Introduction to Departmental Accounts and Incomplete Records

Welcome! In this chapter, we are going to look at two specific scenarios in accounting. First, how do businesses track the performance of different parts of their shop (Departmental Accounts)? Second, what happens when a business owner doesn't keep perfect books and we have to play detective to find the missing numbers (Incomplete Records)?

By the end of these notes, you will understand how to organize financial statements into columns for different departments and how to use accounting "clues" to build a full set of accounts from scratch. Don't worry if it seems like a lot—we will take it step-by-step!

Part 1: Departmental Accounts

Imagine a large store that sells both Clothing and Electronics. The owner wants to know which department is making a profit and which might be losing money. Instead of one big total, we split the Statement of Profit or Loss into columns.

1. The Columnar Format

The main difference between a standard Statement of Profit or Loss and a departmental one is the layout. You will have a column for each department (e.g., Dept A, Dept B) and a Total column.

Key rule: Gross Profit is calculated for each department individually by tracking their specific Revenue, Opening Inventory, Purchases, and Closing Inventory.

2. Allocation vs. Apportionment

This is where students often get confused, but the logic is simple:

  • Allocation: If an expense belongs only to one department (like the salary of a manager who only works in Clothing), we "allocate" the whole amount to that column.
  • Apportionment: If an expense is shared (like Rent for the whole building), we must "apportion" (split) it using a fair basis.

3. Common Bases for Apportionment

If the exam doesn't tell you exactly how to split a cost, look for these logical links:

  • Rent, Rates, Heating, Lighting: Usually split by Floor Area (square meters).
  • Depreciation of Machinery: Usually split by the Value of Machinery in each department.
  • Staff Canteen Costs or Insurance: Often split by the Number of Employees.
  • Advertising: Usually split based on Revenue (Sales).

Quick Review: Departmental accounts help management identify which areas of the business are performing well and which need improvement. Always remember to sum the individual department totals into the "Total" column!

Part 2: Incomplete Records

Sometimes, small business owners do not use a full double-entry system. They might only have a list of cash received, a bank statement, and some invoices. Our job is to use the Accounting Equation and other techniques to find the missing figures.

1. Finding Opening Capital (The "Net Assets" Approach)

If you don't know the starting capital, you can find it using the basic accounting equation:

\(\text{Assets} - \text{Liabilities} = \text{Capital}\)

To find the Opening Capital, simply list all the assets and liabilities the business had on the first day of the year.

2. Finding Purchases and Sales (Control Account Technique)

Often, the "Total Sales" or "Total Purchases" figure is missing. We use Control Accounts to find these. Think of these as a "money-in, money-out" puzzle.

To find Credit Sales: Prepare a Trade Receivables Control Account.

  • Debit side: Opening balance, Credit Sales (Missing figure!).
  • Credit side: Cash/Bank received from customers, Irrecoverable debts, Sales returns, Closing balance.

To find Credit Purchases: Prepare a Trade Payables Control Account.

  • Debit side: Cash/Bank paid to suppliers, Purchase returns, Closing balance.
  • Credit side: Opening balance, Credit Purchases (Missing figure!).

3. Calculating "Drawings"

In incomplete records, the owner often takes cash or goods for personal use without recording it. If you have the opening and closing bank balances and all other expenses, the "leftover" difference is often Drawings.

Part 3: Using Ratios to find Missing Values

This is a very common exam topic. If the Inventory or Purchases figure is missing, examiners will give you the Gross Profit Margin or Mark-up.

1. Margin vs. Mark-up

Margin is profit as a percentage of Revenue (Sales).

\(\text{Percentage Margin} = (\frac{\text{Gross Profit}}{\text{Revenue}}) \times 100\)

Mark-up is profit as a percentage of Cost of Sales.

\(\text{Percentage Mark-up} = (\frac{\text{Gross Profit}}{\text{Cost of Sales}}) \times 100\)

2. The "Magic" Formula for Missing Figures

If you know the Revenue and the Margin, you can find Gross Profit and then work backward to find Cost of Sales:

\(\text{Revenue} - \text{Gross Profit} = \text{Cost of Sales}\)

Once you have Cost of Sales, you can find missing Inventory or Purchases using:

\(\text{Cost of Sales} = \text{Opening Inventory} + \text{Purchases} - \text{Closing Inventory}\)

Common Mistakes to Avoid

  • Mixing up Margin and Mark-up: Always check if the percentage is based on Sales (Margin) or Cost (Mark-up).
  • Ignoring Cash Sales: Total Sales = Credit Sales (from Control Account) + Cash Sales (from Cash Book). Don't forget to add them together!
  • Apportionment Errors: Ensure that when you split a cost (like rent), the total of the departmental columns equals the original expense.
  • Drawings of Goods: If an owner takes inventory for themselves, this must be deducted from Purchases in the Statement of Profit or Loss.

Key Unit 1 Ratios (Quick Reference)

In this chapter, you may be asked to calculate or use these Unit 1 ratios to evaluate the business:

  • Current Ratio: \(\frac{\text{Current Assets}}{\text{Current Liabilities}}\) (Target is usually 2:1)
  • Liquid (Acid Test) Ratio: \(\frac{\text{Current Assets} - \text{Inventory}}{\text{Current Liabilities}}\) (Target is usually 1:1)
  • Rate of Inventory Turnover: \(\frac{\text{Cost of Sales}}{\text{Average Inventory}}\) (Measured in 'times')
  • Trade Receivables Collection Period: \((\frac{\text{Trade Receivables}}{\text{Credit Sales}}) \times 365\) (Measured in 'days')
  • Return on Capital Employed (ROCE): \((\frac{\text{Net Profit Before Interest}}{\text{Capital Employed}}) \times 100\)

Summary Checklist

✓ Departmental: Use columns, allocate direct costs, and apportion shared costs using a fair basis.
✓ Incomplete Records: Use the accounting equation for Capital, Control Accounts for Sales/Purchases, and a Cash Summary for Drawings.
✓ Mark-up/Margin: Use these ratios to "plug the gaps" in the Trading section of the Statement of Profit or Loss.
✓ IAS Terminology: Always use "Statement of Financial Position" instead of Balance Sheet and "Inventory" instead of Stock!
