You made more sales this month. Things are busy. Orders are coming in, customers are paying and, on paper, the business looks like it is doing well.

Then you check the account and think: “Wait. Where did all that money go?”

It’s frustrating, especially when you know the business is making sales. But the problem may not be how much money is coming in. It may be how much is quietly slipping back out.

A supplier increases their prices and nobody notices. An invoice sits unpaid for three weeks. Stock has been sitting on the shelf since February. The team is still paying for software nobody remembers signing up for. Then there are those ₦5,000, ₦10,000 and ₦20,000 charges that seem too small to worry about.

Until there are hundreds of them.

These are operational leaks. They rarely arrive with a siren. They show up as unnecessary expenses, delayed payments, wasted time and avoidable mistakes that gradually eat into your margins.

Making more sales is only part of the job. You also need to know how much of that revenue the business actually keeps.

Here are 10 places worth checking.

1. Buying Things Whenever You Need Them

Need more packaging? Buy it. Ran out of printing paper? Buy it. Someone suddenly remembered they need something by 3 p.m.? Buy it.

It feels convenient, especially when the business is moving quickly. But a little “just this once” purchasing habit has a way of becoming the unofficial procurement strategy. And when nobody is tracking what gets bought, from whom or at what price, convenience can come with an expensive markup.

The plug: Track recurring purchases, compare supplier prices periodically and set reorder levels for essential supplies. Where possible, consolidate orders instead of making multiple last-minute purchases.

You don’t need a procurement department. You just need to stop buying like nobody is keeping score.

2. Cash Sitting in Slow-Moving Stock

Stock is useful when it is moving. When it isn’t, it is basically your money taking a nap on a shelf.

Too much inventory ties up cash you could use elsewhere. Too little can mean missed sales. The trick is knowing what actually sells and what has quietly become part of the furniture.

The plug: Review your sales history to identify fast-moving and slow-moving products. Discount, bundle or otherwise clear excess stock where it makes commercial sense, and adjust future orders to reflect actual demand. Buy based on what customers demonstrate they want, not just what you hope they will buy.

3. Customers Owing You Money

A sale doesn't automatically mean cash in the bank.

If a customer takes 30, 60 or 90 days to pay, you're effectively financing that sale while waiting for your own money. Meanwhile, staff, suppliers and bills have not agreed to wait politely. You can be profitable on paper and still struggle to cover everyday expenses because too much of your cash is sitting in unpaid invoices.

The plug: Issue invoices promptly, agree on payment terms before work begins and send reminders before invoices become overdue. For larger jobs, consider deposits or milestone payments to reduce the amount of money you have to front.

Your customers don't need to be chased aggressively. They just need to know that “I'll pay soon” is not an actual payment date.

4. Subscriptions Nobody Is Using

Remember that software you subscribed to for one project six months ago? Yes. It remembers you too. Every month. Individual charges can look harmless, but ₦20,000 here, ₦15,000 there and another $49 somewhere else can become a surprisingly expensive museum of tools nobody opens.

The bigger problem is that these payments often continue long after the original need has disappeared.

The plug: Keep a central list of subscriptions, their renewal dates, costs and owners. Review it quarterly and cancel tools that no longer serve a clear purpose. Where several tools do similar jobs, check whether one can replace the others.

If nobody can explain why you're paying for it, it's time to investigate.

5. Paying People to Do Robot Work

If someone spends two hours every Monday copying numbers between spreadsheets, compiling the same report or sending identical follow-up emails, you may be paying human wages for work a tool could handle.

That time could be spent serving customers, solving problems or improving the business instead. And no, this isn't about replacing your team with AI. It's about getting repetitive work out of their way.

The plug: Identify tasks that happen frequently and follow predictable steps. Start with simple automation using your existing spreadsheets, CRM, email platform or workflow tools. Calculate how much time the task takes each month and compare that with the cost of automating it. Not every task needs software, but the repetitive ones are worth examining.

Let people do the thinking. Let software handle the copying and pasting.

