Backorders are one of the common causes of delays in order fulfillment. When products are unavailable at the time an order is placed, businesses must postpone deliveries.

Measuring backorder rate helps companies evaluate inventory performance, identify issues, and determine whether existing inventory planning strategies are sufficient to meet customer demand.

Definition of Backorder

A backorder occurs when a product is unavailable when a customer places an order, but the order can still be processed and fulfilled after stock becomes available.

It usually happens when customer demand exceeds available inventory. It can also result from supply chain disruptions, production delays, or inventory shortages.

Although backorders allow businesses to continue accepting orders, they should be managed carefully.

What Causes Backorders?

Backorders can happen for several reasons. Understanding these causes can help businesses maintain product availability and reduce stockout.

  1. Poor Demand Planning
    Backorders can occur when businesses do not accurately forecast demand. If stock are low, products may run out before replenishment. Without accurate inventory data and planning, stockout can become a recurring issue.
  2. Sudden Increase in Demand
    A sudden increase in demand can quickly deplete available inventory. When orders grow faster than expected, businesses may not have enough stock to fulfill all customer requests immediately.

    As a result, some orders must remain pending until new inventory becomes available.
  3. Supply Chain Delays
    Supply chain issues can also lead to backorders. Delays from suppliers, transportation problems, or logistics challenges can slow the movement of products and affect inventory availability. When products do not arrive on schedule, businesses may struggle to meet customer demand.

Impact of Backorders on Distributors

Backorders are not always negative. In some cases, they indicate that a product is in high demand. However, frequent backorders can create operational challenges.

Positive Impact

  1. Measure Demand
    Backorders can reveal which products are selling faster than expected. This information helps businesses adjust purchasing plans and inventory levels.
  2. Maintain Customer Relationships
    Customers may be willing to wait for products if businesses communicate clearly about stock availability and delivery schedules. Good communication can help maintain customer trust.
  3. Keep Sales Opportunities Open
    Backorders allow businesses to continue receiving orders even when products are temporarily unavailable. Instead of losing sales, companies can fulfill orders after inventory is replenished.

Negative Impact

  1. Increase Operational Costs
    Managing backorders often requires additional administrative work, separate deliveries, expedited replenishment, and schedule adjustments, which can increase operational costs.
  2. Lower Customer Satisfaction
    Long waiting times can frustrate customers, especially when products are needed urgently. Some customers may choose to purchase from competitors instead.
    Affect Business Reputation

    Frequent stock shortages may create the impression that a business cannot consistently fulfill orders. Over time, this can affect customer confidence.

How to Measure Backorder Rate

Backorder rate is a metric used to measure how often customer orders cannot be fulfilled immediately due to inventory shortages.

The formula for calculating backorder rate is:

Backorder Rate = (Total Backorders ÷ Total Orders) × 100%

A high backorder rate indicates frequent stock shortages. If the issue continues, it can lead to delayed deliveries, lower customer satisfaction, and lost business opportunities.

A low backorder rate indicates that inventory levels are sufficient to meet customer demand. It also reflects better inventory planning and product availability.

How to Manage Backorders

With the right strategies, businesses can reduce stock shortages, maintain product availability, and keep backorder rates at a manageable level.

  1. Keep Customers Informed
    Clear communication is important when managing backorders. Customers should receive updates about order status, product availability, and estimated delivery dates.

    Businesses can also offer alternatives, discounts, or shipping incentives to help maintain customer satisfaction while customers wait for their orders.
  2. Improve Demand Forecasting
    Accurate demand planning helps businesses anticipate future inventory needs and prepare for fluctuations in customer demand. Historical sales data, purchasing trends, and market insights can be used to forecast inventory needs with greater confidence.

    Solutions like a Warehouse Management System (WMS) provide inventory visibility and data that support better forecasting and replenishment planning, helping businesses reduce the risk of stock shortages.
  3. Monitor Inventory in Real Time
    Real-time inventory visibility helps businesses track stock levels and identify products that are running low.

    A WMS can help track inventory movement, monitor stock availability, and manage safety stock levels. When inventory reaches predefined thresholds, replenishment can be initiated to support product availability.
  4. Work with Multiple Suppliers
    Relying on a single supplier can increase the risk of stockout. Partnering with multiple suppliers helps businesses maintain a reliable source of inventory and reduce dependency on a single vendor.
