What this post covers: Mike Michalowicz’s Profit First method flips the standard accounting formula so that profit is extracted before expenses are paid. This article breaks down the system, the behavioural science behind it, and what 350,000 companies have proved about growth. It draws on Dominic Monkhouse’s interview with Mike on the Scale to Win podcast and Dominic’s own experience turning around a business that was losing £65,000 a month.
The short answer: Profit First replaces Sales − Expenses = Profit with Sales − Profit = Expenses. Open five bank accounts. Allocate a fixed percentage of every deposit to profit, owner’s compensation, and tax first. Run the business on what’s left. Start at 1% to 2% and ratchet up quarterly. Data from 350,000 companies shows profit-first businesses grow faster than those that reinvest everything.
In 2008, I walked into IT Lab when it was losing £65,000 a month. We had 90 days to get to break even before the money ran out. The business had a profit problem. Not a growth problem. Not a strategy problem. A profit problem.
We had to do three things at once: cut costs, raise prices by 50%, and sell harder. I found £25,000 a month of recurring costs for internet circuits that clients had cancelled on us but we’d never cancelled on our vendors. We lost one customer out of the entire book. One. Red Lorry Yellow Lorry, a digital agency. Everyone else stayed.
That experience taught me something that Mike Michalowicz spent years turning into a system called Profit First. Profit isn’t what’s left over at the end. Profit has to come first.
I spoke with Mike on the Scale to Win podcast. He’s the author of Profit First, Clockwork, and Fix This Next. He built two successful tech companies before losing everything as an angel investor. He rebuilt from scratch by writing books about the things he didn’t understand. It was one of the most useful conversations I’ve had about the mechanics of running a financially healthy business.
Is the standard accounting formula working against you?
Yes. The textbook formula (Sales − Expenses = Profit) puts profit last. When something comes last, it becomes insignificant. The formula is logically correct but behaviourally toxic.
As Mike put it on the podcast: “I would never say I love my family, that’s why I put them last. Yet that’s what we say about profit.” We call it the bottom line, the final take, the year-end number. All of that language means: not yet.
A study by a US bank, later replicated globally, looked at 30 million small businesses (defined as under $25m revenue) and found that 83% were surviving cheque to cheque. Not occasionally short. Structurally unable to pay tomorrow’s bills from today’s cash. The same pattern held across nearly 200 million small businesses worldwide.
That’s not a fluke. That’s a formula producing exactly the result it was designed to produce.
What does Profit First actually do?
Mike’s formula flips it: Sales − Profit = Expenses.
As revenue comes in, a predetermined percentage is immediately moved to a separate profit account and hidden from the operating business. You then run the business on what’s left.
It sounds almost too simple. But the behavioural logic is solid.
The average business owner doesn’t read their P&L, their cash flow statement, or their balance sheet, or the seven cash-flow levers that show where cash is getting stuck. They do what Mike calls “bank balance accounting”: they log into their account, see a number, and spend accordingly. If there’s money there, they find something to spend it on. If there isn’t, they panic.
Profit First is designed around this reality, not against it. It works with how people actually behave, rather than how accountants wish they’d behave.
“Every week I sit with founders who tell me they’ll take profit ‘when the time is right.’ It’s the same pattern I saw at IT Lab when we had 90 days of cash left. The time is never right. You have to force it. Founders who ring-fence their profit make sharper decisions than founders who keep telling themselves next quarter will be different.”

Why do your expenses always match your revenue?
Parkinson’s Law guarantees that expenses rise to consume whatever revenue is available. Not through recklessness, but through predictable human behaviour. The Profit First fix is structural: separate your money into dedicated accounts before you can spend it. Here’s how the five-account system works and what the allocations look like in a real business.
Because of Parkinson’s Law: as supply increases, consumption rises to meet it. Expenses expand to fill whatever revenue is available. Not because founders are reckless, but because that’s how humans behave around resources.
