What it is
A confidentiality agreement, usually called an NDA, is the buyer's written promise about what it may do with what it learns: who the owner is, what the company earns, who its customers are, how the work runs. The buyer may use it to evaluate the purchase and for nothing else: not to recruit staff, not to call accounts, and not to mention in the industry that a sale is under consideration.
Why it matters
A company is sold while it keeps operating, and its value depends on no one knowing it is for sale. An employee who hears may begin looking elsewhere; a competitor who hears may begin calling customers. The process is therefore built so that the first document a buyer sees carries no name, and identifying detail moves only after the NDA is signed and the owner has approved the approach.
What it is not
- Not an offer. Signing commits the buyer to nothing except discretion. Most parties who sign will not buy, which is normal.
- Not exclusivity. Several buyers may hold signed agreements at once; that is the purpose. Exclusivity comes much later, in the letter of intent, and is a far larger decision.
- Not a substitute for judgement. It deters and it gives recourse; it does not make careless disclosure safe. Detail is therefore released in stages even after signature, matched to how serious the buyer has shown itself to be.
The useful signal
Serious buyers sign confidentiality agreements routinely and without objection. A buyer that resists signing one, negotiates it heavily, or asks for detail before it, has provided useful information early and at no cost.
Where this fits: the confidential outreach step, before any identifying detail moves. The vocabulary of the process is in the glossary.
