Operating Agreement Basics: Why You Need One

Most states don't require LLCs to have an operating agreement, which means most LLCs don't have one. That's a mistake. Here is what operating agreements do and why even single-member LLCs need one.
Educational note: This guide explains general operating agreement concepts. Specific provisions for your business should be drafted with a business attorney, especially for multi-member LLCs.

What an operating agreement is

An operating agreement is the internal governance document for your LLC. It's an agreement between the members (owners) about how the LLC will be run, how decisions get made, how profits and losses are allocated, and what happens when changes occur.

Unlike Articles of Organization (which are filed with the state and become public), the operating agreement is internal — it's not filed anywhere, but it governs how the business actually operates. It's the rulebook the members agree to follow.

Why states don't require it (and why that's misleading)

Most states don't require LLCs to have an operating agreement. The state's default LLC laws apply if you don't have your own agreement. This sounds convenient — why create a document if the state already has rules?

The problem: the state's default rules are generic and often don't match what you actually want. They allocate profits equally among members regardless of capital contributions. They require unanimous consent for many decisions. They have specific (often unhelpful) provisions for member departures, disputes, and dissolution.

Operating without an agreement means agreeing to the state's defaults by silence. Most members would prefer different arrangements but never realize they're bound to defaults until a problem arises.

What an operating agreement covers

Ownership and capital contributions

Profit and loss allocation

Management structure

Member rights and obligations

Transfer of ownership

Member departure, death, or incapacity

Dispute resolution

Dissolution

Why single-member LLCs need one too

Single-member LLCs especially benefit from operating agreements despite having no one to "agree" with. Reasons:

1. Reinforces the corporate veil

Single-member LLCs face the highest risk of "veil-piercing" — courts treating the LLC as the owner's alter ego and allowing personal liability for business debts. An operating agreement that documents the LLC's separate existence, decision-making procedures, and operational formalities strengthens the veil.

2. Bank and lender requirements

Many banks require operating agreements before opening business accounts. Lenders increasingly require them as part of loan documentation. Investors require them if you take outside investment.

3. Establishes your authority

If you need to act on behalf of the LLC (sign contracts, hire employees, take loans), the operating agreement documents your authority. Without it, your authority comes from state default rules which are less specific.

4. Future-proofing

Your single-member LLC might become multi-member someday (taking a partner, bringing in family, accepting investment). Having an operating agreement from the start, even if it's simple, establishes the foundation for adding members later.

The cost spectrum: DIY to attorney-drafted

DIY templates ($0)

Many reputable sources publish free operating agreement templates: Nolo, your state bar association, SBA resources, established small business publications. For simple single-member LLCs, these are usually adequate.

Risks: templates can be too generic for your situation, miss state-specific provisions, or include problematic language. Read carefully before adopting.

Online services ($75-$200)

LegalZoom, Rocket Lawyer, IncFile, and similar services offer customized operating agreements based on a questionnaire. Better than blank templates because they incorporate basic information about your business. Still relatively generic.

Attorney-drafted ($500-$2,500)

A business attorney drafts an operating agreement specifically for your situation. The attorney considers your state's specific laws, your industry's common provisions, your ownership structure, and your specific concerns. Most expensive option but highest value for multi-member LLCs.

When to spend on attorney drafting

Always for multi-member LLCs

The $500-$2,500 attorney cost is small relative to the cost of resolving disputes when members can't agree. A well-drafted operating agreement prevents 80%+ of the disputes that hit small business courts.

For single-member LLCs with valuable IP or assets

If your LLC holds significant intellectual property, real estate, or other valuable assets, attorney-drafted agreements provide better protection.

For LLCs in regulated industries

Medical practices, law firms, accounting firms, financial services — industries with specific regulatory requirements need attorney input to ensure compliance.

For LLCs with complex tax structures

If your LLC will use complex tax structures (special allocations, guaranteed payments, etc.), attorney input ensures the operating agreement supports the tax treatment.

Common operating agreement mistakes

1. No buyout valuation methodology

"Member X buys out Member Y" sounds simple until you have to decide what price. Operating agreements should specify valuation methodology (book value, multiple of earnings, appraisal, etc.) so departure scenarios don't become litigation.

2. Vague decision-making

"Members will decide major matters by majority vote" leaves "major matters" undefined. Be specific: which decisions require what level of agreement.

3. No provisions for member departure

What happens if a member wants to leave? Just leaving doesn't terminate their ownership; they're still entitled to their share of profits. Without buyout procedures, you end up with absent owners who still have rights.

4. No spouse provisions

Marriages end. What happens if a member divorces? In community property states, the spouse may have claims on the LLC interest. Operating agreements should address this.

5. Outdated information

Operating agreements need to be updated when circumstances change (new members, departure of members, change in ownership percentages, etc.). Many LLCs draft an agreement at formation and never update it.
