An operating agreement is the internal contract between a South Dakota LLC's members. Every formation we file includes a custom one, drafted to your actual ownership — not a template.
An operating agreement is the governing document for your South Dakota LLC. It's a contract among the members — or, in a single-member LLC, a statement by the sole owner — that sets out how the LLC is owned, how it's managed, how profits are split, and how the LLC is wound down if the members part ways.
Unlike the Articles of Organization (which are filed with the South Dakota Secretary of State and become public record), an operating agreement is an internal document. It is not filed with the state. It sits with you and your co-owners, and gets pulled out when you open a bank account, take on a partner, or resolve a dispute.
South Dakota does not require every LLC to have a written operating agreement. But South Dakota has default rules that kick in when there isn't one — rules about how profits are split, how votes are counted, and what happens when a member dies or wants out. Those defaults are often the opposite of what founders assume.
Put another way: your South Dakota LLC has an operating agreement the moment it's formed. Either you wrote it, or South Dakota wrote it for you via the state's default statute. Most founders want the first option.

Member names, ownership percentages, initial capital contributions, and how additional capital is handled. Reflects your actual numbers — not placeholders.
Member-managed (members run the business) or manager-managed (appointed managers run the business). South Dakota allows both; we draft to match what you've chosen.
How decisions are made — majority vote by percentage, unanimous consent for major decisions, tie-breaking mechanics.
How profits and losses are allocated, and how cash distributions to members are timed and sized.
What happens when a member wants to sell their interest, leave the LLC, or dies. Right of first refusal, valuation mechanics, buyout terms.
What triggers dissolution of the South Dakota LLC, how remaining assets are distributed, and how the LLC is formally wound down.
Every major U.S. bank will ask for the operating agreement when you open a business account for your South Dakota LLC. They use it to confirm who has signing authority, who can authorize wires, and who is legally able to open the account on the LLC's behalf. A generic template without real member details — or worse, no agreement at all — can hold up account opening for days.
Our operating agreements are drafted, reviewed, and delivered signature-ready in PDF and Word. They've been accepted at every major U.S. bank and most credit unions we've seen — Chase, Bank of America, Wells Fargo, U.S. Bank, Capital One, Mercury, Novo, Relay, Bluevine, and the dozens of regionals in between.
Even if you're the sole owner of a South Dakota LLC, you want an operating agreement. It's the document that proves your LLC is a legitimate separate entity — which matters for the liability shield (corporate-veil protection) and for bank account opening. A one-page document is not sufficient; banks and courts look for actual substance.
For multi-member LLCs, the operating agreement is the most important document you'll produce in year one. Handshake agreements between co-founders turn into litigation when one wants to leave. We draft to the terms you've agreed, which is usually the easiest time to be specific about edge cases.
