Revenue is the number most business owners watch most closely. It makes sense — revenue is tangible, it shows up in the bank, and growth in revenue feels like progress.

But revenue alone is a misleading picture. A business can grow its revenue every month and still run out of cash. It can be profitable on paper and still struggle to pay salaries on time. It can look busy while the margins are quietly being eaten away.

These four numbers give you a fuller picture. Together, they tell you whether the business is not just generating revenue — but doing it sustainably.

The good news: once you have proper monthly accounts, reviewing all four takes about fifteen minutes.

Number 1: Gross Profit Margin

What it answers: Is the core of what we do financially viable?

How to calculate:

`(Revenue − Cost of Sales) ÷ Revenue × 100`

In simple terms: from every cedi you earn, how much is left after paying the direct costs of doing the work? If a client pays you GHS 10,000 and it costs you GHS 6,000 in materials, direct staff, and subcontractors to deliver — your gross profit is GHS 4,000 and your gross margin is 40%.

Why it matters: Your gross margin is what covers your overheads — rent, admin staff, utilities — and produces your profit. If it’s falling, it means either your costs of delivery are rising faster than your prices, or you’re doing work that doesn’t pay enough.

A real example: A business has GHS 80,000 in revenue and GHS 48,000 in direct costs. Gross margin = 40%. The following month, revenue is still GHS 80,000, but direct costs have risen to GHS 56,000. Gross margin has dropped to 30%. Profit is down by GHS 8,000 — and if nobody checked the margin, the business owner might think everything is fine because revenue didn’t change.

Number 2: Operating Cash Flow

What it answers: Is the business actually generating cash — or just profit on paper?

Profit and cash are not the same thing. Your P&L might show a GHS 50,000 profit for the month. But if your clients haven’t paid you, you might have GHS 5,000 in the bank.

Operating cash flow tracks the real money: what actually came in, what actually went out, and whether the business produced or consumed cash in the period.

In practical terms: Look at your bank balance at the start of the month, at the end, and strip out any financing activities (loan drawdowns, owner injections, capital expenditure). What’s left is a reasonable proxy for operating cash flow for a small business.

Why it matters: A business that consistently shows profit but negative operating cash flow is building up receivables it hasn’t collected — or it’s growing faster than its cash cycle can support. Both are fixable, but only if you can see them.

Number 3: Debtor Days

What it answers: How long does it take us to actually collect after we raise an invoice?

How to calculate:

`(Outstanding Invoices ÷ Monthly Revenue) × 30`

If your clients owe you GHS 90,000 at month-end and your monthly revenue is GHS 60,000:

(90,000 ÷ 60,000) × 30 = 45 days

Why it matters: If your payment terms say 30 days but your actual collection period is 75 days, your clients are effectively using your business as a free source of credit. Every extra day an invoice sits unpaid is a day that cash is sitting with someone else instead of in your account.

Extended debtor days are one of the most common causes of cash flow problems in Ghana SMEs — particularly those that deal with corporate or government clients who have their own (slower) payment cycles.

What to watch: If debtor days are consistently above your stated payment terms, you have a collections problem. If specific clients are consistently late, that’s information — the relationship might need to be renegotiated, or you might need to decide whether it’s commercially worth maintaining.

Number 4: Operating Expense Ratio

What it answers: How much of our revenue is being consumed by overhead costs?

How to calculate:

`Operating Expenses ÷ Revenue × 100`

Operating expenses are the costs of running the business that aren’t directly tied to delivering your service — rent, utilities, admin staff, office costs, subscriptions, insurance.

If your operating expenses in a month are GHS 18,000 and your revenue is GHS 80,000, your operating expense ratio is 22.5%.

Why it matters: As businesses grow, overheads tend to grow in steps — you hire a new person, take a bigger office, buy new equipment. If revenue isn’t keeping pace, the ratio rises, and profit suffers even when the top-line looks healthy.

What to watch: Set a target ratio for your business model and budget. Any month where the ratio jumps significantly — without a corresponding increase in revenue — deserves an explanation.

Reading All Four Together

The Prerequisite: Reliable Monthly Accounts

These four numbers are only as good as the data they’re calculated from. KPIs based on incomplete or inconsistent records give misleading signals.

The starting point is always a reliable set of monthly management accounts — a P&L, a balance sheet, and a cash flow summary, produced within five to seven working days of month-end. Everything else follows from there.
