Case Study
An ordering and delivery platform that balanced customer time slots with vehicle capacity, fresh-product controls, and route execution.

The Challenge
The business needed to promise convenient delivery slots without exceeding limited vehicle capacity or losing control of fresh-product batches and expiry dates.
Multiple orders could compete for the same fixed delivery window and service area.
Expiry dates, batches, and weight-based pricing needed to remain part of the order flow.
Routes, status updates, proof of delivery, and customer expectations had to stay connected.
The Solution
Justo built an online ordering and delivery system that validated capacity before confirming slots and connected fulfilment with the customer delivery journey.
Vehicle availability was checked before a delivery slot was confirmed.
The workflow handled expiry dates, batches, and weight-based pricing.
Routes, delivery status, and proof of delivery were managed in the same system.
Customers could track delivery progress and receive an estimated arrival time.
How We Built It

The ordering flow connects slot capacity, product controls, route planning, driver updates, and customer notifications through one shared delivery record.
The system was structured around the constraints of regional delivery areas, vehicle capacity, and perishable inventory.
The Results
Delivery mileage and fuel consumption were reduced by 25%, while on-time delivery reached 98.5%.
