  • 5 Common Mistakes in Commercial Contracts – How you can legally avoid them
In this article, I explain 5 of the most common mistakes found in commercial contracts – and what you can do to avoid them.

Commercial contracts are the backbone of any business. They set clear rules, prevent conflicts and provide a solid legal basis for long-term collaborations. However, many entrepreneurs treat contracts as mere formalities, which often leads to financial losses, legal disputes or business blockages. Common mistakes in commercial contracts include unclear language, inadequate scope of work descriptions, failure to specify governing law, and inadequate dispute resolution clauses. How you can legally avoid them? Read this!

1. Lack of penalty clauses – when the other party is late or does not perform

Problem: Many contracts completely omit the mention of penalties in case of delay or non-performance. Without these clauses, it is difficult to prove and quantify the damage in court.
Solution: Include a clear penalty clause (% of the contract value per day of delay, fixed amount, etc.) for each important obligation. This will discourage the trading partner from violating the contractual terms.

2. Ambiguous or undefined obligations – confusion leads to conflict

Ambiguous or undefined obligations can indeed lead to conflict. When roles, responsibilities, or contractual terms are unclear, it creates confusion and uncertainty, which can result in misunderstandings, disagreements, and ultimately, disputes. This is especially true in high-conflict situations where emotions are already heightened. 
Problem: General wording such as “the supply of goods will be ensured” or “timely delivery will be made” can lead to different interpretations, and in court, ambiguity backfires against the drafter of the contract.
Solution: Define clearly and concretely:

– What is being delivered (quantity, quality, exact deadline);
– Who is responsible for transportation, installation, support, etc.;
– What are the conditions for acceptance or return?

3. Lack of a clear termination clause

Problem: If the partner seriously breaches the contract and there is no termination clause, it is difficult to legally terminate the collaboration without costs or lawsuits.
Solution: Include a unilateral termination clause, which allows the termination of the contractual relationship under specific conditions (e.g. non-payment, defective delivery, force majeure). Also mention the notification procedure.

4. Absent confidentiality clauses – your ideas can be used against you

Problema: În multe cazuri, partenerii comerciali intră în posesia unor informații sensibile (strategii, prețuri, rețete, contacte) fără ca acestea să fie protejate legal.
Soluție: Adaugă o clauză de confidențialitate în care se specifică:

– What information is confidential;
– Sanctions in case of disclosure.
– The period of confidentiality;

5. Failure to indicate the competent court – where is the dispute heard?

Problem: If your partner is from another county or abroad and you have not established a competent court, the lawsuit will be heard where the defendant is domiciled – which can mean additional costs and loss of time.
Solution: Include a jurisdiction clause (e.g. “the parties agree that any dispute will be resolved by the competent courts in Bucharest”) or an arbitration clause, if you prefer a faster and more confidential resolution.

Advice: The contract is the shield of your business – build it thoroughly

Frequently Asked Questions

Do you offer online consultancy?
Yes. Many clients outside Bucharest or in the diaspora prefer online advice. We can schedule a video, telephone or e-mail meeting, depending on the complexity of the case.
How to make your contracts both transparent and flexible?
As your business grows, your contracts should keep up. A well-drafted agreement will eliminate ambiguity, reduce any potential disputes, and facilitate your growth and scalability. To achieve this, your contracts should:

- Use plain language: Your contracts don't need to read like a 19th-century legal document. Use plain language that both parties can understand. Instead of 'hereby agrees to provide services by the specifications set forth in Appendix A,'try' we will provide the services described in Schedule A.' This clarity helps build trust and speeds up the signing process.
- Allow for growth: Your business will evolve, and your contracts should be ready for that growth. Include provisions that allow for reasonable adjustments as your business scales. For example, if you're offering a software service, ensure your contract allows you to update features or modify your service as technology advances.
- Balance protection with customer needs: Protect your interests without overburdening your customers, striking the right balance is key to fostering strong relationships.
What are the must-have clauses in a commercial contract?
Every contract should be tailored to the specific details of your agreement or relationship, but certain standard clauses are essential. Think of these as the fundamental building blocks of your contract:

- Parties involved: Clearly define who is agreeing.
- Scope of services or products: Outline precisely what is being provided.
- Payment terms: Specify pricing, payment calculations, due dates, and consequences for late payment.
- Liability limitations: Establish clear boundaries for financial and legal responsibility.
- Confidentiality: Protect sensitive business and customer information.
- Termination rights: Define the conditions under which the contract can be terminated.
- Dispute resolution: Establish a straightforward process for handling disagreements.
*Some of these may be included as an appendix or schedule rather than the main body of the agreement (for example, the method of calculating payments).
Must contracts be in writing, or are verbal agreements enough?
While contracts don't always need to be in writing legally, verbal agreements or even implied actions can suffice. Written contracts, however, offer clarity, minimise misunderstandings, and simplify enforcement. For start-ups, having clear, well-documented agreements is essential for preventing disputes and protecting business interests. Putting it in writing provides a solid reference point and reduces the risk of 'he said, she said' scenarios.
How do you set fair limits on liabilities in contracts?
Fundamental to every business contract is how it assigns the risk from key issues, and how a well-crafted liability clause can be your safety net. But here’s the challenge – go too far in limiting liability, and you might scare off potential customers. Instead, aim for a fair and practical approach by:

- Setting realistic financial limits: Define a cap that protects your business without alarming clients.
- Clarifying responsibilities: Outline what happens in the event of a service disruption or failure.
- Ensuring fairness: Customers want protection, too, so strike a balance that benefits both sides.
For businesses that provide ongoing services, Service Level Agreements (SLAs) play a key role in setting clear performance expectations and remedies, helping manage customer concerns.

Liability clauses are often heavily negotiated because they define:

- Financial risk exposure: Setting caps to prevent excessive losses.
- Exclusions & limitations: Clarifying which damages are covered (or not).
Legal clarity: Preventing disputes before they happen.
- Suppliers typically push to limit liability, while customers demand stronger protections. Finding the proper middle ground is essential for both trust and commercial success. Given the complexity, legal advice can be a game-changer in ensuring your contracts protect your business without killing the deal.
How do you solve contract disputes without going to court?
Even with solid contracts, disputes can still pop up. The key is to handle them efficiently before they spiral into expensive litigation. A well-crafted dispute resolution clause in your contract can save you time, money, and stress. Here’s how:

- Mediation: Keep it civil. A neutral third party helps negotiate a solution before the situation escalates.
- Arbitration: A legally binding alternative to court that’s often faster and more cost-effective.
- Jurisdiction clauses: Decide upfront which country’s laws will govern your contract, thereby avoiding potential cross-border disputes.
By proactively defining how you’ll resolve disputes, you can cut down on legal costs and avoid lengthy courtroom battles. Alternative dispute resolution (ADR) methods, such as mediation and arbitration, are more innovative, faster, and far less stressful than litigation.

The bottom line? Plan, protect your business, and minimise legal headaches.
