Electronic data interchange allows businesses to automate the exchange of important documents between their internal systems and those of external partners. Many standard document types have been defined for common transactions over the years. Some of the main EDI documents are purchase orders, invoices, shipping notices, product catalogues and more. This blog will discuss these documents and other concepts associated with EDI Solutions in detail.
Importance of EDI in modern business operations
EDI (Electronic Data Interchange) is an important technology for modern businesses, especially those operating in supply chains. EDI solution providers help with the electronic exchange of business documents like invoices, purchase orders, shipping notices and payment information between businesses.
It allows organizations to automate manual, paper-based workflows and improve the speed, accuracy and efficiency of exchanging business documents electronically. EDI reduces processing time, lowers administrative costs and minimizes errors associated with manual data entry.
For businesses that transact high volumes of documents with suppliers, distributors, logistics providers and customers, EDI can streamline operations and improve responsiveness. It helps integrate business processes across the supply chain in near real-time. EDI also enables integrated business solutions like e-procurement, supply chain visibility and optimized inventory management. These solutions rely on the automated exchange of information enabled by EDI service providers in the USA.
Benefits of EDI
Here are some of the benefits that can be achieved by businesses through EDI-
EDI Services reduces the time taken for exchanging business documents between organizations. Data is transmitted electronically instead of manually via post, courier or fax. This speeds up the processing of transactions and improves responsiveness.
EDI lowers costs in several ways. It cuts expenses associated with printing, mailing and storing paper documents. Automated workflows also require fewer employees for data entry and processing. Overall administration costs reduce considerably with the help of EDI service providers in USA.
EDI Services by EDI solution providers eliminate manual errors that commonly creep in while transacting documents. Data is transferred directly from one system to another electronically. This significantly improves the accuracy of transmitted information.
With EDI, data is exchanged in real-time between connected systems. This gives organizations up-to-date access to key business information for better decision-making and coordination.
EDI enables greater visibility into the status of transactions and operations through the supply chain. Timely exchange of accurate information provides a single version of the truth across parties.
EDI improves control over business processes with automated workflows, reduced manual intervention and standardized electronic document formats. This results in greater transparency and traceability if services of EDI experts are taken.
Common EDI Standards
Several EDI standards exist for electronic data interchange between businesses. The most commonly used standards by electronic data interchange consultants are:
ANSI X12: This is a popular EDI standard developed and maintained by ASC X12, a committee of the American National Standards Institute (ANSI). It defines formats for transaction sets like invoices, purchase orders, shipping notices and so on. Most organizations in the U.S. use ANSI X12 for EDI.
EDIFACT: Developed by the United Nations, EDIFACT is an international standard for EDI. It specifies message formats for a wide range of business documents and is used globally. EDIFACT supports multiple languages and currencies.
XML: XML has emerged as a widespread format for data exchange between businesses, including EDI. The EDI solution providers help define custom tags to structure and label data within documents. XML offers flexibility and is human-readable.
Both proprietary and industry-specific EDI standards also exist. These are often based on the major formats mentioned above. Businesses choose a standard based on factors like:
- Compatibility with trading partners
- Coverage of required document types
- Cost and complexity of implementation
- Flexibility and longevity of the standard
Moreover, most organizations adopt one standardized EDI format for all their business partners. Subsequently, they map their internal data to that standard format to enable the seamless transmission of documents electronically.
Essential Components of EDI Documents
EDI documents transmitted between businesses typically contain several key components to ensure accuracy and integrity. The main elements are:
- Transaction ID: A unique identifier is assigned to each electronic document for traceability. It helps link related transactions between trading partners if done properly by an electronic data interchange consultant.
- Transaction Set ID: Each type of EDI document (like an invoice or purchase order) has a standard identification code. This ensures uniformity in document formats.
- Sender and Receiver IDs: The identifiers of the sending and receiving parties are specified to accurately route documents.
- Date/Time Stamps: Dates and timestamps note when documents are created, sent and received for audit trails.
- Line-Item Details: Line items contain information about individual goods or EDI support services in transaction documents. They include attributes like product code, quantity, unit price and tax.
