WAEC SSCE Building Construction
Study notes for Book Keeping — part of the WAEC SSCE Building Construction syllabus. 3 learning objectives with explanations and exam tips.
Book keeping is the process of recording all business transactions in books of accounts. Think of it as keeping a detailed diary of every money movement in a construction company. When a building contractor buys cement, pays workers, or receives payment from clients, these transactions must be written down systematically. This creates a clear financial record that shows where money comes from and where it goes.
For example, a Lagos construction firm that builds residential houses must record every naira spent on materials, labour, and equipment. These records help the business owner know their profit or loss, manage cash flow properly, and prepare accurate financial statements for tax purposes.
Good book keeping prevents fraud, supports decision-making, and satisfies government tax requirements. The records must be accurate, complete, and organized in chronological order using standard accounting methods.
Book keeping simply means keeping records of all money that comes in and goes out of a business. Think of it as your business's diary for money matters. When a small business owner like Alhaji selling fabrics in Balogun Market receives cash from customers or spends money buying new stock, all these transactions must be written down properly.
Good book keeping helps small business owners know exactly how much profit they made, what money they owe suppliers, and how much customers owe them. Without proper records, a business owner cannot make smart decisions about whether the business is actually making money or losing it.
For example, if Mama Tayo runs a successful pepper soup restaurant in Lagos, she needs to record daily sales, costs of ingredients, and staff payments. At the end of each month, these records show her real profit and help her plan better.
Books of original entries are the first documents where a business records all its daily transactions before moving them to other accounting records. Think of them as the initial "catch point" for every money movement in a business. These books capture transactions right when they happen, making them the foundation of accurate record-keeping.
The main books of original entries include the cash book, sales journal, purchases journal, and general journal. For example, when a Lagos trader buys goods from a supplier on credit, this transaction first enters the purchases journal. When customers pay cash for items, it goes into the cash book first. These records are then transferred to the ledger accounts later.
The beauty of these books is their organization—they group similar transactions together, making accounting easier and reducing errors significantly.