Put one chocolate chip biscuit in front of someone, they eat one. Put fifteen in front of them, they eat more than one.
Cash works exactly the same way. Give a business owner £1,000 and they’ll find a way to spend it. Give them £10,000 and they’ll find a way to spend that too. This is why, as revenue slowly creeps upward, expenses have a strange tendency to follow. It’s not carelessness. It’s Parkinson’s Law in action.
The five-account system Mike designed works with this, not against it. Set it up once and the allocation happens every time money comes in.
The five accounts
The income account is a depository only. All revenue lands here. Nothing is spent from it directly. Think of it as a serving tray, not a spending account.
The profit account receives a percentage of every deposit, immediately. This is the reward for taking risk as a shareholder. It comes out quarterly as a distribution, not a salary.
The owner’s compensation account is separate from profit. This is what you pay yourself for working in the business. If you had to hire someone to replace yourself, what would you pay them? That’s your wage. You live off this, not off profit.
The tax account reserves a percentage for your personal and corporate tax liabilities. This one matters more than people expect. As Mike said, every country in the world has a government that will “stick its long sticky fingers in your business and pull money out.” Ring-fence it or you’ll be scrambling when the bill arrives.
The operating expense account is what’s left. That’s your budget for running the business. Not the total. Not the income. What’s left after everything else has been allocated.
What does this look like in practice?
If £1,000 comes into your income account and you allocate 20% to profit, 30% to owner’s compensation, and 20% to tax, you have £300 left to operate your business. You don’t have £1,000. You have £300. That shift in what’s truly available changes everything about how you make decisions.
| Account | Allocation | From £1,000 |
|---|---|---|
| Profit | 20% | £200 |
| Owner’s compensation | 30% | £300 |
| Tax reserve | 20% | £200 |
| Operating expenses | 30% | £300 |
Your numbers will be different. The point is the principle: allocate before you spend.
For UK businesses, the tax reserve needs to cover Corporation Tax (currently 25% for profits above £250k, with marginal relief for smaller profits), plus any VAT and PAYE obligations. Talk to your accountant to set the right percentage for your situation. Most UK business banks now let you open multiple accounts with minimal friction.
I scaled two companies to £30m. Every week, I'll show you how.
Start at 1%. Ratchet from there.
Start at 1% or 2% of revenue and ratchet up quarterly. The barrier isn’t the system. It’s the assumption that you need to go from zero to 30% profit overnight. You don’t.
Mike’s advice: start at 1% or 2% profit allocation and slowly grow it. The constraint will force innovation. The business will adapt. The question you’ll ask, “how do we operate on less?”, is one of the most valuable questions you can put to your team.
I’ve seen this work with pricing too. New Signature, a client of mine, were unhappy with their margins. I asked: do you think you could get 1% more? They said maybe. So they added 1% that month. The following month I asked: did anyone notice? The sales team had to look it up. No customers complained. So they did it again. Then again. Twelve months later, they were up 12%. Then they got bullish and moved to 1.5% per month. Two years on, their pricing was in a completely different place. Nobody left. They went on to sell the business.
The Profit First principle is identical. You’re not trying to transform overnight. You’re ratcheting, slowly, towards a business that generates real cash for its owners.
A husband and wife who’d run a horse breeding business in Canberra, Australia for twenty years proved this works even in industries with a reputation for being unprofitable. After two decades without making a penny, they implemented Profit First. Within a year they were profitable. Not just on paper. With actual cash. Forced to operate on less, they found ways to cut their feed costs and position their horses at a higher premium. Their marriage improved too. Just because the industry struggles doesn’t mean you have to struggle in that industry.
Do profit-first businesses actually grow faster?
Yes. Data from over 350,000 companies tracked by Mike Michalowicz’s team shows that profit-first businesses outgrow those that reinvest everything. That’s the exact opposite of what conventional wisdom predicts.
