Retail & supply chain specialists.

“We inspire and support retailers to solve complex business issues, realising significant and sustainable bottom-line profit improvements.” 


Retail & Supply Chain just got better.

We are performance improvement specialists with backgrounds spanning the end to end supply chain. As subject matter experts we understand how to add value and engage with others because “we have been there”. We believe in being supportive from beginning through to final transformation.

We are team players, there to “catch a fall”, not “catch you out”.

Not ALL consultants are the same…

Our areas of expertise include:

Buying and Sourcing

Good buying is often instinctive, great products, excellent prices and reliable suppliers. We can help to strengthen your buying processes and provide the tools to improve product sourcing and build your range proposition to drive sales and profit.

Duty and Importing

This specialist area requires real expertise to protect your business. We can help you put in place the import systems, duty management processes and even carry out a forensic analysis of your duty payments to identify and recover any overpaid duty.

Supply Chain

Modern supply chains can be complex, we all know that. We can help with all aspects of supply chain development and improvement, from optimising supplier-to-shelf processes, to increasing efficiency, and speed within the supply chain.

Logistics and Distribution

All organisations are looking for more from their logistics operations and at a lower cost. We can help increase DC efficiency and capacity whilst identifying operational inefficiencies and removing waste labour costs.

Retail Operations

Retail is detail, execution and compliance is often overlooked when reviewing and developing store operations. We are passionate about retailing, driving store growth, reducing costs and delivering great service.

Store Planning

Store environments and layouts differentiate your brand and products by creating a meaningful customer experience. We believe in always working back from the customer to develop the most profitable and customer centric store propositions.
