Trazzo for Ground LogisticsTrazzo for Ground Logistics:last-mile route optimization
The last mile is where the OTIF you promised evaporates: the dispatcher's spreadsheet can't see the low-emission zone, the end customer doesn't answer and the POD shows up on paper the next day. Trazzo builds the route, runs it and proves it: dynamic dispatch, a delivery window coordinated on WhatsApp and digital proof of delivery with photo, signature and GPS.
How do you optimize last-mile delivery routes?
Last-mile routes are optimized by connecting an AI optimization engine to the orders in your TMS or ERP: the engine accounts for delivery windows, capacity per vehicle and urban circulation restrictions (low-emission zones, nighttime downtown restrictions, color-coded permits), plus the weight and volume of the load, real-time traffic and estimated unloading time, and generates the route sheets in minutes. Then it runs them: the driver gets the route in an app, the end customer confirms their window on WhatsApp and every stop closes with digital proof of delivery validated against the delivery note.
In Ground Logistics this matters twice as much because the last mile is where the trip is won or lost: the shipment leaves the DC on time but arrives late for lack of coordination with the receiver's window, every redelivery costs a large share of what the first delivery is worth, and major retailers penalize low OTIF. Trazzo, the last-mile agent in the Vantegrate Suite, was built for that stretch: it plans, dispatches, re-optimizes when something unexpected happens and leaves the digital evidence that releases the invoice.
The full picture of the sector (all five agents applied to carriers, 3PLs, fulfillment providers, urban distributors and fleet managers) is on the Ground Logistics and Transportation page.
The pain points of last-mile ground delivery
We gathered them in dozens of conversations with carriers, 3PLs, fulfillment operators and urban distributors across the sector's nine sub-verticals.
Planning is done in a spreadsheet
Planners build route sheets by hand and planning takes hours before the first truck leaves. Out on the street, the driver ends up deciding the order of the stops.
Every redelivery eats into the margin
First attempt delivery stays low because nobody coordinated the window with the receiver, and every redelivery costs a large share of what the first delivery is worth.
The customer calls to ask where the order is
With no tracking, end customers call customer service asking about their order. The desk fills up with calls that a live link would have prevented.
The POD arrives on paper the next day
The invoice isn't released until the proof is loaded, and when a delivery is disputed there's no digital proof to back the operation. Every dispute is a trip in doubt.
How Trazzo solves it in ground transportation
The agent's capabilities, mapped to the sector's pain points: each one runs on your TMS, your fleet and your real restrictions, not on a map with dots.
No spreadsheet
AI routes with real urban restrictions
Generates route sheets in minutes, accounting for windows, capacity per vehicle, traffic and low-emission zones, nighttime downtown restrictions and color-coded permits: the restrictions a traditional route planner ignores.
Redeliveries
Delivery window coordinated with the end customer
Sends a 2-to-4-hour window on WhatsApp, lets the customer confirm or reschedule in the chat and gives a heads-up 30 minutes before arrival. The receiver is there when the truck pulls up.
Calls
Live tracking with no app
The end customer gets a shared link without installing anything, with an updated ETA, the vehicle's location and the driver's name. Tracking calls die down on their own.
Disputes
Digital POD validated against the delivery note
Photo of the delivered product, electronic signature, geolocation and timestamp, with detection of quantity or condition discrepancies at the moment of unloading. The invoice releases itself.
The unexpected
Dynamic re-optimization on the fly
A broken-down vehicle, a road closure or an absent customer: Trazzo works out which unit absorbs the delivery or reschedules with the customer in real time, without rebuilding the plan by hand.
Empty miles
Multi-customer consolidation and cross-docking
Loads with nearby destinations are coordinated on the same route sheet, and breaking down intercity freight is planned automatically: fewer empty miles, tolls and fuel per delivery.
A morning on a 3PL's last mile
The full flow with the sector's typical operation: an e-commerce 3PL that moves thousands of orders a day across Buenos Aires and its metro area.
