Order-to-Cash (O2C) Process with EDI X12 Transactions

The EDI Order-to-Cash (O2C) process involves the flow of business transactions from order placement to payment collection, facilitating automation between a buyer and a seller. Using the X12 standard, various EDI transaction sets are exchanged at different stages of this process.

Steps in the Order-to-Cash Process with EDI X12 Transactions:

---

1. Purchase Order (850)

• EDI Transaction Set: 850 - Purchase Order
• Purpose: The buyer sends the 850 Purchase Order to the seller, indicating the products or services they want to purchase, along with quantities, delivery dates, and terms.
• Example: A retailer sends an 850 Purchase Order to their supplier requesting 1,000 units of a specific product.

---

2. Purchase Order Acknowledgment (855)

• EDI Transaction Set: 855 - Purchase Order Acknowledgment
• Purpose: The seller responds to the 850 Purchase Order with an 855 Purchase Order Acknowledgment to confirm the receipt of the order, accept or reject the terms, or propose modifications (such as quantity, price, or delivery date).
• Example: The supplier responds by acknowledging the order and confirming that they can fulfill it by the requested delivery date.

---

3. Advance Ship Notice (856)

• EDI Transaction Set: 856 - Advance Ship Notice (ASN)
• Purpose: Before shipping the goods, the seller sends an 856 ASN to the buyer. This transaction provides details about the shipment, including packing information, the contents of the shipment, carrier details, and the expected delivery time.
• Example: The supplier sends an 856 ASN to notify the retailer about the shipment, including tracking information and shipment contents (such as number of boxes and pallets).

4. Shipment and Receiving (Warehouse Transactions)

• EDI Transaction Sets:
• 940 - Warehouse Shipping Order: Sent to direct the warehouse to ship the goods.
• 945 - Warehouse Shipping Advice: Confirms the shipment of goods from the warehouse.
• 944 - Warehouse Stock Transfer Receipt Advice: Confirms the receipt of a stock transfer shipment.
• Purpose: If a warehouse is involved, these transactions are used to manage the movement and storage of goods before delivery.

5. Goods Receipt and Receiving Advice (861)

• EDI Transaction Set: 861 - Receiving Advice/Acceptance Certificate
• Purpose: When the buyer receives the goods, they may send an 861 Receiving Advice to acknowledge receipt and confirm whether the delivery was complete and accurate. It can also be used to notify the seller of any discrepancies (such as damaged or missing goods).
• Example: The retailer sends the 861 Receiving Advice to the supplier confirming receipt of the shipment and noting any damaged items.

---

6. Invoice (810)

• EDI Transaction Set: 810 - Invoice
• Purpose: After the goods have been shipped, the seller sends an 810 Invoice to the buyer. The invoice includes details such as product quantities, prices, taxes, discounts, and payment terms.
• Example: The supplier sends an 810 Invoice to the retailer for the delivered products, specifying the total amount due, taxes, and payment terms.

---

7. Functional Acknowledgment (997)

• EDI Transaction Set: 997 - Functional Acknowledgment
• Purpose: The 997 Functional Acknowledgment is used to confirm the receipt of EDI messages and to indicate whether the received documents (such as 850, 855, or 810) are syntactically correct.
• Example: After receiving the 810 Invoice, the retailer sends a 997 to the supplier, acknowledging that the invoice was received and processed successfully.

---

8. Payment and Remittance Advice (820)

• EDI Transaction Set: 820 - Payment Order/Remittance Advice
• Purpose: The buyer sends the 820 Payment Order/Remittance Advice to the seller's bank to initiate payment. It includes payment details, such as invoice numbers, amounts paid, and any deductions or adjustments (such as discounts).
• Example: The retailer sends an 820 to the supplier’s bank, specifying the amount paid for the invoice, and sends a remittance advice to the supplier with details about the payment.

---

9. Credit/Debit Adjustments (812)

• EDI Transaction Set: 812 - Credit/Debit Adjustment
• Purpose: If any discrepancies occur (e.g., overcharges, undercharges, or returns), the buyer or seller can send an 812 Credit/Debit Adjustment to adjust the invoice amounts. This is typically sent after invoicing.
• Example: The retailer finds an overcharge on the invoice and sends an 812 Debit Adjustment to the supplier for a refund or credit adjustment.
