LLC Operating Agreement & Banking Resolution Generator

LLC Operating Agreements and Banking Resolutions: Generate Them Right

Every year we talk to founders who formed an LLC in an afternoon, got their EIN in a day, and then hit a wall three weeks later when a bank teller asks for "the operating agreement" and a "resolution authorizing this account." Cue the blank stare. If that's you — or you'd like to avoid ever being that person — this is the article for you.

We're going to walk through what these two documents actually do, which states legally require them, the clauses that matter most, how banks and fintechs like Mercury, Relay, and Wise use them, and where AI-assisted drafting genuinely helps versus where it can get you into trouble. One quick note before we start: this article is educational, not legal advice. LLC law varies by state and your situation may need a licensed attorney — more on when that matters below.

What an Operating Agreement Actually Is

An operating agreement is the internal rulebook for your LLC. It's a private contract among the members (owners) that spells out who owns what percentage, who makes decisions, how profits get split, and what happens if someone wants out, dies, gets divorced, or the business needs to close.

Think of the Articles of Organization (the document you file with the state) as your LLC's birth certificate — it proves you exist. The operating agreement is more like the prenup, the employee handbook, and the succession plan rolled into one. States generally don't require you to file it anywhere; it lives in your company records, not with the Secretary of State.

Why Single-Member LLCs Still Need One

We hear this constantly: "It's just me, why do I need an agreement with myself?" Three reasons, and none of them are theoretical.

Liability protection. Courts occasionally "pierce the corporate veil" — treating an LLC as if it doesn't exist and exposing the owner's personal assets — when the owner hasn't treated the LLC as a separate entity. A signed operating agreement is one of the clearest pieces of evidence that you did.
Banking and fintech requirements. Nearly every bank and business fintech account application asks for one, single-member or not. No document, no account, full stop.
Future-proofing. Plans change. You bring on a co-founder, take on an investor, or want to transfer interest to a trust or spouse. Having a document already in place — even a simple one — makes that transition far cleaner than drafting one under time pressure during a deal.

We've seen single-member LLC owners lose personal-liability protection in litigation specifically because they had no operating agreement and commingled funds. It's a cheap insurance policy that costs you an hour, not a lawyer's retainer.

Which States Actually Require One

Most states don't mandate that you have a written operating agreement, but five states do require LLCs to adopt one (the requirement is rarely enforced by a filing, but it's on the books):

State	Written Requirement?	Notes
California	Yes	Cal. Corp. Code §17701.11 — required, oral or written, but written strongly advised
New York	Yes	Must be adopted within 90 days of filing Articles of Organization
Missouri	Yes	Required for all LLCs, can be oral or written
Maine	Yes	Required under Title 31
Delaware	Practically yes	Not "required" by statute in the same way, but Delaware's LLC Act is built around the operating agreement governing almost everything — banks and courts expect one

Everywhere else — Texas, Florida, Wyoming, and the rest — it's optional by law but effectively mandatory in practice, because banks, investors, and courts all expect to see one. We tell clients: legally optional and practically optional are two very different things.

The Clauses That Matter

A good operating agreement isn't a form you fill in with your company name and call done. Here are the clauses that actually get scrutinized — by banks, by courts, and by that co-founder who leaves in year two.

Clause-by-Clause Breakdown

Clause	What It Covers	Why It Matters
Membership Interests	Each member's ownership percentage and class of interest	Determines who gets what in a sale, and voting weight if tied to ownership
Capital Contributions	Cash, property, or services each member put in, and future contribution obligations	Prevents disputes over "I put in more than you" and clarifies tax basis
Distributions	How and when profits/losses are allocated and paid out	Avoids arguments when the business is profitable but cash is tight
Management Structure	Member-managed vs. manager-managed	Tells banks and vendors who actually has authority to sign contracts
Voting Rights	What requires unanimous consent vs. majority vs. supermajority	Prevents deadlock and clarifies who can authorize big decisions
Transfer Restrictions	Rules on selling or transferring membership interest (rights of first refusal, etc.)	Stops a member from selling their stake to a stranger without consent
Dissolution	Triggers and process for winding down the LLC	Sets a clear exit path instead of a messy court-supervised one
Indemnification	Protects members/managers from personal liability for good-faith business decisions	Reduces exposure for managers making tough calls on the company's behalf
Buy-Sell / Death or Incapacity	What happens to a member's interest if they die, divorce, or become incapacitated	Keeps ex-spouses or unrelated heirs from suddenly becoming your business partner
Amendment Process	How the agreement itself can be changed	Prevents one member from unilaterally rewriting the rules later

