Revenue vs Profit: The Difference That Is Silently Killing Nigerian Small Businesses

I want to tell you about a conversation I have had more times than I can count.

Someone DMs me or pulls me aside at an event. They are excited. They just had their best month ever, five hundred thousand naira in sales, maybe eight hundred, maybe more. They are glowing and then, almost as an afterthought, they say: “But I don’t know where my money went.”

That sentence. “I don’t know where my money went.”

It is the most common sentence in Nigerian small business and it is not because the person is careless or irresponsible. It is because nobody ever sat them down and explained the difference between two numbers that look similar but mean completely different things.

Revenue and profit.

Once you understand the difference and really understand it, not just the textbook definition, a lot of the confusion about your business finances will start to clear.

So let me walk you through it the way I wish someone had walked me through it.

Let Me Start With a Story You Will Recognise

Chidinma sells fashion items on Instagram, she had her best month yet, about ₦800,000 in sales. She screenshot every credit alert, she posted a gratitude reel, she told her mum things were finally moving.

By the 28th of the same month, she had only ₦35,000 in her account.

She did not get robbed, nothing dramatic happened, she just spent the money. Not recklessly as one will naturally think, she spent it on the business, Stock, Deliveries, Packaging, Data, Ads, a little for herself, all reasonable things.

But she had no idea what she actually kept from that ₦800,000 and that is where the problem lies.

You can make a lot of sales and still be broke. In fact, you can be growing your sales month on month and still be getting poorer if you do not know what is staying with you versus what is passing through.

That is the revenue-profit gap and it is quietly ruining businesses that look successful from the outside.

Here’s a number that should stop you cold:In 2024, 65% of informal Nigerian businesses reported revenue growth but only 47% saw an increase in profit. Nearly 8 in 10 said their cost of doing business went up. Revenue rising. Profit not following. That gap is not a coincidence, it is what happens when you do not track both numbers.

What These Two Words Actually Mean

I know you have probably heard both terms before but I want to be precise, because the confusion is real and it is costing people money.

Revenue is the total amount of money that comes into your business. Every sale, every client payment, every transfer. If orders totalling ₦800,000 cleared this month, your revenue is ₦800,000. That’s it, nothing is subtracted yet.

Profit is what you have left after subtracting everything it cost you to make those sales, Stock, Packaging, Delivery, Data, Ads, Bank charges, Generator fuel, Transport, Your own salary if you pay yourself one and everything else.

The formula is not complicated:

Revenue  −  Total Expenses  =  Profit

Simple, right? The issue is not the formula. The issue is that most people know their revenue number intimately, they feel every credit alert but their expenses are a blur.

They are paid one by one, often mixed with personal spending, and never added up until it’s too late to do anything about it.

Revenue is what looks good in your captions, profit is what you can actually use.

Here Is Where Your Money Is Actually Going

Let me show you what Chidinma’s ₦800,000 month probably looked like, in real numbers. This is not hypothetical, I built this from the kind of expense breakdowns I see from Lagos-based Instagram sellers constantly.

Where the money went	Amount (₦)
Stock and inventory purchases	350,000
Packaging (bags, tissue, tags, stickers)	18,000
Delivery and logistics fees	22,000
Data — phone and Wi-Fi router	8,500
Instagram ads and promotions	30,000
Bank charges and transfer fees	3,200
Generator fuel (home office)	15,000
Transport (market runs, drop-offs)	12,000
Personal withdrawal (‘salary’ this month)	80,000
Damaged or unsold stock written off	25,000
Total Expenses	563,700
Profit (Revenue ₦800k − Expenses ₦563.7k)	₦236,300

So her real profit is ₦236,300. Not bad at all, honestly. Certainly not ₦35,000.

So why was her account almost empty by the 28th?

Two things happened. First, she restocked immediately after the big sales came in, which meant most of that profit went straight back into new inventory before she could see it as money.

Second, she and her business share one account, so when she spent ₦80,000 on herself across the month, there was no system distinguishing “business expense” from “I felt like buying something.”

This is not a character flaw, It is a system problem and I say that because I want you to fix the system, not beat yourself up.

The Expenses You Are Probably Not Counting

The big-ticket expenses you always remember are probably rent. stocks, staff salaries if you have them but what actually kills you are the quiet stuff.

Let me go through the ones I see people miss most often:

• Bank charges and transfer fees: Every USSD transaction, every account maintenance fee, every inward transfer charge. At ₦50–₦100 per transfer, a busy month adds up fast. I have seen people spending ₦5,000–₦8,000 monthly in bank fees they never once wrote down.
• Paystack fees. If you collect payments via Paystack, they charge 1.5% per transaction, capped at ₦2,000. On ₦800,000 in sales, that’s ₦12,000 leaving before the money even reaches your account. When did you last account for that?
• Generator fuel. NEPA is not going to be reliable anytime soon. If you run a home office or a small studio in Lagos, you are spending between ₦10,000 and ₦25,000 monthly on fuel. I almost never see this in anyone’s expense records.
• Your own time and transport. The Bolt to the market. The bus fare to drop off an order. The data you spend answering customer DMs at 11pm. Your time has a cost. Your transport has a cost. If you are not tracking it, you are subsidising the business with your own money and calling it a sacrifice.
• Damaged or unsold stock. If you are in fashion, food, or beauty, some percentage of what you buy will never sell, or will get damaged in delivery. Writing it off properly is the honest way to account for your real profit. Most people just absorb it and wonder why the numbers feel off.

