What Is a Backorder? Complete Guide for Ecommerce & Retail (2025 Edition)

Understanding Backorders: Definition & Examples

A backorder occurs when a customer places an order for a product that is temporarily out of stock but is expected to be restocked and shipped at a later date. Unlike an “out of stock” status, which typically means the item is unavailable for purchase, a backorder allows the customer to complete the transaction and wait for delivery.

This situation is common in e-commerce and retail, especially for high-demand items, seasonal products, or goods affected by supply chain delays. Backorders serve as a mechanism for businesses to capture sales even when inventory is low, signaling to customers that replenishment is on the way.

Example 1:
A customer orders a popular pair of sneakers from an online store. The product page notes that the shoes are “on backorder” and will ship in 10–14 business days. The customer completes the purchase and receives the item once new stock arrives.

Example 2:
An electronics retailer allows pre-purchase of a backordered gaming console expected to restock in 3 weeks. The customer secures their unit in advance, and the order is fulfilled when inventory is replenished.

Backorders can help businesses maintain cash flow, manage demand, and reduce customer churn—but only when communicated clearly and managed efficiently. In the next sections, we’ll explore what causes backorders and how to handle them without hurting customer experience.

Why Do Backorders Happen? Common Causes

Backorders can stem from a variety of operational, logistical, or demand-related issues. Understanding the root causes is the first step toward minimizing their impact and ensuring a smoother customer experience.

Here are the most common reasons backorders occur:

1. Unexpected Surge in Demand

When a product suddenly goes viral or experiences a spike in popularity—through social media, a celebrity endorsement, or seasonal trends—inventory can sell out faster than anticipated.

2. Supplier or Manufacturer Delays

Suppliers may struggle with their own production or distribution issues, resulting in late shipments or incomplete deliveries. If your business relies on just-in-time inventory, even a small delay upstream can trigger backorders.

3. Inaccurate Inventory Forecasting

Overestimating how much stock is available or underestimating how much you’ll need can leave shelves empty. Inaccurate demand forecasting is a major contributor to backorder situations, especially in fast-moving sectors.

4. Supply Chain Disruptions

Events like natural disasters, labor strikes, or global crises (e.g., COVID-19) can halt the movement of goods, delay customs clearance, or affect production schedules—leading to product unavailability.

5. Warehouse or Fulfillment Errors

Inventory miscounts, misplaced items, or fulfillment system glitches may lead to stock appearing available in your system, when in reality it’s not.

6. Limited Storage or Capital Constraints

Small or growing businesses may limit their inventory levels due to space or budget restrictions. While lean inventory can reduce costs, it increases the risk of backorders during peak periods.

Recognizing these causes allows businesses to take preventive actions and improve supply chain resilience. In the next section, we’ll clarify how backorders differ from “out of stock” and “pre-orders”, helping you communicate clearly with your customers.

Backorder vs. Out of Stock vs. Pre-order: Key Differences

Many businesses and customers confuse the terms backorder, out of stock, and pre-order, but each represents a different inventory status—with specific implications for communication, fulfillment, and customer expectations.

Here’s a clear comparison of the three:

Backorder

This status indicates the product was available, sold out, and will be restocked soon. Businesses allow customers to place orders now and fulfill them later once stock arrives. It’s common in fast-moving inventory environments.

Out of Stock

The product is currently unavailable and cannot be purchased. No backorder or pre-order option is provided. This often leads to lost sales or customer frustration if not managed properly.

Pre-order

Pre-orders apply to new products not yet released. Businesses collect orders in advance and typically announce a release or shipping date. This is common in tech, fashion drops, and product launches.

Understanding and using the right terminology is critical. Mislabeling a product as “in stock” when it’s on backorder can lead to poor customer experience, chargebacks, and brand trust issues. On the flip side, offering backorders or pre-orders with clear delivery expectations can retain sales while maintaining transparency.

In the next section, we’ll examine how backorders impact your business and customer satisfaction, and why managing them properly is essential for long-term growth.

How Backorders Impact Your Business and Customers

Backorders can have mixed effects on a business. When managed well, they offer a way to capture demand even when inventory is temporarily unavailable. But if handled poorly, they can damage customer relationships and hurt your brand.

Here’s a breakdown of the key impacts:

Customer Experience Risks

1. Frustration & Uncertainty
If customers place an order without knowing it’s backordered—or don’t receive timely updates—they may feel misled or anxious about delivery. Lack of transparency is a top cause of negative reviews and support tickets.

2. Delayed Gratification
Consumers expect fast fulfillment, especially with major retailers offering next-day delivery. Long or vague wait times can cause cancellations or loss of trust.

