Substantive testing for the transaction cycle is one of the procedures that external auditors perform during an audit to obtain evidence of the completeness, accuracy, and validity of transactions recorded in the financial statements. In the case of teeming and lading, substantive testing for the transaction cycle can help auditors to detect this type of fraud.

• Analytical procedures: Auditors can compare the accounts payable balance with the previous year’s balance, industry benchmarks, and the company’s sales. Any significant fluctuations in the accounts payable balance can be investigated further to determine the reasons behind the change.
• Testing of documentation: Auditors can select a sample of invoices and payments from the accounts payable ledger and examine the supporting documentation such as purchase orders, receiving reports, and vendor invoices. This can help auditors to verify the existence and authenticity of the transactions.
• Independent confirmation of accounts payable balances: Auditors can send confirmation requests to the company’s suppliers to confirm the accuracy and completeness of the accounts payable balance. Confirmation responses from suppliers can provide auditors with evidence that the accounts payable balance is complete and accurate.
• Physical inspection of inventory: Auditors can observe the physical inventory and compare it to the inventory records, purchases, and accounts payable ledger. Any discrepancies in the inventory records can indicate the existence of fictitious transactions.

In conclusion, substantive testing for the transaction cycle can be effective in detecting teeming and lading fraud in a company. Auditors must exercise professional skepticism and perform due diligence to detect any fraudulent activity in the financial statements.
