5 Common Mistakes in Purchase Order Processing and How to Avoid Them

5 Common Mistakes in Purchase Order Processing and How to Avoid Them

For any business that procures goods or services, the purchase order (PO) is the cornerstone of a controlled and accountable procurement process. It serves as a legal document, a communication tool for suppliers, and a critical record for your finance and receiving departments. However, the journey from requisition to payment is often fraught with manual errors and procedural gaps that can lead to significant operational and financial headaches.

Streamlining your purchase order processing isn't just about administrative tidiness; it's about saving money, strengthening supplier relationships, and ensuring operational continuity. Let's explore five of the most common mistakes companies make and, more importantly, how you can avoid them.

1. Relying on Manual Data Entry and Paper-Based Systems

The Mistake: Manually typing PO details from emails, spreadsheets, or paper forms into your system is a recipe for disaster. This approach is incredibly time-consuming and prone to a high rate of errors—incorrect item codes, typos in quantities, wrong prices, or mistaken delivery dates. These errors cascade, causing receiving discrepancies, invoice mismatches, and prolonged approval cycles.

How to Avoid It: The solution is automation. Invest in a dedicated Procure-to-Pay (P2P) or Purchase Order software. These systems allow for:

• Electronic Creation & Submission: Requisitions and POs are created from standardized digital catalogs or templates.
• Automated Workflow Routing: POs are automatically sent to the correct approvers based on predefined rules (e.g., value, department).
• Integration: Seamless connection with your ERP, inventory, and accounting software ensures data consistency across all platforms, eliminating re-keying.

2. Incomplete or Vague Purchase Order Information

The Mistake: Sending a PO that lacks critical details is an invitation for confusion. Missing information like precise item descriptions (part numbers, SKUs), clear delivery instructions (dock number, contact person), specific payment terms, or project codes forces the supplier to make assumptions or seek clarification. This leads to delays, wrong shipments, and invoice reconciliation nightmares.

How to Avoid It: Implement mandatory field requirements in your PO system. Create comprehensive PO templates that force users to include:

• Full, unambiguous product/service descriptions.
• Agreed-upon unit price and total price.
• Exact delivery date and location instructions.
• Requisition number and GL account coding.
• Clear terms & conditions (e.g., penalty for late delivery).

Treat the PO as the single source of truth for the transaction.

3. Poor Communication and Lack of Confirmation with Suppliers

The Mistake: The process doesn't end when you click "send." Assuming the supplier has received, acknowledged, and accepted your PO without confirmation is a major risk. They may be out of stock, have questions about the specs, or may not agree to the terms. Without formal acknowledgment, you have no guarantee your order is in production.

How to Avoid It: Establish a formal PO acknowledgment process. Many PO systems offer electronic portals where suppliers must log in to view, accept, or reject orders. At a minimum, require an email confirmation from the supplier. This acknowledgment should confirm they have received the PO, agree to all terms, and can meet the delivery date. This step creates a contractual paper trail and prevents "I never received it" disputes.

4. Neglecting the Three-Way Match

The Mistake: Approving supplier invoices for payment without verifying them against the original PO and the receiving report is a primary cause of overpayment. You might pay for quantities not received, pay higher prices than agreed, or even pay for items you never ordered. This directly hits your profitability.

How to Avoid It: Enforce a strict Three-Way Match policy for every invoice. Before any payment is released, your accounts payable team must cross-check three documents:

1. Purchase Order: What was ordered and at what price?
2. Receiving Report/Packing Slip: What was actually delivered?
3. Supplier Invoice: What is being charged?

All three must align in quantity, price, and description. Automated P2P systems can flag discrepancies instantly, allowing for quick resolution with the supplier.

5. Failing to Track PO Status and Manage Exceptions

The Mistake: Once a PO is issued, many companies file it away and forget about it until an invoice arrives or the delivery date passes. This reactive approach means you are unaware of delays, partial shipments, or quality issues until it's too late to mitigate the impact on your operations.

How to Avoid It: Implement active PO lifecycle management. Use your PO software's dashboard to track the real-time status of all open orders. Proactively manage exceptions such as:

• Late Deliveries: Set up alerts for approaching and missed delivery dates.
• Partial Shipments: Clearly track what has been received versus what is still outstanding.
• Quality Issues: Link POs to a non-conformance report process for defective goods.

Regular communication with suppliers about order status builds stronger partnerships and allows for better planning on your end.

Conclusion: Building a Robust PO Process

Mistakes in purchase order processing are costly, but they are also largely preventable. By moving away from manual, error-prone methods and embracing digital tools and standardized procedures, you can transform your procurement function from a clerical burden into a strategic asset. Focus on automation to reduce errors, clarity to prevent confusion, confirmation to ensure alignment, verification (three-way match) to protect finances, and proactive tracking to manage performance. Addressing these five common areas will lead to faster cycle times, stronger supplier relationships, better cost control, and a more resilient supply chain for your business.
