Serving as a managing director is often associated primarily with business opportunities, strategic management, and company growth. Less attention is paid to the fact that the role also carries personal liability. Experience shows that the greatest risks rarely arise from a single major mistake. More often, they result from underestimating seemingly routine situations. Below is an overview of the ten most common mistakes we encounter in practice and which can have serious consequences for both managing directors and the companies they lead.
Operating through a limited liability company is often associated with the assumption that a managing director’s personal assets are safely separated from business risks. In reality, however, the situation is not that straightforward.
Although a managing director is generally not liable for every company debt simply because of holding office, they are responsible for how the company is managed and whether they perform their duties with due care. This means acting with the necessary loyalty, expertise, and diligence required of a prudent businessperson.
In practice, the greatest problems seldom arise from particularly bold business decisions. Much more frequently, they stem from seemingly minor issues. Over time, these “operational details” can develop into disputes involving claims for damages worth millions.
The duty of due care does not mean that a managing director must always choose the most profitable option. Business inherently involves risk. However, a director must be able to demonstrate that decisions were made on an informed basis, in good faith, and in the company's best interests. The Czech Supreme Court has repeatedly emphasized that liability is assessed not only by the outcome of a decision, but primarily by the process followed when the decision was made.
So which mistakes are most commonly repeated in practice?
Managing directors often need to make decisions quickly. However, this does not mean decisions can be made purely on intuition and without adequate information.
A fundamental aspect of the duty of due care is the obligation to make decisions based on a sufficiently established factual basis. For example, when the company is considering a significant investment, the acquisition of a competitor, or entry into a new market, the managing director should have access to appropriate economic analyses, financial data, and professional advice.
Good documentation is not unnecessary bureaucracy. It is one of the most effective forms of protection available to a managing director.
The company begins paying its obligations late, invoice payment terms are repeatedly extended, and operations are financed through new advances or short-term funding. Nevertheless, management continues to rely on a future contract, loan, or investor without having a concrete and realistic recovery plan.
A managing director must continuously monitor the company’s financial position and respond to early warning signs. If the company becomes insolvent, a statutory obligation arises to file for insolvency without undue delay. Failure to do so may result in liability towards creditors.
Timely action does not necessarily mean the immediate end of the business. There may still be opportunities to negotiate with banks and key creditors, restructure financing, sell non-essential assets, or use preventive restructuring tools. The biggest mistake is often inaction and the belief that the situation will resolve itself.
Transactions between a company and its managing director, shareholder, family member, or another related entity are not automatically prohibited. However, they always involve heightened risk.
A common issue is the failure to disclose a conflict of interest or the lack of evidence demonstrating that the agreed terms are consistent with market conditions. The lease of property owned by a managing director, a consulting agreement with a family-owned business, or intra-group asset transfers should therefore be handled transparently and properly documented.
In practice, some managing directors accept the role only formally. The company is effectively managed by another director, a shareholder, a chief financial officer, or an external adviser, while the formal director has little or no involvement in actual management.
This arrangement is highly risky. Certain tasks may be delegated, but responsibility for overall supervision cannot. A managing director does not have to review every invoice, but should maintain oversight of key commercial and financial matters, require regular reporting, and react to unusual transactions or warning signals.
Unfavourable contractual terms often become apparent only when the company wishes to terminate an agreement, pursue a claim, or defend itself against penalties. By then, it may be too late to discover that the contract contains unlimited liability provisions, one-sided penalties, automatic renewals, or difficult-to-meet guarantees.
Multi-million losses do not arise solely from poor business decisions. They are often caused by poorly drafted contractual documentation. Compared to the potential losses involved, the cost of a legal review is usually negligible.
GDPR, whistleblower protection, anti-money laundering (AML) requirements, sanctions compliance, cybersecurity regulations, and consumer protection rules are sometimes viewed merely as mandatory policies stored in a shared folder.
However, a formally adopted policy will not protect a company if it does not reflect actual business processes and employees do not follow it in practice.
A managing director should understand which regulatory requirements genuinely apply to the company, who is responsible for them, and whether compliance controls are reviewed regularly. Beyond regulatory fines, non-compliance may result in the loss of key customers, reputational damage, and substantial remediation costs.
Many managing directors focus on winning new business and maintaining customer relationships but devote less attention to collecting outstanding receivables.
Business relationships are important, and immediate litigation is not always the best solution. Problems arise, however, when a company tolerates long-term non-payment, continues providing goods or services to unreliable customers, or allows receivables to become time-barred.
A managing director is not required to pursue every outstanding amount at all costs. However, decisions must be commercially rational. Instalment agreements, settlements, or temporary payment deferrals may be in the company’s interests if supported by a realistic assessment of collectability and commercial benefits.
Effective receivables management requires clear ageing reports, a defined escalation process, and regular monitoring of high-risk debtors.
An external accountant may maintain the company’s books, but cannot assume responsibility for managing the company or replace management’s understanding of how the business operates.
Accountants can only work with the information they receive. They may not be aware of all commercial arrangements, business risks, or circumstances with financial implications. If the managing director does not actively cooperate with the accounting function, important matters may be overlooked even when the accountant performs their role professionally and diligently.
Managing directors should understand key financial indicators, monitor revenue, costs, receivables, liabilities, and cash flow, and actively seek clarification where necessary. Repeated warnings about missing documentation, accounting inconsistencies, overdue liabilities, or potential tax risks should never be ignored.
High-quality accounting is not a one-sided process. It is the result of open communication between management and accountants. Financial reporting is therefore not merely a legal requirement but one of the most important tools available to directors for informed decision-making and early identification of emerging risks.
A managing director may find themselves in a situation where their personal interests, the interests of a shareholder, or the interests of another group company conflict with those of the company they represent. It is not sufficient to rely on the fact that “everyone knows about it.”
Conflicts of interest should be disclosed promptly, documented in writing, and resolved transparently. Proper records protect not only the company but also the managing director. They provide evidence that the conflict was not concealed and that it was handled appropriately.
The failure of a critical system, the sudden loss of a major customer, the departure of a key employee, or even the temporary incapacity of a managing director can seriously disrupt business operations within days. Yet many companies continue to assume they will address a crisis only when it occurs.
A crisis management plan does not need to be lengthy. However, it should identify responsible persons, succession arrangements, access to critical data, communication protocols, and procedures for the most likely crisis scenarios. When a crisis strikes, predefined contacts and decision-making authority can prevent a substantial portion of the resulting damage.
Today, the role of a managing director extends far beyond simply running a business. Statutory directors are expected to actively oversee risks, make informed decisions, ensure transparency, and respond effectively to an increasingly complex regulatory environment.
The good news is that most risks can be significantly reduced. Experience shows that the most effective protection is not avoiding business risk altogether, but establishing a system that demonstrates that all material decisions were made on an informed basis, with loyalty, diligence, and in the best interests of the company.
An equally important aspect of risk prevention is a director’s willingness to seek professional advice at the right time. Legal, tax, accounting, and transaction advisers do not replace the responsibilities of corporate officers, but they can help identify risks, evaluate available options, and provide the information needed for sound decision-making. In practice, a long-term and trusted relationship with professional advisers often proves to be not merely a cost, but a valuable investment in protecting both the company and its management.
