Business plans, pricing, customer lists, trade secrets — information shared in the course of a business relationship needs a contractual obligation to stay there. Without one, it's legally shareable.
Free. No registration. No card. No catch.
What it means
A confidentiality clause — also called an NDA provision when it's a standalone agreement — creates a contractual obligation for the recipient of confidential information to keep it secret and use it only for the purposes of the engagement. It defines what counts as confidential, how long the obligation lasts, and what the exclusions are.
The confidentiality clause says: "Information you receive about my business in connection with this project is secret. You can use it for this project only. You can't share it with others, use it for other purposes, or disclose it after the project ends." Both parties typically have obligations.
Any engagement where either party shares sensitive business information: financial data, pricing, client lists, product plans, strategies, trade secrets, or proprietary processes. Also: when a client shares their data and you need to protect yourself from liability if it leaks.
Without a confidentiality clause, there is no legal obligation to protect information shared in the course of the engagement. Information a client shares with their contractor can be shared with the contractor's other clients, used for the contractor's own purposes, or disclosed publicly.
Why it's missed
Why missed
Many businesses sign a standalone NDA before discussions, then forget to include confidentiality terms in the actual service contract. A separate NDA and a contract clause can have different definitions and durations — which creates gaps.
Why missed
"We're just doing a logo" — but the client shared their go-to-market strategy in the brief. That's confidential information, and now you have no obligation to protect it. The size of the engagement doesn't determine the sensitivity of the information shared.
Why missed
Business owners assume they need to protect the client's information, but not vice versa. The contractor's pricing, methods, and processes are also confidential. Mutual confidentiality protects both parties.
What can go wrong
A contractor shares a client's pricing model with a competitor — not maliciously, just in conversation. Without a confidentiality obligation, there's no breach of contract, only potentially a trade secret misappropriation claim, which is much harder to prove.
A contractor handles customer data. Without confidentiality and data handling terms, if that data leaks, the contractor has no contractual limitation on their liability. The client can claim the full value of the breach.
A contractor publishes client work publicly before launch. The client's product is revealed ahead of their announcement. No confidentiality clause, no breach of contract. The client's competitive advantage is gone.
The client shares the contractor's proprietary methods, pricing, or processes with a competitor. Without mutual confidentiality, there's no contractual obligation on the client's side either.
Red-flag wording
These formulations appear in many contracts. Each one has a gap that disclosure walks through.
Red flag
Requires the disclosing party to physically mark every document. Sensitive information shared verbally, via email, or in a meeting is not protected. In practice, nothing gets marked.
Red flag
The obligation expires when the project ends. Trade secrets and business information don't lose their sensitivity at project completion. Post-termination confidentiality is essential.
Red flag
Who authorized whom? Without a definition of authorized parties, this phrase is unenforceable. The other party can authorize their entire team and anyone they do business with.
Red flag
"Best efforts" is a low bar and a high dispute. It invites argument about what effort was reasonable. Use "shall not disclose" — an absolute obligation — not a best-efforts qualifier.
Safer pattern
A strong confidentiality clause defines confidential information broadly (not just marked documents), specifies the permitted uses, limits disclosure to need-to-know personnel, survives termination for a defined period, and carves out standard exclusions like information already public or independently developed.
BizDraft includes mutual confidentiality terms in every service agreement, with post-termination duration calibrated to the sensitivity of the engagement type.
