A well-drafted B2B contract protects your company in two ways: it safeguards you against an unreliable counterparty and limits your risk if you fail to meet your own obligations. This guide covers practical mechanisms, including contractual penalties, guarantees, liability caps and arbitration clauses, and explains how to use them.
Each party’s liability: where to start
Before signing, define the scope of liability of each party in the contract. This is the foundation for pursuing claims.
What the contract must include
In every B2B contract, specify at least:
- Each party’s duties: who supplies what, and to what extent.
- Performance deadlines: dates or periods against which performance can be assessed.
- Quality standards: measurable acceptance criteria, not generalities.
- Consequences of failing to meet the terms: claims, penalties and the right to withdraw from the contract.
Principle: precision protects both parties
The more precise the contract wording, the less room there is for competing interpretations. State clearly which claims are available if an obligation is not performed or is performed improperly. At the same time, avoid making the contract unnecessarily long: address realistic scenarios, not hypothetical extremes.
Contractual penalties: when they apply and how to stipulate them
A contractual penalty is a term requiring a party to pay a specified amount for failing to perform, or improperly performing, a non-monetary obligation. It does not apply to non-payment or late payment; default interest addresses late payment.
What can a contractual penalty cover?
You have considerable flexibility. Contractual penalties most often cover:
- failure to deliver documents or products, such as completed software, on time;
- causing a leak of confidential information;
- breaching a non-compete obligation;
- failing to meet agreed quality standards.
How to write an effective contractual penalty clause
Avoid general wording such as: “Party A will pay Party B a contractual penalty for each breach of the contract.” That wording is defective because it does not identify the specific conduct that triggers the penalty.
Instead, use this rule:
If [specific act or omission], then [penalty in a specified amount].
Precise wording makes the penalty easier to pursue in court and makes the relationship more transparent: both parties know what to expect.
How to set the amount of a contractual penalty
The amount must be easy to calculate. In practice, there are two options:
- A fixed amount, for example PLN 5,000 for each day of culpable delay.
- A percentage of the contractual fee, for example 0.5% of the net contract value for each day of culpable delay.
If you choose a percentage, state expressly whether it is calculated on the gross or net amount. This can prevent a dispute before one arises.
Delay and culpable delay: a difference that changes liability
These two terms do not mean the same thing:
- Delay (opóźnienie): missing a deadline regardless of the reason. You are liable even if an external supplier is at fault.
- Culpable delay (zwłoka): missing a deadline through the obligated party’s fault. If the cause was beyond your control, you are not liable.
Check which term your contract uses. It determines whether you have to pay a penalty in a situation you could not control.
How to negotiate contractual penalties
It is not unusual for a contract to contain several penalties. Each party wants to protect its interests. If the penalties are one-sided and favor the counterparty, you have several options.
Caps on contractual liability
Set an aggregate maximum cap on the contractual penalties a party may have to pay, for example 20% of the net contractual fee. This is a compromise that most counterparties accept.
Reduce or remove selected penalties
If penalties clearly make the contract unbalanced, negotiate a reduction or deletion. A lack of balance is a sign that the terms are not a genuine partnership.
Damages above the contractual penalty
As a general rule, you cannot claim damages above the stipulated contractual penalty unless you include an appropriate clause in the contract. Such a clause allows you to claim the excess loss under general rules. This is standard in IT contracts; include it if actual loss may exceed the penalty.
Contractual guarantees: additional quality protection
Contractual penalties protect against non-performance, but they do not solve the problem of a defective product. A contractual guarantee is used for that.
What to know about a B2B guarantee
- Providing a guarantee is voluntary; no provision requires a counterparty to issue one.
- The guarantee rules are the same regardless of whether the parties are consumers or businesses.
- For a guarantee to apply, it must be stipulated in the contract.
What the guarantor may be required to do
The obligations of the party giving the guarantee may include:
- refunding the price paid;
- replacing the item with one free of defects;
- repairing the defective product;
- providing other repair or servicing work.
If the guarantee concerns the quality of a sold item, by default the guarantor is responsible for removing physical defects or supplying an item free of defects, within the time stated in the guarantee statement.
What to do: State the guarantee’s scope, duration and defect-reporting procedure in the contract. Omitting these terms can lead to disputes when a claim is made.
Arbitration clauses: resolving disputes faster
An arbitration clause sends potential disputes to an independent arbitrator or arbitration court instead of an ordinary court.
Why include one in the contract?
- Speed: arbitration takes considerably less time than proceedings in an ordinary court.
- Confidentiality: details of the dispute and its resolution do not become publicly available, helping protect your company’s reputation.
- Arbitrators’ expertise: decision-makers have experience in the relevant industry.
- International contracts: arbitration avoids the problem of differences between individual countries’ legal systems.
If you work with foreign counterparties or value discretion, an arbitration clause should be included in each of your contracts.
Checklist: what to include in a B2B contract to protect your position
Before signing, check that the contract includes:
- Each party’s duties, stated specifically, measurably and with deadlines.
- Contractual penalties set separately for each breach, with a clear amount or calculation method.
- An aggregate cap on contractual liability, setting the maximum penalty amount.
- A clause allowing damages above a contractual penalty, if actual loss could exceed it.
- A guarantee, including its scope, duration and defect-reporting procedure.
- An arbitration clause, or at least a mediation clause before court proceedings.
- A contract-update mechanism allowing renegotiation when legal or organizational conditions change.
A contract should evolve with the business relationship. Monitor performance and update the terms when the rules or scope of cooperation change. If you are unsure about specific wording, have a lawyer review the contract before signing. The cost of a review is many times lower than the cost of a dispute.
Frequently asked questions
How do I write an enforceable contractual penalty clause in a B2B contract? Use this rule: “if [specific act or omission], then [penalty in a specified amount].” Avoid general wording such as “a penalty for each breach of the contract”; it is defective because it does not identify the conduct that triggers the penalty. State the amount as a fixed sum, for example PLN 5,000 for each day of culpable delay, or as a percentage of the contractual fee, for example 0.5% of the net contract value for each day of culpable delay. If you use a percentage, state expressly whether it is based on the gross or net amount.
What is the difference between delay and culpable delay in a contract, and why does it matter for contractual penalties? Delay (opóźnienie) means missing a deadline regardless of the reason; you are liable even if an external supplier is at fault. Culpable delay (zwłoka) means missing a deadline through the obligated party’s fault; if the cause was beyond your control, you are not liable. Check which term your contract uses, because that determines whether you may have to pay a penalty for a situation you could not control.
Can I claim damages above a contractual penalty in a B2B contract? You cannot claim damages above the stipulated contractual penalty unless you include a clause allowing you to claim the excess loss under general rules. This is standard in IT contracts; include it if actual loss may exceed the penalty.
Why include a guarantee in a B2B contract if it already has contractual penalties? Contractual penalties protect against non-performance but do not address a defective product; a contractual guarantee is used for that. A guarantee may cover a refund, replacement with an item free of defects, repair or servicing. State its scope, duration and defect-reporting procedure in the contract, because omitting those terms can lead to disputes when a claim is made.
Why might an arbitration clause be preferable to an ordinary court in a B2B dispute? Arbitration takes considerably less time than proceedings in an ordinary court, details of the dispute and its resolution do not become publicly available, and arbitrators have industry experience. For international contracts, arbitration also avoids the problem of differences between countries’ legal systems.
