Case Studies

We genuinely believe that we can help you and your business, but don’t just take our word for it. Here are some case studies from our current roster of clients:

"Achieving a sustainable financial position has proved to be quite a challenge, but PORT have been extremely helpful.

In particular, we have worked closely with Ceris over recent years. He has guided us through a number of tricky periods and helped us to establish clear strategies and appropriate policies to ensure that our finances remain robust.

Ceris has provided us with a number of key insights that have enabled us to understand crucial elements of Caban’s finances. He is always available to answer any accounting or financial queries that crop up.

Our relationship with PORT is friendly, informal and relaxed, something which we feel facilitates transparent and constructive dialogue.

It’s important to trust your accountant and we certainly do with PORT.”

Mark Lynden - Finance Director, Caban Cyf.
