Ask ten small business owners in Nigeria how much money their business made last month, and eight of them will look uncertain. They know money came in. They know money went out. But the exact picture? Blurry.

This is the cash flow problem, and it quietly kills more small businesses than bad products ever do.

What Is Cash Flow?

Cash flow is simply the movement of money in and out of your business. Money coming in (income) minus money going out (expenses) equals your net cash flow.

If more money comes in than goes out, your cash flow is positive. If more goes out than comes in even temporarily, your cash flow is negative, and you have a problem.

A business can be profitable on paper but still run out of cash. This is how businesses that seem to be doing well suddenly can't pay rent or buy new stock.

Why Tracking It Matters

You'll know whether you're actually making money, not just generating activity
You can spot problems early before they become crises
You'll make smarter decisions about spending, restocking, and pricing
It makes tax time easier if you're registered
It builds a foundation for getting credit or investor funding later

The Simple 3-Column Tracking System

You don't need accounting software to start. Open a notebook or a free Google Sheet and create three columns:

Column 1 — Date: When the money moved
Column 2 — In or Out: Whether it was income or an expense, and what it was for
Column 3 — Amount: How much

Record every transaction, every sale, every purchase, every expense, every refund. Every single one. This takes 5–10 minutes per day, or 30 minutes per week if you batch it.

Weekly vs Monthly Review

Weekly review (10 minutes every Sunday): Add up your income for the week and your expenses. Is the gap positive? Are there any unusual expenses you need to flag?

Monthly review (30 minutes on the last day of each month): Calculate total income, total expenses, and net cash flow for the month. Compare to last month. Spot trends.

Red Flags to Watch For

Your expenses consistently grow faster than your income
You regularly have 'nothing to show' despite busy sales periods
You're always borrowing money to restock or pay for operations
You can't tell your business money apart from your personal spending

One Rule Above All Others

Keep your business money and personal money in separate accounts. This is the single most important step for any small business. If they're mixed, you'll never truly know how your business is doing.

Open a separate account, even a basic bank account and run all business income and expenses through it exclusively.
