You can build a product. You can sell it. You can hire a team, close a round, and talk a big customer off the ledge at 11pm on a Sunday.

‍

So why does the finance side still feel like a language you half-speak?

‍

Here's the uncomfortable bit: most founders don't struggle with finance because they're bad at it. They struggle because they can't see the gap. And the data backs that up. In one recent study, only 24% of small business owners believed they lacked the financial skills their business needed — yet the accountants working with those same owners told a very different story, reporting that a large share of clients were making decisions based on misinformation picked up from social media and casual conversation. The problem isn't a lack of intelligence. It's a lack of visibility into what you don't know.

‍

And it's expensive. A Companies House-based analysis this year found that nearly two in five new UK businesses launched in recent years have already collapsed. Not because the ideas were bad. Because the numbers underneath them quietly stopped working — and nobody was watching the right ones.

‍

So Do You Actually Need a CFO?

‍

Let's kill the question in its current form, because "do I need a CFO?" is the wrong question.

‍

The right one is: is anyone in my business asking CFO-level questions right now?

‍

Questions like:

• What does my burn rate actually imply about the next 18 months, not the next 18 days?
• Is my pricing supporting the business I want to build, or quietly capping it?
• If my biggest customer paid 30 days later than promised, would I feel it? Would I survive it?
• What's the one number that, if it moved 10%, changes everything?

If nobody is sitting with those questions — not your bookkeeper, not your accountant, not you at midnight — that's the gap. And the gap doesn't announce itself. It shows up as a missed runway pinch, a fundraise that stalls in diligence, or a hire you couldn't really afford.

‍

Your Accountant Is Not Your CFO (And That's Fine)

‍

This trips up more founders than almost anything else, and it's worth being precise about, because the two roles get sold to you as if they're interchangeable. They aren't.

A traditional tax practice does a specific, essential job: filing your accounts, keeping HMRC happy, closing the year, making sure you don't overpay or trip a deadline. If that's done well, it's genuinely valuable. Keep it.

‍

But look at what that job actually is. It's compliance, and compliance looks backwards. It takes a year that has already happened and writes it down correctly. The very best tax accountant in the country can produce a flawless set of statutory accounts and still not be able to tell you whether you can afford your next hire — because that was never their job, and answering it well takes a completely different kind of experience.

‍

Here's the part that matters most for a young founder, and the part nobody says out loud: most traditional tax accountants have never run the kind of business you're running. Many have spent their entire career inside a practice, doing tax — never sitting inside a growing company, never sweating a payroll they had to make on Friday, never watching a margin erode in real time while everyone around them insisted revenue looked fine. They know the rules of the return. They don't necessarily know the rhythm of your sector, the way cash actually moves through a SaaS book versus a hospitality one, or which "healthy" number is about to bite you.

‍

One tells you what happened. The other tells you what to do about what's going to happen.

‍

That second job — finance leadership — is a different discipline built by different people. At xpand it's built by operators: our anchor experience is five years running finance for a brewing group as it scaled from around £2m to £15m across ten companies and three countries. That's not a tax qualification talking. That's someone who has actually been in the passenger seat while a business grows faster than its systems, and knows which warning lights matter. Both matter. They are not the same job, and expecting one person — least of all a once-a-year, tax-only relationship — to do both is how founders end up with tidy accounts and no idea whether they can afford next quarter.

‍

There's a wider skills story here too. A Xero study of 16–21 year olds found 37% cited inadequate financial knowledge as a barrier to starting a business, and 61% felt entrepreneurship was really only open to people with existing wealth or networks. The finance confidence gap doesn't magically close when you become a founder. It just gets more expensive.

‍

When the Gap Actually Bites

‍

You don't need CFO-level thinking every day. You need it at the moments that compound:

‍

Before a raise. Investors run serious diligence. A model built on top-down hope, a cap table with surprises in it, or metrics you can't defend on the spot — any one of these can turn a "yes" into a "let's revisit in six months." Your tax accountant will not build that model or sit across the table defending it. That's a fractional finance job.

‍

When cash gets tight. The founders who get caught out aren't negligent. They're busy building and selling and firefighting, and finance slips to the background until it can't. This is where late payment quietly does its damage — QuickBooks found 62% of UK small businesses are currently owed money on unpaid invoices, an average of £21,400 each. A simple rolling cash flow forecast turns panic decisions into planned ones. Nobody files that in your year-end accounts.

‍

When you're about to spend big. A senior hire. A new office. A marketing bet. These are the decisions where CFO-level thinking pays for itself many times over — before you commit, not in the post-mortem.

‍

And this is the deeper reason the gap is so dangerous: it hides until it's fatal. When CB Insights looked at 400+ startups that shut down, 70% had "run out of capital" — but the report was blunt that running out of cash "is almost always the final cause of death, not the root problem." The root problem was a decision made months earlier, on a number nobody was watching. Most companies don't fail because the numbers were bad. They fail because the numbers were late.

‍

The Part Founders Get Wrong: It's Not Full-Time or Nothing

‍

Here's where most founders freeze. They assume the choice is between muddling through alone and hiring a full-time finance leader — a £50k–£150k-a-year commitment before that person has delivered a single insight.

‍

For a pre-seed, seed, or early scale-up business, that's a false choice. You don't need someone in the building five days a week. You need someone who thinks like a CFO a few days a month: someone who owns a model investors believe, gives you real visibility on cash and runway, and acts as a sounding board on pricing, hiring, and the trade-offs that keep you up at night.

‍

That's the whole idea behind fractional finance. Finance leadership, without the headcount. Senior thinking, scaled to where your business actually is — not where a full-time salary says it should be. And crucially, it sits alongside your accountant, not instead of them: they keep the compliance clean, we make sure someone is finally reading the road ahead.

‍

So, Where Do You Start?

‍

Start by being honest about the gap. Not "am I bad at finance?" — you're not. But: is anyone asking the bigger questions, and would I know if the answers were bad?

‍

If reading this made you think "that's us right now," that's not a failure. That's clarity. And it's a much cheaper place to fix things than mid-raise or six weeks from empty.
