Last-Mile Performance
Last-Mile Performance Drives Results
A framework to help retailers and logistics service providers view the last mile as a unified, measurable business discipline that directly affects revenue, cost, and risk.
What is last-mile performance?
The last mile is one of the most visible, financially consequential parts of the customer journey. Weak performance surfaces as cart abandonment, rising WISMO (where is my order) volume, and carrier risk. Last-mile performance (LMP) is the operating discipline that connects delivery execution to profitable growth. Organizations that treat it as a discipline consistently convert more shoppers, spend less per delivery, and retain more customers.
53% of total shipping costs come from last-mile delivery (Cascadia Capital, 2024)
55% of shoppers will abandon a brand because of a negative delivery experience (Bringg, 2026)
65% of shoppers say a positive delivery experience convinced them to buy again, even at a higher price (Bringg, 2026)
Why does last-mile performance need a shared framework?
These outcomes are usually managed in silos: eCommerce owns conversion, operations owns exceptions, and finance owns margin. The customer experiences all of it as one promise. LMP gives retailers and logistics providers a shared framework to weigh revenue, cost, and risk together, without reducing the conversation to logistics alone.
What metrics matter most?
Great last-mile performance comes down to eight indicators that drive better decision-making and business outcomes.
Revenue metrics
Cart conversion
Completed orders divided by the number of shoppers who reached the delivery-options or shipping-cost stage of checkout
Revenue metrics
On-time in-full (OTIF)
The number of on-time, in-full deliveries divided by total deliveries attempted over a given period
Revenue metrics
Customer rating
An average score per order, driver, region, or delivery window, usually on a 1-to-5 scale collected immediately after delivery confirmation
Revenue metrics
Cancellation rate
Total canceled orders divided by total orders placed within a given period
Cost metrics
Delivery cost
Total delivery expense (fuel, labor, vehicle) divided by number of deliveries or stops in a given period
Cost metrics
Dispatcher cost
Planning labor hours or cost divided by number of routes or orders dispatched
Cost metrics
Customer care cost
Support labor cost divided by delivery volume
Cost metrics
Driver utilization
Active delivery time divided by total paid shift time, broken down further into idle time, drive time, and stop time

How are last-mile performance metrics organized?
The core LMP metrics span three categories: revenue, cost, and risk. Each answers a different question—what drives demand, what drives expense, and what creates exposure—to give businesses a complete view of delivery performance.
Revenue metrics
Revenue metrics tie directly to top-line business outcomes. When they underperform, the impact shows up in lost sales, lost customers, declining lifetime value, and weakened customer trust.
Cancellation rate is the share of placed orders that are canceled before delivery is completed, whether initiated by the retailer, the carrier, or the customer. It reflects demand that was accepted but never fulfilled and is distinct from returns, which occur after a fulfilled delivery.
Calculated as total canceled orders divided by total orders placed within a given period, usually segmented by cause. Retailers separate carrier-driven cancellations (coverage gaps, capacity shortfalls) from merchant-initiated ones (inventory mismatches, pricing errors) since each points to a different root problem and owner.
Cancellation rate exposes whether a business can actually deliver on demand it accepts, not just generate it. Carrier-caused cancellations signal network risk and capacity gaps, especially during peak periods. Merchant-caused cancellations signal broken inventory or fulfillment logic upstream of delivery, both of which erode customer trust immediately.
Rising cancellation rates convert marketing spend into wasted acquisition cost, since the sale never completes. Customers who experience a cancellation are less likely to reorder. Repeated failures during high-demand periods expose capacity planning gaps that compound as volume grows, which often reveal themselves too late to correct.
Customer rating is the score shoppers assign to their delivery experience, typically gathered through post-delivery surveys, app prompts, or star ratings tied to a specific order or driver. It captures subjective satisfaction with the delivery itself, separate from product quality or overall brand sentiment.
Calculated as an average score per order, driver, region, or delivery window, usually on a 1-to-5 scale collected immediately after delivery confirmation. Some retailers weight ratings by order value or customer tier to prioritize feedback from their highest-value, most frequent shoppers.
Customer rating is a leading indicator of repeat purchase behavior that often surfaces dissatisfaction before it shows up in retention or lifetime value metrics. Unlike price or product reviews, it reflects the most recent, most tangible interaction a customer has with a brand after checkout.
Declining ratings foreshadow churn well before it appears in revenue reporting and can offer retailers a narrow window to intervene. Left unaddressed, low ratings compound: dissatisfied customers order less frequently, spend less per order, and are more likely to switch to a competitor after just one poor experience.
OTIF measures whether an order arrives by the promised delivery date, complete and without damage. It combines two conditions, timeliness and completeness, into a single pass-or-fail outcome, since a delivery that is on time but missing items still breaks the customer's expectation.
Calculated as the number of on-time, in-full deliveries divided by total deliveries attempted over a given period. Retailers often segment OTIF by carrier, region, or delivery method to isolate which parts of the network are driving missed promises.