“We’re reinvesting our profits” is the standard line from founders who want to justify thin margins. But Mike is blunt about what that actually means: “Plough back and reinvest. It simply means you spent the money.” If the money is distributed to a shareholder, it’s profit. If it’s spent on anything else, it’s an expense. It was never profit.
When businesses plough back, they tend to spend imprecisely. Facebook ads because everyone else is doing it. A new hire who feels essential. A tool they might use one day. With no constraint, there’s no discipline.
When businesses take profit first, they operate with scarcity. The question becomes: of everything we could spend money on, which one thing actually works? That forced selectivity produces better ROI, fewer wasted experiments, and faster compounding growth.
Forced scarcity makes you pick the right things. I’ve seen this play out with a client who put several million pounds in the bank and then we had a conversation about what would have been different if that cash wasn’t there. One director said: “I’d probably have got rid of my poor performers quicker. And I might not have hired somebody this quarter.” Exactly right. The cash cushion was making them lazy.
Does your business have a hierarchy of needs?
Every business has five needs that must be met in order: sales, profit, order, impact, and legacy. Skip a level and the structure crumbles. Mike Michalowicz formalised this in Fix This Next as the business hierarchy of needs.
The five levels are:
- Sales: the creation of cash
- Profit: the extraction of cash for stability
- Order: building systems so the business can run without the owner carrying it
- Impact: transforming the client experience
- Legacy: the continuance of the business beyond the founder
I see this hierarchy play out constantly when I’m running the target operating model with clients. So often, the biggest constraint in the business is new customer acquisition. If we can fix that, everything gets easier: they can generate money, they’ve got assets, they’ve got a business that flows, and then they need systems.
Where I’d push back on Mike is on Impact. He places it fourth, after Order. In my experience, you can’t wait that long. Fixing the client experience is something you have to do alongside sales, profit, and systems. It’s not a separate stage you graduate to. If your clients are having a poor experience while you’re busy building internal systems, you won’t have clients left to systematise around.
What I see constantly is founders who’ve spent fifteen or twenty years in a business and arrive at retirement age with something worth nothing. Because without them, there’s no business. They never climbed to the Order level. They never made themselves replaceable. As Mike put it: “What buyer in the right mind would say, the day you leave your business the business collapses. I want in?”
If you can’t extract yourself and have the business continue, you don’t have an asset. You have a job you can’t quit.
How do you validate an idea before building it?
Ask for a deposit before you build anything. If people pay, you have something. If they don’t, you don’t. As Mike put it: “People speak the truth not through their words, but through their wallets.”
He spent years pitching new products to people he knew, hearing “I’d buy that all day long,” investing months building the thing, then coming back to hear “actually, not right now.” People lie in conversation. Not maliciously. Social norms push us to be encouraging and supportive. Nobody wants to tell someone their idea is bad.
The fix is simple. Not a conceptual question. Not a survey. A deposit. Real money. Mike calls it the wallet test, and it saves more time than any focus group ever will.
How to set up Profit First today
Open five accounts at your bank. Most UK business banks will do this for a single business entity. Label them: Income, Profit, Owner’s Compensation, Tax, Operating Expenses.
Set small percentages for each non-operating account. Start at 1% for profit, a conservative figure for owner’s comp, and 15 to 20% for tax (check with your accountant).
Every time money comes into the income account, allocate by those percentages immediately.
For the profit and tax accounts, make them hard to access. No app access. No debit card. Ideally at a different bank. Mike drives to his. Deliberately. As he put it: “I’m protecting myself from myself.”
Distribute the profit account quarterly. Not monthly. Quarterly. It arrives as a bonus rather than something you mentally budget against.
Then adjust your operating expense budget to match only what’s in that account. Not what came in. Not what you think should be available. What’s actually there.
The constraint will feel uncomfortable at first. That discomfort is your business telling you something needs to change. And that’s exactly the conversation you should be having with your team.
