The Purchase Order Process

Understanding the purchase order process involves tracing its journey from creation to fulfillment. Let’s break down the steps involved in the life cycle of a typical purchase order.

1. Need Identification:

Before a purchase order is even on the horizon, there is a need that prompts its creation. Businesses may have different reasons for needing things like more inventory, new equipment, or outside services. Once the need is identified, the purchasing department kicks into action.

2. Creation of the Purchase Order:*

The purchasing department, armed with the specifics of what is required, generates a purchase order. This involves detailing the quantity, quality, and any other relevant information about the goods or services needed. Creating a purchase order requires teamwork between company departments to make sure it’s accurate and complete.

3. Internal Approval Process:

Before the purchase order is sent to the supplier, it typically undergoes an internal approval process. This may involve obtaining approval from various stakeholders, such as department heads, finance teams, or higher management. The goal is to ensure that the purchase aligns with the company’s budget and strategic goals.

4. Transmission to the Supplier:

Once internal approvals are secured, the purchase order is transmitted to the supplier. This can be done through various means, such as email, fax, or through an electronic procurement system. The supplier then reviews the purchase order and acknowledges receipt.

5. Order Confirmation:

After getting the order, the supplier checks if they can fulfill it as requested. If there are any discrepancies or issues, the supplier may communicate with the buyer to resolve them. Once both parties are in agreement, the supplier confirms the order and acknowledges their commitment to fulfilling it.

6. Order Fulfillment:

With the order confirmed, the supplier proceeds to fulfill the requirements outlined in the purchase order. This may involve manufacturing goods, packaging them, and arranging for their delivery. In the case of services, the supplier may begin the agreed-upon work.

7. Shipping and Delivery:

If you buy something physical, the seller sends it to you by the agreed delivery date. When shipping, a notice or slip is made to list what is in the package.

8. Receipt and Inspection:

After getting the goods or services, the buyer checks them to make sure they match the details in the order. This step is crucial as it allows the buyer to identify any discrepancies or defects in the delivered items.

9. Invoice Generation:

Once the buyer confirms the satisfactory receipt of the goods or services, the supplier generates an invoice. The invoice usually has information like the PO number, item descriptions, quantities, prices, and taxes or fees.

10. Payment Processing:

The buyer processes the invoice and initiates the payment according to the agreed-upon terms. This may involve sending a payment through electronic funds transfer, issuing a check, or using another accepted payment method.

11. Record Keeping:

Both the buyer and the seller maintain records of the purchase order, order confirmation, shipping documents, and invoices. These records serve as a crucial reference for future transactions, audits, and financial analysis.
