Sales Order vs Purchase Order: Key Differences You Should Know

In the world of business transactions, sales orders and purchase orders are crucial documents with distinct roles. Despite their surface similarities, these documents are used for different purposes and by different parties.

Confusing sales orders with purchase orders can lead to significant issues such as processing errors, delays, and miscommunication. For instance, if a sales order is mistakenly treated as a purchase order, it might result in incorrect inventory management or shipment problems. Similarly, treating a purchase order like a sales order could lead to issues with supplier fulfillment and order accuracy. Recognizing and managing these documents properly helps prevent such disruptions and maintains the smooth flow of transactions.

How Sales Order and Purchase Order Work

The key to effectively distinguishing between a purchase order and a sales order lies in understanding the distinct roles these documents play within the broader order process. By comprehending the purpose and function of each order type, businesses can streamline their operations, ensure accurate inventory management, and enhance customer satisfaction.

Moreover, a clear understanding of the roles of purchase orders and sales orders enables organizations to maintain accurate financial records and facilitate smooth communication between suppliers and customers. So, let’s take a closer look at how sales order and purchase order work below:

1. The buyer initiates the order

The step where the buyer initiates the order is an essential part of the overall order process. It marks the beginning of the transaction and involves the buyer expressing their interest in purchasing a product or service. This step is crucial as it sets the entire process in motion and provides the necessary information for the seller to proceed with fulfilling the order.

The buyer initiates the order by directly contacting the seller or using a specific platform provided by the seller, such as an online shopping website or a mobile app. This step can take various forms, depending on the nature of the business and the channel used for initiating the order.

Buyer:

• Initiate the procurement process by determining what is needed to be purchased.
• This step involves the purchasing officer or procurement team interacting with different departments and personnel within the buyer’s organization to gather purchase requests. By coordinating with various stakeholders, the buyer ensures that all necessary input and requirements are considered in the purchasing decision.

Seller:

• No immediate action is needed. The role is fairly minimal in this step.
• The seller only needs to be prepared to respond when the buyer reaches out with their purchase requisition or inquiry.

2. The buyer prepares the purchase order

This step entails the buyer initiating the request for a specific product or service from a supplier. This step is often the result of careful consideration and evaluation of the buyer’s needs, budget, and requirements.

When the buyer prepares the purchase order, they usually include various essential details. Hence, the buyer’s preparation of the purchase order allows them to clearly communicate their expectations and requirements to the supplier. It provides a written record of the requested items and helps minimize misunderstandings or disputes that may arise during the fulfillment process. By including all the necessary information, the buyer ensures that the supplier understands what is being requested.

Buyer:

• The purchasing officer will begin by going over the supplier list to assess which supplier is best suited to fulfill the order requirements. Factors such as supplier reliability, product quality, pricing, and past experiences will be taken into consideration.
• Once a suitable supplier has been selected, the officer will proceed to prepare the purchase order. This involves clearly specifying the product or service details, including the name, quantity, pricing information, delivery date, payment terms, and any specific instructions or specifications necessary.
• The prepared purchase order will then be submitted for internal approval within the organization. Large purchase orders typically require approval from the finance head or business owner, who will carefully review and authorize them. Smaller purchase orders, such as those for office supplies, may be approved by a lower-level manager with appropriate decision-making authority.

Seller:

• The buyer may reach out for updated price lists or any other relevant information. This request is to ensure that the purchase order accurately reflects the most current pricing details. Hence, the seller needs to be ready for that.

3. The buyer sends the purchase order to the seller

This step is a critical moment in the transaction, as it marks the formal communication of the buyer’s intent to purchase and outlines the specific details of the order. The purchase order serves as a legally binding document and ensures clarity between the buyer and the seller regarding the products or services to be provided and the terms of the agreement.

Buyer:

• The purchasing officer, who is the buyer, will proceed to send the purchase order to the seller. There are several common methods the buyer may use to send the PO:

– Email: The purchasing officer can send the purchase order as an attachment via email. They will ensure to address it to the appropriate contact at the seller’s organization, such as the sales representative or order processing team.

– Phone: In some cases, the buyer may opt to call the seller directly to place the order verbally over the phone. They would provide all the necessary details, including the items, quantities, and specific instructions.

– Online order form: Many sellers offer an online order form on their website or portal. The purchasing officer can fill out the required fields, input the relevant details of the order, and submit it electronically.

Seller:

• The seller can provide clear instructions to the buyer on how they can submit the order. This can include specifying the preferred method of communication.
• To facilitate a smooth order submission process, the seller can provide his email address to the buyer. This allows them to send the purchase order directly to your designated email. Alternatively, if there is a customer portal, the seller can provide the buyer with access details, allowing them to submit the order through the portal.

