Audit of Revenue and Receivables: Sales, Revenue Recognition and Debtors

Updated 10 October 2026 · Fact-checked

Audit of revenue and receivables means gathering evidence that sales are real, recorded in the right period at the right amount, and that debtors are genuine and recoverable. You test assertions, vouch sales from order to cash, check cut-off, confirm balances with debtors, review ageing and judge the provision for doubtful debts.

Understand Audit of Revenue and Receivables

Revenue is the top line of the Statement of Profit and Loss. Receivables are the asset that most revenue creates. Both are high-risk areas, because management may want to show higher profit. Overstating sales or hiding bad debts is the easiest way to do it.

Under SA 240, the auditor must presume there is a risk of fraud in revenue recognition. This is a rebuttable presumption. So you cannot treat this area as routine. You must plan specific procedures for it. The auditor may conclude that the presumption does not apply only in specific circumstances, and must then document the reasons for that conclusion.

You audit through assertions. For revenue: occurrence (the sale really happened), completeness (all sales are recorded), accuracy (right quantity and price), cut-off (in the right period) and classification (in the right account). For receivables: existence (the debtor is real and owes the money), rights and obligations (the amount is truly the company's, and has not been factored or assigned), completeness, valuation (the amount is recoverable) and presentation and disclosure.

Revenue recognition follows the applicable framework. Under Ind AS 115, revenue is recognised when control of goods or services passes to the customer, at the amount the entity expects to be entitled to. Check the contract terms, delivery terms, returns, discounts and any rights of return. Under AS 9, revenue from sale of goods is recognised when the significant risks and rewards of ownership pass to the buyer.

For receivables, the strongest evidence is an external confirmation from the debtor (SA 505). It comes from outside the entity, so it is more reliable than internal records. Where debtors do not reply, you use alternative procedures: subsequent receipts, dispatch documents and invoices. Then you test valuation using ageing analysis, subsequent recovery, disputes and the provision for doubtful debts.

Key rules to remember

Revenue assertions: Occurrence, Completeness, Accuracy, Cut-off, Classification; Use these as a checklist when asked what the auditor tests in sales.
Receivables assertions: Existence, Rights and obligations, Completeness, Valuation, Presentation and disclosure; Valuation means recoverable amount, net of provision.
Vouching trail for a sale: Customer order → Dispatch / delivery note → Invoice → Sales ledger → Cash receipt; Test both directions: from records to documents (occurrence) and from documents to records (completeness).
Revenue recognition test (Ind AS 115): Recognise revenue when control passes to the customer; Look at delivery terms, acceptance and return rights near year end.
Net receivable: Gross trade receivables − Provision for doubtful debts (expected credit loss); Check the provision basis is reasonable and applied consistently.
Positive vs negative confirmation: Positive: debtor replies in all cases. Negative: debtor replies only if they disagree; Positive gives stronger evidence. Negative suits many small balances with low risk of error.

How to solve Audit of Revenue and Receivables questions

Use this order for any question on sales, revenue or debtors. It keeps your answer complete and easy for the examiner to mark.

1Read the question and identify whether it asks about sales, revenue recognition, debtors, or all three.
2Name the main risk first, such as overstatement, fictitious sales, cut-off errors or irrecoverable debts.
3Link each procedure to an assertion, for example occurrence, cut-off, existence or valuation.
4List the procedures in a logical trail: internal control review, vouching, cut-off, analytical procedures, confirmation, valuation.
5For debtors, state the confirmation type, who controls the process, and what you do for non-replies and differences.
6Cover valuation: ageing, subsequent receipts, disputes, and adequacy of the provision.
7Add presentation points: Schedule III classification, related party balances, and disclosure of ageing.
8Close with a one-line conclusion on the evidence obtained or the effect on the audit report if there is a problem.

Quickest way: Assertion-wise answer grid

When to use it: Use it for 14-mark theory questions or when you are short of time and need a structure fast.

Write two headings: Revenue and Receivables.
Under each, list the assertions in a single line.
Add one or two procedures against each assertion.
For debtors, always include confirmation, non-reply handling and ageing.
Finish with the fraud risk presumption in revenue under SA 240.

