Buy-Sell Agreement vs. Operating Agreement: Why You Need Both
Your operating agreement governs how the business runs day to day. A buy-sell agreement governs what happens when an owner leaves, dies, or becomes disabled. They solve different problems — and you need both.
"I already have an operating agreement—isn't that enough?"
It's the most common question we hear from business owners, and the answer is almost always no. Your operating agreement and a buy-sell agreement solve completely different problems. One runs the business. The other protects it when ownership changes. Confusing the two—or assuming one covers both—is how businesses end up in litigation after a partner dies or walks away.
What Each Document Does
An operating agreement is your business's internal rulebook. It covers governance, voting rights, profit distribution, management structure, and day-to-day operations. It answers: How do we run this business together?
A buy-sell agreement is a contract that governs ownership transitions. It covers what happens when someone leaves—whether through death, disability, retirement, divorce, or voluntary departure. It answers: What happens when one of us is no longer here?
These documents are complementary, not redundant. The operating agreement assumes all current owners will keep operating. The buy-sell agreement plans for the moment that assumption breaks down.
Side-by-Side Comparison
| Topic | Operating Agreement | Buy-Sell Agreement |
|---|---|---|
| Purpose | Governs how the business operates | Governs what happens when ownership changes |
| What it governs | Voting, management, profit splits, roles | Buyout mechanics, transfer of ownership interests |
| Triggering events | Not event-driven; always in effect | Death, disability, retirement, divorce, voluntary exit, bankruptcy |
| Valuation provisions | Rarely addressed or vaguely referenced | Specific method: fixed price, formula, appraisal, or hybrid |
| Funding mechanism | Not addressed | Insurance-funded, installment terms, or other specified sources |
| Who it protects | All members in their roles as operators | Departing members (or their estates) and remaining owners |
| When it matters most | Every day the business is running | The day someone leaves, dies, or becomes disabled |
| How often updated | When membership or structure changes | Annually, plus after any major business event |
| Transfer restrictions | Basic consent requirements | Detailed mandatory buyout terms and timelines |
| Payment terms | Not addressed | Lump sum vs. installments, interest rates, deadlines |
Where Operating Agreements Fall Short
Most operating agreements include a few paragraphs about transferring ownership interests. Typically, they say something like "members cannot transfer their interest without the consent of the other members." That's a good start, but it's not a plan.
Here's what the operating agreement almost never addresses:
- A specific valuation method. "Fair market value" is meaningless without a defined process for determining it. Who decides? By what formula? Based on what financials?
- A funding mechanism. Even if the remaining owners are required to buy out a departing member, the operating agreement doesn't say where the money comes from.
- Disability triggers. What qualifies as a disability? How long does someone have to be unable to work before a buyout is triggered? Who makes that determination?
- Divorce protections. If a member's ex-spouse is awarded part of their ownership interest, how do the other members prevent an unwanted new partner?
- Detailed buyout timelines. How quickly does the buyout need to happen? Is there a notice period? What are the consequences if the buying party misses a deadline?
The operating agreement says "members can't transfer without consent." The buy-sell agreement says "here's exactly how the transfer works, how much it costs, and where the money comes from."
One is a restriction. The other is a plan.
How They Work Together
These documents shouldn't exist in isolation. When properly structured:
- The operating agreement references the buy-sell agreement and defers to it on all matters related to ownership transitions.
- The buy-sell agreement overrides the operating agreement on anything related to transfer of interests, valuation, and buyout mechanics.
- Both documents are drafted together—or at minimum, reviewed together by the same attorney—to ensure they don't contradict each other.
When the two documents conflict, it creates ambiguity. Ambiguity leads to disputes. Disputes lead to litigation. The simplest way to prevent this: have your attorney draft or review both at the same time, and include explicit language about which document takes priority on ownership-related matters.
When the Gap Hurts
Two partners own a consulting firm as a 50/50 LLC. They have a solid operating agreement that covers management responsibilities, profit splits, and a clause requiring mutual consent for any transfer of membership interests. They never got around to a buy-sell agreement.
One partner dies unexpectedly. The surviving partner now faces the deceased partner's estate—specifically, a spouse who knows nothing about the business but now controls 50% of it.
There is no agreed-upon valuation method. The surviving partner thinks the business is worth $1.2 million. The estate's attorney argues it's worth $2.4 million. There is no funding in place—no insurance, no reserve, no installment terms. There is no timeline for resolution.
The operating agreement says the surviving partner has the right to buy the interest, but it says nothing about the price, the funding, or the process. Eighteen months and $180,000 in legal fees later, they settle at a number neither side is happy with—and the business lost two major clients during the dispute.
A funded buy-sell agreement would have resolved this in weeks, not years. The valuation would have been predetermined. The insurance would have provided immediate cash to complete the buyout. The estate would have been paid fairly and promptly. The business would have continued without disruption.
Close the Gap Now
If your business has two or more owners, an operating agreement alone is not enough. It was never designed to handle the financial and logistical reality of an ownership transition. A buy-sell agreement fills that gap—and insurance funding makes sure the agreement actually works when it's triggered.
