Multi-Site Delivery and Stock Application

The business problem

What was going wrong

Ordering stock across several sites was running on phone calls, text messages and spreadsheets. Nobody could see what had been ordered against what had arrived, approvals happened verbally, and reconciling deliveries against invoices at month end meant going back through messages.

The solution

What we proposed

One application with three views of the same data: sites raise and track orders, drivers work a delivery run and capture proof at the door, and administrators approve, adjust and reconcile. Point of sale product data feeds the catalogue so the ordering list matches what the sites actually sell, and scheduled reports go out without anyone assembling them.
