How to Track Income and Expenses as a Data Reseller in Nigeria (2026)
How to Track Income and Expenses as a Data Reseller in Nigeria (2026)
The short answer: To know your real profit as a data reseller, you need three numbers: total sales (all money customers pay you), total expenses (wallet funding, transport, airtime, data, bank fees, marketing), and net profit (sales minus expenses). Record every transaction immediately, review weekly, and calculate profit monthly. A free offline app like Dextrac makes this simple.
You sold ₦100,000 worth of data last month.
You funded your wallet four times. You paid for transport to meet a customer. Your data subscription expired twice. You bought airtime to call customers.
So how much did you actually make?
If you can't answer that question with a specific number, you're not alone. Most data resellers in Nigeria focus entirely on sales — they check their wallet balance, see money coming in, and assume they're profitable. But sales and profit are two different things.
This guide will show you a simple system to track your income and expenses, so you always know exactly how much your data reselling business is actually making.
If you haven't started your reselling business yet, the step-by-step guide on how to start a data reselling business in Nigeria walks you through everything. But if you're already selling and want to know your real numbers, keep reading. And if you want a general guide to tracking personal spending, see our free expense tracker app guide for Nigeria.

The Problem: Sales vs. Profit
Let me show you why this matters with a real example.
What most resellers see:
| Item | Amount |
|---|---|
| Total data sold | ₦100,000 |
| Wallet funding | ₦80,000 |
| "Profit" | ₦20,000 |
That looks simple. But it's wrong.
What actually happened:
| Item | Amount |
|---|---|
| Total sales | ₦100,000 |
| Cost of data (wallet spending) | ₦80,000 |
| Transport to meet customers | ₦3,000 |
| Personal data/internet | ₦5,000 |
| Airtime for customer calls | ₦2,000 |
| Bank transfer fees | ₦1,500 |
| Actual profit | ₦8,500 |
The difference is ₦11,500. That's money you thought you had but you don't.
This is the trap. When you mix business money with personal money, you never really know if you're making a profit or slowly losing money. For a general guide on separating personal and business tracking, see our expense tracker app guide.
Why Don't Most Resellers Track Their Money?
There are three common reasons:
1. "It's too complicated."
You didn't start a data business to do accounting. You wanted to sell data and make money. Tracking feels like extra work.
2. "I know I'm making profit."
You see money entering your account. You assume you're fine. But without tracking, you can't tell the difference between ₦5,000 profit and ₦500 profit.
3. "I'll start tracking when I'm bigger."
This is the most dangerous one. The habits you build when you're small determine how big you can grow. If you don't track ₦50,000 in sales, you won't track ₦500,000.
The truth: The resellers earning ₦100,000+ monthly are not necessarily selling more than you. They just know their numbers. They know which bundles make the most profit, which customers are worth keeping, and where their money is leaking. If you want to see what's possible at different levels, check out how much you can make reselling data in Nigeria.
The Three Numbers You Need to Know
Every data reselling business has three important numbers:
1. Total Sales (Revenue)
This is the total amount customers pay you. If you sell ₦600 data to 10 people, your total sales are ₦6,000.
Important: This is not your money. It's money passing through your hands.
2. Total Expenses
This is everything you spend to run the business. It includes:
- Cost of buying data from WiseSub (your wallet funding)
- Transport to meet customers or buy airtime
- Your personal data subscription (used for the business)
- Airtime for calling customers
- Bank transfer fees
- Any data you give out for free as promotion
- Money spent on customer acquisition (e.g., printing flyers, boosting posts)
3. Net Profit (What You Actually Keep)
Net Profit = Total Sales − Total Expenses
This is the only number that matters. This is your real income.
How Do You Track Your Income (Money In)?
Tracking income is simple. Every time a customer pays you, record it.
What to record:
| Date | Customer | Amount | Service | Payment Method |
|---|---|---|---|---|
| 20/09/2026 | Mary | ₦600 | MTN 1GB | Bank transfer |
| 20/09/2026 | John | ₦1,200 | MTN 2.5GB | Cash |
| 21/09/2026 | Amina | ₦580 | Airtel 1GB | Bank transfer |
Where to record it:
- A notebook (if you prefer paper)
- A simple Google Sheet or Excel file
- A tracking app on your phone (we'll cover this later)
Tip: Record every sale, no matter how small. A ₦100 airtime sale counts. If you ignore small sales, your records will be inaccurate and you'll make bad decisions. For a general guide to daily spending habits, see our free expense tracker app guide.
How Do You Track Your Expenses (Money Out)?
This is where most resellers fail. They track income but ignore expenses.
Common expenses for Nigerian data resellers:
| Expense Category | Examples |
|---|---|
| Cost of goods | Money you fund into your WiseSub wallet |
| Transport | Bus fare to meet customers |
| Data/internet | Your personal data used for the business |
| Airtime | Calls to customers, follow-up calls |
| Bank charges | Transfer fees from your bank |
| Marketing | Flyers, WhatsApp bulk messages (if paid), social media ads |
| Miscellaneous | Any other business-related spending |
How to track expenses:
The moment you spend money for the business, write it down.
| Date | Description | Amount | Category |
|---|---|---|---|
| 20/09/2026 | Wallet funding | ₦20,000 | Cost of goods |
| 20/09/2026 | Transport to Ikeja | ₦1,500 | Transport |
| 21/09/2026 | Airtime recharge | ₦1,000 | Airtime |
| 22/09/2026 | Data subscription | ₦2,000 | Internet |
Tip: Keep business money separate from personal money. Use a dedicated bank account or mobile money wallet for your business. This makes tracking much easier and prevents you from accidentally spending business money on personal things. For a general guide on personal expense tracking, see our free expense tracker app guide for Nigeria.