3. Loss of Repeat Business
Even if customers tolerate one backorder, repeated experiences may drive them to competitors with better inventory visibility or supply reliability.

Operational & Financial Impacts

1. Cash Flow Optimization
On the positive side, backorders allow businesses to secure revenue before restocking, which can improve liquidity—especially useful for small businesses or lean inventory models.

2. Demand Validation
Backorders signal strong product interest. Monitoring backorder frequency helps forecast future stock needs and refine purchasing decisions.

3. Increased Support Load
Backorders often lead to more customer service inquiries, requiring time, resources, and efficient communication systems (e.g., automated updates or FAQs).

4. Inventory & Fulfillment Pressure
Coordinating restocks, partial shipments, or split orders adds complexity to your fulfillment operations. Without proper systems in place, this can lead to errors and increased return rates.

In short, backorders are a double-edged sword. They can protect sales and validate demand, but only when supported by clear communication, accurate timelines, and robust fulfillment processes.

Next, we’ll look at how to manage backorders effectively, step by step—so you can turn them into a competitive advantage instead of a liability.

How to Manage Backorders Effectively (Step-by-Step)

Managing backorders is not just about waiting for stock to arrive. It requires a proactive, transparent, and systematized approach to keep customers informed and operations running smoothly.

Here’s a step-by-step process to manage backorders effectively:

Step 1: Clearly Identify Backordered Items

Ensure your inventory management system can automatically flag products that are out of stock but available for backorder. Use real-time syncing between your store and warehouse systems to avoid discrepancies.

Step 2: Communicate Before Purchase

Transparency builds trust. Clearly label items as “Available on Backorder” and include estimated restock or shipping dates on product pages. Let customers make informed decisions before they buy.

Step 3: Set Realistic Shipping Timelines

Don’t overpromise. Provide conservative estimates for when the item will ship, and account for potential supplier or transit delays. Customers prefer accurate timelines over optimistic guesses.

Step 4: Automate Order & Inventory Tracking

Use inventory management software or ERP tools that track incoming stock and automatically update customers. Sync restock ETAs with your order management system to prioritize fulfillment once inventory arrives.

Step 5: Keep Customers Updated Post-Purchase

Send a confirmation email that clearly states the backorder status. Then, provide regular updates if timelines shift—either via automated emails or customer portals. Proactive communication reduces support volume and boosts satisfaction.

Step 6: Offer Options or Alternatives

If delays are extended, provide customers with choices:

• Wait for delivery
  
• Switch to a similar in-stock product
  
• Cancel the order and receive a full refund
  

Giving control back to the customer increases retention, even when timelines slip.

Step 7: Monitor Metrics & Improve

Track:

• Cancellation rates
  
• Customer support tickets related to backorders
  
• Delivery timeline accuracy
  

Use these metrics to fine-tune your forecasting, communication strategy, and vendor reliability.

When managed with care, backorders can protect revenue, strengthen customer trust, and optimize your supply chain. In the next section, we’ll explore best practices to prevent backorders in the first place—because even well-managed backorders are no substitute for consistent availability.

Best Practices to Prevent Backorders

While backorders can be managed effectively, the best approach is to prevent them from happening altogether. Prevention not only improves the customer experience but also reduces operational costs and customer service load.

Here are proven strategies to reduce and even eliminate backorders from your workflow:

1. Improve Inventory Forecasting

Use historical sales data, seasonal trends, and marketing calendars to anticipate demand. Integrate tools that use predictive analytics to forecast spikes before they occur.

Pro tip: Align forecasts with product launch cycles, promotions, and known seasonal fluctuations.

2. Increase Safety Stock Levels

Build in a buffer by maintaining “safety stock” for your top-selling or high-risk SKUs. While it may slightly increase holding costs, it significantly reduces the risk of missed sales.

3. Audit Suppliers & Lead Times Regularly

Not all suppliers are equally reliable. Audit their on-time performance and lead time consistency quarterly. Switch or diversify vendors if delivery is often delayed.

4. Automate Inventory Alerts

Set up real-time alerts when stock reaches a critical threshold. Many e-commerce platforms and ERP tools allow automated reordering when inventory falls below a set level.

5. Centralize Inventory Data Across Channels

If you sell across multiple platforms (Shopify, Amazon, retail POS), use a centralized inventory system to avoid overselling. Disconnected inventory counts are a major backorder trigger.

6. Consider Dropshipping as a Backup

For select items, partner with a dropshipping provider who can fulfill orders directly when your own stock runs out. This offers continuity without holding excess inventory.

7. Communicate Internally

Ensure that sales, marketing, and fulfillment teams are aligned. Running a major promotion on a low-stock product without notifying inventory managers is a recipe for instant backorders.

