When you need an independent audit view

There are specific moments when the standard statutory audit is not enough — when you need someone with no pre-existing relationship to look at the numbers and tell you what they actually see.

⚖️

Auditor conflict of interest

Your current auditor also prepares your accounts, advises on tax, and has worked with the same management team for years. Independence is compromised. A second opinion gives you an objective assessment.

📈

M&A due diligence

Buying a Swiss company? The vendor's accounts may flatter the true picture. An independent review of the financial statements, accounting policies, and tax positions protects you before you sign.

💰

Investor pressure

Your investor or board requires confirmation that the accounts fairly represent the company's position before releasing funds or approving a distribution.

🔎

Suspected accounting errors

Management suspects the books contain errors, mis-classifications, or that provisions are incorrectly stated. An independent review identifies and quantifies the issues.

🔄

Change of auditor

You want to change your statutory auditor. Before the transition, you want an independent firm to review the prior year accounts and flag any issues the outgoing auditor may have missed.

🏛

Bank facility review

Your bank has requested a reviewed or audited set of accounts before approving a credit facility or renewing an existing one. We deliver within your timeline.

Audit and review services

From statutory compliance to targeted due diligence — each engagement has a fixed scope, a fixed fee, and a fixed delivery date.

From first contact to written report

Four steps — scope agreed upfront, findings stated plainly, no surprises at the end.

01

Scope definition

We agree exactly what you need: statutory audit, second opinion, or due diligence. Scope is fixed in a written engagement letter before any work begins.

02

Document review

We request the accounts, working papers (where the auditor provides them), general ledger, and supporting documents. All information treated with strict confidentiality.

03

Independent assessment

We perform our procedures independently of the prior auditor. Our findings are evidence-based and stated plainly — we do not soften conclusions to protect relationships.

04

Written report

You receive a clear written report within the agreed timeline. If issues are found, we recommend specific remediation steps.

Fixed fees — agreed before we start

No hourly billing, no open-ended engagements. You know the cost before we begin and we hold to it.

"We were buying a Zürich distribution company and the vendor's accounts had several unusual items our lawyers flagged. The due diligence review found CHF 400'000 of overstated inventory that we used to renegotiate the price. Money very well spent."

Audit & second opinion — your questions

A limited audit (eingeschränkte Revision) involves analytical procedures and targeted testing. It is sufficient for most Swiss SMEs. An ordinary audit (ordentliche Revision) involves a more rigorous examination and is required for companies that exceed two of: CHF 20M revenue, CHF 10M balance sheet, 50 full-time employees — or that have more than 250 employees, or are publicly listed.
Yes. You can engage any RAB-registered auditor to review the prior auditor's conclusions. The second auditor will form an independent view based on the available evidence. We provide written second opinions and state our conclusions plainly — including when we agree with the original auditor.
A limited audit for a straightforward Swiss company typically takes two to three weeks from receipt of complete documentation. Ordinary audits take four to six weeks. We agree a specific completion date at the outset and hold to it.
RAB (Revisionsaufsichtsbehörde) is the Swiss Federal Audit Oversight Authority. Only RAB-registered auditors may issue statutory audit opinions for Swiss companies. Our auditors are RAB-registered, which means our audit opinions are legally valid for Swiss commercial register purposes.
Our core expertise is Swiss statutory accounting and GAAP. We perform financial due diligence on Swiss targets (Swiss OR, Swiss tax) for both domestic and international acquirers. For targets in other jurisdictions, we work with our network of international firms.