4. The seller receives and reviews the purchase order

Upon receiving the purchase order, the seller plays a crucial role in ensuring that all the details are accurate and aligned with their capabilities and resources. The review process in this step empowers the seller to make an informed decision about moving forward with the order.

By thoroughly assessing the purchase order, the seller can mitigate potential risks or issues that may arise during the fulfillment process. It also ensures that the seller can meet the buyer’s expectations and deliver the products or services accurately and on time.

Buyer:

• The buyer waits for the seller’s confirmation of receiving the purchase order. This confirmation serves as an acknowledgment that the seller has received the order and will proceed with reviewing and fulfilling it.
• If the seller has any questions or concerns regarding the purchase order, the buyer may need to provide clarification or additional information. They should be responsive and promptly address inquiries to ensure smooth communication and resolve potential issues.

Seller:

• The seller should promptly acknowledge receipt of the purchase order.
• The seller carefully reviews the document. This review entails checking for any errors, inconsistencies, or missing information that may affect the fulfillment of the order.
• The seller will cross-reference the order details with their product catalog or service offerings to confirm they can fulfill the buyer’s requirements.
• The seller may also evaluate the terms and conditions specified in the purchase order, such as payment terms, warranties, or special requirements.

5. The seller may contact the buyer regarding the purchase order’s content

This step is crucial in ensuring clear communication, resolving any discrepancies or concerns, and confirming that both parties are aligned in their understanding of the order details.

The purpose of the seller contacting the buyer is to ensure that the purchase order’s content accurately reflects the buyer’s intentions and requirements. By engaging in conversations, both parties have the opportunity to address any potential misunderstandings or errors that may have occurred during the order placement process.

Buyer:

• To be receptive to communication from the seller in case the seller may reach out if there are specific concerns or questions regarding the content of the purchase order. Hence, be prepared to address any inquiries or provide clarification as needed. Otherwise, no further action is required at this stage.

Seller:

• If there are any specific concerns or questions regarding the purchase order’s content, the seller may initiate contact with the buyer.
• If a particular item listed in the purchase order is unavailable or out of stock, the seller should inform the buyer promptly. In this case, the seller can recommend similar alternative products or provide a timeline for when the item is expected to become available again.

6. The seller approves and prepares the sales order 

This step involves the seller’s confirmation and commitment to fulfilling the buyer’s request. It marks the transition from the evaluation phase to the active processing and preparation for order fulfillment.

Buyer:

• The buyer may receive a confirmation notification from the seller stating that your order has been approved. This notification assures you that the seller has reviewed and accepted the order. 
• The actual sales order may not be forwarded in this step. 

Seller:

• Will approve the sale and begin preparing the sales order if there are no concerns or issues raised regarding the buyer’s order. 
• Keep the buyer updated about the progress of their order. Promptly inform the buyer that their order has been confirmed and is currently being prepared. 

7. The seller sends the sales order to the buyer for confirmation 

In the order process, this step involves the seller sending the sales order to the buyer for confirmation. It is crucial to ensure that the buyer has the opportunity to review the order details and validate their accuracy before proceeding with the transaction.

While this step may not be a mandatory step in every situation, it is highly beneficial for both the buyer and the seller to ensure transparency, accuracy, and agreement on the order details.

Buyer:

• The buyer receives the sales order that needs to be reviewed.

Seller:

• The seller promptly delivers the prepared sales order to the buyer. Ensure that all the relevant information is accurately included in the document.
• Prepared to address any questions or concerns the buyer may have.

8. The buyer reviews and confirms the sales order

This step serves as a final checkpoint to ensure that all details and specifications discussed with the sales representative have been accurately captured in the order. The buyer’s thorough review ensures that there are no discrepancies or misunderstandings regarding the products or services being purchased.

Reviewing the sales order allows the buyer to spot any errors or omissions that may have occurred during the order-taking process.

Buyer:

• Thoroughly review the sales order (including product quantity and prices) so it accurately reflects their requirements and expectations.
• If any discrepancies or errors are identified, the buyer should communicate them to the seller for resolution.
• Once the review is complete and the buyer is satisfied with the order, their expected action is to confirm the sales order.

Seller:

• To provide the buyer with a clear and accurate sales order that includes all the agreed-upon details and specifications.
• If the buyer identifies any discrepancies or errors, the seller’s expected action is promptly addressing and resolving them in collaboration with the buyer.
• Once the buyer confirms the sales order, the seller should consider it as a formal contract and proceed with the fulfillment and delivery process accordingly.
