# Complete Guide to Tracking Business Expenses in Nigeria
"I make good sales, but where does all the money go?"
If you've asked yourself this question, the answer is simple: **untracked expenses are eating your profit**.
A 2025 study of 1,000 Nigerian SMEs found that businesses that track expenses properly have **40% higher profit margins** than those that don't. Why? Because you can't control what you don't measure.
## Why Most Nigerian Businesses Fail at Expense Tracking
### The Common Excuses:
- "It's just small money, no need to write it down"
- "I'll remember what I spent"
- "Too busy serving customers to write expenses"
- "I don't know how to categorize expenses"
### The Costly Reality:
₦500 daily untracked expenses = ₦15,000/month = ₦180,000/year
That's enough to buy a generator, pay 3 months rent, or hire staff.
## The 5 Categories of Business Expenses
### 1. Cost of Goods Sold (COGS)
**What it is:** Money spent to acquire/produce the products you sell.
**Examples:**
- Buying goods from suppliers
- Raw materials for production
- Delivery fees to get stock
- Import duties/customs fees
**How to track:**
```
Date: July 23, 2026
Supplier: Alhaji Musa
Items: 50 bags of rice @ ₦32,000 each
Transport: ₦5,000
Total COGS: ₦1,605,000
```
**Pro Tip:** COGS should be 40-60% of your sales price for healthy margins.
### 2. Operating Expenses (OPEX)
**What it is:** Day-to-day costs to run your business.
**Fixed Operating Expenses (same every month):**
- Shop rent: ₦60,000/month
- Staff salaries: ₦90,000/month
- Internet/data: ₦5,000/month
- Subscriptions (BosApp, etc.): ₦3,500/month
**Variable Operating Expenses (changes daily/weekly):**
- Electricity/generator fuel: ₦30,000/month
- Transportation: ₦20,000/month
- Phone credit: ₦8,000/month
**How to track:**
```
DAILY OPERATING EXPENSES
Date: July 23, 2026
Transport to market: ₦500
Generator fuel: ₦1,200
Lunch for staff: ₦1,500
Phone credit: ₦200
Pure water (12 bags): ₦600
Total Daily OPEX: ₦4,000
```
### 3. Marketing & Sales Expenses
**What it is:** Money spent to attract customers and make sales.
**Examples:**
- Facebook/Instagram ads: ₦10,000/month
- Flyers/posters: ₦5,000
- Influencer promotion: ₦15,000
- WhatsApp Business subscription: ₦0 (free)
- Promotional airtime giveaways: ₦20,000
**ROI Tracking:**
```
Facebook Ads Campaign - July 2026
Amount Spent: ₦10,000
New Customers: 15
Sales Generated: ₦45,000
ROI: 350% (₦45K revenue from ₦10K spent)
```
**Golden Rule:** Track which marketing brings customers. If Facebook ads bring 10 customers but flyers bring 0, stop printing flyers!
### 4. Administrative Expenses
**What it is:** Business paperwork and compliance costs.
**Examples:**
- Business registration (CAC): ₦10,000 (one-time)
- Annual returns filing: ₦5,000/year
- Accountant fees: ₦15,000/year
- Bank charges: ₦500/month
- Receipt/invoice printing: ₦2,000/month
### 5. One-Time/Capital Expenses
**What it is:** Major purchases for long-term use.
**Examples:**
- Generator: ₦85,000
- Freezer: ₦120,000
- Display shelves: ₦45,000
- POS machine: ₦15,000
- Business furniture: ₦80,000

## Common Expense Tracking Mistakes
### Mistake #1: Not Separating Personal & Business Expenses
**Wrong:** Taking ₦5,000 from cash box to buy personal airtime
**Right:** Pay yourself a fixed salary, use that for personal needs
### Mistake #2: Forgetting Small Expenses
₦100 here, ₦200 there adds up to ₦50,000/month
### Mistake #3: Not Tracking Credit Purchases
You bought on credit today, you'll pay cash next week. Track it NOW.
### Mistake #4: No Receipt = No Record
If there's no receipt, write it down immediately or you'll forget.
### Mistake #5: Tracking Monthly Instead of Daily
Monthly tracking is too late. Track DAILY, review WEEKLY.
## The Expense-to-Revenue Ratio
**Healthy Business Ratios:**
```
Total Expenses ÷ Total Revenue = Expense Ratio
Target: 60-75%
(This means 25-40% profit margin)
Example:
₦400,000 expenses ÷ ₦600,000 revenue = 67% (✅ Healthy)
₦550,000 expenses ÷ ₦600,000 revenue = 92% (❌ Dangerous!)
```
If your expense ratio is above 80%, you're in trouble. Either:
1. Reduce expenses
2. Increase prices
3. Sell more volume
