You can buy the business and still lose its biggest customer — if that contract wouldn't come with it.

Buyers often assume that when they acquire a business, everything it relies on comes along — its contracts, its lease, its licenses. Frequently that assumption is wrong. Many agreements contain clauses restricting assignment or triggering on a change of control, and many licenses and permits require regulatory consent to transfer. Miss one, and you can close the deal only to find you’ve lost a key customer contract, your premises, or the legal right to operate. This guide explains how contract and license transfer actually works and how to protect it.

You can buy the business and still lose its biggest customer.

Why transfer isn't automatic

Whether contracts and licenses come with a business depends heavily on deal structure and on the specific agreements. In a stock or equity purchase, the entity is unchanged, so its contracts generally continue — though some contain change-of-control clauses that treat the sale as a triggering event. In an asset purchase, contracts must usually be individually assigned, and many contain anti-assignment provisions. The Small Business Administration’s guidance on sba.gov reflects how central these operating relationships are. The point is that transfer cannot be assumed; it must be verified agreement by agreement.

The deal structure decides whether contracts follow automatically — or need consent.

Anti-assignment and change-of-control clauses

Two clause types most often complicate transfer. Anti-assignment clauses prohibit assigning a contract without the other party’s consent, and are common in customer, vendor, and lease agreements — so a buyer may need that party’s sign-off to keep the relationship. Change-of-control clauses treat a sale of the business as an event that can require consent or even allow termination, and they can catch even stock deals where contracts otherwise transfer automatically. Identifying these clauses during due diligence is what tells you which relationships are at risk and which consents you must secure.

Licenses, permits, and regulatory consent

Beyond private contracts, a business often depends on government-issued licenses and permits to operate legally, and these frequently do not transfer with a sale. Depending on the industry and jurisdiction, the buyer may need to obtain regulatory consent, apply for reissuance, or qualify anew. The sba.gov resource highlights how essential proper licensing is to lawful operation. Discovering after closing that a critical license didn’t transfer — and can’t be quickly replaced — can halt the business. Confirming transferability and starting the process before closing is essential.

Securing consents before closing

The practical answer is to make consent a condition of the deal. During diligence, catalog every material contract and license, flag those requiring consent to assign or survive a change of control, and build obtaining those consents into the closing checklist — often as a closing condition. Some consents take time or negotiation, so starting early matters. Handled this way, the transfer becomes a managed process rather than a post-closing scramble, and the business you operate the day after closing has the contracts, leases, and licenses it needs to keep running.