5:10 AM
The day's orders come down from the WMS
Confirmed orders flow into Trazzo from the system. Before, a team of planners spent hours building route sheets in a spreadsheet; now the first truck doesn't wait for anyone.
5:25 AM
Routes are generated in minutes
The engine assigns the fleet and builds each run accounting for windows, weight, volume, urban circulation restrictions and traffic. The planner supervises exceptions instead of loading routes.
8:30 AM
The end customer confirms the window
Each receiver gets a 2-to-4-hour window on WhatsApp with the option to reschedule. One moves it to the afternoon and the route rearranges itself, with no calls and no manual replanning.
11:40 AM
A van breaks down mid-route
Trazzo detects the delay, checks the available fleet and reassigns the pending deliveries to the nearest unit with capacity. The rest of the route sheet stays intact.
1:15 PM
Every delivery closes with a digital POD
Photo of the package, electronic signature, geolocation and validation against the delivery note on the spot. If there's a quantity or condition discrepancy, the alert goes out instantly, not three days later.
The day closes with more deliveries made on the first attempt, the end customer informed without calling anyone and invoices released the same day thanks to the digital POD. The planning that used to take up a whole team's early morning now takes minutes, supervised by exception.

Public industry benchmarks, not our own results: every Trazzo implementation is measured against a baseline agreed with the customer (first attempt delivery, cost per delivery, empty miles, last-mile OTIF).
Secure AI agents that work with your data
Trazzo handles customer addresses, routes and proofs of delivery: operational data no CISO hands over lightly. That's why it runs 100% on Salesforce and Oracle Cloud Infrastructure, with those platforms' SOC 2 Type II and ISO 27001 certifications and the permissions you define. We don't claim anyone else's certifications: Vantegrate enables, the customer operates and certifies.
Frequently asked questions about Trazzo for Ground Logistics
How much can a route optimizer cut costs?
How much can a route optimizer cut costs?
Public industry benchmarks put the savings at 5% to 25% less distance driven, and effective route optimization can reduce delivery costs by around 25% (Routific; Solera). The real result depends on your starting point: how much redeliveries weigh on the operation, how many empty miles the fleet carries and how manual planning is. That's why every Trazzo implementation starts by measuring a baseline agreed with the customer and is evaluated against that number, not against the benchmark.
What is digital proof of delivery (POD) and what does it include?
What is digital proof of delivery (POD) and what does it include?
It's the digital record that replaces the paper delivery note: a photo of the delivered product, the receiver's electronic signature, geolocation and timestamp, all in a single record. In B2B deliveries it adds the signed delivery note or the customer's stamp, and Trazzo validates the unloading against the delivery note and the transport order to catch quantity or condition discrepancies on the spot. The most concrete operational effect: the invoice releases itself when the delivery is confirmed, instead of waiting for the next day's paperwork.
Does Trazzo account for low-emission zones, nighttime downtown restrictions and color-coded permits?
Does Trazzo account for low-emission zones, nighttime downtown restrictions and color-coded permits?
Yes. The engine accounts for Low-Emission Zones (Buenos Aires, Bogotá, Mexico City, São Paulo and others), restrictions by neighborhood or thoroughfare such as the downtown core, nighttime restrictions, weight and size limits by street and color-coded permits where they apply. Each restriction is loaded into the model and updated as regulations change, which is exactly what a traditional route planner and a spreadsheet can't keep up with.
Should you build your own routing engine or use Trazzo?
Should you build your own routing engine or use Trazzo?
Building it only makes sense if routing is the heart of your product. A serious engine solves an optimization problem with time windows, capacities, urban restrictions and live re-optimization, and it takes a dedicated team to keep it current with every regulatory change and every edge case on the street. Trazzo comes implemented turnkey and integrated with your TMS or ERP, with a driver app, WhatsApp coordination and digital POD included: the operation transforms in weeks, not on an in-house engineering roadmap. The integration model is on the product page.
