Why Being Busy Doesn't Mean You're Making Money

The trap of high revenue, low margin — and a fencing business doing £50k/month in sales but losing £80k

You're swamped. Your phone's ringing, you've got three teams in the field, materials are flying out the door faster than you can order them, and your accountant keeps telling you that your revenue is "impressive." But here's the uncomfortable truth: you're working harder than you've ever worked, and your bank account is getting lighter every week.

This is the "busy but broke" trap, and it's destroying more UK trades and small businesses than any recession ever could. The danger isn't that you're not busy enough — it's that you're too busy doing the wrong work at the wrong margins.

The £50,000 a Month That's Burning Cash

Meet Gary. He runs a fencing business in Kent. By the numbers, he's crushing it: £50,000a month in sales, eight staff, three fully stocked vans, and a waiting list that would make most business owners smile.

But Gary's stress levels tell a different story. By month three of this "success," he's spent £80,000 more than he's earned. His bank balance is screaming, his suppliers are asking questions, and he's working seventy-hour weeks to keep up.

What went wrong? Gary confused revenue with profit.

His fencing installations were bringing in £50,000 a month. Sounds great. But his costs — materials, labour, fuel, vehicle maintenance, insurance, rent on the yard, software subscriptions — were closer to £48,000. And his overheads (the stuff that keeps the lights on whether you do one job or a hundred) were another £3,000.

That means Gary was making roughly 2-4% profit margin on his turnover. For every £50,000 in sales, he was keeping maybe £1,500 in actual profit — if he was lucky.

Gary's real numbers: Monthly sales £50,000 | Monthly costs £51,000 | Monthly profit: -£1,000 (or worse)

Except he didn't just make -£1,000 a month. He made -£1,000 a week in some weeks, because payments were sporadic, cash flow was lumpy, and his suppliers didn't wait for customers to pay him before demanding payment themselves.

Sound familiar? You might not be a fencing contractor, but if you're in the trades — plumbing, carpentry, electrical work, landscaping, construction — the shape of Gary's problem is probably creeping into your own business.

How to Spot the Signs You're Busy But Broke

The dangerous part about the busy-but-broke trap is that it doesn't announce itself loudly. It creeps up on you. Here are the warning signs:

1. Your team is growing, but your bank balance is shrinking. You hire another electrician or labourer because you've got the work, but somehow you're dipping into overdraft more, not less. That's a sign you're not pricing your jobs high enough to cover your growing overheads.

2. You're always waiting on payments. Cash flow is a nightmare. Customers take 30, 45, sometimes 60 days to pay, and in the meantime, you're paying your team, your suppliers, and your bills out of your own pocket. This is margin death — you're financing your customers' cash flow with your own.

3. You can't take a week off without panic. The moment you step away, things fall apart. Not because your team isn't capable, but because you're operating so close to the margin that there's no buffer for anything to go wrong. One delayed invoice, one supplier payment, one emergency, and you're in trouble.

4. You've got "so much work" but you feel poorer. This is the clearest sign. More jobs should mean more money — but if they don't, your prices are wrong. Or your costs aren't where you think they are.

5. You can't tell how much you actually made last month. You know turnover (revenue), but profit? That's a mystery until your accountant does your books three months later. If you don't know your margins on individual jobs, you're flying blind.

The Margin Formula That Changes Everything

Here's the most important formula you'll learn this year. Write it down. Tattoo it on your arm if you need to:

Net Margin % = ((Sales Price − Cost Price) / Sales Price) × 100

This tells you what percentage of every pound you keep as profit. Not revenue — actual profit that stays in your business.

Let's use a real electrician as an example:

Job: Kitchen rewire

Sales price: £2,000
Material costs: £400
Labour (15 hours at £45/hour): £675
Subcontractor: £200
Total cost: £1,275

Net Margin % = ((£2,000 − £1,275) / £2,000) × 100 = 36.25%

That's a healthy margin. But now add in your overheads: a £3,500 monthly overhead allocation (rent, insurance, software, vehicle costs, admin time) divided across 20 jobs a month = £175 per job.

