Redefining Delivery KPIs: Measuring What Really Matters During Peak Season

TL;DR: What Are the Most Important Delivery KPIs During Peak Season?

Traditional delivery KPIs like cost per delivery and on-time rates no longer capture what truly drives customer loyalty or profitability. During peak season, retailers that expand KPIs to include customer satisfaction, retention, and return behavior gain a clearer picture of delivery’s real business impact.

What Are Delivery KPIs?

Delivery KPIs are the metrics retailers use to evaluate the performance, cost, and customer impact of last-mile delivery operations. While legacy KPIs focus on efficiency and speed, modern delivery KPIs also measure how delivery influences customer experience, loyalty, and long-term revenue.

Why Do Traditional Delivery KPIs Fall Short During Peak Season?

Traditional delivery KPIs fall short because they focus on cost and speed while overlooking customer experience and long-term value.

For decades, brands gauged shipping performance by two metrics: cost per delivery and on-time rates. These metrics provided a simple benchmark for measuring efficiency. But in today’s volatile retail environment, this simplicity often hides complexity.

According to Veho and Supply Chain Dive’s recent survey of more than 150 retail supply chain leaders, legacy KPIs leave critical blind spots. Thirty-six percent of logistics leaders still believe cost per delivery is the most important delivery KPI, while only 19 percent track delivery-related complaints. Just 25 percent consider return rates a key delivery metric.

That gap is telling.

The metrics that most directly reflect customer loyalty and long-term profitability are often ignored in favor of cost metrics that paint an incomplete picture. When brands fail to connect these dots, they risk missing the true cost of delivery. High efficiency on paper can mask friction points that quietly erode trust, loyalty, and lifetime value.

Why Delivery KPIs Matter More During Peak Season?

Peak season magnifies every weakness in the delivery experience. Higher volumes, tighter delivery windows, and increased customer expectations make it harder for legacy KPIs to tell the full story.

When retailers rely solely on cost and on-time metrics during peak periods, they often react too late—after customer dissatisfaction, churn, or brand damage has already occurred. A broader KPI framework provides early signals that allow teams to act before problems escalate.

What Delivery KPIs Should Retailers Measure?

Retailers are increasingly expanding their KPI frameworks to include customer-centric metrics that reflect the full impact of last-mile delivery. These KPIs provide a more accurate view of both profitability and customer loyalty.

Customer satisfaction scores tied to delivery:

‍Post-purchase surveys and Net Promoter Scores reveal whether customers experience delivery as seamless or frustrating. High satisfaction correlates with repeat business, while declining scores can surface issues before they become systemic.

Support and restitution costs tied to shipping failures:

‍Customer support interactions, refunds, and credits expose the hidden costs of late or damaged deliveries. Tracking these costs offers a more realistic view of delivery profitability beyond transportation spend alone.

Repurchase and retention rates:

‍Customer retention is one of the strongest predictors of long-term revenue. By linking repurchase behavior to delivery performance, retailers can quantify how reliability directly influences lifetime value. Even modest improvements in retention can produce exponential returns.

Average order value growth tied to delivery reliability

‍Customers who trust a retailer’s delivery experience are more likely to increase basket size. Monitoring order value alongside delivery KPIs helps retailers understand how logistics investments translate into incremental revenue.

‍

Together, these KPIs make one thing clear: delivery is not just an operational function. It is a core driver of customer experience, profitability, and brand reputation.

Why Delivery KPIs Should Start With the Customer Experience

The most effective delivery strategies begin with the customer and work backward.

Industry experts consistently emphasize this point. As Nate Skiver explains:

“Brands should create a delivery strategy with their customers in mind, and work back from there to put the right resources in place to execute that strategy.”

A customer-first KPI approach requires measuring not only operational efficiency, but also outcomes that matter to buyers. Did the delivery experience strengthen trust? Did it reduce friction in the purchasing journey? Did it increase the likelihood of repeat purchases?

When retailers treat logistics as a customer experience touchpoint instead of a back-end operation, delivery shifts from a cost center to a competitive differentiator.

How Redefining Delivery KPIs Helps Retailers Win Peak Season

Redefining delivery KPIs is not an academic exercise—it is a practical strategy for navigating peak season successfully. Retailers that broaden their measurement approach gain the ability to make smarter, more targeted investments.

Identify where delivery failures drive churn

‍Data from delivery complaints, support tickets, refunds, and returns highlights the exact friction points pushing customers away.‍

Justify investments in delivery technology

‍Customer-focused KPIs strengthen the business case for tools like AI-powered exception management, predictive ETAs, and dynamic routing. These technologies directly reduce friction and improve delivery accuracy.

Strengthen Return on Shipping (ROS)‍

By linking delivery performance to customer lifetime value, retailers can demonstrate that shipping is not a sunk cost. Measuring ROS reframes delivery as a growth lever that drives retention, revenue expansion, and brand loyalty.

In the words of one supply chain leader, delivery is the final mile of the customer experience, and the first mile of customer loyalty. Retailers that redefine their delivery KPIs now will be the ones setting the standard for peak season success and long-term growth.

Frequently Asked Questions About Delivery KPIs

What are the most important delivery KPIs during peak season?
The most important delivery KPIs include customer satisfaction, support and restitution costs, repurchase and retention rates, and average order value tied to delivery reliability.

Why is cost per delivery not enough?
Cost per delivery measures efficiency but ignores customer experience, churn, and hidden costs like refunds and support interactions that directly impact profitability.

How do delivery KPIs affect customer retention?
Reliable delivery builds trust. When retailers link delivery performance to repurchase behavior, they can directly measure how logistics drives loyalty and lifetime value.

What is Return on Shipping (ROS)?
Return on Shipping measures how delivery investments contribute to customer lifetime value and revenue growth, reframing shipping from a cost to a strategic advantage.
