Last-Mile Delivery
Last-mile delivery is the final step of the supply chain — transporting packages from a distribution center or local hub to the end recipient's doorstep, store, or pickup location. This segment accounts for 40-53% of total shipping costs despite covering the shortest physical distance, making it the most expensive and complex part of parcel logistics.
The last mile is where customer experience and operational efficiency collide. Delivery speed, reliability, and flexibility directly impact customer satisfaction, while route density, failed deliveries, and labor costs challenge profitability.
Why Last-Mile Delivery is So Expensive
The cost concentration stems from several factors:
| Cost Driver | Impact |
|---|---|
| Low stop density | Delivering single packages to dispersed residential addresses (vs. consolidated shipments to centralized facilities) |
| Labor intensity | Driver wages account for 50-60% of last-mile costs; drivers spend more time finding addresses and waiting for recipients than driving |
| Failed deliveries | 10-20% of first delivery attempts fail, requiring re-delivery or return to depot |
| Residential complexity | Apartment buildings, gated communities, unclear addresses extend delivery time |
| Customer expectations | Same-day, next-day, and narrow delivery windows require premium resources |
| Return leg inefficiency | Vehicles often return empty after completing routes |
Unlike line-haul transportation (where trucks move hundreds of packages in one direction at highway speeds), last-mile vehicles make 100-200 stops per route at residential speeds, with constant starting and stopping.
Last-Mile Delivery Models
Businesses use different delivery models based on their product mix, customer preferences, and cost structure:
1. Home Delivery (Traditional)
The carrier delivers directly to the customer's residence or business address.
- Best for: E-commerce, subscription services, time-sensitive goods
- Cost: Highest per-package cost ($5-10+ per delivery)
- Customer value: Maximum convenience, no recipient action required
- Challenges: Failed deliveries, porch theft, narrow delivery windows
Example: Amazon Prime, FedEx Home Delivery, UPS residential service
2. BOPIS (Buy Online, Pick Up In-Store)
Customer purchases online and collects the order from a retail location.
- Best for: Retailers with physical stores, urgent purchases
- Cost: Lowest fulfillment cost (no last-mile delivery expense)
- Customer value: Same-day availability, no shipping fees, ability to inspect product before leaving
- Challenges: Requires store infrastructure, inventory allocation between stores and fulfillment centers
Example: Target, Walmart, Best Buy
BOPIS adoption grew 350% during 2020-2021 and remains popular — 44% of retailers offer click-and-collect as of 2026. It reduces failed deliveries to zero and converts to in-store browse visits.
3. Pickup Lockers / PUDO (Pick Up Drop Off)
Packages are delivered to secure, self-service lockers or partner retail locations where customers retrieve them using a code.
- Best for: Dense urban areas, apartment buildings, customers with unpredictable schedules
- Cost: Medium (consolidated deliveries to one location serve many customers)
- Customer value: 24/7 access, secure storage, flexibility
- Challenges: Locker capacity limits, customer willingness to travel
Example: Amazon Lockers, FedEx OnSite, UPS Access Point
4. Curbside Pickup
Customer orders online and picks up from a designated area outside the store without entering.
- Best for: Grocery, large items, contactless fulfillment
- Cost: Low (no delivery vehicle or route planning)
- Customer value: Speed, convenience, no parking/shopping required
- Challenges: Staging area management, order accuracy
Example: Walmart Grocery Pickup, Starbucks mobile order
5. Crowdsourced / Gig Delivery
Independent contractors using their own vehicles deliver on-demand.
- Best for: Restaurant delivery, same-day local commerce, urgent shipments
- Cost: Variable ($3-15 per delivery depending on distance/demand)
- Customer value: Fast fulfillment (often <1 hour), real-time tracking
- Challenges: Quality control, driver availability, higher cost per package
Example: DoorDash, Uber Eats, Instacart, Postmates

| Curbside | $0 | Same-day | Medium (drive to store) | Grocery, large items, contactless |
| PUDO / Lockers | $3-7 | 1-4 days | Medium (nearby pickup) | Urban areas, secure delivery, flexible customers |
| Home Delivery (Carrier) | $7-12 | 1-3 days | None (doorstep) | Standard e-commerce, nationwide coverage |
| Home Delivery (USPS) | $5-10 | 2-5 days | None (doorstep) | Lightweight packages, budget shipping |
| Crowdsourced | $8-20 | <2 hours | None (doorstep) | Restaurant, grocery, urgent same-day |
Last-Mile Delivery Challenges
1. Cost Pressure
Last-mile delivery costs have increased 7-12% annually since 2020 due to labor shortages, fuel prices, and customer expectations for free/fast shipping. Carriers pass these costs through general rate increases (GRIs) and surcharges, squeezing retailer margins.
2. Failed Deliveries
10-20% of residential deliveries fail on the first attempt because:
- Recipient not home
- Address incomplete or incorrect
- Signature required but no one available
- Access restrictions (gated community, locked building)
Each failed delivery adds $5-8 in re-delivery costs and delays customer satisfaction.
3. Customer Expectations
Consumers expect:
- Free shipping (61% abandon cart if shipping isn't free)
- Same-day or next-day delivery (especially in urban areas)
- Delivery time windows ("deliver between 2-4 PM")
- Real-time tracking and notifications
Meeting these expectations requires premium network infrastructure and higher labor costs.
4. Urban Congestion & Rural Distance
- Urban areas: Traffic, limited parking, high-rise buildings, delivery restrictions slow drivers
- Rural areas: Long distances between stops, lower stop density increase cost per delivery
5. Sustainability Pressure
Delivery vehicles contribute to urban air pollution and CO₂ emissions. Customers and regulators increasingly demand carbon-neutral delivery options, requiring investment in electric vehicles (EVs), route optimization, and alternative delivery methods.
6. Security & Theft
Porch piracy affects 1 in 5 deliveries in some areas. Customers demand secure delivery options (lockers, signature requirements), which add complexity and cost.
Technology & Innovation in Last-Mile Delivery
Route Optimization Software

- Tools: Route4Me, Onfleet, OptimoRoute, Bringg
- Impact: 10-30% reduction in route time and fuel costs
Micro-Fulfillment Centers (MFCs)
Small warehouses (5,000-20,000 sq ft) located in urban areas place inventory closer to customers, enabling same-day delivery and reducing last-mile distance.
- Example: Gopuff dark stores, Amazon Fresh MFCs
- Impact: Faster delivery, lower per-mile cost
Autonomous & Semi-Autonomous Vehicles
- Delivery robots (e.g., Starship, Nuro) handle short-range sidewalk/street deliveries in controlled environments
- Autonomous trucks (e.g., Gatik, TuSimple) transport goods between distribution centers and local hubs
- Status (2026): Limited deployment in select cities; regulatory approval and pedestrian safety remain barriers
Drones
Amazon Prime Air, Zipline, and Wing deliver lightweight packages (<5 lbs) via drone in rural and suburban areas.
- Advantages: Bypass traffic, fast delivery times
- Challenges: FAA regulations, weather, noise, limited payload
Electric Vehicles (EVs)
UPS, FedEx, and Amazon have committed to transitioning delivery fleets to EVs by 2030-2040 to reduce emissions and fuel costs.
- Examples: Rivian EDV (Amazon), BrightDrop EV600 (FedEx)
- Impact: 40-60% reduction in fuel costs, zero tailpipe emissions
Real-Time Tracking & Notifications
GPS-enabled delivery apps provide customers with live driver location, ETA updates, and delivery photo proof, reducing "Where is my package?" inquiries.
