Key Concepts
There are two main types of businesses:
| Trading Business | Service Business | |
|---|---|---|
| What it does | Buys goods from suppliers and sells goods to customers | Provides services to customers |
| Revenue earned | Sales revenue | Service fee revenue |
| Has Inventory? | Yes | No |
| Has Cost of sales? | Yes | No |
| Examples | Bookstore, supermarket, hardware shop | Tuition agency, consultancy firm, photography studio |
Note: Inventory is the goods a business holds, ready to sell. Cost of sales is the cost of the goods the business sold during the period — what it paid to acquire those goods from suppliers.
The key distinguishing feature is the main source of revenue. If the business:
- earns mainly from selling physical goods → trading business (it will have inventory and cost of sales);
- earns mainly from providing a service → service business.
What if a business does both? Classify by what it mainly does. For example, Ravi runs a grocery shop but also rents out a small corner of the shop to a fruit vendor. His primary income is still from selling groceries — so his business is a trading business, even though he also earns some rental income.
Ask: "Does this business sell physical goods to customers?"
- Yes → Trading business (has inventory, has cost of sales)
- No → Service business (no inventory, no cost of sales)
Watch out: A delivery business does not sell goods — it provides a delivery service. The goods belong to someone else.
Classify each business as trading or service, and justify your answer.
Firefly Traders
Type: Trading business.
Reason: It buys electronic goods from suppliers and sells them to customers. It holds inventory and earns sales revenue from the sale of goods.
Blue Kite Photography
Type: Service business.
Reason: It provides photography services to clients and earns service fee revenue. It does not sell physical goods to customers and does not hold inventory.
Classifying a delivery business as a trading business. A delivery business provides a service — it does not own or sell the goods it delivers. It earns service fee revenue, not sales revenue.
Forgetting to give a reason when asked. The question usually asks you to "name the type and explain your reason." The reason must refer to whether the business sells physical goods (inventory) or provides a service.
Confusing "selling food" with "providing a food delivery service."
- A hawker stall that sells food to customers is a trading business.
- A food delivery platform that only transports food for others is a service business.
