The Challenge

Understanding the problem

The business needed to promise convenient delivery slots without exceeding limited vehicle capacity or losing control of fresh-product batches and expiry dates.

Capacity-constrained slots

Multiple orders could compete for the same fixed delivery window and service area.

Fresh-product controls

Expiry dates, batches, and weight-based pricing needed to remain part of the order flow.

Complex delivery planning

Routes, status updates, proof of delivery, and customer expectations had to stay connected.

The Solution

What Justo built

Justo built an online ordering and delivery system that validated capacity before confirming slots and connected fulfilment with the customer delivery journey.

Capacity-aware booking

Vehicle availability was checked before a delivery slot was confirmed.

Product traceability

The workflow handled expiry dates, batches, and weight-based pricing.

Driver operations

Routes, delivery status, and proof of delivery were managed in the same system.

Customer visibility

Customers could track delivery progress and receive an estimated arrival time.

How We Built It
