How to Start a Fractional CFO Practice: The First 90 Days

You have spent 15, 20, maybe 25 years inside organizations, running finance functions, managing teams, and driving outcomes that moved the needle. Now you are ready to go independent. Maybe you are tired of corporate politics. Maybe you want more control over your time. Maybe you see the fractional CFO market growing and want to build something of your own. Whatever the reason, you are facing a challenge that your finance career did not prepare you for: building a business from scratch. The good news is that launching a fractional CFO practice does not require a massive investment, a complex business plan, or years of runway. It requires clarity, discipline, and a systematic approach to the first 90 days. This guide gives you the complete playbook.

Before you hand in your notice or start telling people you are available, you need to answer three questions honestly.

First, do you have enough financial runway? The standard advice is six months of living expenses, but for a fractional CFO practice, I recommend 9 to 12 months. It typically takes 60 to 90 days to land your first client, and another 30 to 60 days before you receive your first payment. If you are launching from a position of financial stress, that pressure will show up in your pricing, your positioning, and your conversations with prospects.

Second, do you have a clear picture of who you want to serve? This is not about having a perfect niche on day one. It is about having a hypothesis. What industry do you know best? What company stage have you spent the most time in? What financial problems have you solved repeatedly and well? You will refine this over time, but you need a starting point.

Third, are you prepared to do the work of business development? This is the part that surprises most new fractional CFOs. You are not just a finance professional anymore. You are a business owner, and that means you need to spend 30 to 50 percent of your time in the first 90 days on marketing, networking, and outreach. If the idea of selling yourself feels uncomfortable, that is normal. But it is not optional.

The first ten days are about building the infrastructure of your practice. This is not glamorous work, but it is necessary.

Legal and financial setup. Form your entity. Most fractional CFOs operate as a single-member LLC, which provides liability protection and tax flexibility. Open a business bank account. Get professional liability insurance, also known as errors and omissions insurance. Set up a simple bookkeeping system. You are a CFO. Your own books should be impeccable.

Define your positioning. Based on your pre-launch thinking, write a clear positioning statement: who you serve, what problem you solve, and what outcome you deliver. This does not need to be perfect. It needs to be specific enough to guide your next steps. Our fractional CFO positioning guide walks through this in detail.

Set your pricing. Based on the market data and frameworks in our pricing guide, set your initial retainer rates. Start at the second tier ($5,000 to $8,000 per month) unless you have a strong reason to go higher or lower. You can always adjust as you learn more about your market.

Build your target list. Identify 50 companies that match your ideal client profile. Find the decision-makers at those companies on LinkedIn. This list will drive your outreach efforts for the next 80 days.

With the foundation in place, the next 20 days are about making yourself visible to your target market.

Rebuild your LinkedIn profile. This is the single most important marketing asset you will build. Your headline should name your niche and your outcome. Your About section should speak directly to your ideal client. Your Featured section should showcase relevant content or a link to your free audit. Our LinkedIn strategy guide covers the full profile optimization framework.

Start creating content. Begin posting on LinkedIn two to three times per week. Your first posts should focus on the problems your ideal clients face, written in their language, with enough specificity that they feel seen. Do not worry about going viral. Worry about being relevant to the 50 people on your target list.

Activate your network. Send a personal message to every relevant contact in your network. Not a mass announcement. A personal, one-to-one message that explains what you are doing, who you are looking to help, and asks if they know anyone who might benefit. Be specific about the type of referral you are looking for. "Do you know any SaaS founders between $3M and $10M who are struggling with cash flow visibility?" is infinitely more useful than "Let me know if you hear of anyone who needs a CFO."

Build a simple web presence. You do not need a complex website on day one. A clean, one-page site that reinforces your positioning, showcases your credentials, and provides a clear call to action is sufficient. The goal is to give prospects a place to learn more about you after they see your LinkedIn profile or receive your outreach message.

By day 31, your positioning is defined, your LinkedIn profile is optimized, and you are posting content consistently. Now it is time to build pipeline through proactive outreach.

Launch your outreach system. Using your target list of 50 companies, begin the engagement sequence. Engage with their content on LinkedIn. Send personalized connection requests. Share relevant content. Build relationships before you pitch. This is a 30 to 90 day process per prospect, which is why you need to start now.

Aim for conversations, not closes. Your goal in this phase is to generate four to eight discovery conversations per month. Not all of them will convert to clients. That is fine. Each conversation teaches you something about your market, your positioning, and your sales process. The fractional CFOs who succeed are the ones who treat every conversation as a learning opportunity.

