Data as an asset when you sell your business

Company data goes with the business in a stock sale and goes only where the agreement says in an asset sale. Either way, three things decide what you can do with it: what you promised customers and employees, what the buyer wants and pays for, and what you must keep for tax and legal reasons after closing. Treat records as a line in the deal, not an afterthought.

Stock sale vs asset sale

	Stock (or membership interest) sale	Asset sale
What transfers	The whole company, including all its records and contracts	Only the assets listed in the agreement
Customer data	Stays with the company the buyer now owns	Transfers only if listed, and only as your privacy promises allow
Records the buyer does not want	Buyer’s problem	Stay with the seller entity
Your obligations after closing	Mostly the buyer’s	You still keep tax, payroll and employment records

Privacy promises travel with the data

If your privacy policy told customers their information would not be shared or sold, a transfer can break that promise. Many policies include a clause allowing transfer in a merger or sale; check yours. In bankruptcy, the Bankruptcy Code makes this explicit: under 11 U.S.C. § 363(b)(1), customer personal information covered by a no-transfer policy can only be sold consistently with the policy or with court approval after a consumer privacy ombudsman reviews it. Outside bankruptcy there is no ombudsman, but the promise still binds you.

Due diligence will ask about data

Expect questions on:

• what personal data you hold, about whom, and under which privacy notices;
• security incidents and how they were handled;
• customer contracts with data clauses;
• who owns the software and content the company uses;
• any licence of company data you have granted.

Prepare a short data map: systems, years of history, categories of personal data, and the policy that applied.

Licensing data before or alongside a sale

Some owners license de-identified copies of company records to AI developers. Before a sale this needs care: in a stock sale the buyer inherits the licence; in an asset sale the buyer may want the same data. Done openly, it can be a separate source of value, especially for records the buyer does not plan to use, such as years of old email and tickets. Disclose it and agree it in the deal.

After closing

Keep what you must. The IRS says most tax records should be kept for three years, employment tax records for at least four, and some for seven. If the selling entity is dissolved after the sale, its records still need a home; see how to dissolve an LLC or corporation.
