Three common commercial contract mistakes

Commercial contracts can have a significant impact on a business’s profitability, operations and risk exposure. 

Yet many business owners sign vendor agreements, service contracts and sales agreements without fully understanding key provisions or appreciating how those terms may affect them down the road. 

What appears to be a routine business contract can create unexpected obligations, financial exposure or costly disputes if important details are overlooked.

Fortunately, many contract-related issues stem from a few common mistakes that can often be identified and addressed before an agreement is signed. 

By paying close attention to scope, termination rights and liability provisions, businesses can better protect their interests and avoid unpleasant surprises.

The most common commercial contract mistakes

Mistake #1: Scope lacks a clear definition

A common and costly commercial contract mistake is failing to clearly define the scope of work.

When the scope is vague or open to multiple interpretations, each party may enter the relationship with different assumptions and expectations, creating a recipe for conflict.

For example, a contract may require a vendor to provide “marketing support,” “IT services” or “consulting services” without specifying exactly what those services include, leaving room for disagreement about deliverables, timelines and performance expectations.

Mistake #2: Termination, exit clauses are overlooked

Businesses often devote considerable effort to negotiating the start of a deal while paying far less attention to how the relationship may end. 

As a result, termination, renewal and exit provisions are frequently overlooked.

This oversight can lead to significant operational and financial consequences long after the agreement is signed, including:

• Auto-renewal clauses quietly extending a contract without notice
• Expensive early termination fees, or absence of early termination rights
• One-sided provisions that allow a party to unilaterally terminate at any time while the other has no recourse
• Agreements that initially seemed attractive but turn into unplanned and unwanted long-term commitments

Mistake #3: Failing to review liability, indemnity provisions

Liability and indemnity clauses determine who is responsible when something goes wrong, but many business owners skim these sections because the language feels dense or overly technical. 

They’re not wrong, but this is risky.

Some contracts impose unlimited liability, meaning there is no cap on what you might owe.

Others contain one-sided indemnity clauses, requiring one party to cover the other’s losses – even when both contributed. 

Some agreements even make you responsible for losses beyond your control, leading to unexpected costs.

How to avoid common contract mistakes

1. Define deliverables, expectations clearly

A clear, detailed description of the scope of work is one of the best ways to prevent disputes and to ensure both parties know their responsibilities. 

A well-defined scope should clearly outline each party’s responsibilities, timelines, performance standards and approval processes. 

It should also include schedules or exhibits that detail timelines, deliverables, pricing and instructions. 

The more specific and measurable the obligations, the easier it is to hold both parties accountable and avoid disputes.

2. Understand your exit rights

Understanding the exit strategy can be just as important as understanding the deal itself. 

Before signing, make sure you understand notice requirements, renewal mechanics and termination conditions and rights. 

Understanding how a contract ends can help you avoid being trapped in a costly or restrictive contract.

3. Negotiate fair allocation of risk 

Review liability and indemnity provisions carefully, ideally with legal guidance. 

Make sure the contract’s allocation of risk aligns with your business objectives and risk tolerance. 

Where appropriate, negotiate liability caps tied to the contract’s value and mutual indemnity provisions to create a more balanced allocation of risk between the parties.

Consider which party is more likely to incur liability, as well as which party is more likely to benefit from any particular provision.

Key takeaways for business owners

Commercial contracts do more than document a deal – they define rights and responsibilities, and they allocate risk. 

Investing in careful contract review, especially for complex or high-stakes agreements, can help ensure the contract supports your business objectives while minimizing unwanted surprises. 

By identifying hidden risks and addressing problematic provisions before execution, businesses can reduce risk and help avoid some costly disputes before the ink on the contract has dried.