How Do You Calculate Your Actual Profit?
At the end of each week or month, do this simple calculation:
Step 1: Add up all your sales.
Step 2: Add up all your expenses.
Step 3: Subtract expenses from sales.
Net Profit = Total Sales − Total Expenses
Example:
| Amount | |
|---|---|
| Total sales for September | ₦100,000 |
| Cost of data (wallet funding) | ₦80,000 |
| Transport | ₦3,000 |
| Data/internet | ₦5,000 |
| Airtime | ₦2,000 |
| Bank charges | ₦1,500 |
| Total expenses | ₦91,500 |
| Net Profit | ₦8,500 |
That's your real profit. Not ₦20,000. Not ₦100,000. ₦8,500.
Now you know exactly where you stand.
A Simple Weekly Tracking Routine
You don't need to do complex accounting. Just follow this simple routine:
| Day | Action |
|---|---|
| Every sale | Record it immediately (customer, amount, service) |
| Every expense | Record it immediately (what, how much, category) |
| Every Friday | Add up the week's sales and expenses |
| Every month end | Calculate your net profit and review your numbers |
This takes 5–10 minutes per day. That's it.
Tip: Set a reminder on your phone to record your daily numbers. Consistency is more important than perfection.
What Common Mistakes Should You Avoid?
1. Mixing personal and business money.
If you use the same account for everything, you'll never know your real profit. Open a separate account or wallet for your data business. If you need help tracking personal spending separately, see our expense tracker app guide.
2. Not recording small expenses.
That ₦200 transport fare adds up. That ₦500 airtime recharge adds up. Record everything.
3. Forgetting to account for your own time and data.
Your personal data subscription is a business expense. Your time has value. If you're spending 4 hours a day on this business and making ₦5,000 profit, you're earning ₦1,250 per hour. Is that worth it? Now you can decide.
4. Only tracking when business is good.
Track during slow months too. That's when you'll see where money is leaking.
5. Using "wallet balance" as profit.
Your WiseSub wallet balance is not profit. It's money you've already spent to buy data. Profit is what's left after all expenses.
Tools You Can Use to Track Your Money
You don't need expensive accounting software. Here are simple options:
1. Notebook and Pen
The simplest option. Write down every sale and expense. It works, but it's hard to calculate totals quickly.
2. Google Sheets or Excel
Create a simple spreadsheet with columns for Date, Description, Income, and Expense. This lets you calculate totals automatically.
3. Mobile Tracking Apps
There are apps designed specifically for tracking daily income and expenses. For example, Dextrac is a free app that lets you:
- Record income and expenses as they happen
- See a summary of your monthly income, expenses, and balance
- Filter transactions by date range
- View reports by category
- Export your data to Excel
- Works completely offline
Dextrac is built for people who want a simple way to track their money without learning accounting. You can download it from the Google Play Store. For a full guide on using Dextrac and other tracking methods, see our free expense tracker app guide for Nigeria.
Why this matters: When you use a tracking app, you can see your profit in real time. You don't have to wait until month end to know if you're making money.
Frequently Asked Questions
Do I really need to track my income and expenses?
Yes. Without tracking, you're guessing. Guessing leads to bad decisions. Tracking tells you exactly how much profit you're making and where your money is going.
How often should I track?
Record every transaction as it happens. Review your totals weekly. Calculate your profit monthly.
What if I don't have time to track?
Tracking takes 5–10 minutes per day. If you don't have 10 minutes, you don't have a business — you have a hobby.
Is it okay to use my personal bank account for the business?
It's better to use a separate account. But if you must use your personal account, at least keep a separate record of all business transactions. Our expense tracker app guide shows you how to track personal and business spending separately.
What's the most important number to track?
Your net profit. That's the only number that tells you if your business is actually working.
Can I use Dextrac for my data reselling business?
Yes. Dextrac is designed for daily income and expense tracking, which is exactly what a data reseller needs. You can download it free from the Google Play Store. For a full guide on using Dextrac, see our free expense tracker app guide.
What if I discover I'm not making profit?
First, don't panic. Look at your expenses. Are there costs you can reduce? Look at your pricing. Are you selling too cheap? Small adjustments can turn a loss into a profit. You can also check our guide on cheap MTN data in Nigeria to make sure you're buying at the best rates.
How do I know if I'm pricing correctly?
Track your profit per transaction. If you're selling MTN 1GB for ₦600 but it costs you ₦580 after all expenses, you're not making money. Review our guide on how to buy cheap data in Nigeria to make sure you're getting the best wholesale prices.
The Bottom Line
Selling data is easy. Knowing whether you're actually making money is harder.
But it doesn't have to be complicated. You just need three numbers: total sales, total expenses, and net profit. Track them consistently, and you'll always know where you stand.
Here's your simple action plan:
| Day | Action |
|---|---|
| Today | Start recording every sale and expense |
| This week | Calculate your weekly totals |
| This month | Calculate your net profit |
| Next month | Use last month's numbers to make better decisions |
