10 Contract Mistakes That Cost Businesses Thousands

Contracts are the backbone of business relationships, but they're often riddled with mistakes that can cost companies thousands—or even millions—of dollars. After working with hundreds of businesses, I've seen the same errors repeated over and over. Here are the 10 most common contract mistakes and how to avoid them.

1. Vague or Ambiguous Language

Using unclear language is one of the most common—and costly—contract mistakes. When terms like "reasonable," "promptly," or "as soon as possible" aren't clearly defined, they leave room for interpretation and disputes.

Solution: Define every term explicitly. Instead of "deliver promptly," say "deliver within 5 business days of order confirmation."

2. Missing Termination Clauses

Many contracts don't include clear termination clauses, leaving businesses stuck in unfavorable agreements with no exit strategy.

Solution: Always include termination clauses that specify how either party can end the agreement, including notice periods and conditions.

3. Failing to Update Old Contracts

Businesses often reuse old contract templates without updating them for new regulations, business models, or legal requirements. This can create serious compliance issues.

Solution: Review and update all contract templates annually, and consult legal counsel when business practices or regulations change.

4. Not Defining Payment Terms Clearly

Unclear payment terms lead to cash flow problems and disputes. When invoices are due, what happens if payment is late, and what payment methods are accepted?

Solution: Specify exact payment schedules, methods, late fees, and consequences for non-payment.

5. Overlooking Intellectual Property Rights

Who owns the work created under the contract? Many businesses lose valuable IP rights because their contracts don't address this issue.

Solution: Clearly state who owns intellectual property created during the contract term, including work products, inventions, and designs.

6. Missing Confidentiality Provisions

Without proper confidentiality clauses, your sensitive business information could be shared with competitors or the public.

Solution: Include robust confidentiality clauses (NDAs) that define what information is confidential and how long the obligation lasts.

7. Inadequate Dispute Resolution Procedures

When disputes arise—and they will—you need a clear process. Without one, you might end up in expensive litigation.

Solution: Include dispute resolution clauses that specify mediation, arbitration, or litigation procedures, as well as jurisdiction and venue.

8. Not Having the Right Signature Authority

A contract signed by someone without authority to bind the company may be unenforceable. This is especially common with large organizations.

Solution: Verify that signatories have the legal authority to bind their organizations. Require corporate resolutions if necessary.

9. Ignoring Regulatory Compliance

Industry-specific regulations (GDPR, HIPAA, etc.) require specific contract clauses. Missing these can result in fines and legal liability.

Solution: Ensure contracts comply with all applicable regulations. Consult legal experts familiar with your industry.

10. Failing to Keep Signed Copies

You'd be surprised how often businesses can't find signed contracts when disputes arise. Without proof of agreement, you have no recourse.

Solution: Use contract management software like DocuPro to store, organize, and retrieve signed contracts instantly.
