Procure-to-Pay (P2P) Process with EDI X12 Transactions

The EDI Procure-to-Pay (P2P) process involves the exchange of electronic documents between a buyer and a supplier to facilitate the purchase of goods or services, from requisition to payment. In this process, EDI X12 standards are commonly used to transmit various transactions between the buyer and supplier, streamlining procurement, invoicing, and payment processes.

Steps in the EDI Procure-to-Pay Process with X12 Transactions:
1. Purchase Requisition (Internal Step):

• The P2P process starts with the buyer identifying a need for goods or services. A requisition is created internally to request the purchase.

• EDI Transaction: None (This is an internal process step).

2. Request for Quotation (Optional):

• The buyer may issue a request for a quote from multiple suppliers to get the best price for the required goods or services.

• EDI Transaction: EDI 840 (Request for Quotation).

3. Supplier Quotation:

• The suppliers respond with their quotations, providing pricing and availability details.

• EDI Transaction: EDI 843 (Response to Request for Quotation).

4. Purchase Order (PO):

• The buyer sends a purchase order to the selected supplier, outlining the specific goods or services needed, quantities, delivery dates, and prices.

• EDI Transaction: EDI 850 (Purchase Order).

• Purpose: The 850 PO message serves as the formal request for goods or services, initiating the procurement process.

5. Purchase Order Acknowledgment:

• The supplier confirms receipt of the purchase order and indicates whether they can fulfill the order as requested.

• EDI Transaction: EDI 855 (Purchase Order Acknowledgment).

• Purpose: This transaction ensures that both parties are aligned on the order details, including any changes to the PO.

6. Advance Shipping Notice (ASN):

• The supplier sends an advance shipping notice to the buyer when the goods are shipped, providing details about the shipment, such as expected delivery date, packaging, and contents.

• EDI Transaction: EDI 856 (Advance Shipping Notice).

• Purpose: The buyer uses the ASN to prepare for the arrival of goods, ensuring the correct items are received.

7. Goods Receipt:

• The buyer receives the goods and verifies the delivery against the purchase order and the ASN.

• EDI Transaction: None (This is an internal process step).

8. Invoice:

• After the goods or services have been delivered, the supplier sends an invoice to the buyer, detailing the products provided, quantities, prices, and payment terms.

• EDI Transaction: EDI 810 (Invoice).

• Purpose: The invoice serves as the official request for payment from the supplier to the buyer.

9. Payment Order/Remittance Advice:

• The buyer processes the invoice and sends payment to the supplier. The buyer may also send a remittance advice, notifying the supplier that payment has been made and specifying which invoices are covered by the payment.

• EDI Transaction: EDI 820 (Payment Order/Remittance Advice).

• Purpose: The remittance advice informs the supplier that payment has been issued, facilitating financial reconciliation.
