Delivery margins are thin. Small leaks add up fast. An extra mile per route, a failed drop, or ten idle minutes per driver can erase the profit on a full day of work.
The numbers show why this matters. Last-mile delivery grew from 41% to 53% of total shipping costs between 2018 and 2023, according to a worldwide study reported by Statista. The final leg is now the largest cost in the chain.
Know Your Cost Per Stop
You cannot fix what you do not measure. Start with one number.
Cost per stop equals total route cost divided by completed stops.
Total route cost includes driver wages, fuel, vehicle depreciation, insurance, and software fees. Count only completed stops in the divisor. Failed attempts still cost money, so their cost stays in the total.
Track it by route, by driver, and by zone. Patterns show up quickly. One zone may cost twice as much as another.
Start With Route Optimization
Routing is where most savings sit. Delivery planning is a vehicle routing problem with time windows. It gets complex fast. Ten stops have over three million possible sequences. Twenty stops have more than two quintillion.
No dispatcher can compare that many options by hand. Habit and local knowledge work for small routes. They break down as volume grows.
Modern route optimization software uses heuristics to find near-best sequences in seconds. A solid tool accounts for:
- Customer time windows
- Vehicle capacity by weight and volume
- Driver shift limits and break rules
- Service time at each stop
- Live traffic and road restrictions
Feed the tool real data. Default service times are usually wrong. Measure actual time at apartments, offices, and loading docks. Update those numbers every month.
Cut Failed Deliveries
A failed attempt costs you twice. You pay for the wasted trip. Then you pay again for the redelivery. It also lowers stops per hour for that driver.
Most failures have simple causes. Bad addresses, absent customers, and blocked access lead the list. Fix them before the driver leaves the depot.
Validate and geocode addresses at order entry. Send a text the evening before with a two-hour window. Share a live tracking link on the day. Collect gate codes and access notes upfront. Capture a photo at drop-off as proof.
Match Vehicles and Loads to the Route
Right-size the fleet. A full-size van on a route of small parcels wastes fuel. A small van on bulky orders forces a second trip. Assign vehicles by cubic volume and stop density, not habit.
Load sequencing matters too. Load in reverse stop order. Drivers should never dig through the cargo area at the curb. Save two minutes on each of 80 stops and you gain over two hours per route.
Leave room for change. Same-day orders and cancellations happen. Keep a small capacity buffer and re-optimize mid-route when needed. Dynamic dispatch handles this better than a fixed plan.
Watch idle time as well. Telematics shows idling, harsh braking, and speeding by driver. Aggressive driving burns more fuel. Set idle limits and coach with data, not guesses.
Track the Metrics That Drive Margin
Review these weekly:
- Cost per stop
- Stops per driver hour
- First-attempt delivery rate
- Miles per stop
- On-time delivery rate
- Planned versus actual route time
Planned versus actual route time is the most useful of the six. A large gap means your plan does not match reality. Find out why. Traffic, parking, long service times, or poor sequencing usually explain it.
Price Delivery Based on Cost to Serve
Not every order costs the same. A dense urban drop costs far less than a rural one. Flat delivery fees hide that gap.
Use cost per stop by zone to set fees, minimum order values, and delivery days. Group low-density zones onto fixed days so routes fill up. Higher stop density lowers cost per stop.
Check customer profitability as well. A customer who orders small, often, and from far away may lose you money even at full price. Adjust minimums or fees to fix it.
Where to Start
Pick one route. Measure its cost per stop for two weeks. Run the same stops through an optimizer and compare the results. Apply what works to the rest of the fleet.
Small, measured changes build profit steadily. Review the numbers every week and keep adjusting.
