The article below explores the collaboration between four PrimeGlobal member firms - Thomas Westcott in the United Kingdom, Yzico in France, Auditia in Spain, and Walsh O’Brien Harnett in Ireland - who maximized their membership of PrimeGlobal to successfully collaborate on a £50 million project. 

This collaboration highlights the opportunities that PrimeGlobal membership brings for developing connections with your peers and increasing business opportunities. 


PrimeGlobal member firm Thomas Westcott were recently invited to tender for the audit of a £50 million manufacturing business with operations in France and Spain, in addition to the UK based Head Office.

The client was a subsidiary of a US parent and this was their first opportunity to seek external auditors outside of the ‘Big 4’ – a relationship which had previously been managed and coordinated by their parent company.

During the tender process, Thomas Westcott was able to demonstrate the strength they could bring as a member of PrimeGlobal via the opportunities for connection and collaboration membership of the association brings. The result was them winning the project and subsequently collaborating with PrimeGlobal member firms Yzico based in France and Auditia based in Spain.

Quite simply, without the strength of the association and its presence in France and Spain, it would not have been possible to win this new client. We were also able to introduce Irish PrimeGlobal member firm Walsh O’Brien Harnett, who have subsequently secured an audit of a related entity. In terms of how the collaboration has progressed, we have recently completed smooth and efficient stock counts at locations in both France and Spain, leveraging native speakers and local resource in a way that wouldn’t have been possible if we hadn’t worked together and tangibly brought together our collective strength as PrimeGlobal firms.
