The Cash Book (Junior Cert Business Studies): Revision Notes
The Cash Book
What is an analysed cash book?
An analysed cash book (ACB) is a financial record that tracks all money coming into (receipts) and going out of (payments) a business over a specific time period. It serves as the first step in the accounting process.
An analysed cash book helps businesses monitor their financial activities by recording every transaction that affects their bank account. Think of it as a detailed diary of a company's money movements - every euro received and every euro spent gets recorded with specific details about what the transaction was for.
The cash book can be maintained either manually in a physical record book or electronically using accounting software. Modern businesses typically use electronic systems as they handle larger volumes of transactions more efficiently.
Why businesses use analysed cash books
Businesses prepare analysed cash books for several important reasons:
- Track financial position - Shows exactly how much money the business has at any given time
- Monitor cash flow - Reveals patterns of money coming in and going out
- Analyse spending - Identifies where the business spends most of its money
- Evaluate income sources - Shows which activities generate the most revenue
- Make informed decisions - Provides data to guide future business choices
- Meet legal requirements - Helps businesses maintain proper financial records
Real-world application: A Dublin restaurant might discover through their cash book analysis that food purchases are their biggest expense, while weekend dinner sales generate the most income. This information helps them plan better purchasing strategies and focus marketing efforts.
Structure of cash books - debits and credits
The analysed cash book uses a two-sided format that separates different types of transactions:
- Debit side (Dr) - Records all money received (money coming IN)
- Credit side (Cr) - Records all money paid out (money going OUT)
Common debit entries (money in):
- Cash sales revenue
- Government grants received
- Loan proceeds
- VAT refunds from Revenue
- Tax refunds
- Payments from customers who owe money
- Investment from shareholders
Common credit entries (money out):
- Cash purchases of goods
- Loan repayments
- Payments to suppliers
- Staff wages and salaries
- Operating expenses (electricity, rent, etc.)
- Tax payments
- Dividend payments to shareholders
Memory aid: Remember that DR = money Received, CR = Cash going out. This simple rule will help you correctly classify all transactions in your cash book.
Preparing a business cash book
Business cash books follow the same basic structure as personal cash books, but include some important differences:
- Electronic transactions - Most business payments are made through online banking rather than cash
- Larger amounts - Business transactions typically involve higher values
- VAT considerations - Sales and purchases must account for Value Added Tax
VAT considerations
Value Added Tax (VAT) is a tax added to most business sales and purchases in Ireland, currently set at 23% for most goods and services.
When businesses sell goods or services, they must add VAT to the selling price. When they make purchases, they pay VAT that can often be reclaimed. This creates important considerations for cash book entries.
Worked Example: VAT on Sales
Mulligan's Bakery sells wedding cakes worth €2,000 plus 23% VAT.
Step 1: Identify the base amount Base sale amount = €2,000
Step 2: Calculate VAT amount
VAT amount = €2,000 × 23% = €460
Step 3: Calculate total received Total received = €2,000 + €460 = €2,460
Worked Example: VAT on Purchases
The same bakery buys ingredients for €800 plus 23% VAT.
Step 1: Identify the base amount Base purchase amount = €800
Step 2: Calculate VAT amount VAT amount = €800 × 23% = €184
Step 3: Calculate total paid
Total paid = €800 + €184 = €984
Opening and closing balances
The cash book begins each period with an opening balance, which represents the amount of money in the business bank account at the start of the period.
- Opening balance - The closing balance from the previous month becomes the opening balance for the new month
- Positive opening balance - Recorded on the debit side (business has money in the bank)
- Negative opening balance - Recorded on the credit side (business has an overdraft)
For instance, if Kerry Electronics had €1,200 in their bank account at the end of March, this €1,200 becomes their opening balance for April and gets recorded on the debit side.
Handling overdrafts
When a business has spent more money than it has in the bank, it creates an overdraft situation. The opening balance for an overdraft gets recorded on the credit side of the cash book, showing that the business owes money to the bank.
How to balance a cash book
Balancing a cash book involves a systematic four-step process:
Worked Example: The 4-Step Balancing Process
Step 1: Add up all amounts in each analysis column to get subtotals
Step 2: Calculate the total of both the debit side and credit side bank columns. On the side with fewer transactions, skip a line after the last entry and write the larger total from step 2
Step 3: Find the difference between the two bank totals - this difference represents the closing balance
Step 4: Complete the balancing entries:
- Write "Balance c/d" (carried down) above the larger total on the side that needs balancing
- Write "Balance b/d" (brought down) on the opposite side for the next period
This process ensures that both sides of the cash book equal each other and clearly shows the final bank balance. Always double-check your arithmetic at each step.
Analysing cash book information
Once completed, the analysed cash book provides valuable business intelligence:
- Current financial position - The closing balance shows exactly how much money is available
- Primary income sources - Analysis columns reveal which activities generate the most revenue
- Major expenses - Shows where the business spends the most money
- Financial trends - Comparing balances shows whether the financial situation is improving or deteriorating
Real-world example analysis
Worked Example: Cash Book Analysis
Consider O'Brien Construction's November cash book showing:
- Opening balance: €5,000
- Closing balance: €12,500
- Largest income source: Project payments (€15,000)
- Largest expense: Equipment purchases (€6,500)
Analysis: This tells O'Brien Construction that their financial position improved by €7,500 during November, with project work being their most profitable activity and equipment being their biggest expense category.
Cash books for different organisations
While the basic structure remains the same, different types of organisations have specific considerations:
Not-for-profit organisations (charities, clubs, community groups) typically include additional analysis columns for:
- Donations received
- Fundraising event income
- Sponsorship payments
- Lottery funding
- Grant payments from foundations
These organisations focus less on profit and more on tracking how effectively they use donated funds to achieve their mission.
Key Points to Remember:
- The analysed cash book is the foundation of business accounting - it records all money in and money out
- Debit side captures receipts (money in), while credit side tracks payments (money out)
- The four-step balancing process ensures accuracy and shows the true bank balance
- Analysis of completed cash books provides crucial insights for business decision-making