According to research on African SME operations, hidden costs consistently represent 20–30% of monthly expenses in small African businesses. That means for every ₦100 you think you’re spending, another ₦20–₦30 is quietly leaving without being recorded.

And there is one more that sits above all of these:

Mixing personal and business money. When you have one account for everything, every personal expense becomes a business expense by default even if you never intended it that way. This one habit is one of the major reasons why people can’t tell what their actual profit is.

How to Calculate Your Real Profit (Do This Right Now)

I am not going to give you a complicated framework, I am going to give you five steps. Do them at the end of this month, actually do them.

1. Write down every naira that came into the business. Sales, payments, transfers, cash from customers. All of it. This is your revenue number.
2. Write down every naira that left. Stock. Packaging. Logistics. Data. Ads. Fuel. Bank charges. Everything you paid for to run the business this month. Do not leave anything out because it feels too small.
3. Add up what you took out for personal use. Every grocery purchase from the business account. Every personal Bolt ride charged to the business. Every random withdrawal. Put a real number on it and include it in your expenses.
4. Subtract total expenses from revenue. That number is your profit. If it is low, you now know why. If it is negative, the business is running on borrowed time and you also need to know that.
5. Compare to last month. Is profit going up as sales grow? Or is revenue climbing while profit stays flat? A gap between those two trends is your signal that costs are getting out of hand.

One thing worth knowing: Nigeria’s Tax Act 2025 taxes your profits, not your revenue. That means the government will ask what you kept after expenses. If you have no expense records, you cannot defend that number. Knowing your real profit is not just good business sense, it is also how you stay on the right side of FIRS.

The Habits That Actually Help

Knowing you should track your expenses and actually tracking them are two different things. So let me tell you what genuinely works, not what sounds good in theory.

Separate your accounts. I cannot stress this enough. Business income goes into one place. Personal spending comes from another. You do not need a fancy corporate account to start a second personal account works. The moment you separate them, your finances will start to make sense in a way they never have before.

Record expenses the moment they happen. Not at the end of the week. Not when you remember. The moment money leaves, write it down. Delayed recording is where accuracy goes to die. A week later you will not remember what that ₦3,200 transfer was for.

Do not skip the small amounts. I know ₦1,500 for packaging feels too small to bother writing down but do it anyway. Add up 15 of those across a month and you have ₦22,500 that your profit calculation knows nothing about.

Review weekly, not monthly. A monthly review tells you what went wrong. A weekly review gives you a chance to fix it. There is a big difference between catching a cost problem on the 10th of the month and finding out on the 30th.

If you want to go deeper on how real Nigerian business owners actually think about costs, this Zikoko piece is honest and practical. Business owners walk through their actual pricing logic, hidden costs included. Worth reading.

How Velvy Handles This For You

I will be direct: doing all of this manually is genuinely hard, not because the steps are complicated, but because you are also running a business.

You have orders to fulfil, customers to reply to, suppliers to chase. Sitting down to reconcile expenses at the end of the month often loses out to everything else that is more urgent.

This is what I like about Velvy for this exact problem. When a client pays an invoice, the revenue is recorded automatically. When you log an expense, which takes about 10 seconds, it sits against your revenue. At any point, you can open the dashboard and see your revenue, your expenses, and your actual profit, not an estimate but the real number.

There is also Zino, which is Velvy’s WhatsApp AI assistant. If you live in WhatsApp like most Nigerian business owners do, you can literally message Zino “Log expense of ₦12,000 on packaging today” and it is logged. No app to open, no form to fill in, It just goes into your records.

You can start free at velvy.app. The first five invoices are on them. But beyond invoicing, it is the expense tracking and the profit view that I think will change how you see your business.

The Thing I Want You to Walk Away With

Revenue is the exciting number. Everyone talks about it. “I made ₦500k this month.” “I crossed a million.”

Profit is the honest number. And it is the only one that tells you if your business is actually working.

I have seen businesses with ₦2 million in monthly revenue that were quietly collapsing and I have seen businesses with ₦400,000 in monthly revenue that were stable, growing, and paying their owners well.

The difference was not the sales number. It was the profit number and whether the owner knew it and made decisions based on it.

Start tracking yours this month even if it is messy. Even if you are playing catch-up on two months of unrecorded expenses. The clarity that comes from knowing your real profit will change how you price, how you spend, and what decisions you make.

You cannot grow a number you are not watching.
