We get to the bottom of it

We are 5Bar Assurance

Audit and accounting professionals who dare to dive deeper. Our audit and advisory services will enable you to safeguard your quality and minimise your risks.

We will help you to establish and enhance your integrity and credibility: the most crucial assets required for protecting and strengthening your brand reputation. We never leave the job half done; we get to the very bottom of things.

Almost non-auditor-like

We don’t shy away from responsibility, as it is our job to make a judgement and take a position. Shirking is not in our vocabulary; we take the initiative and lead the way. Our hands-on approach is unconventional and almost non-auditor-like.

We provide honest advice and practical tools, even when not asked for. Think of it as a full tank of oxygen that keeps you on track and ready for the future.

Our line-up

Your financial wellbeing is in safe hands with our diverse, international team. We offer the appropriate expertise, experience and people skills required to take you to the next level.
