Should you build or buy Last-Mile Delivery?
Last-mile delivery software handles the final leg of the delivery process — routing drivers, dispatching stops, optimizing sequences, capturing proof of delivery, communicating with recipients, and tracking packages from facility to doorstep. It covers both the dispatch management backend and the driver mobile app.
The build-vs-buy decision for last-mile delivery turns on how central delivery experience is to your customer value proposition and at what fleet scale the economics of custom routing logic justify the build investment over commercial per-driver pricing.
Build it, buy it, or bridge?
When building makes sense
Last-mile delivery has the most documented build precedent of any routing category. UPS built ORION. FedEx, Amazon, DoorDash, Instacart, and Veho all run proprietary dispatch and routing systems in production. VROOM and OSRM open-source solvers handle vehicle routing optimization at a level that matches most commercial platforms. For operations where delivery experience is the product — same-day, on-demand, or hyperlocal delivery — owning the routing model is a direct lever on the customer experience that drives retention. Your delivery territory, customer time window preferences, and geographic density patterns are specific enough that a custom model trained on your data will outperform generic vendor optimization. AI tooling has also lowered the entry point: teams can now build custom dispatch logic without implementing VRP algorithms from scratch, moving the realistic build conversation from large enterprise down to mid-market operators with genuinely complex routing constraints.
When buying makes sense
Below roughly 150 drivers, the per-driver pricing of commercial platforms like Onfleet and OptimoRoute makes buying dramatically cheaper than building. The $35-per-driver monthly fee covers not just route optimization but proof-of-delivery capture, customer notification workflows, and a driver mobile app — all components that need to be built and maintained in a custom system. Building a production-grade system with proper driver apps, POD workflows, and customer notifications runs $60,000 to $400,000 over 24 to 32 weeks, plus ongoing maintenance. AI hasn't changed that math for smaller fleets. Commercial platforms also handle the edge cases — weather disruptions, failed deliveries, substitute drop points — that are expensive to get right in a custom system. For standard delivery operations that aren't trying to differentiate on delivery experience itself, buying a proven commercial platform is the faster and more economical path.
The desk read
Last-mile delivery has the most real-world build precedent of any routing category. UPS built ORION. FedEx, Amazon, DoorDash, and Instacart all run proprietary dispatch and routing systems in production. The VROOM and OSRM open-source solvers handle vehicle routing optimization at a level that matches or exceeds most commercial platforms. For a company where delivery experience is the product, owning the routing model is a strategic question, with real cost implications underneath.
Buying makes sense below roughly 150 vehicles. The per-driver pricing of commercial platforms like Onfleet and OptimoRoute, around $35 per driver per month, is far cheaper than the $60,000 to $400,000 it takes to build a production-grade custom system with proper driver apps, proof-of-delivery capture, and customer notification workflows. AI hasn't changed that math much for smaller fleets. For larger or more complex operations, AI tooling has made the solver layer more accessible, letting teams build custom dispatch logic without implementing VRP algorithms from scratch. That moves the realistic starting point for a build conversation from large enterprise down to mid-market operators with genuinely complex routing constraints.
Frequently asked
What is Last-Mile Delivery software?
Last-mile delivery software handles the final leg of the delivery process — routing drivers, dispatching stops, optimizing sequences, capturing proof of delivery, communicating with recipients, and tracking packages from facility to doorstep. It covers both the dispatch management backend and the driver mobile app.
When does building Last-Mile Delivery software make sense?
Building makes sense for large fleets (150+ drivers) where delivery experience is the customer value proposition. Open-source solvers like VROOM and OSRM make the routing math accessible, and proprietary routing logic trained on your territory and customer patterns can meaningfully outperform generic commercial optimization.
When does buying Last-Mile Delivery software make sense?
Below roughly 150 drivers, buying wins on economics — $35/driver/month covers routing, proof-of-delivery, driver apps, and customer notifications, all of which need to be built and maintained in a custom system. Commercial platforms also handle delivery edge cases that are expensive to get right in custom builds.
What are the main Last-Mile Delivery vendors?
Representative vendors include Onfleet, Bringg, OptimoRoute, Route4Me. B4 Pro scores the full set.
What open-source tools are commonly used in custom last-mile delivery builds?
VROOM and OSRM are the most commonly used open-source VRP solvers for last-mile routing. OpenRouteService provides a routing API layer on top of OSRM. Teams pair these solvers with custom driver apps (often React Native) and notification infrastructure to build complete last-mile systems.
