Most buyers treat the non-compete as boilerplate that the lawyers handle in the last week. That is the wrong week. The seller knows your customers by first name, knows which of your technicians could run a branch, and knows what the business is worth to a competitor. If the seller can open across town six months after closing, you did not buy a business. You bought a head start for a rival.
The non-compete is also not only a legal document. It sets the tone for the whole seller relationship, and it is felt for years inside the integration. Start with the planning in the pre-close checklist and seller transition plan, then settle these terms on purpose.
What a non-compete actually protects
It protects three things you paid for: the customer relationships, the people, and the know-how. A good one covers all three, not just the first. A seller who agrees not to compete but is free to hire your best estimator has found the loophole on day one.
Enforceability depends on your state, the length, the geography, and how narrowly the restriction is drawn. I am not your lawyer and neither is this page. What I can tell you is that a narrow, reasonable restriction that a court will uphold beats an aggressive one that gets thrown out. Ask counsel to draft for what will hold, not for what sounds toughest.
Scope: what the seller cannot do
Write the business lines down. If you bought the commercial HVAC service side and the seller keeps a small residential installation shop, say so in the document, in plain words. Vague scope is where disputes start.
Geography should match where the business actually sells and services, not where you wish it did.
Duration: how long is long enough
Long enough that the customers and the people have moved their loyalty to you and the business, and not so long that the seller refuses to sign or a court trims it. The honest test is how long it takes for the seller's relationships to transfer. If the top accounts are still calling the seller after two years, the restriction should reach past that.
Tie the clock to a start date you can prove: closing, or the end of the seller's consulting period. Decide which you mean, and write it down.
Who else should sign
The seller is rarely the only person who can take the customers. Family members in the business, a partner who cashed out, and a loyal general manager can all carry the book of business to a competitor. Think about who touches the customer relationships and who holds the technical knowledge.
Non-competes for people who are not selling are a different conversation, and often a different instrument. A key employee who gets no money at closing has little reason to sign a restriction. Pair it with real retention, a role, or equity, or do not ask. See employee retention after acquisition for how I think about holding the people who hold the business.
How the other deal terms change the answer
If part of the price is paid over time, the non-compete and the payment terms are linked. A seller who is still owed money has a reason to behave. A seller who has been paid in full at closing has less. And if there is an earn-out, the seller may argue that your integration decisions are cutting into their payout and so the restriction should loosen. Read why an earn-out hurts integration before you finalize either one.
The restriction also interacts with how long the seller stays on. A seller working inside the company for a defined period is not competing. A seller who leaves in month three has months of restriction ahead and plenty of time to resent it. For the right length of the transition, see how long the seller should stay after closing. I would rather have a narrow restriction that holds than a broad one that gets struck down.
Decision table: set the terms before you sign
Work down the questions with counsel in the room. Each row tells you where the answer sends you.
| Question | If yes, it points to | If no, it points to |
|---|---|---|
| Do customers buy because of the seller personally? | Longer restriction, tied to the end of the transition period | Shorter restriction, tied to closing |
| Does the seller keep any related business or property? | Carve it out by name in the scope, and restrict adjacent lines | Keep scope to the lines you bought |
| Can family or partners reach the same customers? | Have them sign a matching restriction or a non-solicit | Seller alone is enough |
| Is part of the price paid over time? | Link the restriction to payment, and write what happens on default | Add a non-solicit of staff and customers as a backstop |
| Does a key employee hold the technical know-how? | Offer a role or retention in exchange for a narrow restriction | Do not ask for one you cannot enforce |
| Did counsel confirm the draft will hold in your state? | Sign | Narrow the scope, geography, or length until it will |
What I would not do
I would not bury the non-compete in the last draft. A seller who feels ambushed at the table does the minimum afterward. Put the terms in the first conversation and explain the reason.
The best protection for the customers is a transition where the seller introduces you and hands the relationships over in person. The document is the backstop.

Questions
How long should a seller non-compete last after a business sale?
There is no fixed answer, and what a court will enforce varies by state. In practice it should run long enough for the customer relationships and the key people to move their loyalty to you, and many buyers measure from the end of the seller's transition period rather than from closing. Ask counsel what will hold where you operate, and keep the scope narrow enough to survive review.
Is a non-compete the same as a non-solicit?
No. A non-compete restricts the seller from running a competing business. A non-solicit restricts them from approaching your customers or employees, even if they work elsewhere. Many deals use both, and a non-solicit is often easier to enforce because it is narrower.
Can I ask employees who are not selling to sign a non-compete?
You can ask, but a person who receives nothing for signing has little reason to agree, and some states limit these agreements for employees. Pair any request with a real role, pay, or equity, and check with counsel before you ask.
What if the seller refuses to sign one?
Treat the refusal as information. Either the price needs to reflect the risk, the scope needs to narrow, or the transition needs to be built so the relationships transfer before the seller leaves. A seller who will not agree to any restriction is telling you something about their plans.
