How to Start a Fractional Practice: LLC, Contracts, Insurance & First Client
Starting a fractional practice is less about a grand launch and more about a short setup checklist: an entity, a contract, insurance, a way to invoice, and a first client. Get those five things in place and you are in business — the rest is iteration.
Decide if you actually need to "start" anything yet
You can take your first fractional client as a sole proprietor under your own name and Social Security number, invoice them, and pay tax on the income. Nothing illegal about it. But the moment you are advising companies on real decisions and money is changing hands, you want a cleaner separation between you and the work — for liability, for taxes, and for how you look to a buyer comparing you to other operators.
The honest answer for most people: set up the entity early, but do not let it become a procrastination project. You do not need a logo, a brand, or a website to land client one. You need to be able to sign a contract and send an invoice. Everything below can be done in a week or two, often in parallel.
Choose your entity: LLC, S-corp, or sole prop
For a solo fractional operator in the US, the practical choice is almost always a single-member LLC. It is cheap to form, gives you a liability shield between your personal assets and the business, and lets you open a business bank account and sign contracts under the company name. By default it is taxed as a pass-through, so you are not adding a separate corporate tax return on day one.
The S-corp question comes later. An LLC can elect to be taxed as an S-corp, which can save on self-employment tax once your net profit is high enough to justify running payroll for yourself and the added accounting cost. That is a conversation for your accountant once you have real revenue — not a reason to delay forming the LLC now.
| Structure | Liability shield | Setup effort | Best when |
|---|---|---|---|
| Sole proprietor | None | Zero | Testing one engagement before committing |
| Single-member LLC | Yes | Low | Almost every fractional practice, at the start |
| LLC with S-corp election | Yes | Medium | Once net profit is high enough to justify payroll |
Whatever you pick, do the boring follow-through: get an EIN from the IRS (free, takes minutes online), open a dedicated business checking account, and never run client money through your personal account. That single habit keeps your bookkeeping clean and your liability shield intact.
Get your contracts right: MSA plus SOW
You do not need a custom contract for every client. The standard structure for ongoing fractional work is two documents that work together:
- Master Services Agreement (MSA). The legal terms that rarely change: payment terms, confidentiality, intellectual property ownership, limitation of liability, indemnification, who owns the work product, and how either side can end the relationship. You sign this once per client.
- Statement of Work (SOW). The specific engagement: what you will do, the time commitment, the rate and billing cadence, the term, and what is explicitly out of scope. You write a fresh SOW for each engagement or when the scope changes.
Splitting them this way means renewing or expanding an engagement is a one-page SOW, not a renegotiation of the whole contract. A few terms are worth getting right from the start: clarify that you are an independent contractor, not an employee; cap your liability at the fees paid; and define a clean termination clause — most fractional agreements use 30 days' written notice either way. Have a lawyer review your template once. After that, reuse it.
Carry the right insurance
The insurance that matters for advisory work is professional liability, also called errors and omissions (E&O). It covers claims that your advice or work caused a client financial harm. Plenty of fractional operators skip it until a client asks — and mid-size or enterprise clients increasingly require proof of coverage before they will sign. It is easier to have it in hand than to scramble during onboarding.
A general liability policy is cheap and often bundled; it covers ordinary business stuff like bodily injury and property damage, which matters less for desk work but is sometimes also a contract requirement. As a rough sense of the market, most solo professionals pay somewhere between a few hundred and a couple thousand dollars a year for E&O, depending on coverage limits, your field, and how much risk the work carries. Get a quote before you assume it is expensive — for many advisory practices it is one of the smaller line items.
Set up invoicing and get paid
Your invoicing system can be simple, but it has to be consistent. At minimum you need a way to send a clean, professional invoice and a way to receive payment without losing a cut to friction. A few principles that save you headaches:
- Bill on a predictable cadence. Most fractional retainers bill monthly, in advance. Project work often bills on milestones. Decide before the engagement starts and put it in the SOW.
- State your payment terms in writing. Net 15 or net 30, plus what happens if payment is late. Vague terms are how you end up chasing money.
- Keep a paper trail. Number your invoices, save them, and reconcile against your business account. Your future self at tax time will thank you.
- Set money aside for taxes. No employer is withholding for you now. A common rule of thumb is to park 25 to 35 percent of profit for federal and state taxes and pay quarterly estimates.
Land your first client
All the setup in the world does not matter until someone pays you. Your first client almost never comes from a cold market — it comes from people who already know your work. Make a list of former colleagues, founders you have helped, and people in your network who know what you are good at, and tell them plainly that you are taking on fractional and advisory engagements. Be specific about the problem you solve and the kind of company you serve. Specific is memorable; "I'm available for consulting" is not.
Then make yourself findable. The buyers searching for a fractional CFO or a fractional head of product are often comparing a handful of people on what they do, what stage they serve, and what they charge. If your background and your terms are clear and easy to find, you shorten the gap between "we need someone like this" and "let's book them." First clients beget referrals, and referrals are how a fractional practice actually compounds.
That last step — being findable on your own terms — is what ExecRoster is for. You publish one profile that states your background, the work you take, your industries, and your rate, then get found and booked directly by the companies that need exactly that. You set the terms, keep about 90% of what you book, and there is no recruiter in the middle.
