Module 4 of 5
Revenue, cost, and profit. Simple financial tracking. Pricing your product or service.
Blessing runs a catering business in Port Harcourt, Nigeria. She caters weddings, corporate events, and birthday parties. In a good month, she collects 800,000 Naira in payments. She works six days a week. She is always busy. She has never taken a salary because 'it all goes back into the business.'
When her sister asks how the business is doing, Blessing says 'fine, always busy.' When her accountant friend asks to see her profit margin, Blessing does not know what that means in practice. She knows she is busy. She does not know if she is profitable.
This is the most common financial blindspot in African small business: confusing revenue with profit, and confusing being busy with being financially successful. This module installs the financial clarity that Blessing needs — and that every entrepreneur deserves.
Every business financial conversation begins with three numbers. If you know these three, you can make every major business decision with clarity. If you do not, you are navigating without a map.
Revenue is the total money your business receives from customers before any costs are deducted. It is the top line. For Blessing: 800,000 Naira collected in a good month is her monthly revenue.
Cost is everything your business spends to generate that revenue. Costs fall into two categories:
Direct costs (also called Cost of Goods Sold or COGS): the costs that vary directly with each order — food ingredients, packaging, delivery fuel, event staff wages. If Blessing does not cater an event, these costs do not occur.
Fixed costs (also called overhead): the costs that occur regardless of how much business you do — rent, utilities, your own salary (yes, you should pay yourself), insurance, loan repayments, annual licenses.
Profit is what remains after all costs are deducted from revenue. Gross profit = Revenue minus Direct Costs. Net profit = Revenue minus All Costs (direct + fixed). Net profit is the true measure of whether your business is financially viable.
Blessing's financial reality check: if she earns 800,000 Naira in revenue but spends 650,000 on ingredients, staff, fuel, kitchen rental, and equipment maintenance — her gross profit is 150,000 Naira. If her fixed costs (loan repayment, her own salary, utilities) are 120,000 Naira, her net profit is 30,000 Naira on 800,000 in revenue. That is a 3.75% net profit margin. She is working six days a week for a 3.75% margin. That knowledge changes what she does next.
Research across African SMEs consistently finds that fewer than 30% of small business owners can accurately state their monthly profit — as distinct from their revenue. Businesses that track profit monthly are 2.5 times more likely to survive past 5 years than those that do not.

You do not need accounting software to start tracking your finances. You need a system you will actually use — and the simpler it is, the more likely you are to use it.
The Minimum Viable Financial System for a Small Business:
An income log: every time money comes in, record it. Date, customer, amount, what it was for. This can be in a notebook or Google Sheets — both work. The requirement is that you do it every time, the same day.
An expense log: every time money goes out, record it. Date, what for, amount, category (ingredients / staff / transport / fixed costs). Keep every receipt. Photograph receipts with your phone and store in a Google Drive folder called 'Receipts [Month Year].'
A monthly summary: at the end of each month, total your income and your expenses by category. Calculate gross profit and net profit. Write these numbers down. This is your financial report.
The most common objection: 'I don't have time.' The counter: recording a transaction takes 30 seconds. Missing a transaction means making business decisions without accurate data. The time cost of the tracking system is minutes per day. The cost of not tracking is potentially years of working hard at a business that is not generating the returns it should.
Using AI to set up your tracking sheet: go to ChatGPT and type: 'Create a simple Google Sheets income and expense tracking template for a [type of business] in [country]. Include columns for income and expense categories relevant to this type of business, and a monthly summary formula.' Copy the structure and set it up in your Google Drive.
Underpricing is the most common financial mistake made by African small business owners — particularly women entrepreneurs, who research consistently shows are more likely to undervalue their time and expertise. Pricing should be based on costs plus a deliberate profit margin — not on what you think customers will pay, what competitors charge, or what feels comfortable to ask for.
The cost-plus pricing formula:
Calculate your direct cost per unit: add up all the costs that go specifically into producing one unit of your product or delivering one hour of your service. For Blessing catering one wedding: food cost + packaging + fuel + day-of staff wages divided by number of guests.
