What is the last mile, really?
That’s the question Eddie Misicka, VP of Product at OneRail, opened with during his session at the Trimble Insight Tech Conference — and it sparked a deeper conversation about the complexity and nuance that define today’s logistics landscape.
“Somebody’s last mile is somebody else’s first mile or middle mile.”
Depending on where you sit in the supply chain (shipper, 3PL, retailer or carrier), your definition of last mile may look entirely different. For some, it’s parcel delivery to a customer’s doorstep. For others, it’s a B2B shipment from warehouse to storefront. It might even be inter-facility movement or on-demand fleet augmentation to fill capacity gaps.
That’s the problem. The final mile is often treated like a monolith, but it’s anything but. It’s fragmented, high-stakes and responsible for up to 60% of total supply chain costs (as Misicka pointed out during his presentation). But for many organizations, it remains the most misunderstood and under-optimized part of the journey.
At OneRail, we’ve built our entire platform around solving that chaos. And in this session, Misicka shared the formula for doing exactly that: elastic capacity, AI-powered orchestration and complete visibility.
The Real Cost of the Final Mile
When we talk about supply chain optimization, it’s easy to focus on upstream efficiencies like better forecasting, smarter warehousing and leaner inventory. But the true cost center is further downstream.
According to Misicka, 50-60% of total supply chain cost is incurred in the final mile — a staggering number when you consider that the last leg is often the shortest in distance but the most unpredictable in execution.
Why is the last mile so expensive? It boils down to fragmentation and complexity. Unlike linehaul or facility-to-facility moves, last mile delivery relies on a vast, disjointed network of carriers that can include national parcel giants, regional couriers and independent contractors. Each brings its own set of systems, rate cards, service levels and coverage gaps.
This naturally leads to inconsistent technology, wildly variable costs and limited visibility. One delivery might go smoothly with real-time tracking, while the next is riddled with delays, missed ETAs or service failures — and there’s no unified system to manage it all.
Without a scalable, intelligent way to manage the last mile, businesses risk both profit erosion and customer loss.
Top Constraints Facing Shippers Today
During his presentation, Misicka explored the constraints that face today’s shippers, limiting agility and driving up costs. Here’s a look at the five most prominent last mile constraints.
1. Fixed Fleets, Inflexible Capacity
Many businesses rely on internal fleets to control delivery quality, but with fixed assets come fixed limits. Trucks break down, drivers call out and rigidity becomes a liability when demand surges.
If capacity can’t flex in real time, shippers are forced to either overbuild (and eat the cost) or underdeliver (and damage customer trust). Fleet augmentation is essential, but it must be fast, scalable and on-demand to truly add value.
2. Parcel Network Overload & Rising Costs
Parcel carriers have long been the backbone of last mile delivery, but their networks weren’t designed for today’s expectations. Predictability has given way to capacity constraints and rate hikes, with limited flexibility for dynamic SLAs or service differentiation.
Shippers are increasingly seeking alternatives to protect margins and ensure delivery quality, especially as parcel surcharges and accessorial fees continue to climb.
3. Seasonal Demand Spikes
Demand isn’t linear. It ebbs and flows with retail cycles, regional weather and promotional calendars. Whether it’s holiday gifting or spring garden season, these spikes can overwhelm fixed fleets and static routing plans.
Without elastic capacity that scales up and down without long-term commitments, shippers are left scrambling — often at the expense of on-time performance and customer satisfaction.
4. High Customer Expectations
The Amazon Effect is no longer a theory. It’s real, and it’s become the baseline for shippers. End customers expect fast, accurate, visible deliveries as a standard. Whether it’s B2B or B2C, late arrivals, missed time windows, or lack of tracking erode trust instantly.
Today’s fulfillment strategies must be built around real-time visibility and proactive communication rather than solely speed.
5. Unreliable Delivery Performance
The final mile is fraught with exceptions like wrong addresses, missed docks and no-show drivers. When things go wrong, they snowball fast.
Misicka emphasized the importance of having human-backed exception management in place. Technology alone can’t solve an unresponsive driver or an unclear delivery location. Without live support to resolve in-the-moment issues, even the best routing plans can fall apart.
Together, these constraints underscore the need for a new model that blends technology, network scale and operational agility to meet the realities of today’s logistics environment.
The Elastic Capacity Advantage
When delivery demand spikes, most shippers are left with two unappealing options: Scramble to source carriers at inflated spot rates, or risk delayed shipments and damaged relationships. But what if capacity could flex on demand — without expanding your fleet or renegotiating contracts?
That’s the promise of OneRail’s elastic delivery network.
By tapping into a vast, mode-agnostic ecosystem (from bike couriers in dense urban zones to flatbeds with Moffetts for heavy freight), OneRail gives shippers instant access to nationwide delivery capacity. It’s all powered by a single integration, unified under a flat-rate model that eliminates the unpredictability of ad hoc carrier sourcing.
Need an LTL run tomorrow and a courier in 2 hours? Done — no new procurement workflows required.
This on-demand capacity model means shippers can scale up or down instantly to meet fluctuating needs without the fixed costs of maintaining a large internal fleet.
“If you could scale that instant capacity without buying more trucks — that’s where your business itself is going to scale,” Misicka said in his presentation.
It’s true fleet augmentation, built for the real world of demand surges, geographic expansion and seasonal swings.
Take, for example, a national home improvement retailer. While most of the industry plans for a holiday spike in Q4, this retailer’s biggest surge hits in the spring, when customers begin landscaping projects and order bulk materials like mulch and decking supplies. With OneRail, they’re able to activate additional capacity instantly without overcommitting to trucks they don’t need year-round.
This level of scalability, reliability and cost control is what makes elastic capacity a competitive advantage.
AI-Powered Orchestration: From Chaos to Control
The final mile is fast-moving and full of variables. Traffic, weather, customer availability and inventory location can impact which carrier, route and delivery mode is best for any given shipment. Managing this complexity manually or across siloed systems is nearly impossible at scale.
That’s where OneRail’s AI-powered orchestration platform becomes invaluable.
At the heart of OneRail’s technology is an intelligent decision engine that automates what once required teams of dispatchers, spreadsheets and guesswork. It dynamically selects the optimal delivery mode, carrier and route in real time, based on cost, SLA, location, asset type and delivery window.
“We have some really cool software,” Misicka said during his presentation. “It’s AI-powered orchestration that makes decisions, and it’s mode-agnostic.”
And it doesn’t stop at routing. OneRail’s platform continuously drives automated cost optimization, choosing not just the fastest or cheapest path, but the most cost-effective mode for every order, based on your business rules and current market conditions.
All of this happens within a centralized system that connects to OneRail’s massive carrier network, eliminating the need for shippers to manage dozens of individual carrier relationships, integrations and rate cards. Shippers can achieve the scale and reach they need with just one platform, one API and one rate card.
Layered on top is real-time tracking and proactive exception management, giving both shippers and their customers visibility into every delivery — with live support to step in when the unexpected happens.
This infrastructure helps shippers create a smarter, faster and more resilient last mile. This approach to final mile delivery scales with your business, adapts in real time and delights the end customer — all without adding operational burden.
Results That Scale: Satisfied Customers, Expanded Markets
OneRail’s customer base spans every corner of the supply chain, from enterprise retailers to nimble 3PLs.
Some leverage the platform for B2B fulfillment, moving product between facilities or delivering to business customers on a recurring schedule. Others focus on B2C, using OneRail to reach consumers with fast, trackable home deliveries. Many do both — and rely on fleet augmentation to flexibly scale capacity in real time, without expanding their internal assets.
OneRail creates value through operational efficiency and by unlocking strategic growth.
