You opened the shop early. Customers came. Money changed hands all day. By evening your hand has touched more cash than most people see in a week. And yet — by the end of the month, there's nothing left. No savings, no growth, sometimes not even enough to restock.

If this sounds familiar, the problem usually isn't how hard you're working. It's that you're tracking cash, not profit — and those are two very different things.

Cash in hand is not the same as profit

Cash flow is money moving in and out of your hands today. Profit is what's actually left over after every cost is paid — stock, transport, fees, the small "settling" payments, even the data you bought to confirm an order. Most of that money was never yours to keep; it was just passing through your hands on its way to someone else.

A business can look busy and still be losing money, quietly, every single day — because the owner is reading their cash, not their costs.

Three silent profit killers

• Untracked small expenses. Transport, "ageru," wrapper, recharge card — each one feels too small to write down. Added up over a month, they often equal a week's profit.
• Mixed money. When business and personal money sit in the same pocket or account, you can't see your real numbers — and you'll always spend more than the business can afford.
• Selling below true cost. If your price only covers what you paid the supplier — and not transport, fees, and waste — every sale quietly loses money, no matter how many you make.

How to know your real number

The fix isn't complicated, but it does require honesty: write down every cost — not just the big ones — and compare it against every sale. Do that for two weeks and you'll know, for the first time, whether your business is actually profitable or just busy.

Most small business owners price by feeling — copy what a competitor charges, round a number that "sounds right," or just see what customers will pay. The problem is that none of those methods tell you whether you're actually making money.

Correct pricing isn't a guess. It's a calculation, and it only needs five numbers.

The 5 numbers every price must cover

• Cost price — what you paid your supplier, per unit.
• Transport cost — getting the goods from supplier to you (or to the customer).
• Market or other fees — loading fees, packaging, platform charges, anything else attached to the sale.
• Quantity in the batch — costs like transport are often per-trip, not per-item, so they need to be spread across everything you bought.
• Your target profit margin — the percentage of the final price that should be profit, not just an amount added on top.

The formula

Add up your total cost per unit (cost + transport + fees, divided by quantity). Then divide that by (1 − your margin as a decimal). That gives you the selling price where your margin is exactly what you wanted — not roughly, exactly.

A quick walkthrough

Say you bought 10 hair wigs for ₦70,000 total, spent ₦4,000 on transport and ₦3,000 on market fees. Your total cost is ₦77,000 — ₦7,700 per unit. If you want a 30% margin, your selling price is ₦7,700 ÷ 0.70 = ₦11,000, giving you ₦3,300 profit per wig. Sell below that and you're trading time for nothing.

Ask any business owner whose shop has survived more than three years what they do differently, and almost all of them will mention some version of the same habit: they write things down, every day, without skipping.

Not fancy accounting. Not software, at first. Just three honest columns, kept daily: what I sold, what I spent, and who owes me.

Why "I'll remember" doesn't work

Memory is the most common bookkeeping method in small business — and the most expensive one. A ₦500 transport cost feels too small to note. A customer who promises to "pay next week" feels too informal to write down. But multiply small, unrecorded moments by 30 days, and most owners are stunned by what they discover once they finally start tracking.

The habit, broken down

• Every sale — even the ₦200 one. If it's not written down, you can't know your real total at month end.
• Every expense — transport, restock, fees, "settling." These are the leaks that quietly empty a profitable-looking business.
• Every debt — who owes you, how much, and since when. Untracked debt is money you've already earned but may never collect.

Make it stick

A notebook works. So does a phone notes app. What matters is doing it at the same time every day — closing time is usually easiest — so it never piles up into a task too big to face.

Once the habit is in place, the next step is simply making it faster and harder to skip — which is exactly what a proper tracking tool is for.
