What people say

  • “Our operation is highly complex involving VMI, Forecasting of Customer demand requirements, JIT deliveries leaving aside all the complexities and complications of the products that we manage. Principal Logistics Technologies have been integral to our operation & supply chain now for over 10 years. Our companies have grown significantly during that period and we still enjoy a great working relationship and I’m sure that this will continue into the future”.
  • “We recently acquired a site Allied Logistics where the In-DEX WMS suite of products has successfully managed the complex needs of the site for well over a decade. All the management team and staff there were full of praise for the system and support. I was impressed with the application, and my initial meetings with the Principal Logistics Technologies team. I look forward to enhancing the system capabilities on this site here in the coming years”.

  • “Given the margins that operate within our industry I have always held the view that IT strategy should be central to competitive advantage in driving efficiencies and reducing costs. The In-DEX WMS suite of products enables us to achieve this from electronically communicating with our customers, reducing administration and costly errors to dual cycling of forklifts. Principal Logistics Technologies knowing this, have continually knocked on the door with ideas, and are quick to up take ideas that we have brought to the table. I’d highly recommend both the solutions and the company”.