6. Paying Twice for the Same Mistake

A wrong delivery. An invoice with the wrong amount. A customer request that gets forgotten. A product sent to the wrong address. The original mistake costs you. Fixing it costs you again. Then there's the customer trust you have to rebuild. And telling the team to “be more careful” isn't much of a solution if the process practically invites the same mistake to happen again.

The plug: Identify where the error occurred and change the process that allowed it. Introduce checklists for repetitive tasks, verify critical details before dispatch and clarify who is responsible at each handover.

Don't just pay to correct the mistake. Make it harder for the same mistake to happen again.

7. Every Decision Has to Pass Through You

You started the business, so of course you want to know what's happening.

But if every refund, supplier payment, customer issue and ₦50,000 expense needs to wait for you, you've quietly become the business's biggest approval queue.

And queues are not exactly famous for helping businesses move faster.

Beyond the delays, constant approvals pull you away from work that actually requires your attention.

The plug: Establish approval limits and clear rules. Decide what your team can handle independently, what requires a second opinion and what genuinely needs your sign-off. Use spending limits and simple reporting to maintain oversight without approving every little thing.

You should be able to see what's happening in your business without personally touching every decision.

8. Prices That Haven't Caught Up With Your Costs

Revenue looks healthy because you're selling more. Meanwhile, your margins are getting thinner. Supplier prices went up. Delivery costs went up. Payment fees changed. Staff costs increased. Your own prices? Still sitting there like it's two years ago.

You could be doing more work, serving more customers and generating more revenue without earning a proportionate increase in profit.

The plug: Calculate what it currently costs to deliver each product or service, including direct materials, labour, delivery, payment fees and an appropriate share of overheads. Review your prices against those costs and the margin you need to sustain the business.

Your old price may have made sense two years ago. That doesn't mean it still does today.

9. The Little Fees Adding Up

Nobody panics over a small transaction fee. ₦500? Fine. ₦1,000? It happens.

But multiply those charges across hundreds or thousands of transactions and suddenly they're taking a meaningful bite out of your margins. Payment processing fees, bank charges and foreign transaction fees can be easy to overlook when you're focused on the money coming in.

The plug: Review your bank statements and payment provider charges to understand what you're paying and why. Compare available payment options, check whether your transaction volume qualifies you for better rates and avoid unnecessary foreign currency charges where possible.

Small fees are easy to ignore individually. Your bank statement sees the full picture.

10. Not Knowing Where the Money Is Going

This is the leak that makes all the others harder to spot.

If you only review your numbers when someone asks for a report, you could spend months paying for inefficiencies before noticing the damage. You don't need to become a finance expert. You need enough visibility to spot unusual spending, identify cash flow problems and make informed decisions.

The plug: Set aside 30 minutes each week to review three things: cash coming in and going out, outstanding customer invoices, and recurring or unusual expenses. Compare spending with previous weeks or months so you can investigate changes before they become bigger problems.

You don't need to stare at a spreadsheet until your eyes cross. Just make sure you know what the money is doing.

Try a 30-Minute Leak Check

You don't have to fix all 10 problems this week. Start with the last 30 days of business activity and look for patterns.

1. Where did we keep spending money?

Review supplies, subscriptions, delivery costs, transaction fees and other recurring expenses. Look for charges that have increased, purchases you could have consolidated or payments that no longer make sense.

2. Where did we keep spending time?

Look for repetitive manual work, unnecessary approvals, recurring errors and tasks that take longer than they should. These may be costing you through wasted labour, delays or missed opportunities.

3. Where did cash get stuck?

Check unpaid invoices, slow-moving stock and money spent on supplies or services long before you needed them. Identify what you can recover, collect or avoid tying up next time.

Then choose one leak you can fix immediately and assign someone to handle it. Record what it was costing you and check again next month to see whether the change made a difference.

Because growing your revenue is important. But if money keeps leaking out through the back door, you'll keep wondering why the business feels busier without feeling much richer.
