Financial loss: the core risk in advisory work
General liability insurance thinks in terms of bodily injury and property damage: a visitor trips in your office, an employee breaks a client’s device. If you sell expertise, however, the damage usually looks different. The client loses money although nobody was hurt and nothing was broken. This is known as pure financial loss, and standard general liability policies usually do not cover it.
A typical case: a management consultant recommends a software solution after incomplete analysis, and it turns out to be unsuitable. Unwinding the project and switching systems costs the client a six-figure sum, which the client claims from the consultant under the Swiss rules on mandates (Art. 398 CO). Without professional liability cover, the consultant pays the damages and legal fees personally or from the company’s funds.
Professional liability covers the risk that sits in your actual service, not just the risk of running a business.
Who needs professional liability cover
The cover matters for anyone who gives recommendations based on expertise, produces calculations, brokers contracts or manages assets on behalf of others. Company size is largely irrelevant: the size of a potential claim depends on the mandate, not on your headcount.
- Management consulting, fiduciary services, auditing and tax advice
- Architecture and engineering firms, site management and specialist planning
- IT service providers, software development and systems integration
- Financial service providers, asset managers, insurance and credit brokers
- Law firms, real estate agents, marketing and communications agencies
When it is mandatory
For some professions, cover is required by law or by the regulator. Lawyers entered in a cantonal register must show professional liability insurance of at least CHF 1 million under the Federal Act on the Free Movement of Lawyers (BGFA). Requirements for insurance or financial guarantees also apply to independent insurance intermediaries and to certain financial service providers and asset managers. Your professional association or the competent supervisor can tell you whether and at what level your profession is affected. For everyone else, the cover is voluntary, but clients increasingly require it in their contracts.
What is covered and what is not
A good professional liability policy does two things: it pays justified claims and defends you against unjustified ones. This defence function is often underestimated. In fee disputes, clients not infrequently threaten damages. The insurer then examines liability and covers the defence costs, even if nothing is owed in the end.
| Field | Typical mistake | Possible consequence |
|---|---|---|
| Management consulting | Incomplete analysis | Extra costs for the wrong solution |
| Fiduciary services | Incorrect booking or missed deadline | Back taxes, default interest |
| Insurance advice | Insufficient cover recommended | Client’s loss remains uninsured |
| IT services | Faulty software implementation | Business interruption, data loss |
| Architecture and engineering | Planning or calculation error | Remedial work, construction delays |
Depending on the product, further modules can be added: gross negligence, loss of third-party documents, damage caused by dishonest employees, or infringement of personality and intellectual property rights. Commonly excluded are intentional damage, contractual guarantees that go beyond statutory liability, and fines or penalties.
How to read the policy
Whether you are protected in a real case depends less on the premium comparison than on a handful of clauses. Clarify the following points in writing before you sign.
- Claims-made basis: cover usually applies to claims raised during the policy period. Ask for retroactive cover for errors made before the policy started, and for run-off cover for claims made after it ends, for example when you close the business.
- Sum insured: it must match your largest realistic mandate, not the average one. Check whether the limit applies per claim or per year and whether defence costs are included.
- Described activity: only what is written in the policy is insured. If you expand your services, the cover must be adjusted.
- Deductible: a higher deductible lowers the premium but hits every claim.
- Territorial scope: work for clients abroad often comes with restrictions, particularly for the USA and Canada.
Tip for the self-employed
Report any complaint that sounds like a potential claim to your insurer immediately, and before you admit any mistake yourself. A premature concession to the client can put your cover at risk.
Typical gaps and mistakes
- Taking out general liability only and assuming advisory errors are included.
- Leaving the sum insured unchanged for years although mandates have grown.
- Creating a gap when switching insurers, because old errors are covered by neither the old nor the new contract.
- Promising liability or guarantees in client contracts that the policy does not cover.
- Using freelancers or subcontractors without checking whether their mistakes are covered.
Alongside the insurance, review your own contracts. A clear scope of work, documented assumptions and a legally permissible limitation of liability reduce the risk before the insurance is ever needed. A legal specialist is the right person to draft such clauses.
