Audit Services

Audit and assurance services in Ireland that go beyond compliance

In addition to being a regulatory requirement, audit plays a vital role in maintaining the credibility of your business and provides directors with an important business control. Our audit approach is designed to meet compliance requirements while also adding real value for your management team.

We work closely with directors and finance teams in Ireland and internationally, building strong relationships and delivering a practical, well-managed audit process.

Our clients operate across multiple sectors, including property and construction, eCommerce and retail, manufacturing, pharmaceutical, professional services, and hospitality. We are also the trusted auditor in Ireland to many multinational brands. 

Led by Managing Partner, Stephen Connolly, and our experienced team of accountants, we provide a partner-led service with continuity of staff and a collaborative approach that ensures open matters are closed efficiently and deadlines are met.

“The team at CAS are a huge support to O’HareTEP. We’ve been steadily growing over the past few years and that’s partially down to my ability to focus on business growth, while CAS Advisory looks after all my accounts, tax, payroll, and audit. They’ve been particularly valuable in helping me navigate the purchase of equipment from various locations across Europe - they’re genuine experts. I’d highly recommend CAS.”
