The short answer
Fractional CFOs and specialist finance firms win more clients by getting known by the right few business owners and finance leaders before they need help. Use LinkedIn to put the partner in front of companies of the right size and sector, Google to catch people already searching for the service, and Meta to retarget visitors. Lead with a useful diagnostic or guide rather than a cold "book a call", and track every lead in your CRM through to proposal and signed retainer.
- Accept that your market is small. You need the right few business owners and finance leads to know you, not lots of people to click.
- Use LinkedIn to make the partner known, aimed at companies by size and sector and at the job titles who hire you.
- Use Google for people already searching for the service, and Meta to retarget everyone who visited.
- Offer something useful before asking for a call, such as a short diagnostic or a checklist.
- Track every lead to a signed retainer in your CRM, and judge it over quarters, not weeks.
For one finance consultancy: 24 qualified sales calls in 8 weeks and a 12X ROI. For an accountancy firm launching a fractional CFO service: 80+ leads in the first 6 weeks and a 7.5X ROI. See both.
Most fractional CFO and specialist finance firms I speak to have the same story. The partners are good at the work. Clients stay for years. Almost every one of them came through a referral, an old colleague or the partner's own network.
That's a great way to win work and a terrible way to plan growth. Referrals arrive when they arrive. The partner's network was built over twenty years and doesn't get bigger on demand. And when a prospect does look you up, your website says roughly what every other accountant's website says.
Ads can fix this, but not the way most finance firms try them. One campaign to "business owners", a message about trusted advice and a button to book a free consultation. It rarely works, and the reason is the market, not the ads.
01You sell to a small market of high-value, high-trust buyers
Fractional CFOs, outsourced FDs, finance consultancies, accountancy firms adding advisory work, tax specialists, commercial finance and valuation advisers all sell into the same kind of market:
The buyers are few
Your market isn't every business in the UK. It's the owners and finance leads at companies of a certain size, in sectors you understand, at a moment when they need you. That's a short list.
Each one is worth a lot
A fractional CFO or advisory client usually stays on a monthly retainer. One good client can be worth more than a year of ad spend.
Trust comes before the call
Nobody hands their numbers to a stranger off the back of one ad. They want to have seen your thinking, more than once, before they'll talk to you.
You look like everyone else
"Trusted advisers for growing businesses" could be any accountant in the country. If the buyer can't tell you apart, they go with whoever they already know.
Put those together and the job of your ads changes. You're not trying to generate as many leads as possible. You're trying to make sure the right few business owners and finance leads have seen you, understood what you do and trusted you enough to take a first step. A thousand clicks from the wrong people is worth less than ten visits from the right ones.
Go deeper: why small markets need a different approach to ads is covered in our guide to marketing in a small B2B market.
02LinkedIn, Google and Meta each have one job
Each channel does something different. Run them as one blended "digital marketing" budget and you can't tell which one is working.
- Who it reaches
- Founders, MDs, FDs and CFOs at companies of the right size and sector
- Judge it on
- Diagnostic completions, booked calls and proposals
- Who it reaches
- Anyone searching for the exact service you offer
- Judge it on
- Enquiries and booked calls per search theme
- Who it reaches
- People who visited your site or engaged with your content
- Judge it on
- Return visits that turn into a diagnostic or a call
LinkedIn: founder-led authority, aimed at the right companies
Finance is bought from people, not logos. The most useful thing LinkedIn can do for you is put the partner's face and thinking in front of the same few hundred business owners and finance leads, week after week, until they feel they know you. Promoting the partner's own posts as Thought Leader Ads does that better than any company page ad. See our guide to Thought Leader Ads.
Keep the targeting simple and tight:
- Pick the companies. Upload a list of the businesses you want, or use company size and industry if you don't have one yet. Match it to the clients you already serve well.
- Pick the job titles of the people who hire you: founder, owner, MD, CEO, finance director, CFO, head of finance.
- Set the location to where you actually take on clients.
- Don't stack seniority, job function or skills on top. The "Finance" job function alone includes everyone from a junior ledger clerk to a group CFO. Titles at the right companies are cleaner.
- Turn LinkedIn Audience Expansion off, so your budget stays on the people you chose.
Our guide to LinkedIn company list uploads covers the mechanics, and the LinkedIn Ads guide for professional services goes deeper on message and creative.
Google: catch the people already searching
Some business owners do search for exactly what you offer. Those searches look something like this:
- fractional CFO for startups
- outsourced finance director
- R&D tax specialist for SMEs
- business valuation before selling
- commercial finance adviser
Example searches written for this guide.
When someone types one of those, they have a need right now. Send them to a page about that exact service, with who it's for, what it costs to work with you or how pricing works, proof from similar clients and a clear next step. Not the homepage.