Frequently asked questions
How much profit should I allocate first?
Start at 1% or 2% of revenue. The point is to begin, not to hit a target percentage on day one. Once the business adapts to operating on slightly less, increase the allocation by a percentage point. Mike Michalowicz recommends ratcheting up quarterly. In the example he gave on the Scale to Win podcast, he allocated 20% to profit on £1,000 of revenue, but that’s a mature implementation. A business that has never taken profit should start small and build the muscle over six to twelve months. His data from 350,000 companies shows the average business reaches a healthy profit allocation within two years of starting the system. The discomfort of operating on less is temporary. The discipline compounds. Every founder I’ve coached through this looks back a year later and wonders why they waited so long.
Does Profit First work for service businesses?
Yes. Service businesses are often the best candidates because they have fewer hard input costs and more flexibility in how they allocate revenue. The five-account structure applies whether you sell time, expertise, or a mix. The most common mistake service founders make is treating their own salary as a profit distribution. It isn’t. Owner’s compensation is what you’d pay someone else to do your job. Profit is the shareholder return on top of that. Many service business owners conflate the two and end up thinking they’re profitable when they’re really just paying themselves from revenue. Mike Michalowicz’s research across 350,000 companies spans every industry. Service businesses, where costs are largely people and overhead, often adapt fastest once the accounts are separated. Because there are fewer fixed input costs to renegotiate.
What if my business genuinely cannot afford to take any profit?
That’s the signal Mike says you need to hear. If you can’t set aside 1% of revenue as profit, your business has a structural problem. Diagnose it as one of three things: a pricing problem (your margins are too thin), a cost problem (overhead you can’t justify), or a revenue problem (not enough coming in). Use the 1% test as the diagnostic. At IT Lab I faced all three simultaneously. Losing £65,000 a month with 90 days of cash left. We cut £25,000 a month in costs, raised prices by 50%, and sold harder in parallel. No time to sequence them. Most businesses aren’t in that position, which is why they delay. Don’t. Diagnose the constraint, fix it, and start the allocation at 1%. The discomfort is the signal. Not the reason to stop.
Can UK businesses set up Profit First accounts easily?
Most UK business banks allow multiple accounts under one entity. Starling, Tide, and the major high street banks all support this. The key is separating the profit and tax reserve accounts from your everyday operating account. Some founders open the profit and tax accounts at a completely different bank with no online access, which adds friction that prevents impulsive spending. Mike drives to his profit account’s bank deliberately to make withdrawals harder. For UK businesses, Corporation Tax sits at 25% for profits above £250,000 with marginal relief below that threshold, so your tax reserve percentage needs to reflect your actual liability. Talk to your accountant about how Corporation Tax, VAT, and PAYE obligations should factor into the right percentage for your situation.
What is the business hierarchy of needs?
The business hierarchy of needs is a framework from Mike Michalowicz’s book Fix This Next. It identifies five levels every business must address in order: Sales (creating cash), Profit (extracting cash), Order (building systems), Impact (transforming the client experience), and Legacy (ensuring the business outlasts the founder). Like Maslow’s hierarchy, lower levels must be satisfied before higher levels become meaningful. In my experience coaching more than 200 founder-CEOs, the biggest constraint is usually new customer acquisition. Fix that and everything flows. Where I push back on Mike is on Impact. You can’t wait until systems are perfect before fixing the client experience. Customers won’t hang around while you build internal processes. But the core principle holds: trying to build a legacy while the business bleeds cash is the equivalent of worrying about self-actualisation while you can’t breathe.

What should you do next?
If this post has annoyed you slightly, good. The issue is probably not effort. It is design. The business is asking you to carry decisions, standards and exceptions that should now belong inside the team.
The goal is not to disappear. The goal is to build a company where your best work is not dragged back into every operational tangle.
That is the point. Scaling is not adding more people around the same bottleneck. It is rebuilding the business so the bottleneck is removed.