Common mistakes in Audit of Revenue and Receivables

Listing procedures without linking them to assertions
Students memorise a vouching list and write it as a single block.
Fix: Tag each procedure with the assertion it tests, such as cut-off or existence.
Forgetting cut-off testing
Students focus on vouching sales during the year.
Fix: Always check sales and returns documents a few days before and after year end, matching dispatch with the invoice date.
Treating a debtor's confirmation as the end of the work
Confirmation looks like conclusive evidence.
Fix: Follow up on differences and non-replies with alternative procedures, and also test valuation, because a debtor can confirm a balance yet be unable to pay.
Letting the client send the confirmation requests
It seems easier and saves time.
Fix: The auditor must control selection, dispatch and receipt of requests, so the evidence stays independent.
Ignoring the fraud risk in revenue
Students think of fraud only in cash or inventory.
Fix: State that SA 240 presumes a fraud risk in revenue recognition and describe responses such as testing journal entries and unusual year-end sales.
Confusing existence with valuation
Both relate to whether the debtor balance is correct.
Fix: Existence asks whether the debtor really owes the amount. Valuation asks whether it will be collected, so use ageing and provisioning for the second.

Worked examples

Example 1

List the audit procedures you would perform to verify sales of a manufacturing company for the year ended 31 March, with the assertion each one addresses.

Show the solution

Understand and test controls over order, dispatch, billing and recording of sales. This supports accuracy and completeness.
Select a sample of sales entries and vouch each to the customer order, dispatch note and invoice. This tests occurrence.
Select a sample of dispatch notes and trace each to the invoice and the sales ledger. This tests completeness.
Check price lists, quantity, GST and arithmetic on invoices. This tests accuracy.
Examine invoices and dispatch records for several days before and after year end, and review credit notes after year end. This tests cut-off.
Compare sales with the previous year, with monthly trends and with gross margin, and investigate unusual changes. This is an analytical procedure supporting all assertions.
Check that sales are separated from other income and that sales returns are properly recorded. This tests classification.
Review Ind AS 115 or AS 9 recognition: when control or risk and reward passed, including sales with a right of return or bill-and-hold terms.

Answer: The auditor vouches sales from records to documents for occurrence, traces documents to records for completeness, checks price and tax for accuracy, tests cut-off around year end, applies analytical procedures, checks classification and confirms that recognition meets the applicable framework.

Example 2

At year end, Shree Traders Ltd has trade receivables of ₹80,00,000. Of these, ₹12,00,000 is from one customer who has not replied to a positive confirmation. The auditor also finds that ₹5,00,000 of the total is over 3 years old. Explain what the auditor should do.

Show the solution

Treat the non-reply as a lack of evidence, not as agreement. Send a second request directly from the auditor, with no involvement of client sales staff, and keep control of the reply.
If there is still no reply, perform alternative procedures on the ₹12,00,000: inspect the sales invoices, dispatch and delivery proof, and customer order.
Check subsequent receipts after the year end from this customer through bank statements, and match them to the specific invoices.
If the amount is not received, review correspondence and ask whether there is any dispute or credit problem.
For the ₹5,00,000 over 3 years old, examine the ageing report, past payment history, any legal action and customer correspondence.
Assess whether the provision for doubtful debts (expected credit loss) is adequate for the old balance and any unreplied balance that cannot be supported.
If the evidence is still insufficient and the effect is material, consider modifying the audit opinion; if the provision is too low, ask management to adjust it first.

Answer: The auditor should not accept the unconfirmed ₹12,00,000 without alternative evidence, should test subsequent receipts and documents, should assess the ₹5,00,000 old balance for recoverability, and should seek an adequate provision. If a material misstatement or lack of evidence remains, the audit opinion must be modified.

Exam tips

For 14-mark questions, structure the answer by assertion. It earns step marks and shows exam-ready thinking.
For MCQs, remember that external confirmation is stronger evidence than internal records, and that existence and valuation are different assertions.
Always mention cut-off for sales, and ageing plus subsequent receipts for debtors. These are the points examiners look for.
Use practical case language, such as 'year-end sales to a related party' or 'unusual credit notes after year end', to show you know the risk.
Connect revenue to SA 240 fraud risk and confirmation to SA 505 where the question asks for standards.

Audit of Revenue and Receivables: frequently asked questions

What is the main risk in the audit of revenue?

The main risk is overstatement, through fictitious sales or sales recorded in the wrong period. SA 240 presumes a fraud risk in revenue recognition, so auditors plan specific procedures such as cut-off tests and analytical review.

Why is debtors' confirmation considered strong evidence?

It comes directly from a third party outside the entity, so it is less open to management influence. The auditor must control the request and the reply. Even so, it mainly supports existence, not full recoverability.

What if a debtor does not reply to the confirmation?

Send a follow-up, then use alternative procedures. These include checking invoices, dispatch records and subsequent cash receipts. If you still cannot get sufficient evidence on a material balance, consider the effect on the audit opinion.

What is the difference between vouching and verification?

Vouching means examining documents that support recorded transactions, such as sales invoices. Verification is wider and covers the existence, ownership and valuation of assets and liabilities. For sales you mostly vouch, and for debtors you verify.
