1. Business Entity Concept

This concept states that a business is treated as a separate legal entity from its owner(s). This means the business has its own money and property, which is different from the owner's personal money.

Key point: Only business transactions are recorded in the business books, not the owner's personal expenses or income.

Example: Mwanaisha owns a shop in Dar es Salaam. She invests TSh 500,000 of her own money into the business. According to the business entity concept, this money is treated as capital (a liability of the business to the owner), not as the owner's personal money.

2. Money Measurement Concept

This concept requires that only transactions that can be expressed in monetary terms (money) should be recorded in the books of accounts.

Key point: If something cannot be measured in shillings, it is not recorded in accounting.

Example: Mwanaisha's shop has a loyal customer base and a good reputation. These are valuable, but they cannot be expressed in TSh, so they are not recorded in the accounting books.

3. Dual Aspect Concept

Every financial transaction affects at least two accounts. This is the foundation of the double entry system of bookkeeping.

Key point: For every debit entry, there must be a corresponding credit entry.

Example: Mwanaisha buys shop fittings for TSh 200,000 cash.

• Furniture and fittings account (asset) increases by TSh 200,000 — debit
• Cash account (asset) decreases by TSh 200,000 — credit

4. Going Concern Concept

This concept assumes that a business will continue to operate for the foreseeable future (at least beyond the next 12 months) and has no intention of shutting down.

Key point: Because of this assumption, assets are recorded at their purchase price (historical cost) rather than their current selling price.

Example: Juma Enterprises owns a delivery truck bought for TSh 15,000,000. Even if the truck's market value is now TSh 10,000,000, it is still recorded at TSh 15,000,000 because the business is expected to keep using it, not sell it.

5. Accounting Period Concept

While a business is expected to continue forever, we need to know how well it is performing at regular intervals. This concept divides the life of a business into equal time periods.

Key point: The life of a business is divided into accounting periods (usually 12 months) for reporting purposes.

Example: Most businesses in Tanzania prepare financial statements every year — for example, from 1st January to 31st December. At the end of each year, they prepare reports showing profit or loss.

6. Historical Cost Concept

Assets are recorded in the books at the price actually paid to acquire them (original purchase price), not their current market value.

Key point: Assets are recorded at cost price, not resale value.

Example: Fatuma bought a sewing machine for her tailoring business in Arusha for TSh 350,000 two years ago. Even if the machine can now be sold for TSh 250,000, it is still recorded at TSh 350,000 in her books.

7. Matching Concept

This principle requires that revenues and the expenses used to generate those revenues should be recorded in the same accounting period.

Key point: Match income with the costs that produced it.

Example: In June 2024, Rajabu sold goods for TSh 100,000 but the goods were purchased in May 2024 for TSh 60,000. The profit of TSh 40,000 is calculated in June (the month of sale), not May, because that is when the revenue was earned.

These accounting concepts are not used in isolation. They support each other:

• The Going Concern Concept allows the Historical Cost Concept to be applied — because the business will keep using assets, we record them at purchase price.
• The Accounting Period Concept allows the Matching Concept to work — we match revenues and expenses within each period to calculate profit or loss.

• Business Entity: Keep business and personal transactions separate.
• Money Measurement: Record only what can be measured in money.
• Dual Aspect: Every transaction affects two accounts.
• Going Concern: Assume the business will continue indefinitely.
• Accounting Period: Divide business life into equal reporting periods.
• Historical Cost: Record assets at purchase price.
• Matching: Record revenues and related expenses in the same period.

When you eventually work in a shop, hotel, or any business in Tanzania, you will need to understand these concepts to record transactions correctly. For example, if you work at a local market stall in Kariakoo and sell goods worth TSh 50,000, you must record both what you sold (revenue) and the cost of the goods you bought to sell (expense) in the same month to know if you made a profit or a loss. This matching principle helps small business owners know exactly how their business is performing.
