Are you really making money?
Profit vs revenue what your numbers are actually telling you

I'm going to be honest with you. A big part of why I started Little Black Books was because I kept meeting talented, hardworking entrepreneurs who had without meaning to created what I kindly call a bookkeeping crime scene. Not through laziness. Through busyness. Through the fact that when you're running a business, there are a hundred things competing for your attention, and the books always seem like they can wait until tomorrow.

But here's the pattern I see again and again: they come to me frustrated, exhausted, and confused. Their business is busy. Invoices are going out. The revenue number at the top of the P&L looks solid. And yet they're struggling to pay themselves properly, cashflow feels unpredictable, and there's a constant low-level anxiety that things aren't quite right.

When we sit down and actually look at the numbers together, the problem almost always comes back to the same thing: they've been watching revenue, when they should have been watching profit.

This isn't a failure of intelligence. It's a failure of financial literacy and it's incredibly common. Revenue is the number that feels exciting. It's the number you celebrate when a new client signs up or a big job comes in. Profit is quieter, harder to see, and far more important. My goal is always to get you genuinely excited about your profit number because once you understand it, it becomes one of the most powerful levers you have.

In this article, I'm going to walk you through exactly what profit and revenue mean, why they're so often confused, and most importantly what you can do to make sure your business is genuinely financially healthy, not just visibly active.

Let's start with clear definitions, because these terms get used loosely even by people who should know better.

The critical thing to understand is that revenue is not yours to keep. The moment a client pays you $10,000, that money doesn't belong to you in any meaningful sense it belongs to your suppliers, your staff, your landlord, the IRD, and a dozen other obligations. What's left after all of those obligations are met is profit. That is your money.

A business with $500,000 in annual revenue sounds impressive. But if that business has $490,000 in costs, it has $10,000 in profit a 2% net profit margin. That's not a healthy business; that's a business working incredibly hard for almost nothing.

When accountants and bookkeepers talk about profit, we're not always talking about the same thing. There are three distinct profit measures, each revealing something different about your business's financial health. Understanding all three is important.

Gross profit is what remains after you subtract the direct costs of delivering your product or service known as Cost of Goods Sold (COGS) or Cost of Sales. For a product business, this is the cost of the materials and manufacturing. For a service business, it typically includes the direct labour involved in delivering the service.

Gross profit margin tells you how efficiently you're delivering your core product or service. A falling gross margin is often the first sign that something is wrong prices are too low, costs are creeping up, or the mix of work has shifted toward less profitable jobs.

Operating profit also called EBIT (Earnings Before Interest and Tax) takes gross profit and subtracts your operating expenses: rent, utilities, insurance, marketing, software subscriptions, non-direct wages, and all the other costs of running the business day-to-day.

Net profit is the bottom line operating profit minus interest on any debt and income tax. This is your true take-home figure: the financial reward for everything you've invested in running your business. When people say a business is "profitable," net profit is almost always what they mean.

Let me illustrate this with a scenario I've seen many times. A tradesperson let's call her Emma runs a small painting business. In her first three years, Emma grew her revenue steadily: $180,000, then $260,000, then $340,000. Each year felt like progress. She hired a couple of staff, bought a new van, and took on bigger jobs.

But at the end of Year 3, Emma was barely paying herself. She owed money to suppliers. She was stressed about making payroll. How could a business doing $340,000 in revenue be in this position?

When we looked at her numbers properly, the picture became clear:

Emma was technically running a loss but the revenue number had masked it entirely. The business looked busy, active, and growing. What it actually was, was barely breaking even while Emma worked herself into the ground.

The fix wasn't dramatic. We identified that her materials costs had crept up without her pricing adjusting to match, and that one type of job she was taking regularly was significantly less profitable than the others. Two pricing adjustments and a decision to stop taking low-margin jobs put her business back on track within six months.

But none of that was possible until she could actually see the problem clearly. That's what understanding profit not just revenue makes possible. And that's exactly the kind of conversation we have with every client at LBBS: not just what the numbers are, but what they mean, and what to do about them.

Profit margin benchmarks vary significantly by industry, business model, and stage of growth. There are no universal answers but there are useful reference points.

These are reference points, not rules. What matters most is the trend in your margins over time. A gross margin that is slowly declining quarter by quarter is a serious warning sign it usually means costs are rising faster than prices, or that the mix of work is shifting toward lower-margin activity.

This is perhaps the most important distinction in all of business finance, and the one that catches the most business owners completely off guard.

It is entirely possible for a business to be profitable on paper and still run out of cash. This is not a theoretical scenario it is one of the most common reasons otherwise solid businesses fail.

Here's why: profit is an accounting concept. On an accrual basis (which is how Xero works by default), income is recorded when it is invoiced not when it is paid. Expenses are recorded when they are incurred not when the money leaves your account. Profit is therefore a measure of economic activity, not of actual cash movement.

Cashflow, by contrast, is exactly what it sounds like: the movement of actual money into and out of your bank account. You can invoice a client $50,000 in March. That $50,000 shows up in your profit figure for March. But if the client doesn't pay until May, you have no cash from that invoice in March or April even though you're "profitable."