Develop your diagnostic tool. Create a structured assessment or audit that you can offer to prospects as a free entry point. This could be a financial health scorecard, a cash flow diagnostic, or a readiness assessment for fundraising or exit. The diagnostic serves two purposes: it gives the prospect immediate value, and it gives you a structured way to demonstrate your expertise and identify specific opportunities for engagement.

Refine your positioning based on feedback. Pay attention to how prospects respond to your messaging. Which problems resonate most? Which outcomes generate the most interest? Which objections come up repeatedly? Use this feedback to sharpen your positioning and your content. The positioning you started with on day one should be noticeably more refined by day 60.

Track your metrics. Keep a simple spreadsheet tracking: outreach messages sent, connections accepted, conversations started, discovery calls booked, and proposals sent. This gives you a clear picture of your funnel and helps you identify where the bottleneck is. If you are not sure what to track, our guide on getting clients as a fractional CFO covers the full metrics framework.

By day 61, you should have several active conversations and at least one or two prospects who are seriously considering an engagement. This phase is about converting those conversations into retainer clients and optimizing your system for the long term.

Master the discovery call. The discovery call is where deals are won or lost. Structure it in three parts: diagnose (understand their specific challenges and the impact on their business), prescribe (explain your approach and the outcomes they can expect), and propose (present the investment and the next steps). Do not rush to the proposal. Spend at least 60 percent of the call on diagnosis.

Send proposals that sell. Your proposal should not be a list of services and a price. It should be a document that restates the client's specific challenges, outlines the outcomes you will deliver, describes your approach, and presents the investment in the context of the value created. A good proposal makes the decision feel obvious.

Close your first client. Your first client is the hardest to land and the most important. They validate your positioning, give you a case study, and provide the confidence boost you need to keep going. Do not discount your fees to close them. If your positioning and discovery process are strong, the right clients will pay your full rate.

Optimize your system. Review your 90-day metrics. What is your connection acceptance rate? How many conversations are you generating per month? What is your conversion rate from discovery call to proposal? From proposal to signed engagement? Identify the weakest link in your funnel and focus your energy there.

Plan for month four and beyond. The first 90 days are about building the foundation. Months four through twelve are about scaling. Continue posting content. Expand your target list. Refine your outreach messaging. Build your referral network. The system you built in the first 90 days should be generating a predictable flow of conversations by now. Your job is to keep feeding it.

Having worked with dozens of fractional CFOs in their first year of practice, I have seen the same mistakes repeated. Avoiding them will save you months of frustration and thousands of dollars in lost revenue.

Waiting for referrals instead of building a system. Referrals are wonderful, but they are not a strategy. The fractional CFOs who build sustainable practices are the ones who treat client acquisition as a system from day one, not something they will figure out later.

Underpricing to win early clients. Your first clients set the anchor for your pricing going forward. If you start at $3,000 per month because you are nervous about charging more, you will spend the next year trying to raise your rates. Start at a rate that reflects your value, even if it means waiting a few extra weeks for the right client.

Trying to do everything yourself. You are a CFO, not a bookkeeper, a graphic designer, and a social media manager. Outsource the things that are not in your zone of genius. Hire a bookkeeper for your own practice. Use a virtual assistant for scheduling and administrative tasks. Invest in tools that save you time.

Not investing in positioning. The fractional CFOs who struggle the most in their first year are the ones who skip the positioning work and jump straight to outreach. Without clear positioning, your outreach is generic, your content is unfocused, and your discovery calls lack conviction. Positioning is the foundation. Build it first. For a detailed look at the most common mistakes, read our guide on 7 fractional CFO marketing mistakes that kill your pipeline.

At the end of 90 days, a well-executed launch should have produced the following results. Your LinkedIn profile is fully optimized for your niche and is generating profile views from your target audience. You have published 20 to 30 pieces of content that demonstrate your expertise. You have sent 100 to 150 personalized outreach messages and started 15 to 25 conversations with potential clients or referral partners. You have conducted 5 to 10 discovery calls. And you have signed one to three retainer clients at your target rate.

If your numbers are below these benchmarks, do not panic. The system is working. It just needs more time and refinement. Review your metrics, identify the bottleneck, and adjust. If your connection acceptance rate is low, your outreach messaging needs work. If you are getting conversations but not converting, your discovery call process needs refinement. If you are not getting any traction at all, your positioning may need to be sharper.

The most important thing at 90 days is that you have a system in place. Not a hope. Not a plan to start marketing next month. A functioning system that is generating conversations with potential clients on a predictable basis. Everything else, the revenue, the client roster, the reputation, builds from there.