OTIF is the clearest, most direct evidence that a business kept the specific promise made at checkout. Because it's binary, a delivery either meets the promise or it doesn't, it removes ambiguity from performance reporting and ties execution quality straight back to the commitment customers were sold.
Missed OTIF targets drive a predictable chain reaction: rising WISMO (where is my order) contact volume, increased refund and reship costs, and declining customer ratings. Repeated failures push customers toward permanent retailer abandonment, since delivery reliability is one of the hardest broken promises to recover from.
Cart conversion measures how many shoppers complete checkout after reaching the delivery-options step, where cost, speed, and available windows are presented. It isolates the delivery experience's specific impact on purchase completion and is separate from broader site or product-page conversion metrics.
Calculated as completed orders divided by the number of shoppers who reached the delivery-options or shipping-cost stage of checkout. Retailers often break this down further by delivery option selected. They compare conversion across free, standard, and expedited choices to isolate which options actually close sales.
Delivery cost and speed are consistently among the top reasons shoppers abandon a cart, so this stage is one of the last controllable moments before a sale is lost. Cart conversion shows whether the delivery promise itself, not the product or price, is closing or costing the sale.
Poor cart conversion means shoppers reject the delivery promise before an order even ships, which turns marketing and merchandising work into wasted spend. Left unaddressed, this shows up as a persistent revenue leak that's often misattributed to pricing or product issues rather than the actual checkout-stage delivery experience.
Cost metrics
Cost metrics reflect the operational efficiency of last-mile delivery. When they underperform, margin weakens gradually and invisibly until the cumulative impact becomes a financial problem.
Delivery cost is the total expense of getting an order from dispatch to the customer's door, driven primarily by distance traveled and driver time per stop. It captures the direct operational cost to fulfill the delivery promise, separate from upstream fulfillment or warehousing expenses.
Calculated as total delivery expense (fuel, labor, vehicle) divided by number of deliveries or stops in a given period, often expressed as cost per delivery or cost per mile. Retailers and LSPs segment this by route density, region, and delivery type to isolate where costs concentrate.
Delivery cost is the most visible line item tying last-mile execution to margin, and it's the number finance teams scrutinize first. Since it now represents more than half of total shipping cost, small inefficiencies in distance or drive time compound quickly across daily route volume.
Rising delivery costs damage margins on every order, and the pressure often gets passed to the customer as higher shipping fees, which undermine the checkout conversion this framework tries to protect. Left unmanaged, it forces retailers into a bind between raising prices and absorbing losses.
Dispatcher cost is the labor and time expense of planning, assigning, and adjusting routes and driver schedules, including manual intervention required when plans change. It reflects the operational overhead behind getting a delivery plan in place, before a single mile is driven.
Calculated as planning labor hours or cost divided by number of routes or orders dispatched. It’s often tracked alongside time-to-action metrics such as how quickly a dispatcher responds to a delay, cancellations, or reroute requests during an active shift.
Dispatcher cost reveals how much manual effort a network requires to function, which is a direct signal of how automated or fragmented the planning process actually is. High manual intervention slows response time to disruptions and limits how many routes a single dispatcher can effectively manage.
High dispatcher cost caps how much delivery volume a business can scale without proportionally growing headcount. Slow time-to-action on exceptions cascades into missed OTIF targets and rising driver idle time, since delays in replanning routes ripple forward into every subsequent stop on the schedule.
Customer care cost is the expense of handling post-purchase delivery issues, primarily WISMO (where is my order) calls, and the time required to resolve exceptions like delays, damage, or missed deliveries. It captures the cost of a delivery promise that requires intervention to make right.
Calculated as support labor cost divided by delivery volume, and often tracked alongside WISMO call volume as a percentage of total orders and average time-to-resolution per exception. Retailers segment this by cause to see which failure types drive the most support burden.
Customer care cost is a direct, measurable consequence of upstream delivery failures. It’s one of the clearest signals that a visibility or reliability gap exists elsewhere in the network. Every WISMO call represents a customer who didn't trust the delivery promise enough to wait quietly.
Rising customer care cost signals that failures upstream, missed OTIF, poor visibility, are being pushed downstream into support teams rather than prevented. Left unaddressed, it inflates cost-to-serve on every order and signals declining customer confidence long before it shows up in retention numbers.
Driver utilization is the percentage of a driver's paid shift spent on active, productive delivery work as opposed to idle time, waiting, or inefficient routing. It measures how effectively labor capacity is converted into completed stops.
Calculated as active delivery time divided by total paid shift time, often broken down further into idle time, drive time, and stop time. Retailers and LSPs track this per driver, per route, or fleet-wide to identify where capacity goes unused.
Driver utilization is one of the largest levers on delivery cost, since labor is typically the single biggest expense in last-mile operations. Low utilization means a business is paying for capacity it isn't using, regardless of how efficient any individual delivery route looks on paper.
Poor utilization inflates cost per delivery even when routes appear well-planned, since idle time is paid time with no output. It also limits how much volume a fleet can absorb without adding headcount, forcing costlier fixes, like overtime or additional hires, that a better-utilized fleet wouldn't need.