Net Margin % = ((£2,000 − (£1,275 + £175)) / £2,000) × 100 = 30.5%

Still reasonable. But what if you didn't account for the overhead? You'd think you made £725 profit. You didn't — you made £550. That missing £175 disappears into rent, insurance, and the hundred other things that keep your business running.

The Real Example: Why 10% Margin Means Bankruptcy

A tradesperson doing £80,000 a year in revenue — that sounds like a viable income. Let's say 70% of that (£56,000) goes to direct costs: materials, labour, fuel, subcontractors. That leaves £24,000.

Your margin is: ((£80,000 − £56,000) / £80,000) × 100 = 30% margin.

Except — and this is the critical bit — your overheads for the year are £18,000. Rent, insurance, vehicle costs, tools, software, phones. That's pretty lean for a solo trader.

Real profit: £24,000 − £18,000 = £6,000 a year, or £500 a month.

That's not a business. That's a way to guarantee you'll stay broke.

Now imagine the exact same scenario, but your direct costs are actually £73,000 (you underestimated material waste, labour hours, or subcontractor costs). Your margin drops to 8.75%. After overheads, you've made a loss.

This is what happens to Gary's fencing business, and thousands of other tradespeople across the UK. They're busy, they're generating revenue, but their margins are so thin that the margin of error is zero.

The Psychology of Being Trapped

Here's the psychological trap: when you're in it, you can't see it. You think:

"Well, at least I've got work. At least people are calling. I'll get ahead once things quiet down." Except things don't quiet down — you get busier. And busier doesn't fix low margins. It just makes them hurt faster.

You think: "I need to grow. If I can just get to £100,000 revenue, I'll make it." But if your margins on that £100,000 are the same as your margins on £50,000, all you've done is accelerate your journey to overdraft.

You think: "My accountant says I'm profitable." Your accountant is looking at historical numbers, often months late, and they're usually looking at gross margin (revenue minus direct costs), not net margin (revenue minus all costs, including overheads). There's a world of difference.

How to Know If You're Actually Profitable

The answer is simple, but it requires being honest:

Calculate your net margin on every single job. Not weekly, not monthly — on every job. You need to know, the moment a customer pays (or the moment you invoice them), whether that job was profitable.

If you're doing £80,000 a year in revenue, and your overheads are £18,000 a year, you need a minimum of 22.5% net margin on every job just to break even after overheads.

£18,000 / £80,000 = 22.5% minimum margin required

Anything below that is making you poorer, even if it looks profitable on the surface.

Gary's fencing business needed a 6% margin just to cover overheads (£3,000 monthly overheads ÷ £50,000 monthly revenue). But his actual jobs were running at 2-4% margin. He was losing money on purpose, and the busier he got, the faster he lost it.

What This Means for Your Business

You might be reading this and feeling uncomfortable. That's good. Discomfort is the first step to change.

If you're busy but not profitable, you have three options:

Option 1: Raise your prices. This is the simplest option, and it terrifies most small business owners. You don't need to raise prices by 50%. You need to raise them by just enough to hit a healthy margin. A 5-10% price rise, done confidently, loses fewer customers than you think — and the ones you do lose are usually the ones who were destroying your margins anyway.

Option 2: Cut your costs. Look at every direct cost (materials, labour, subcontractors) and every overhead (rent, insurance, vehicles). Where can you be more efficient? Where are you paying for things you don't need?

Option 3: Stop doing low-margin work. This is the hardest option psychologically, but it's often the most profitable. We'll come back to this in our next post.

The uncomfortable truth is this: being busy is not a badge of honour. It's a trap. The real question isn't "how much revenue am I generating?" It's "how much of that revenue gets to stay in my business?"

Start calculating your margins. Start today. You might not like what you find, but I guarantee you that whatever you discover will be worth knowing.

Your action step: Pick your last five jobs. Calculate the net margin on each one using the formula ((Sales Price − Cost Price) / Sales Price) × 100. Be honest about costs — include materials, labour, any subcontractors, and a fair allocation of your overheads. Write the numbers down. You might surprise yourself.