- Totals: The total amount, tax amount and any other summary financial information is captured at the document level.
- Acknowledgements: Receipts of EDI documents are automatically acknowledged to reduce errors from missing information. This can be a very helpful tool for an electronic data interchange consultant.
- Signatures: Digital signatures can be applied by EDI service providers in USA to transmit EDI documents to ensure integrity and non-repudiation.
- Error Handling: EDI standards define codes and features for reporting errors in transmitted documents and requesting retransmission.
Overall, EDI documents incorporate the necessary identifier, header, line item, and financial and audit information to automate their processing by internal systems. The inclusion of timestamps, acknowledgements, signatures and error-handling features ensures data integrity and traceability.
The Complete List of EDI Documents
Many standard types of electronic documents are defined for data interchange between businesses using EDI. The documents developed by EDI solution providers cover a wide range of common transactions within supply chains. Some of the main EDI document types are:
Purchase Order (PO)
The purchase order is one of the most common EDI documents, representing a buyer’s request to a supplier to provide goods or services. A standard EDI PO contains:
- Transaction set ID – identifies the document as a purchase order
- Header information – includes sender, receiver, reference numbers, shipping instructions, and terms and conditions
- Line-item details – specifies each ordered item with attributes like product code, quantity, unit price, description, preferred delivery date
- Totals – includes subtotals, shipping charges, taxes and the total amount of the order
- Special instructions by EDI Software Providers – any additional notes related to the purchase order
When a buyer sends a PO to a supplier via EDI, the automated workflow triggers the supplier’s order fulfilment system. The supplier then generates an Advanced Ship Notice (ASN) or invoice for transmission back to the buyer once the order is ready for delivery or payment. In this way, the PO acts as the starting point for an electronic transaction between a buyer and supplier.
Advance Ship Notice (ASN)
The advance ship notice is an EDI document sent by a supplier to a buyer informing them that an order is ready to ship. A standard ASN used by electronic data interchange companies contains:
- Transaction set ID – identifies the document as an advance ship notice
- Header information – includes sender, receiver, purchase order number being fulfilled and shipment details
- Line-item details – specifies each item in the shipment with product code, the quantity being shipped, requested delivery date and line number from purchase order
- Packaging information – includes the number of packages, their types and weights
- Carrier details – identify carrier name, pro number, truck and driver details for pickup
- Tracking number – shipment tracking number provided by the carrier
- Special instructions – any additional notes regarding the shipment
When a supplier generates an ASN in response to a purchase order, the buyer’s system automatically updates inventory records and schedules logistics. The ASN acts as an early notification that inventory is on the way, enabling buyers to plan for receiving and inspecting shipments. ASNs developed with the help of EDI software providers help optimize supply chain visibility and efficiency between buyers and suppliers.
When a supplier transmits an invoice electronically to a buyer via EDI, it triggers the buyer’s accounts payable system to generate a payment, reducing processing time and errors compared to paper invoices. EDI invoices enable benefits like faster processing, lower administrative costs, increased accuracy and real-time visibility into payments due.
Payment Remittance Advice
Payment remittance advice documents developed by electronic data interchange companies provide information about payments that have been made. It contains the transaction set ID identifying it, header information with payer and payee details, and individual remittance information for each applied invoice. It includes invoice number, amount paid and balance due, and total amount paid and helps reconcile payments made to invoices.
Purchase Order Acknowledgment
POA of electronic data interchange companies confirms a supplier’s receipt of a purchase order and intent to fulfil it. It contains the transaction set ID, header information with the sender, receiver and PO number details, line items specifics matching the PO, requested changes or exceptions, confirmation codes and signature. It acts as an electronic order confirmation.
A shipping notice informs a buyer that items have shipped. It contains transaction set ID, header information with sender, receiver and shipment details, tracking number, individual line items specifications, packaging info and carrier details. It provides early shipment visibility.
Product Activity Data:
PAD documents contain product information updates. They include transaction set ID, header with sender and receiver, product codes and specifications, changes to attributes, effective and expiration dates and reason codes. PADs ensure trading partners have current product data.
