EDI (Electronic Data Interchange): Definition and important aspects for buyers
.jpeg)
EDI in a nutshell:
Electronic Data Interchange (EDI) is a standardized procedure for the electronic exchange of structured business documents between companies. For purchasing, EDI enables the automated, error-free and fast transmission of orders, delivery bills and invoices, which leads to considerable time and cost savings in the procurement process.
Example: By integrating EDI with 50 main suppliers, a car manufacturer reduces its process costs per order from 23 euros to 3.50 euros and shortens the lead time from order to invoice receipt from 5 days to 24 hours.

Introduction to EDI (Electronic Data Interchange)
What is EDI (Electronic Data Interchange)?
EDI, or Electronic Data Interchange, refers to the electronic exchange of business documents in a standardized format between business partners. Instead of sending paper documents such as orders, invoices or delivery bills manually, EDI enables the automated transfer of this information directly between companies' IT systems. This reduces errors, speeds up processes and improves the efficiency of business transactions.
Core elements of the EDI system
Importance of EDI in purchasing
In the procurement process, EDI enables efficient and error-free communication between buyers and suppliers. The rapid exchange of orders, order confirmations and invoices shortens throughput times and increases transparency. This leads to cost savings and improves business relationships with suppliers.

Implementation of EDI in the procurement process
By using EDI, business documents such as orders, invoices and shipping notifications can be exchanged automatically between the IT systems of buyers and suppliers. This eliminates manual data entry, reduces errors and speeds up communication processes considerably.
Practical example
Example: Automated ordering and delivery process between retailer and supplier
1st order creation: A retailer notices that the stock of an item (item number 1001) has fallen below the minimum stock level. His ERP system automatically generates a repeat order for 500 items.
2. EDI order transmission: The order is generated directly from the ERP system in EDIFACT format and sent to the supplier's ERP system via a secure EDI connection.
3. order confirmation: The supplier system receives the order, checks availability and delivery date and automatically sends back an electronic order confirmation.
4. dispatch and des patch advice: After picking and dispatch, the supplier creates an electronic despatch advice, which provides the retailer with precise information about the content and arrival time of the delivery.
5. goods receipt and invoicing: When the goods arrive, the retailer scans the delivered items and the system automatically compares the delivery with the shipping notification. The retailer then receives an electronic invoice, which is transferred directly to their system and used for payment processing.
This fully automated process minimizes manual intervention, increases data quality and significantly reduces the time required for order processing. Both retailers and suppliers benefit from more efficient processes and can use resources for value-adding activities.
