Why Order Accuracy Breaks at Scale and How Multichannel Sellers Fix It

When you're processing 50 orders a day, it's relatively easy to keep an eye on what's being picked, packed, and shipped.

Your team probably knows the process inside and out, and if something goes wrong, it's usually easy to spot the problem, figure out what happened, and fix it.

But what happens when you're processing 500 or 5,000 orders a day across Amazon, Walmart, Shopify, and other sales channels? Suddenly, keeping everything accurate becomes a lot more difficult.

A single inventory discrepancy can result in an order being accepted for an item that's no longer available. A picking mistake can mean the wrong SKU gets shipped. A missed order can lead to a delayed delivery and an unhappy customer.

As your ecommerce operation grows, small gaps in your processes become harder to manage. The manual checks that worked when you had 50 orders a day may not be enough when you're handling thousands.

So, how can you maintain order accuracy as your business grows?

The key is to build workflows that make it easier for your team to get orders right the first time. Centralized inventory, synchronized sales channels, automated workflows, and fulfillment checks can all help reduce errors as your operation becomes more complex.

In this post, we’ll dig into why order accuracy gets exponentially harder as your ecommerce business scales, and how you can fix the problem. 

Why Order Accuracy Gets Harder as You Scale

There are several reasons why maintaining order accuracy becomes more challenging as your business grows. Let's take a look at some of the biggest ones.

1. More Orders Mean More Opportunities for Mistakes

The first reason is the most obvious one: The more orders you process, the more opportunities there are for something to go wrong.

For every order you receive, your team will need to:

If there’s even a small error rate affecting your operations, this will add up very quickly. For example, let's say your operation has a 1% order error rate. That might sound relatively low. But if you're processing 5,000 orders, that's potentially 50 orders with a problem.

Those errors can have a bigger impact than simply needing to resend an item. A wrong-item shipment can result in a return, a delayed order can lead to a customer complaint, a missed order can affect your marketplace performance, and a mistake in inventory can create problems across multiple sales channels.

As order volume increases, you need systems that can help your team maintain accuracy without requiring them to manually check every order.

2. Multiple Sales Channels Create More Complexity

In addition to order volume causing issues, the risk also grows when the number of sales channels you’re managing increases. 

Amazon, Walmart, and Shopify all have their own orders and inventory information. Each channel also has different shipping requirements and fulfillment workflows. 

If you're managing these channels separately, your team may have to switch between multiple platforms just to find out what's been ordered and what needs to happen next.

For example, your team might need to:

  1. Check Amazon for new orders.

  2. Check Walmart for new orders.

  3. Check Shopify for new orders.

  4. Enter or transfer order information into another system.

  5. Check inventory before assigning the order for fulfillment.

The more places your team has to look, the more opportunities there are for an order to be missed or information to become outdated.

A centralized order management system can help by bringing orders from different channels into one place. Instead of checking each marketplace individually, your team can work from a single view of what has been ordered and what needs to be fulfilled.

3. Inventory Discrepancies Can Turn Into Fulfillment Errors

Order accuracy starts before an order reaches the warehouse. If your inventory information isn't accurate across your sales channels, you can accidentally accept an order for a product you don't actually have in stock.

Now your fulfillment team has to figure out what to do.

They may need to:

None of these are ideal solutions.

Accurate inventory synchronization helps prevent these problems from happening in the first place. When an item sells on one channel, the inventory count should be updated across your other channels as quickly as possible.

This gives your team a more accurate picture of what's actually available and helps reduce the risk of overselling.

For sellers managing multiple warehouses, inventory buffers can also provide an additional layer of protection when stock levels are unpredictable. The goal is to make sure your sales channels and fulfillment team are working from the same inventory information.

4. Manual Processes Don't Scale Cleanly

If you're processing a manageable number of orders, manually checking a marketplace or entering an order may only take a few minutes. The problem is that these tasks become much more difficult to manage as order volume increases.

Consider some of the repetitive tasks your team may be handling manually:

Each task creates another opportunity for human error. When your team is doing these things hundreds or thousands of times, even a small error rate can become significant.

Instead of spending their time fulfilling orders, your team may find themselves constantly checking whether information is correct or fixing problems that have already occurred.

That's when it's time to start looking at which parts of your workflow can be automated.

5. You Can't "Hustle" Your Way Out of Workflow Flaws

When order accuracy starts slipping, it can be tempting to ask your team to simply be more careful.

Double-check the order. Check the SKU one more time. Make sure the address is correct before shipping.

These extra checks can help in the short term. But if your underlying workflow is creating unnecessary opportunities for mistakes, asking your team to work harder won't solve the problem.

The manual processes that helped you get your business off the ground can become bottlenecks as you grow.

