Welcome to Business Cycles: Mapping the Auditor’s Journey
Hello future CPAs! Welcome to one of the most practical parts of your Principles of Auditing studies. If you have ever wondered how an auditor actually "does" the work, this is it. Instead of looking at every single transaction (which would take forever!), we group transactions into Business Cycles. Think of these as the natural "flows" of a business—like how a shop buys stock, sells it, and then pays its staff.
In this chapter, we will learn how to apply specific audit procedures to these cycles. Don't worry if it seems like a lot of steps at first; once you see the logic behind the "flow" of money and goods, it will start to make perfect sense!
Quick Review: What are we trying to prove?
Before we dive in, remember our "Assertions." We are checking if things Exist, if they are Complete (nothing is missing), if the Values are right, and if they happened in the right Period (Cut-off).
1. The Sales and Collection Cycle
This cycle is all about Revenue and Accounts Receivable (A/R). It’s usually the area with the highest risk because companies might want to "inflate" their sales to look better.
Key Risk: Overstatement
The biggest worry here is Occurrence—did the sale actually happen, or is it a "ghost" sale?
Common Audit Procedures:
1. External Confirmation: We send letters directly to the company's customers asking, "Do you really owe this amount?"
2. Vouching: We pick a sale in the accounting records and "vouch" it back to the Shipping Documents and Sales Invoices. This proves the sale occurred.
3. Tracing: We pick a Shipping Document and "trace" it forward to the Sales Ledger. This proves Completeness (that every shipment was recorded as a sale).
4. Cut-off Testing: We look at sales made a few days before and after the year-end (e.g., Dec 31) to make sure they are recorded in the correct year.
Analogy: Imagine you are checking a friend's diary. Vouching is like seeing "I bought a burger" and asking for the receipt. Tracing is like finding a receipt in their pocket and checking if it’s written in the diary.
Key Takeaway:
For Sales, Occurrence is the main concern (checking if they lied about making a sale). For Accounts Receivable, Existence and Valuation (can the customer actually pay?) are key.
2. The Purchases and Payment Cycle
This cycle covers buying goods and paying Accounts Payable (A/P). Unlike sales, the risk here is usually Understatement—companies might try to hide their debts to look "healthier."
Key Risk: Completeness
The auditor’s main job is to find "unrecorded liabilities."
Common Audit Procedures:
1. Search for Unrecorded Liabilities: We look at bank payments made after the year-end. If we see a big payment in January for goods received in December, we check if it was recorded as a debt on Dec 31.
2. Reconciling Supplier Statements: We compare what the company says they owe to the actual statement sent by the supplier.
3. Vouching: Checking recorded purchases against Goods Received Notes (GRN) and Purchase Invoices.
Did you know? Auditors often care more about a missing $10,000 debt than a $10,000 purchase that was recorded twice. Why? Because missing debts make the company look better than it really is!
Key Takeaway:
Focus on Completeness. Always ask: "Is there a bill they haven't told us about?"
3. The Inventory and Production Cycle
Inventory is often the most difficult area because it is physical. You can't just look at a computer screen; you usually have to go see it!
Key Risks: Existence and Valuation
Does the stock exist? And is it worth what they say it is (or is it broken/old)?
Common Audit Procedures:
1. Attendance at Physical Stock Take: The auditor observes the client counting the stock. We perform "test counts" (counting items ourselves and comparing to their sheets).
2. NRV Testing (Valuation): We check if the inventory is recorded at the lower of Cost or Net Realizable Value (NRV).
\( NRV = \text{Estimated Selling Price} - \text{Costs to Sell} \)
3. Observation: Looking for dusty or damaged boxes during the count. This suggests the stock is obsolete and its value should be written down.
Common Mistake: Students often think the auditor performs the count. No! The client counts the stock; the auditor observes to make sure they are doing it correctly.
Key Takeaway:
If it’s physical, go see it (Existence). If it’s old or broken, lower the price (Valuation).
4. The Payroll and Personnel Cycle
Payroll is usually a high volume of small transactions. The main risks are "Ghost Employees" (fake people on the payroll) and Accuracy of calculations.
Common Audit Procedures:
1. Analytical Procedures: Comparing this year's total salary expense to last year's, adjusted for new hires or pay rises. If it’s roughly the same, it’s a good sign.
2. Recalculation: Manually calculating the tax (MPF in Hong Kong) and net pay for a sample of employees.
3. Existence Check: Picking a name from the payroll and asking to see their ID card or watching them pick up their pay cheque (if paid in person).
Memory Aid: Think of the 3 "P"s of Payroll: People (Do they exist?), Pay (Is the math right?), and Period (Is it for this month?).
Key Takeaway:
Payroll is often tested using Substantive Analytical Procedures because it is usually very predictable.
5. The Capital Acquisition and Repayment Cycle (Cash & Finance)
This involves how the company gets its money (loans or issuing shares) and its Bank Balances.
Common Audit Procedures:
1. Bank Confirmation: This is crucial. We get a letter directly from the bank listing all balances, loans, and even "contingent liabilities" (guarantees).
2. Bank Reconciliation: We check the "bridge" between the bank statement and the company's books. We look for "outstanding cheques" and "deposits in transit."
3. Inspection of Loan Agreements: Reading the contracts to make sure the interest rates and repayment dates are recorded correctly.
Quick Review Box: The Bank Confirmation
- It is sent by the Auditor.
- It is replied to directly to the Auditor (not the client).
- It provides high-quality evidence for Existence and Rights & Obligations.
Summary Checklist for Students
When you are faced with a question about audit procedures for any cycle, ask yourself these three things:
1. What is the asset or liability? (e.g., Inventory, A/P)
2. What is the biggest risk? (e.g., Does it exist? Is it complete?)
3. What document proves it? (e.g., Invoice, Shipping Note, Bank Statement)
Don't worry if this seems tricky at first! Auditing is like being a detective. You are just looking for the best "clues" (evidence) to prove that the story told by the financial statements is true. Keep practicing with past papers, and these procedures will become second nature!