Skipping any of these doesn't void your LLC, but it does leave a gap that state default law fills in — and default law is rarely written with your specific business in mind. Delaware's default rules, for instance, assume equal management rights regardless of ownership percentage, which surprises a lot of 90/10 founder splits.

Multi-Member vs. Single-Member: What Actually Changes

The core structure of an operating agreement is similar either way, but the emphasis shifts.

Single-member LLCs mostly need the document for:

Proving separateness from the owner personally (the veil-piercing issue above)
Satisfying banks, which don't care that you're the only member — they still want the document
Setting a plan for what happens if you become incapacitated or die (your LLC doesn't just dissolve automatically, but without a plan your heirs face more friction)

Multi-member LLCs need real negotiation on:

Voting thresholds and deadlock-breaking mechanisms
Capital call obligations if the business needs more cash later
Buy-sell provisions and valuation methods when a member exits
Non-compete or non-solicit clauses between members
Tax allocation methods, especially if contributions are unequal

If you're a two-person 50/50 LLC with no tie-breaker clause, you have essentially built a company that can freeze the moment you disagree on anything material. We've seen that exact scenario stall a company for eight months over disagreement on a $4,000 software purchase. A well-drafted voting and deadlock clause avoids that entirely.

What a Banking Resolution Is (and Why the Bank Wants One)

A banking resolution — sometimes called an LLC resolution to open a bank account, or corporate resolution — is a short document where the LLC formally authorizes specific individuals to open, manage, and transact on a business bank account on the company's behalf. It typically states:

The LLC's legal name, formation state, and EIN
The name(s) and title(s) of the authorized signer(s)
What those signers are permitted to do (open accounts, sign checks, apply for credit, wire funds, etc.)
A certification that the resolution was adopted according to the operating agreement
Signatures of the members/managers approving it, with a date

When Banks and Fintechs Ask for It

Provider	Typically Requires Resolution?	Notes
Traditional banks (Chase, Bank of America, etc.)	Almost always	Especially for multi-member LLCs or when the account signer isn't the registered agent
Mercury	Sometimes	Usually requested for multi-member LLCs or when ownership is unclear from formation documents
Relay	Often for multi-member LLCs	Single-member accounts sometimes skip it if the operating agreement clearly names the sole authorized signer
Wise Business	Case by case	More document-heavy for non-US resident founders; a resolution helps establish signer authority quickly

In our experience, the pattern is simple: the more ambiguous your management structure looks on paper, the more documentation a compliance team will ask for. A one-member LLC where you're clearly the sole member and manager sometimes squeaks by with just the operating agreement. A three-member LLC with a manager who isn't a member at all will almost always need a resolution naming that person explicitly.

Common Mistakes That Get Accounts Rejected

We've reviewed enough rejected bank applications to see the same handful of errors repeatedly:

Name mismatches. The LLC name on the operating agreement doesn't exactly match the Articles of Organization (missing "LLC," different punctuation, etc.). Banks' compliance software flags this instantly.
Unsigned or undated documents. An operating agreement without signatures is, legally, a draft. Banks treat it as such.
EIN not yet issued or mismatched. Applying for a bank account before your EIN confirmation letter (CP 575) arrives, or using an EIN tied to a different entity name.
Vague authority language. A resolution that says "member has authority to manage the company" without specifying banking powers explicitly (open accounts, sign checks, initiate wires) often gets kicked back for clarification.
Outdated ownership information. You added a member last year but never amended the operating agreement or issued a new resolution — the bank's records now conflict with your actual structure.
Missing beneficial ownership information. Since the Corporate Transparency Act's beneficial ownership reporting requirements took effect, banks increasingly cross-check who you say owns 25%+ of the company against what you've filed or disclosed elsewhere.

