Do I need a CFO to manage a sale process?

You want your business viewed in the best possible light, not underselling and leaving value on the table. But here’s the crux: if there isn’t a CFO in place at least 18 months before conversations start and a price gets mentioned, both sides get nervous.

Eighteen months isn’t an arbitrary number. It’s roughly how long it takes to get twelve clean months of management accounts on record, a debt model that’s actually been stress-tested, and a story about the business that holds together under questioning. Get a CFO in place after the call comes in, and you’re building all of that on the buyer’s clock instead of yours, with a price already hanging in the air.

You’ve been managing the business up to this point

That’s both a blessing and a curse. The business, the product, the service, all of it is entirely dependent on you. That dependency costs you real value: no succession, no depth in the ranks, and a buyer prices that risk straight into the offer. But it also means you’re the best person to keep managing performance while somebody else manages the process. The naive first move is assuming those are the same job.

So you start pulling together numbers. Management accounts get dusted off. Your controller starts fielding data requests. You spend your evenings and weekends building a model, checking figures, prepping for the next call. It feels manageable, for now.

Reality check

A sale process is not a bigger version of your monthly board pack. It’s a forensic examination of your numbers by people whose job is to find reasons to pay you less, or walk away entirely. Running it on the side, with a team that’s never done this before, is how good businesses get bad outcomes.

Somebody also needs to set up and run the virtual data room. It’s not a small job, and a well-organised VDR reflects well on the business before a buyer’s team reads a single number in it. Get it wrong and you get death by a thousand questions, the same document requested three times, gaps that read as evasion rather than disorganisation. Your CFO navigates the business through that, and protects your time while they do it.

You’ve told the equity story perfectly — but who backs it up with numbers?

Your Head of Finance or FC will struggle with the peacocking that buyer presentations demand. You need somebody in that room who can talk about the business almost as well as you can, but from a financial angle: what the main value drivers actually are, why the margins are resilient, why the model shows genuine upside rather than a hopeful trend line. That’s not a reporting skill your existing team has ever been asked to use. It’s a CFO’s job, and it’s exactly the story a buyer’s due diligence team will spend weeks trying to pick apart.

If there’s debt in the business, someone needs to own the model properly

Buyers and lenders don’t evaluate one deal structure, they evaluate several — asset sale, share sale, earn-out — and expect covenant headroom and cash flow to flex under each one. A model built once for internal reporting can’t do that on demand. The check: ask whoever manages your debt model today how long it would take to re-run headroom under a different deal structure. If the honest answer is more than a day, the model isn’t deal-ready, and that gap either scares off a buyer or gets you into terms that quietly damage the business you’re selling.

The process is a full-time job, and so is running the business

Due diligence requests don’t arrive in a tidy batch; they trickle in for months, at short notice, needing figures cut a dozen different ways, and that unpredictability is exactly why they eat far more time than CEOs budget for. Your advisors are already busy preparing their own reports. If you’re doing vendor due diligence, you want somebody crawling over every line of it, making sure the numbers are presented in the best possible light before a buyer ever opens the file. Then real due diligence starts, buy-side, usually with a grimace, and you want that same person defending and protecting the numbers in your model, arguing every last point. Two different phases, two different jobs, and neither one happens on the side of running the business.

This is exactly where a fractional CFO earns their fee. It’s much easier to get that prep done with a variable cost, and a fractional CFO worth their salt will tell you honestly if you need a full-timer instead.