Add your overhead allocation: divide your total monthly fixed costs by the number of units or hours you produce in a month. This gives you the overhead cost per unit.
Add the two together: direct cost + overhead allocation = total cost per unit.
Apply your target profit margin: if you want a 30% profit margin, divide total cost by 0.70. The result is your minimum price. If you want a 40% margin, divide by 0.60.
Example: Blessing's direct cost to cater 100 guests is 150,000 Naira (food, packaging, fuel, day-of staff). Her monthly overhead allocated to this event is 20,000 Naira. Total cost: 170,000 Naira. At a 35% margin, minimum price: 170,000 / 0.65 = 261,538 Naira. If she is currently charging 200,000 Naira for this event, she is losing money on it — while being busy.
Use AI to check your pricing: type into ChatGPT: 'I run a [type of business] in [city/country]. My direct cost to produce/deliver [product/service] is [amount]. My monthly fixed costs are [amount] and I produce approximately [number] units per month. What price should I charge to achieve a 30% net profit margin? Show me the calculation.'
Cash flow is one of the most misunderstood concepts in small business finance — and misunderstanding it has bankrupted profitable businesses. Cash flow is not profit. A business can be profitable on paper and still run out of cash — if the timing of when money comes in does not match the timing of when money goes out.
Example: a printing business takes a large order worth 200,000 Naira. The paper and ink cost 80,000 Naira, payable immediately to the supplier. The customer pays 30 days after delivery. If the business has no cash reserve, it cannot buy the materials to fulfill the order — even though the order is profitable.
Cash flow management principles for small businesses:
Require deposits: for any order above a threshold, require a 50% deposit before beginning work. This is standard practice globally and protects your cash position while also filtering out unserious customers.
Invoice immediately: send the invoice the same day you deliver. Every day of delay in invoicing is a day of delay in payment.
Know your cash cycle: how many days, on average, between when you spend money on an order and when you receive payment? This gap — the cash conversion cycle — tells you how much cash you need in reserve.
Build a cash reserve: the goal is 1-3 months of fixed costs sitting in a separate account, untouched except for genuine emergencies. This reserve is what allows you to take on large orders, survive a slow month, and negotiate with suppliers from a position of strength rather than desperation.
Pezesha is a Kenyan fintech company that provides working capital loans to small businesses embedded within the digital platforms those businesses already use. Rather than requiring businesses to go to a bank with paper documents and wait weeks for approval, Pezesha's algorithm assesses creditworthiness using data from the business's existing digital activity — M-Pesa transaction history, inventory management platform data, and order records.
The key insight: most Kenyan small businesses are considered 'unbankable' by traditional lenders because they lack the formal financial records banks require. But their M-Pesa history, their consistent order patterns, and their payment records are actually robust evidence of creditworthiness — just in a format banks do not know how to read.
For a business like Blessing's catering company, Pezesha-style financing means: when a large wedding order comes in and she needs 100,000 Naira for ingredients immediately but payment is not due for 45 days, she can access short-term working capital without going to a moneylender at exploitative rates.
The implication for financial tracking: the digital records you create by using mobile money, tracking orders in Google Sheets, and invoicing through Wave Accounting are not just operational tools. They are building a financial history that can eventually give you access to capital. Every transaction recorded is an asset in a future credit application.
Calculate your actual profit margin for last month.
Collect every income and expense record you have from last month — bank statements, M-Pesa history, receipts, notebook entries. Total all income. Total all expenses, separating direct costs from fixed costs. Calculate: gross profit (income minus direct costs), and net profit (income minus all costs). Divide net profit by income to get your net profit margin percentage. If this number surprises you — either because it is lower than expected or because you genuinely could not calculate it — that surprise is information.
Price one of your products or services using the cost-plus method.
Choose one product or service. Calculate its direct cost per unit (add up everything that goes into it). Allocate overhead (total monthly fixed costs divided by total units you produce per month). Add the two. Apply a 35% margin (divide total cost by 0.65). Compare this to what you currently charge. If your current price is below this number, you now know the minimum you need to charge to be profitable.
