When to hire your first finance person
There's a moment in most businesses when you realise your spreadsheet isn't cutting it anymore.
Maybe you're three months behind on reconciling the bank. Maybe you've just spent an entire Sunday trying to figure out if you can afford to hire someone. Maybe HMRC sent a letter and you genuinely don't know if you should be worried or not.
That moment usually prompts the question: do I need to hire someone for this?
And then immediately after: what kind of someone? A bookkeeper? An accountant? One of those FD people everyone keeps mentioning?
Here's the thing. Most businesses don't need a Finance Director at £100k+ when they're turning over £700k. But they also can't keep winging it with a shoebox of receipts and a founder who hates numbers.
The answer sits somewhere in between. And knowing where your business sits on that spectrum matters more than you'd think.
The Problem With Generic Advice
If you google "when to hire a CFO," you'll find all sorts of rules of thumb. Some say £1 million revenue. Others say £10 million. Some say "when you're raising funding." Others say "before you start scaling."
Helpful, right?
The truth is there's no magic revenue number. I've worked with businesses at £3 million who desperately needed finance support, and others at £8 million who were doing just fine with a good bookkeeper and some fractional help.
What matters is what's happening in your business, not what's written on someone else's blog about Silicon Valley startups.
The Real Signs You Need Finance Support
Forget revenue milestones for a minute. Here's what actually tells you it's time:
You're making decisions based on guesswork, not data
Can you answer these questions right now, without checking anything:
How much cash will you have in three months?
Which parts of your business are actually profitable?
Can you afford to hire someone next month?
What happens if that big invoice gets paid late?
If the answer is "I think so?" or "probably?" or "I'd need to check about fifteen different places," then you need help. Because those questions shouldn't require detective work.
According to Xero's 2025 research, 38% of UK small business owners don't even know if their business was profitable last month. That's not a systems problem. That's a finance capacity problem.
Your bookkeeping is always behind
Three weeks behind is annoying. Three months behind is a problem. Six months behind means you're flying completely blind.
And here's the bit that catches people out: you can't make strategic decisions with old data. If you're looking at September's numbers in February, you've already missed whatever was actually happening in your business.
The British Business Bank's 2025 report found that SME investment continues to be low, with high credit costs and risk aversion as key factors. Part of that risk aversion comes from businesses not having current financial data to present. Banks want to see clean books and up-to-date management accounts. Spreadsheets from three months ago don't inspire confidence.
You're spending your weekends doing finance admin
Founders should be thinking about strategy, not categorising transactions.
If you're regularly spending Saturday mornings reconciling the bank or Sunday evenings trying to figure out your VAT return, that's not just inefficient. It's expensive. Your time has a value, and finance admin probably isn't the highest use of it.
One of my clients calculated she was spending about 8 hours a month on bookkeeping. At her day rate, that was costing the business £3,200 in opportunity cost. A bookkeeper cost £800 a month. The maths was pretty clear.
You're about to do something big
Hiring your first employee. Taking on a commercial lease. Applying for funding. Launching a new product line. Expanding into a second location.
All of these decisions have financial implications that go beyond "can we afford it right now?" You need to understand cash flow impact, break-even analysis, scenario planning. That's hard to do when you're also trying to deliver to clients and keep the business running.
According to UK Finance's 2025 Q3 Business Finance Review, gross bank lending reached £62 billion in 2024. Challenger banks accounted for 60% of total lending to SMEs. But here's what they don't tell you: getting that lending requires proper financial documentation. Banks want to see realistic forecasts, clean historical data, and evidence you understand your numbers.
You're VAT registered and it's causing you actual stress
VAT registration is brilliant for cash flow. It's also a massive administrative burden if you're doing it yourself.
From April 2026, Making Tax Digital for Income Tax Self Assessment (MTD ITSA) will require digital record-keeping for self-employed individuals and landlords earning over £50,000 (dropping to £30,000 in 2027). That means proper systems, not spreadsheets.
If the thought of your next VAT quarter makes you want to hide under your desk, it's time.
HMRC keeps writing to you and you don't understand why
This one should be obvious, but it's worth saying: if you're getting letters from HMRC and you're not 100% sure what they're about or what you need to do, get help immediately.
HMRC penalties for late VAT returns follow a points-based system. Companies House fines start at £150 and can reach £1,500. These aren't small costs, and they're completely avoidable with proper financial administration.
What Level of Support Do You Actually Need?
Right. So you've decided you need help. Now what?
The finance world is full of job titles that sound similar but mean completely different things. Here's a rough guide to what each level actually does:
Bookkeeper (£20-55/hour, or £120-500/month retainer)
This is day-to-day financial admin. Recording transactions, reconciling bank accounts, processing invoices, managing expenses, preparing for VAT returns.
You need a bookkeeper if:
Your transactions are piling up
Your bank reconciliation is always behind
You're spending too much time on admin
Your records aren't organized enough for year-end
You're VAT registered and drowning in paperwork
You don't need a Finance Director for this work. You need someone who's good at systems, detail, and keeping things current.
