How to Improve Order Accuracy and Reduce Fulfillment Errors

If you’re running an eCommerce business, you already know that even a small mistake can create big problems. Whether it’s shipping the wrong item or missing a delivery window, fulfillment errors cost you money and your customers’ trust. This can also leave a lasting dent in your brand’s reputation.

That said, order accuracy isn’t something that’s a nice-to-have—it’s essential. Every perfectly fulfilled order strengthens your customer relationship, boosts your brand image, and protects your margins. On the other hand, errors chip away at loyalty and open the door for competitors to step in.

This article provides actionable strategies for enhancing order accuracy and minimizing fulfillment errors. These tips will help your business deliver a better experience and keep your customers coming back.

Why order accuracy matters in modern fulfillment

When it comes to fulfillment, order accuracy is one of the most important metrics to track. Simply put, order accuracy measures the percentage of orders that are picked, packed, and shipped exactly as the customer requested, with no lapses. The order accuracy rate is computed with this formula:

Order Accuracy Rate = (Number of Accurate Orders ÷ Total Number of Orders) × 100

Let’s say you shipped 1,000 orders last month, and 980 of them were correct. In that case, your order accuracy rate would be 98%.

While a few errors might not seem like a big deal on the surface, the ripple effects can be huge. Incorrect orders lead to:

• Costly returns
• Frustrated customers reaching out to your support teams
• Negative reviews on social media and marketplaces
• Lost trust

When you fail to meet those expectations, it’s all too easy for them to take their loyalty elsewhere.

For scaling brands and 3PLs, order accuracy is even more critical, as small inefficiencies can quickly snowball into major operational headaches. In today’s competitive landscape, perfecting your fulfillment operations is a direct path to customer retention and sustainable growth.

Common causes of fulfillment errors

Even with the best intentions, fulfillment headaches can happen at any stage. To fix them, it’s important to understand where and why they occur. Here are some of the most common reasons fulfillment errors happen:

Error in picking and packing

Picking the wrong item from a shelf or placing the wrong quantity into a package is one of the most frequent causes of order mistakes. When warehouse layouts are confusing or picking instructions are unclear, it’s easy for fulfillment teams to make errors under pressure.

Wrong labels and SKU confusion

Whether it’s applying the wrong shipping label or confusing SKUs, mistakes in labeling can send orders to the wrong customer or result in the wrong item being shipped to someone’s door. Mismanagement of SKUs can also be a huge contributor to fulfillment issues.

Inaccurate inventory counts

When your inventory records don’t match what’s physically available in your warehouse, it can start a chain reaction of problems. You may oversell items that are out of stock and create delays when orders are adjusted, hurting customer trust and increasing returns.

Human error due to manual processes

Manual processes like handwriting labels, updating spreadsheets, or visually verifying orders can lead to unavoidable human error. As order volume grows, relying on manual systems becomes unsustainable and increases the risk of mistakes in the long run.

System integration errors

When your eCommerce platform, warehouse management system (WMS), inventory software, and shipping tools aren’t fully integrated, it can lead to order misfires. Data might not sync in real-time, orders can get duplicated, and critical customer information may be missing.

Strategies to improve order accuracy

Reducing fulfillment errors starts with having the right systems and team practices in place. Below are strategies and tips to boost your order accuracy, especially as your business grows.

Implement barcode scanning and automation

Barcode scanning helps eliminate manual entry errors during picking, packing, and shipping. When employees scan SKUs at every stage of the fulfillment process, the system can verify whether the correct item and quantity are being handled.

Automation tools can take over repetitive tasks like label generation, order confirmation, and inventory updates. This frees up your team to focus on higher-value tasks.

Optimize warehouse layout

A well-organized warehouse layout reduces picker confusion and unnecessary movement. Grouping best-selling SKUs together and clearly labeling zones can minimize the risk of human error while increasing efficiency. The more intuitive and efficient your physical space is, the easier it becomes to maintain high accuracy even during peak seasons!

Adopt inventory management software

Inventory management software (IMS) keeps stock levels updated in real time across channels, ensuring your team knows what’s available and where it can be found. Maintaining consistent visibility over your inventory prevents oversells, eliminates the risk of shipping out-of-stock items, and improves your order fulfillment speed and accuracy.

Audit and refine your order processing flow

Your order processing flow is the backbone of your fulfillment operation. If any step is unclear or inconsistent, errors can slip through. Regular process audits can help identify bottlenecks and inefficiencies while maintaining consistency.

Integrating seamlessly with eCommerce platforms

Disconnects between your eCommerce storefront and fulfillment system often lead to data errors. Integrating platforms like Shopify or Amazon with your warehouse management or order processing system ensures that data flows in real time without the need for manual input. These can save you time and reduce costly corrections.

Regular training and performance monitoring

If your team isn’t properly trained, the best and most advanced technology won’t be able to eliminate every error. Ongoing training ensures everyone follows standardized processes and maximizes your tools’ capabilities. You can pair training with performance monitoring to coach individuals and continuously raise your team’s fulfillment standards.

How technology can help reduce fulfillment errors

Adopting the right technologies can significantly reduce human error, streamline operations, and boost fulfillment accuracy. Here’s a rundown on some of the essential tools that fulfillment teams rely on to get orders right every time:

Inventory management systems (IMS)

An inventory management system (IMS) tracks your stock levels in real time across multiple sales channels and storage locations. It prevents:

• Stockouts
• Overselling
• Sending out-of-date products

This also ensures inventory counts are automatically adjusted after each transaction.

Warehouse management systems

A warehouse management system (WMS) organizes and automates your fulfillment workflow inside the warehouse. From receiving stock to picking, packing, and shipping, a WMS ensures every step is efficient and trackable.

Barcode and RFID scanning

Barcode and RFID technology play a key role in avoiding manual entry errors. By tagging each item, location, or package with a scannable code, your team can verify correct SKUs, track movement, and ensure every item is in the right place at the right time.

Order verification tools

Order verification software adds an extra layer of accuracy by requiring checks at key fulfillment points, especially during packing and shipping. These tools flag incorrect items before they are shipped and capture images of packed orders for proof and customer service.

Predictive analytics and error reporting

Predictive analytics can identify trends in fulfillment errors and take action before they become costly. It can also provide insights to improve training or workflows and support continuous improvement through data-driven decision-making.

Smart shipping tools

Smart shipping tools prevent mislabeling and delivery errors. They verify shipping addresses to reduce failed deliveries and returns. Plus, they can automate label creation and select the best shipping method based on cost and speed.
