Mastering the Last Mile: 7 Delivery Challenges and How to Overcome Them

The biggest last-mile delivery challenges are inaccurate addresses, failed first attempts, high cost per drop, delays, poor visibility, rising customer expectations and environmental impact. The last mile, the final leg from your store or hub to the customer's door, is where all of them meet: every stop is a separate address, a separate time window and a separate chance for something to go wrong.

The good news is that each challenge has a practical fix, and most of them start with data you already have. Below, for each one: why it happens, what it costs, and how to overcome it.

What is last-mile delivery?

Last-mile delivery is the final step of fulfillment: getting an order from the place it was packed to the person who bought it. For parcel carriers it's one leg of a long journey. For a local merchant with its own drivers, it's usually the whole delivery: booking a slot, planning routes, driving, handing over the order and proving it arrived.

That's why the last mile shapes how customers feel about the whole purchase, and why small inefficiencies here show up as higher costs, missed windows and lost repeat orders.

1. Inaccurate address data

Why it happens: typos, missing apartment or gate numbers, new developments that map apps don't know yet, and addresses that are technically valid but point to the wrong entrance.

What it costs: a failed or late delivery, a second trip and a support conversation. Loqate's 2020 survey found that 8% of domestic first-time deliveries fail, costing retailers an average of $17.20 per order. Loqate (GBG), Fixing Failed Deliveries 2021 (Dec 2020), 2020 fieldwork

How to overcome it:

• Capture a map pin at checkout, not just a typed address.
• Send customers a pin-drop link so they can confirm their exact spot before dispatch.
• Geocode every order automatically so routes start from real coordinates.
• Flag orders where the pin and the typed address disagree, before a driver finds out at the curb.

In ScrollEngine, map-pin capture at checkout, a pin-drop link and automatic geocoding (on your own Google Maps Platform key) are live, and address-mismatch flags ◐ Early access warn you when a pin is far from the typed address.

2. Failed first attempts

Why it happens: nobody is home, the building is locked, or the driver arrives outside the time the customer expected.

What it costs: a second trip at your expense, and often the customer. According to AlixPartners' 2026 Home Delivery Survey, 52% of shoppers will stop buying from a retailer after just one or two missed deliveries. AlixPartners, 2026 Home Delivery Survey (Jun 2026)

How to overcome it:

• Let customers choose a delivery date and time slot at checkout, so they plan to be there.
• Send "on the way" and arrival updates, so they know when to expect the driver.
• Capture photo and signature proof of delivery, so "it never arrived" disputes are settled with evidence.
• Offer store pickup for customers who can't be home.

ScrollEngine's date and slot calendar handles cutoffs, prep time, blackout dates and per-location time zones, and the driver app records photo, signature and notes as proof of delivery.

3. High cost per drop

Why it happens: each stop is a single order at a single address. Backtracking, idle time, half-empty vehicles and short trips all land on that one order.

What it costs: margin. According to AlixPartners' 2026 Home Delivery Survey, 64% of retail supply-chain executives say home delivery is not as profitable as in-store sales. AlixPartners, 2026 Home Delivery Survey (Jun 2026)

How to overcome it:

• Use route optimization to sequence stops and plan all drivers together, within vehicle capacity.
• Set delivery zones and rates by order value or weight, with minimum orders where they make sense.
• Group nearby orders into one trip where you can.
• Offer store pickup as a lower-cost option.

ScrollEngine plans optimized routes for multiple drivers with capacity, time windows, shifts and breaks, and batching nearby orders into one trip ◐ Early access helps cut trips further. For the full cost-and-speed playbook, read Shopify route optimization: cut fuel and speed deliveries.

4. Delivery delays

Why it happens: traffic, road closures, late loading, overbooked slots and plans that assumed a perfect day.

What it costs: trust, quickly. According to AlixPartners' 2026 Home Delivery Survey, nearly 90% of shoppers say a late delivery weakens or ends their relationship with the retailer, even after an apology. AlixPartners, 2026 Home Delivery Survey (via Mondaq) (Jun 2026)

How to overcome it:

• Set realistic cutoffs and prep time, so orders aren't promised before they can be packed.
• Cap each slot by what your drivers can deliver.
• Plan routes with traffic in mind.
• Edit routes after they start when something changes, instead of leaving drivers to improvise.
• Get an alert before a delivery runs late, not after.