An inventory inquiry transaction requests current inventory information from a trading partner for specific products. The EDI software providers respond with inventory advice containing stock details like on-hand quantities, allocated quantities (reserved for orders) and available quantities (what remains after allocations). This enables businesses to check supply before placing orders, optimize replenishment processes and avoid stock-outs.
A 997 transaction is sent in response to every EDI document received. It communicates whether the received transaction was successfully processed, contained errors or failed. The 997 contains status codes indicating acceptance, rejection or warning along with detailed error codes. This functional acknowledgement notifies the sender of the outcome and the next steps to resolve any issues. It ensures complete and error-free data exchange.
An 824 document provides more details about errors or issues with a previously transmitted EDI transaction. It contains the identification of the original transaction, specific codes indicating the nature of the error or reject reason, and suggestions to repair the problem and resubmit successfully. Businesses use application advice documents to troubleshoot and correct errors in their EDI communications, ensuring conformance to standards and specifications.
Customs declarations electronically submitted via EDI contain crucial details about shipments entering a country for customs processing. They include product codes, quantities and value, tariff classifications, country of origin, names of importers/exporters and more. Transmitting customs documents electronically automates data capturing, speeds the clearance of cargo through customs inspection and reduces processing fees. Overall, EDI improves efficiency at borders for international trade.
Transportation documents like bills of lading issued electronically via EDI contain details about shipped goods, their packaging, pick-up and delivery addresses, names of carriers, consignors, consignees and transport conditions. EDI transmission through EDI software providers automates the generation, approval and routing of documents, potentially in real-time as goods are moving. This simplifies the management of shipping documents, supports tracking shipments electronically and helps resolve claims faster.
Electronic product catalogues containing comprehensive descriptions, images, weights, dimensions, features and specifications of a company’s offerings. When transmitted via EDI, trading partners can access up-to-date product information to browse, check availability and place orders efficiently. EDI-enabled product catalogues facilitate B2B eCommerce by ensuring accurate, consistent product data across the supply chain.
Credit and debit memos document value adjustments to previously issued invoices developed by electronic data interchange providers due to product returns, order cancellations or other reasons. They reference the original invoice number, specify details of the adjustment amount and calculate the revised balance due. When transmitted electronically via EDI, credit/debit memos enable automated corrections to payments, reconciliation of accounts and faster resolution of billing disputes between businesses.
Industry-specific EDI Documents
Beyond the generic suite of EDI documents commonly used across industries, certain sectors have additional transaction sets tailored to their specific needs.
In retail, documents like Purchase Order Change Requests, Chargeback Requests and Deduction advice deal with order amendments, product returns and chargebacks. Catalogue Updates communicate changes to product information. Trade Promotion Orders enable managing promotions and allowances.
In healthcare, EDI supports claims submissions, payments and remittance advice between payers and providers. EDI transactions include electronic HCFA 1500 and UB 92 claims, verification requests, claims status inquiries and payment summaries. EDI streamlines revenue cycle management.
In automotive, EDI documents cover orders, shipping notices, releases, invoices, forecasts and product data. They facilitate just-in-time manufacturing and lean production. Part Order Reports notify suppliers of part demands calculated from vehicle production schedules.
In financial services, EDI supports Straight-Through Processing and seamless integration between systems. Fund transfer notifications, account statements, remittance advice and settlement instructions are exchanged electronically between businesses and financial institutions.
For government contractors, EDI messages cover proposals, contracts, orders, shipping notices, invoices and receipts. Contractors transmit Detailed Cost Submissions while governments issue Requests for Proposals and Contract Definitization Notices. EDI aids compliance and speeds payments.
In summary, inter-business EDI extends beyond basic transaction sets to address industry-specific needs around claims management, supply chain coordination, compliance and regulatory reporting. Custom or extended document types are developed based on existing EDI standards but tailored to the functions, processes and information requirements of individual sectors. As a result , this helps electronic data interchange providers automate manual workflows and integrate external partners specific to their domain, improving efficiency and competitiveness.