Finance Manager / Analyst (£40-60k salary, or £450-500/day fractional)
This is the middle ground. Someone who can produce management accounts, build forecasts, analyse performance, spot patterns in your data.
You need this level if:
You want to understand which parts of your business are profitable
You're making investment decisions and need financial modelling
You need monthly reports that actually tell you something useful
You're preparing for funding and need forecasts
Your business is complex enough that "income minus expenses" doesn't cut it anymore
Finance Director / CFO (£80-120k salary, or £800+/day fractional)
This is strategic finance leadership. Someone who sits at the table with you, challenges your thinking, helps with planning, speaks to investors or banks, builds financial strategy.
You need this level if:
You're raising funding
You're planning an exit
Your board expects proper financial reporting
You're making big strategic decisions (acquisitions, major expansion, new business lines)
Your business has reached the point where financial strategy matters as much as operational delivery
According to multiple industry reports, fractional CFO demand surged 103% in 2025-2026. The number of fractional CFO professionals grew from 2,000 in 2022 to 110,000 by late 2024. There's a reason for that explosion: businesses are realizing they can access strategic finance expertise without the £150k+ permanent hire cost.
The Bit No One Tells You: You Probably Need More Than One Thing
Here's where it gets interesting. Most businesses don't need just one level of finance support. They need multiple.
You might need someone to keep your books current (bookkeeper) AND someone to produce monthly management accounts (analyst) AND someone to help with your three-year plan (FD).
That used to mean hiring three people. Which is why businesses either tried to make do with one overworked person doing all three jobs badly, or they just didn't bother until they were much bigger.
This is where the fractional model actually makes sense. You get bookkeeping support 2 days a week, analyst support 1 day a week, and FD-level input 2 days a month. Total cost: £6-7k per month. Compare that to £200k+ per year for three permanent hires.
UK SMEs using fractional finance teams report 40-60% cost savings and 340% ROI within 6 months, according to 2025 industry data.
How to Know What You Need Right Now
If you're still not sure, try this:
List every finance task your business needs. Include everything: bank reconciliation, invoicing, chasing payments, VAT returns, management accounts, cash flow forecasting, board reporting, strategic planning, fundraising prep, scenario modelling.
Mark each task as:
Daily/weekly (operational)
Monthly (reporting and analysis)
Quarterly/annual (strategic)
Now estimate hours per month for each. Be honest. Include the time currently spent by you, your co-founder, your office manager, whoever's doing bits of it.
This exercise usually reveals two things:
You're doing way more finance work than you realized
You need different levels of support for different types of work
Most businesses at £500k-£2m revenue need about 20-30 hours per month of finance support across all levels. That might be 12 hours bookkeeping, 8 hours analyst work, and 6 hours FD-level. Those proportions will shift as you grow.
When NOT to Hire
It's also worth knowing when it's too early.
If you're still in the first year, turning over less than £100k, and can genuinely stay on top of things yourself, you probably don't need to hire yet. Get good systems in place (proper accounting software, not spreadsheets), and keep your records current.
If your main issue is that you don't understand what your accountant is telling you, you might not need more finance support. You might just need better communication from your existing accountant.
If you're hoping a finance person will magically fix all your business problems, hiring won't help. Finance support helps you make better decisions. It doesn't make the decisions for you.
A Better Question Than "When"
Instead of asking "when should I hire finance support," try asking "what decisions am I making without proper financial information?"
If you're winging it on whether you can afford that new hire, guessing whether your pricing is sustainable, or crossing your fingers that cash flow will work out, those are decisions that deserve better data.
The cost of getting those decisions wrong is almost always higher than the cost of getting proper finance support.
One more thing from the 2025 ONS Business Insights survey: 18% of businesses cite falling demand as their main concern, while 15% cite taxation. Meanwhile, 60%+ of UK small businesses are being paid late by bigger companies, costing them an average of £22,000 per year.
Those are the actual pressures on your business right now. Your finance function should help you navigate them, not add to them.
What This Actually Looks Like
Real example: I worked with a retail business turning over £2.5 million. They had a part-time bookkeeper (3 days a week, keeping records current) and an external accountant (annual accounts and tax).
What they didn't have: anyone looking at monthly performance, analysing which product lines were profitable, forecasting cash flow, or helping them plan for growth.
They brought me in fractionally, 2 days a month. Within three months we'd identified that one entire category of products was losing money once you properly factored in the full cost of goods and staff time. They killed that line, focused on what was profitable, and increased profit by 40% whilst working less.
They didn't need a £100k Finance Director. They needed 2 days a month of strategic finance thinking alongside their existing bookkeeping.
That's the model that works for most businesses between £500k and £5 million revenue.
The Bottom Line
You need finance support when you're making important decisions without proper information.
What level of support you need depends on what decisions you're making, how complex your business is, and how much capacity you have internally.
Most businesses need multiple levels of support, not just one.
And the cost of hiring too late is almost always higher than the cost of hiring too early.
If you're still not sure where you fit, that's actually a good sign it's time to have a conversation with someone who can help you figure it out.