In ScrollEngine, routes stay editable after they start and ETAs are recalculated, and at-risk alerts flag a delivery that is getting close to its deadline. When several routes need rebalancing at once, see our bulk route editing tips.

5. Lack of visibility and tracking

Why it happens: once a van leaves, many operations lose sight of it, and customers are left guessing.

What it costs: support time. DigitalGenius customer data from 2023 shows that around one in five e-commerce support queries asks "Where is my order?", rising to up to 40% at peak (vendor data). DigitalGenius, What is a normal WISMO rate (Mar 2023), vendor data

How to overcome it:

• Give dispatchers a live map of every driver and delivery.
• Give customers a tracking page with the driver's status and a live ETA.
• Send updates on the channel each customer uses.
• Detect arrivals automatically, so status doesn't depend on a driver remembering to tap a button.

ScrollEngine's live driver map runs in the standalone web dashboard, and customers get a branded tracking page plus email, SMS and WhatsApp updates. Read why arrival visibility matters in last-mile delivery.

6. Rising customer expectations

Why it happens: shoppers compare every delivery with the fastest, clearest one they've ever had.

What it costs: repeat purchases. According to AlixPartners' 2026 Home Delivery Survey, more than 85% of consumers say a poor delivery experience reduces their willingness to buy again. AlixPartners, 2026 Home Delivery Survey (via Mondaq) (Jun 2026)

How to overcome it:

• Show customers at checkout exactly what you can deliver to their address, and when.
• Offer same-day or next-day slots only where your drivers can keep them.
• Make store pickup a first-class option, with pickup slots and a "ready for pickup" message.
• Make rescheduling easy for your support team.

ScrollEngine offers delivery and pickup slots with daily and per-slot capacity, a pickup workflow with ready-for-pickup notifications, and delivery rescheduling on admin and draft orders.

7. Environmental impact

Why it happens: empty miles, idling, and many small trips in dense areas.

What it costs: fuel, emissions and money. Cutting the number of trips is one of the biggest levers, and pickup is one way to do it. World Economic Forum modelling suggests pickup-point networks can reduce delivery trips by 15% and congestion by 2% (2024, modelled scenario). World Economic Forum with Accenture, Transforming Urban Logistics (2024), modelled scenario

How to overcome it:

• Cut miles with route optimization and fewer failed attempts.
• Consolidate deliveries by area, and group nearby orders into one trip.
• Match the vehicle to the job: electric vans or cargo bikes for dense areas.
• Encourage store pickup where customers are nearby anyway.

In ScrollEngine, optimized routes and booked delivery windows cut empty miles and repeat trips, store pickup removes a delivery trip for customers who are nearby anyway, and the vehicle and fleet registry in the standalone web dashboard records each vehicle you run, including electric ones, with its payload.

Last-mile challenges at a glance

Challenge	Typical cause	First fix
Inaccurate addresses	Typed addresses, no map pin	Map pin at checkout and a pin-drop link
Failed first attempts	Nobody home, wrong time	Booked delivery windows and arrival updates
High cost per drop	Backtracking, empty space, short trips	Route optimization across all drivers
Delays	Traffic, overbooked slots, rigid plans	Realistic cutoffs, slot caps, live route edits

Rising expectations	Comparison with the fastest delivery	Clear promises at checkout, pickup as an option
Environmental impact	Empty miles, many small trips	Fewer miles, grouped orders, right-sized vehicles

Where to start

You don't have to fix everything at once. In order of effort:

1. Fix addresses first. It is usually the least expensive fix, and it prevents failed trips at the source.
2. Sell windows you can keep. Delivery slots with capacity limits turn guesswork into a plan.
3. Optimize routes. Plan all drivers together, within shifts and vehicle capacity.
4. Turn on tracking and updates. Fewer customers call when they can see the van coming.
5. Measure. Track failed attempts, on-time rate and miles per stop every week.

Conclusion

The last mile doesn't have to be the hardest mile. Exact locations, delivery windows you can keep, optimized routes and live tracking turn it from a cost you put up with into a reason customers come back.

ScrollEngine's local delivery app for Shopify brings those pieces together: delivery and pickup slots at checkout, route optimization for your drivers, a driver app with proof of delivery, and live tracking for your customers.