Two warnings. First, for niche finance services the number of searches is small, so Google catches the demand that exists but can't create more. Most of the owners who need a fractional CFO have never searched for one. Second, finance terms attract a lot of the wrong searches: job hunters, trainees, people looking for HMRC phone numbers and help with their own tax return. Block them from day one with our free negative keyword list for professional services firms, and check the search terms report every week.
Meta: retarget everyone who visited
Most of the right people will visit your site, read a page and leave. That's normal for a decision this big. Meta retargeting puts your case studies, the partner's story and your diagnostic back in front of them on Facebook and Instagram, usually for less than LinkedIn charges per view. Set the campaign up to optimise for a tested website conversion, such as a completed diagnostic or a booked call, not traffic or engagement. Our Facebook retargeting setup guide for B2B walks through it.
03Write for one buyer, at one moment
Finance services are bought at moments: a funding round, a sale, a bank asking for forecasts, a finance director handing in their notice. Ads that speak to the moment get read. Ads that describe your firm get scrolled past. Compare these:
Trusted financial advice for growing businesses. Experienced team, tailored service. Get in touch today.
Raising in the next 12 months? Investors will ask for a forecast you can defend line by line. Take the 6-question readiness check and see where you stand.
Example ads written for this guide.
Ad B speaks to a founder with a deadline and a fear they recognise, and it offers them something useful instead of a meeting. That's close to how the fractional CFO launch in our case studies worked: every ad was aimed at startups getting ready to raise money, the point at which a founder suddenly realises their numbers need to be in order.
Start by matching each service to the person who hires you, the moment they need you and an offer that fits that moment:
| Type of firm | Who hires you | The moment they need you | An offer that fits |
|---|---|---|---|
| Fractional CFO or outsourced FD | Founder or MD | Getting ready to raise, or the business has outgrown the bookkeeper | Investor-readiness checklist |
| Finance consultancy | FD or CFO at a mid-sized firm | Reporting takes too long, or a systems change is coming | Finance function health check |
| Accountancy firm adding advisory or CFO services | Owner-managers, including existing clients | Growth has made the numbers harder to read | Short quiz: do you need a CFO yet? |
| Tax specialist for business owners | Owner-manager | Profits are up, or a sale or restructure is on the horizon | Eligibility check, for example for R&D tax relief |
| Commercial finance adviser | MD or FD | Needs funding for growth, equipment or an acquisition | Funding readiness check |
| Valuation adviser | Owner thinking about exit or succession | An approach from a buyer, or planning to step back | Guide: what drives the value of a business like yours |
Table written for this guide as a starting point. Replace it with what you hear from your own best clients.
04Offer something useful before you ask for a call
"Book a free consultation" is a big ask from someone who has never heard of you. It means a call with a stranger about their finances, and probably a sales pitch. Cold audiences ignore it, the ad gets blamed and the firm decides ads don't work.
A short diagnostic, a checklist or a guide is a much smaller ask. The prospect gets something useful straight away, and you learn who they are and how ready they are. When they do book a call, there's something concrete to talk about: their result. Here's the shape of one I'd test:
The finance health check: six questions, two minutes
- Six questions about how the business reports, forecasts and plans cash
- A result page that shows where they stand and what to fix first
- A one-click link to book a call about their result, right there on the page
- A follow-up email that refers to their answers, not a generic "thanks for downloading"
- A notification to the partner the same day, so warm leads don't sit until Monday
Example offer written for this guide. It should be useful even if they never book a call. That's the price of their email.
Show people what they'll get before they start. In the finance consultancy case study, plain screen recordings and Loom videos walking through the quiz did that job: a sceptical, senior audience could see exactly what was on the other side of the click. Keep the direct "book a call" for people who already know you: retargeting audiences, and Google searchers who are actively looking.
The lead generation playbook for accountants and professional services firms covers diagnostic tools and advertorials in more detail.
05Track every lead to a signed retainer
A form fill isn't a client. If your reporting stops at leads, you'll end up rewarding the campaign that produces the most downloads, which is rarely the one that produces retainers. Here's what complete tracking looks like:
- Ad click
- Diagnostic or guide
- Lead in your CRM, with its source
- Booked call
- Proposal
- Signed retainer
- Capture the source on every lead. The ad platform, campaign and offer should land in your CRM with the contact, so you never have to guess.
- Connect your CRM to the ad platforms. Send booked calls and signed clients back to LinkedIn and Google as conversions, so they learn who becomes a client, not just who fills in a form.
- Record proposal value and retainer length. A client on a monthly retainer is worth far more than the first invoice. Judge campaigns on that.
- Review over quarters. Trust-led sales take time. Look at pipeline and signed clients over a sensible period, not what closed this week.
Retainers change the maths in your favour. In the fractional CFO case, the 7.5X ROI was measured on the initial spend, and it keeps growing because those clients stay on monthly. If GA4 is crediting your best leads to "direct", read why LinkedIn conversions show as direct traffic.