EIN and Beneficial Ownership Context

Two pieces of context worth having in the back of your mind while you're drafting these documents:

EIN (Employer Identification Number): Your EIN is issued by the IRS and tied to the exact legal name and structure you reported on Form SS-4. If your operating agreement lists members or a management structure that doesn't match what you told the IRS, expect friction — not because it's illegal, but because banks reconcile these documents against each other and flag mismatches for manual review.

Beneficial Ownership Information (BOI): Under the Corporate Transparency Act, many LLCs must report beneficial owners — generally anyone with 25%+ ownership or substantial control — to FinCEN. Your operating agreement's membership interest and management clauses are usually the source document for figuring out who counts as a beneficial owner. Keep them consistent; discrepancies between your BOI report and your operating agreement are exactly the kind of thing that turns a routine compliance review into a drawn-out one. (Reporting obligations under the CTA have shifted in scope over time, so check current requirements for your entity before relying on any specific rule.)

Using an AI Generator Safely

AI-generated operating agreements and resolutions have gotten genuinely good at handling the standard 80% of clauses — member percentages, basic distributions, standard indemnification language, boilerplate dissolution triggers. That's most of what a straightforward single-member or simple two-member LLC needs.

Where we'd slow down and get human eyes on it:

Unequal capital contributions combined with equal voting rights (or vice versa) — this is where ambiguity causes the most disputes later
Multi-member LLCs with outside investors or convertible notes, where the operating agreement needs to interact with other financing documents
Any LLC planning to raise capital, bring on a manager who isn't a member, or eventually convert to a corporation — these all have downstream legal consequences an AI tool won't flag
Cross-border ownership, where tax treaty issues or foreign beneficial ownership reporting adds complexity a template can't anticipate

A practical rule we use ourselves: if you can explain your entire ownership and management structure in two sentences, an AI-generated agreement plus a quick self-review is usually fine. If it takes a paragraph with multiple "but if X happens" clauses, get an attorney to look at it before you sign.

Where Bizvee Fits In

That's the honest way to use AI drafting tools: fast and free for the standard cases, escalate to a licensed professional when the stakes or complexity go up. We'd rather tell you to get a 30-minute attorney review than have you find out the hard way that your buy-sell clause has a hole in it.

FAQ

Do I need a lawyer to write an LLC operating agreement? Not usually, for a straightforward single-member or simple multi-member LLC. A well-built template or AI generator covers the standard clauses correctly. Get an attorney involved if you have unequal contributions with complex voting arrangements, outside investors, or plans to raise capital.

Can I open a business bank account without an operating agreement? Sometimes, especially for single-member LLCs at fintechs like Mercury or Relay, but most traditional banks will ask for one regardless of how many members you have. It's easier to have it ready than to scramble when asked.

What's the difference between an operating agreement and a banking resolution? The operating agreement governs the LLC's internal structure and ownership long-term. The banking resolution is a narrower, specific document that authorizes named individuals to act on a particular bank account — you may need a new resolution each time you open an account or change signers, even though your operating agreement stays the same.

Does my operating agreement need to be filed with the state? No. Unlike your Articles of Organization, the operating agreement is an internal document. You keep it in your company records — banks and courts may ask to see it, but you don't file it publicly (with rare exceptions in specific state processes).

What happens if I never update my operating agreement after adding a new member? Legally, your LLC's actual ownership may not match what's written down, which creates real problems — for tax allocations, for BOI reporting accuracy, and for bank compliance reviews. Amend it every time ownership or management changes, even if it feels like paperwork for paperwork's sake.
