerce, manufacturing and distribution, logistics, etc.