06Common mistakes finance firms make with ads
Asking cold strangers to book a call
Nobody books a finance conversation with a firm they've never heard of. Offer something useful first.
Sounding like every other accountant
"Trusted advisers for growing businesses" tells the buyer nothing. Name the buyer, the moment and the problem.
Hiding the partner
Finance is bought from people. Logo ads and stock photos don't build the trust a partner's face and opinions do.
Targeting "finance professionals"
Broad job functions reach junior staff who will never hire you. Use job titles at companies of the right size and sector.
Running Google without negative keywords
Finance terms attract job hunters, trainees and people doing their own tax. Use our free list for professional services firms.
Measuring leads instead of retainers
Downloads are easy to produce. Report booked calls, proposals and signed clients from your CRM.
Giving up after a month
Trust-led sales take longer than that. Judge a test over a quarter.
Leaving LinkedIn Audience Expansion on
It quietly widens your audience beyond the companies and job titles you chose. Switch it off.
07What this looks like for real finance firms
The team were burning hours on cold email to senior finance roles, and reply rates kept dropping. We stopped the cold outbound and ran LinkedIn Ads to a quiz tool instead, so the funnel filtered out time-wasters before any call was booked. Read the case study →
A brand new service with no track record and no existing demand. We ran LinkedIn Ads to founders and finance directors, aimed at startups getting ready to raise, layered Google Ads on high-intent CFO searches and tightened the website so paid traffic also lifted SEO. Read the case study →
Two anonymised client engagements. They show what's possible, not a prediction for your business.
08What it costs, and the DIY option
Working with usEvergreen Growth costs from £1,250 a month + VAT to manage one ad platform. Ad spend is separate and paid directly to the platform, from £500 a month per platform. Rolling monthly, 7 days' notice, no setup fee.
The full breakdown is on our pricing page. Before you spend anything, work out what one client is worth to you over the life of their retainer. That tells you what you can afford to pay to win one.
Frequently asked questions
Are LinkedIn ads worth it for a fractional CFO firm?
Usually, yes, because one client on a monthly retainer is worth a lot and LinkedIn lets you reach founders, MDs and finance directors at the exact company sizes and sectors you want. It works best when the partner is visible in the ads and the offer is something useful, not a cold request for a call. For one accountancy firm launching a fractional CFO service from scratch, LinkedIn and Google together produced 80+ leads in the first 6 weeks and a 7.5X ROI on the initial spend, which keeps growing as clients stay on retainer.
How long until finance firms see results?
Leads can arrive within weeks. In our two finance case studies, one firm had 80+ leads in its first 6 weeks and the other booked 24 qualified sales calls in 8 weeks. Signed retainers take longer, because finance decisions are made on trust and often wait for the right moment. Judge a campaign on calls, proposals and signed clients over a quarter, not on what closed this month.
What budget is needed?
Work it back from what one client is worth to you over the life of the retainer, not from a platform's suggested budget. Ad spend starts from £500 a month per platform, and for LinkedIn we recommend £1,500+ a month of media for a meaningful test. That's a recommendation, not our minimum. Evergreen Growth costs from £1,250 a month + VAT to manage one ad platform. Ad spend is separate and paid directly to the platform, from £500 a month per platform. Rolling monthly, 7 days' notice, no setup fee. So the smallest all-in month with us is about £1,750: the £1,250 fee + VAT plus £500 of ad spend.
Google or LinkedIn for a finance firm?
Google catches people already searching for the service, but for niche finance services that's a small number of people. LinkedIn reaches the many business owners who have the problem but have never searched for it. Most finance firms do best with both, each judged on its own numbers, with Meta retargeting keeping you in front of the people who visited.
Should finance firm ads ask people to book a call?
Not for cold audiences. Someone who has never heard of you won't book a call with a stranger about their finances. Offer something useful first, such as a short diagnostic, a checklist or a guide, then make the call the obvious next step on the result page. Keep the direct booking option for people who already know you, such as retargeting audiences and Google searchers.
How do I stop the wrong people clicking my Google ads?
Use negative keywords to block searches from job hunters, trainees and people looking for government self-service or help with personal tax, and check the search terms report every week. We've published a free negative keyword list for professional services firms you can copy into Google Ads.
Can I run finance firm ads myself?
Yes, if your budget is small and you'd rather learn than hire. The B2B Ads Kickstart is our step-by-step course for running your first LinkedIn or Meta campaign, with an AI coach at each step. Step 1 is free. The full course is £97 (inc. VAT), one-off.
Want more clients than referrals alone can bring?
I'm James Green, founder of Evergreen Growth. On the call we'll look at the clients you want, what one is worth to you and where your work comes from now, then tell you whether LinkedIn, Google or both make sense. If there's a fit, you'll get a proposal.
