Electronic Data Interchange or EDI software enables two or more businesses to exchange data securely in agreed formats, even if they use different ERP systems and applications.
Critical data such as purchase orders and invoices are moved between trading partners electronically, avoiding manual intervention such as document re-keying and data entry errors. Document exchange under a manual system can take days, versus minutes when sent via electronic data interchange software. The security provided by EDI software is another major benefit.
Let’s compare document exchanges between trading partners using paper versus EDI.
Paper Based
- The Retailer raises a Purchase Order (PO) in their ERP system
- The PO is either emailed, faxed or mailed to the Supplier.
- The Supplier receives the PO and manually enters it into their sales order system
- If goods are out of stock, the Supplier calls or emails the Retailer to discuss the options available.
- The Retailer and Supplier update their ERP systems accordingly for the new quantities and or prices.
- The Supplier prints an invoice and encloses it with the shipment and/or sends it separately by email, fax or mail to the Retailer
- The Retailer manually enters the invoice into the Accounts Payable system after manually reconciling the invoice to the order.
- If errors appear on the invoice compared to the PO, the Retailer’s Accounts Payable Department calls the Supplier to get the error corrected, delaying payment to the Supplier.
- The exchange of paper documents can often take a week to process. If there are errors caused by manual data entry, the time can be greatly increased.


EDI (electronic data interchange) Process
- The Retailer’s procurement system automatically generates a PO when inventory reaches the re-order level
- The Retailer’s ERP system sends the electronic PO file to EDIStech via a secure EDI internet connection. This is for non-cloud based ERP systems. For Cloud based ERP systems, EDIStech retrieves the PO via an API.
- EDIStech’s EDI software translates and validates the data before sending the PO to the Supplier’s ERP system via a secure internet connection or via an API connection.
- Within minutes the sales order system uploads the PO file which is now in the file format that the Supplier’s ERP system accepts.
- The Supplier sends a Purchase Order Response (POR) to EDIStech, who translates this file and sends the file to the Retailer. The POR instantly advises the Retailer on what goods can be supplied.
- The Retailer uploads this POR into their system as it is in the correct format. The Retailer’s warehouse is now fully aware of what stock will arrive.
- The Supplier creates an invoice and sends this file to EDIStech.
- EDIStech’s EDI system validates the data on the invoice to the Retailer PO and translates the invoice file into the format the Retailer can accept.
- EDIStech’s EDI software sends the invoice to the Retailer who passes the invoice for payment as it is fully reconciled.
- The EDI data transfer can be completed within minutes.

EDI IN A NUTSHELL
In summary, EDI solutions provide businesses with the opportunity to reduce or eliminate manual data entry errors, such as shipping and billing errors. EDI eliminates the need to re-key documents on the destination side. One very important advantage of EDI over paper documents is the speed in which the trading partner receives and incorporates the information into their system thus greatly reducing cycle times. For this reason, EDI is a critical component of just-in-time production systems.