8. Conduct Regular Inventory Audits

Physical audits help catch discrepancies between system data and actual stock levels. This is especially important if your team handles fulfillment in-house.

Prevention requires a mix of technology, process discipline, and proactive communication. In the next section, we’ll explore the best tools and tech solutions that can support smarter backorder management and prevention.

Tech Solutions & Tools to Handle Backorders

Backorders are as much a technology problem as a supply chain challenge. Without the right tools in place, it’s nearly impossible to monitor stock levels accurately, automate communication, or forecast demand effectively.

Here are some of the best tech solutions to streamline your backorder management process:

1. Inventory Management Systems (IMS)

Modern IMS platforms help track stock in real time, set reorder points, and flag backordered items instantly.

Top options:

• NetSuite
  
• SAP Business One
  
• Odoo
  

ERPs provide powerful forecasting tools, vendor tracking, and centralized stock visibility across locations and channels.

3. E-commerce Platform Features

Many e-commerce platforms offer built-in backorder support or plugins.

Examples:

• Shopify allows you to accept orders for out-of-stock products with clear messaging.
  
• WooCommerce (with extensions like Back In Stock Notifier or Pre-Orders)
  
• BigCommerce has native tools to manage inventory availability and notifications.
  

4. Demand Forecasting Tools

AI-powered forecasting software helps anticipate inventory needs based on historical data and trends.

Solutions to consider:

An effective OMS ensures accurate stock allocation and prioritizes backordered shipments as soon as inventory is replenished.

By leveraging the right mix of software, businesses can turn backorder chaos into a controlled and transparent process, improving customer satisfaction and operational agility.

In the next section, we’ll showcase real-world examples of brands managing backorders successfully, so you can see these principles in action.

Real-World Examples: Brands Managing Backorders Right

Some of the world’s most trusted brands face regular backorders—especially when launching new products or navigating complex supply chains. What sets them apart is how they communicate, fulfill, and retain customer loyalty during the wait.

Here are three real-world examples of companies handling backorders the right way:

1. Apple – Communicating Delays with Precision

Apple frequently launches high-demand products like iPhones or MacBooks that sell out within hours. When inventory runs low, Apple switches to a “Ships in 2–3 weeks” model and clearly displays delivery estimates on product pages before checkout.

Customers receive:

• Order confirmation with expected ship date
  
• Updates via email when the product is en route
  
• Seamless cancellation or modification options
  

Takeaway: Setting accurate expectations and over-communicating builds trust—even when shipping is delayed.

2. Patagonia – Aligning Backorders with Brand Values

As a sustainable outdoor brand, Patagonia often deals with limited production runs and supply chain challenges. When items go on backorder, they:

• Notify shoppers clearly on product pages
  
• Emphasize sustainability and small-batch manufacturing
  
• Provide realistic ship dates (often 1–3 weeks out)
  

Their messaging aligns with their eco-conscious brand promise, which makes backorders feel intentional, not frustrating.

Takeaway: Use brand values to reframe the backorder as a benefit, not a failure.

3. REI – Offering Backorder Alternatives & Transparency

REI, a major outdoor retailer, often suggests comparable alternatives when high-demand products are on backorder. Their site includes:

• “Expected restock date” displayed next to the product
  
• Links to similar gear in stock
  
• An option to receive email alerts when the item is back
  

Takeaway: Giving shoppers control over how they respond to delays increases retention and reduces cart abandonment.

These examples prove that backorders don’t have to damage your brand. With the right strategy—transparency, proactive communication, and customer-centric options—you can maintain strong loyalty and even increase conversions.

Will I be charged immediately for a backorder?

It depends. Some retailers charge upfront, while others only process payment once the item ships. Always check the billing policy before placing a backorder.

Is it safe to order a backordered product?

Yes—as long as you trust the retailer. Backorders are common and not a sign of poor service. Just make sure the company offers transparent timelines and customer support.

Can I track a backordered item?

You won’t receive a tracking number until the item ships. However, many retailers provide order updates and will notify you once the item is restocked and shipped.

Why do backorders happen so often?

Backorders often occur due to:

• Sudden spikes in demand

They’re common in electronics, fashion, automotive parts, and even books.

How can businesses reduce backorders?

E-commerce businesses can reduce backorders by:

• Improving inventory forecasting
  
• Using real-time stock tracking
  
• Offering pre-order options
  
• Communicating delays clearly to avoid chargebacks or cancellations
  

What’s the difference between “backorder” and “out of stock”?

• Backorder: Item is out of stock but will return soon and is still available for purchase.
  
• Out of stock: Item is unavailable and not purchasable until it’s back in inventory.
  

By addressing these key questions, businesses can reassure buyers, and consumers can make informed decisions when purchasing backordered items.