Risk metrics
This category captures the vulnerabilities in the delivery operation that, when unmanaged, lead to service failures and financial loss. Its primary metric is cancellation rate, covered under revenue metrics. That overlap is intentional. A canceled order reads as lost demand or as network risk depending on the cause.
Viewed through risk, cancellation rate measures how often the delivery network itself fails to cover accepted demand, distinct from cancellations caused by pricing or inventory issues upstream. It isolates carrier coverage gaps, capacity shortfalls, and network fragility as the specific cause of the canceled order.
Calculated the same way as the revenue-side metric, canceled orders divided by total orders, but filtered specifically to carrier-driven and capacity-driven causes rather than merchant-initiated ones. Retailers and LSPs track this segment separately and often spike it during peak-season stress tests.
This lens shows whether a network can hold up under real demand, not just whether it can generate demand. Rising carrier-caused cancellations expose capacity and coverage gaps before they become visible anywhere else.Â
A network with high risk-driven cancellations is fragile when volume matters most during peak periods, promotions, or unexpected demand spikes. Left unaddressed, it creates costly last-minute capacity fixes or forces retailers to absorb the reputational cost of failing to deliver at scale.
How do last-mile performance metrics interconnect?
The 8 last-mile performance indicators do not operate in isolation. They form a system of interdependencies where improvement in one metric often produces gains in others, and degradation in one creates compounding problems across the framework.
Revenue and cost connections
- OTIF improvements drive higher customer ratings.
- Higher ratings lead to more repeat purchases and lower cancellation rates.
- Fewer missed windows mean fewer re-deliveries, less driver idle time, and lower WISMO volume.
- Better driver utilization improves OTIF, and better dispatcher efficiency lifts both.
Cost metrics compound
- Greater dispatcher efficiency improves driver utilization.
- Faster created-to-assign times mean fewer idle drivers and more productive delivery time.
- Better route optimization raises drops per hour and lowers delivery cost per order.
- Late assignments cause rushed routes, missed windows, WISMO calls, and increased customer care cost.
Risk as an amplifier
- Cancellation rate's risk dimension acts as a threat multiplier.
- A carrier coverage failure degrades OTIF across routes and spikes WISMO volume.
- It lowers ratings and inflates cost as the business scrambles to recover.
- Carrier diversification, predictive exceptions, and real-time capacity monitoring cut volatility across metrics.
Cart conversion feedback loop
- Cart conversion happens at checkout but runs on trust built beforehand.
- A strong OTIF track record supports tighter delivery promises.
- High customer ratings build the confidence that drives conversion.
- An aggressive promise the operation can't keep damages trust as fast as it captures the order.
Silent retention leakage
- Delivery failures often surface silently as churn and lower customer lifetime value.
- Customers rarely complain, so this gets misattributed to price, product, or competition.
- That misattribution can push a business toward more acquisition spend or discounting to fix the "problem."
- Meanwhile, the real cause sits unaddressed in post-purchase execution, so the leak continues.

What can businesses do with last-mile performance insights?
The value of the framework lies in what organizations do with the insights it generates. The most effective approach follows a structured progression from assessment to action.
1. Assess the current state
- Establish a baseline across all 8 metrics as the first step.
- Most organizations discover gaps in their measurement itself, not just their performance.
- One common gap is tracking OTIF without segmenting it by delivery type.
- Another gap is measuring delivery cost in aggregate without isolating which specific drivers, distance, driver time, or route density, are pushing it up.
2. Benchmark against the market
- Metric values only matter in context, not as standalone numbers.
- An 85% on-time rate sounds reasonable until benchmarked against a 92% industry average for the same delivery type.
- Drops-per-hour varies by use case, same-day grocery differs from big-and-bulky.
- Benchmarks turn data into strategic intelligence and reveal where the business leads or falls behind.
3. Identify high-impact intervention points
- Metrics are interconnected and optimizing the worst-performing one in isolation isn't always the most efficient path.
- A gain in dispatcher efficiency can improve driver utilization, OTIF, WISMO volume, and delivery cost.
- Finding cascading intervention points requires understanding causal relationships between metrics.
- Prioritize interventions by system-wide impact, not by which single metric looks worst.
4. Set targets and build operational plans
- Set specific, time-bound targets for each intervention point once they’re identified.
- Build operational plans that span technology, process, and people.
- The most effective plans tie targets to cross-functional accountability.
- Delivery cost isn't just logistics' problem, and the CX team doesn't solely own the NPS score.
5. Monitor, iterate, and re-benchmark
- Last-mile performance is an ongoing discipline, not a project with an end date.
- The most successful organizations run performance reviews on a regular cadence.
- Re-benchmark against industry data as expectations and capabilities shift.
- Continuous monitoring sustains gains and surfaces new opportunities as they emerge.
6. Expand the aperture
- As the framework matures, extend measurement into adjacent areas.
- Returns performance sits outside the 8 core metrics but influences customer rating and care costs.
- Post-purchase communication quality and delivery option personalization are two additional core indicators.
- The 8 indicators are the foundation for LMP, not the ceiling, and maturity means building outward from them.