Meanwhile, your costs keep coming. Staff need paying every fortnight. Suppliers expect payment within 30 days. GST is due. Rent doesn't pause while you wait for a slow-paying client.

The practical takeaway: you need to monitor both. A healthy business has strong profit margins and healthy, predictable cashflow. One without the other creates risk. Profit without cashflow means you might be building a technically successful business that can't pay its bills. Cashflow without profit means you might be surviving short-term while quietly burning through reserves.

In my experience working with small NZ businesses, thin margins rarely announce themselves loudly. They creep up slowly, masked by growing revenue and the general busyness of a trading business. Here are the warning signs I watch for:

1. You're busier than ever but not paying yourself more. If revenue is growing but your take-home pay isn't, costs are growing faster than income and margins are being eroded.
2. You feel relief when a client pays, rather than just noting it. This is a cashflow symptom, but it often points to an underlying margin problem there's no buffer because there's no real profit being generated.
3. Your prices haven't changed in over a year. Wages, materials, software, insurance, and fuel all increase annually. If your prices don't, your margins are shrinking automatically.
4. You don't know which of your services or clients is most profitable. If you're treating all work as equally good, you're almost certainly doing some work at very thin or even negative margins without knowing it.
5. Your accountant surprises you with a tax bill at year end. If your profit is higher than you expected, it means the business was more profitable than you realised which also means you weren't managing it intentionally.
6. You're discounting frequently to win work. Every discount comes directly off your margin. If your standard rate is already thin, a 10% discount could eliminate all your profit on that job.
7. You're spending more time doing admin than you used to. This one's more subtle, but growing administrative burden that isn't charged to clients is a hidden cost that quietly erodes profitability.

Here's the important news: profit margins are not fixed. They are the result of decisions about pricing, costs, the mix of work you take on, and how efficiently you deliver it. Those decisions can be changed. Here are the most effective levers I help clients work with.

This is almost always the highest-impact change available to small business owners and the one they are most reluctant to make. I see this constantly, especially with women in business who worry that raising prices will damage relationships or cause clients to walk. The fear is understandable. The reality, in most cases, is that a 10–15% price increase results in very little client attrition but a significant improvement in margins.

If you raise your price by 10% and lose 5% of clients as a result, you're working less and making more. That's a rational trade. But you can only make that assessment confidently if you know your numbers well enough to model it which is exactly what we help clients do as part of our advisory work at LBBS.

Not all revenue is equally valuable. In most businesses, there are clients or service types that generate healthy margins, and others that generate very thin ones. Identifying and deliberately reducing the low-margin work even if it means lower revenue almost always improves the financial health of the business.

Supplier costs, material costs, and subcontractor rates all creep up over time. If you're not reviewing your cost of sales at least quarterly, you're likely absorbing cost increases that should be reflected in your pricing. Set a calendar reminder it's one of the most financially valuable things you can do.

This is particularly common in service businesses. The quoted price doesn't account for all the scope creep, admin, client communication, and rework that's actually required. Track your time honestly for one month and compare it against what you billed. Most business owners are shocked by the gap.

Your break-even point is the amount of revenue you need to generate to cover all your fixed costs before you make a single dollar of profit. Knowing this number changes how you think about pricing, capacity, and growth decisions. It should be a number you know off the top of your head.

Everything I've described in this article is only possible if you have clean, accurate, up-to-date financial records. I know that's not a given for every small business it's actually one of the most common starting points I see. Business owners who have been doing the bare minimum on their books, or who've had a period of ignoring them completely, and have reached a point where the late-night Xero sweats are a regular occurrence.

I've built LBBS around a clear three-stage pathway that takes you from where you are right now wherever that is to a place of genuine financial clarity and confidence. It starts with getting your books clean, and it grows from there.

Here is what "knowing your numbers" actually looks like in practice and what LBBS delivers at each stage:

1. Your Xero is reconciled and up to date within two weeks, at most. This is Stage 1: our bookkeeping packages take this completely off your plate. Decisions made on stale data are guesses; decisions made on clean real-time data are strategy.
2. You receive a monthly Profit & Loss report you actually understand not just numbers in a spreadsheet, but commentary that tells you what's changed, what to watch, and what it means. Every LBBS bookkeeping client gets this as standard.
3. You know your gross and net profit margins for the business overall, and broken down by service or product line. This is where the Foundations program comes in: three months of structured work to build a custom financial dashboard that puts these numbers front and centre.
4. You have a rolling cashflow forecast 3–6 months forward, so you can see funding gaps before they become crises. Cashflow forecasting is at the heart of our Growth Advisory program, and it's one of the most transformative things we do with clients.
5. You have Sarah in your corner when a big decision comes up a pricing change, a hire, an investment. Not a once-a-year accountant, but someone who knows your business intimately and can give you a clear-eyed financial perspective on the spot. That's what being an LBBS advisory client actually feels like.

If you don't have all of these things in place right now, that's not a criticism it's an extremely common starting point. The question is simply: what's it costing you to not have them? In my experience, the answer is always more than people expect.