For example, if your team has to manually check five marketplaces for new orders, copy information between systems, and reconcile inventory counts, there's only so much additional effort they can put in.

As order volume grows, these tasks take up more time. And the more manual work your team has to manage, the harder it becomes to catch every mistake.

By centralizing information, automating repetitive tasks, and adding accuracy checks to your fulfillment workflow, you can reduce the number of opportunities for errors and give your team a more reliable process to follow.

How Multichannel Sellers Improve Order Accuracy

So, what can you do to improve order accuracy as your ecommerce operation grows?

Here are five strategies that can help.

1. Create a Single Source of Truth

One of the simplest ways to reduce order errors is to give your team one place to manage orders and inventory.

Instead of checking Amazon, Walmart, Shopify, and other sales channels separately, a centralized system can bring this information together.

Then, your team will be able to see:

This can reduce the amount of time your team spends switching between platforms and make it easier to identify what needs to happen next.

A centralized system also makes it easier to track accountability. If someone needs to check the status of an order, they know where to look. Goflow brings orders, inventory, listings, fulfillment, and shipping information together in one platform, giving multichannel sellers a centralized view of their operation.

2. Keep Inventory Synchronized Across Channels

When a customer purchases an item on one sales channel, the available inventory needs to be reflected across your other channels. This is essential for accurate order fulfillment. 

For example, imagine you have 10 units of a product in stock.

A customer purchases one on Amazon. If your Shopify inventory still shows 10 units instead of 9, you could potentially sell inventory that you no longer have available. This can lead to canceled orders, delayed fulfillment, and frustrated customers.

Real-time inventory synchronization helps prevent these problems by keeping inventory information aligned across your sales channels. With Goflow, inventory can be synchronized across your connected channels so your team has a more accurate picture of available stock.

For businesses managing multiple warehouses or unpredictable inventory levels, inventory buffers can also help reduce the risk of overselling.

3. Automate Repetitive Order Workflows

Not every decision in your fulfillment process needs to be made manually. If your team makes the same decisions repeatedly, you may be able to turn those decisions into automated rules.

For example, you can use automation to:

Instead of asking an employee to make the same decision hundreds of times, you can establish the rule once and let the system apply it consistently.

This can save your team time while also reducing the chance of an order being handled differently simply because different employees are working on it.

Goflow's automated workflows help multichannel sellers standardize order handling and reduce repetitive manual work.

4. Build Accuracy Checks Into Fulfillment

Automation can reduce many opportunities for error, but it doesn't eliminate the need for accuracy checks in your warehouse. Practical fulfillment processes can help your team catch mistakes before an order reaches the customer.

Depending on your operation, these might include:

For example, barcode scanning can help your team verify that they're picking the correct product rather than relying only on a visual check. When your order information is centralized and your warehouse processes are standardized, it's easier for your team to catch problems before an order ships.

5. Monitor Errors and Look for Patterns

When an order error happens, it's easy to fix the individual problem and move on. But if the same type of error keeps happening, you need to understand why.

Start by tracking fulfillment problems such as:

Then, look for patterns.

Are certain SKUs frequently being confused? Is one warehouse generating more errors than another? Are mistakes happening during a particular step of the fulfillment process?

For example, if you notice that the same two SKUs are regularly being confused, you may need to improve your SKU labeling or change where those products are stored.

If one warehouse has significantly more picking errors than another, you may need to review its fulfillment processes or training. Reporting tools can help you identify these patterns so you can address the underlying problem instead of repeatedly fixing the same mistake.

Goflow's reporting capabilities give sellers greater visibility into their operations, making it easier to identify issues and make informed decisions about their workflows.

Where Goflow Fits In

As your ecommerce business grows, keeping orders, inventory, listings, fulfillment, and shipping information organized can become increasingly difficult. A centralized platform can help simplify that process.

Goflow gives multichannel sellers one place to manage their operations, with tools for:

Instead of relying on multiple systems and manual processes to keep your operation running, you can bring more of your workflow together in one place.

This can help reduce unnecessary manual work, improve visibility, and make it easier for your team to maintain order accuracy as your business grows.

Order Accuracy Shouldn't Depend on Constant Manual Checking

As your business grows, it's normal for your fulfillment processes to become more complicated. You have more orders to process, more sales channels to manage, more SKUs to keep track of, and potentially more warehouses to coordinate.

The processes that worked when you were handling 50 orders a day just won’t cut it when you're handling 500 or 5,000.

By centralizing your order and inventory information, synchronizing inventory across channels, automating repetitive workflows, and building accuracy checks into your fulfillment process, you can make it easier for your team to get orders right.

Don't Let Order Volume Turn Into Error Volume

Goflow gives multichannel sellers one place to manage orders, inventory, fulfillment, and more, so you can scale your operation without adding unnecessary complexity.
