How you will work through this lecture
The client reports receivables of 2,450,000.00 and selections of 620,000.00. Invoices exist, but an external reply of 180,000.00 conflicts with 230,000.00 and the ageing has no extraction parameters. Define existence, cut-off and accuracy assertions, test the population and report, resolve 50,000.00 and combine confirmation, cash and delivery evidence.
Audit evidence begins with management's assertion, not the document nearest at hand. For a 2,450,000.00 receivable balance, invoices alone do not prove existence, cut-off, rights or collectability. Write a falsifiable question about real customers, delivery before 31/12/2026 and recorded amount. Every procedure then has a purpose, and no single document is mistaken for proof of every assertion.
Sufficiency is not page count or a fixed population percentage. More evidence is needed as misstatement risk, estimation uncertainty, control weakness or contradiction rises. A 620,000.00 selection from 2,450,000.00 must explain large-item coverage, remainder and non-responses; value coverage alone does not prove representativeness. Revise the planned extent when results change.
Appropriate evidence is relevant to the assertion and reliable enough for the conclusion. A signed contract does not prove delivery; a current screenshot may omit extraction parameters. Reliability rises with independent origin, direct auditor control, tested systems and reperformance, but labels are not enough. A confirmation reply forwarded by management is not independent merely because it bears a customer name.
Existence and completeness require opposite directions. Recorded sales are traced from ledger to order and delivery; unrecorded liabilities are searched from subsequent invoices, receipts or payments back to the books. Selecting only recorded entries cannot reveal omitted liabilities. State the start and destination of every procedure so a neat zero does not hide the wrong search direction.
Inquiry explains but rarely proves; inspection shows a record; observation covers a moment; reperformance independently tests; confirmation can provide controlled third-party evidence; analytics needs a precise expectation and reliable data. Combine procedures with different error mechanisms. Repeating invoice inspection four times is not corroboration.
A customer confirming 180,000.00 against a 230,000.00 ledger balance creates a 50,000.00 investigation, not an automatic journal or discarded reply. Separate timing, dispute, entity mismatch and error; test management's reconciliation inputs. Contradictory reliable sources may change risk and further work. The conclusion explains resolution item by item, not a small net.
The treatment starts from these documents. Follow the numbers to identify recognition date, amount, counterparty, reference and approval evidence before preparing the entry.
Facts and supporting evidence
Bank evidence proved 30,000.00 collected before close but not posted to the customer.
Correct treatment and entry
| Account | Debit | Credit |
|---|---|---|
| Cash at bank | 30,000.00 | |
| Trade receivables | 30,000.00 | |
| Total (SAR) | 30,000.00 | 30,000.00 |
Treatment and financial effect
It corrects the independently supported item and leaves the remainder open.
Reperformance starts from this case's own facts: Bank evidence proved 30,000.00 collected before close but not posted to the customer. Obtain the original source that proves this event. The training drawings Receivables evidence matrix, Contradictory reply bridge explain field shape and reading order; they do not replace the case document or transfer their figures into it. Match entity, period, currency, reference and version to the trial balance, assertion, population and internal or external evidence, then confirm that the source supports the debit side (Cash at bank) and the credit side (Trade receivables). Missing ownership, date, reference or approval remains an open exception; a balancing journal or undocumented assumption does not cure it.
Remeasure from the facts before reading the proposed journal, then add it independently: total debits 30,000.00 and total credits 30,000.00. Debit detail: Cash at bank for 30,000.00. Credit detail: Trade receivables for 30,000.00. Link every line to the recognition or measurement rule explained in the lecture, then trace its reference and posting date. After posting, test the audit workpaper, reperformance and cross-references. Equal sides prove arithmetic only, not the correct account, period or classification.
Before close, compare the correct treatment with the common alternative and record its specific effect: Cash is understated and suspense overstated by 30,000.00. Do not close until the journal agrees with the procedure conclusion, misstatement schedule and client communication and an independent reviewer can move from balance to account, reference and this event's own source. Keep the calculation, source version, journal identifier, reconciliation result and unresolved exceptions in the same workpaper. An attached file without a stated conclusion is not review evidence.
The audit file retains population version, report parameters and fingerprint and links each selection to assertion, procedure, evidence and result. Client access can upload but cannot alter auditor judgement or direct replies; version history preserves contradictions and resolution.
Build the 2,450,000.00 receivables matrix: map 620,000.00 selections to assertions, test the ageing and open the 50,000.00 reply difference into independent evidence.

Strong evidence answers a defined assertion through a correctly directed procedure and tested source. Sufficiency follows risk and quality, entity information needs testing, contradictions remain visible until resolved, and conclusions state coverage and limits.
How do 620,000.00 of receivable selections support a 2,450,000.00 balance without treating invoices or coverage as universal evidence?
Answer every question. Getting them all right records this lesson; you may retry as often as you need.
Reading alone records nothing.
The complete applied walkthrough is available below while the recording is prepared.
Begin with the assertion: do recorded receivables exist and belong in the period? Prove the 2,450,000.00 population and ageing parameters before selecting 620,000.00. An invoice does not prove delivery or cash. A 180,000.00 reply against 230,000.00 opens 50,000.00; test 30,000.00 through bank and date and retain 20,000.00 until further procedure or difference. Combine confirmation, cash and delivery because they expose different errors. Conclude only within tested coverage.
Audit procedures often rely on ageing reports, shipment lists, journal extracts or management schedules. Fix report name, parameters, period, entity, currency, status, extraction time and control total; tie to the ledger and test calculated fields and manual changes. A 2,450,000.00 tie does not validate ageing logic or excluded credits. A client spreadsheet is another assertion until origin, completeness and accuracy are tested.
An estimate has no single invoice that proves it. Test the method, data, assumptions, calculation and disclosure. A 145,000.00 credit allowance may calculate correctly while default data are incomplete or forecasts biased. Compare assumptions with history, external sources and later outcomes; consider a range or independent estimate and inspect directional bias across estimates.
Professional scepticism means remaining alert to incomplete or misleading evidence and changing work when indicators arise, without treating every client interaction as accusation. Investigate changed populations, common reply addresses or missing originals through independent routes. Neither prior-year familiarity nor blanket distrust replaces current evidence. Document the indicator, response and result.
Audit work neither pursues every theoretical possibility nor stops when the time budget expires. Ask whether procedures cover assertion, population and period, contradictions are resolved and remaining risk could change the conclusion. If appropriate evidence is unavailable for 410,000.00, perform alternatives or evaluate a scope limitation; management representation cannot replace missing evidence. State what was and was not supported.
Facts and supporting evidence
A DAP contract and post-year customer acceptance proved 80,000.00 revenue was recorded before control transferred.
Correct treatment and entry
| Account | Debit | Credit |

| Contract liabilities | 80,000.00 | |

It reverses premature recognition while retaining the billed amount as a performance obligation.
