Other Important Aspects

The Auditor should always be careful, while auditing a trading
transaction. Following points need to be considered for the same

Stock in Trade

Correctness and verification of stock-in-trade is of great
importance in any industry. The closing stock of a year becomes
opening stock of the next year, hence constant check on it is
very important. Opening stock + purchase – sale should be equal
to the closing stock. This equation might be true, if there is
any difference due to any reason, the Auditor should check and
verify the reason behind it. Following points need to be
considered while checking and verifying the stock in trade.

  • Sample to customer and the loss of stock during processing,
    loading, unloading, fire and leakage, etc.

  • Sale or purchase in transit.

  • Sale return still excluded in stock and purchase return
    included in stock.

  • Non adjustment of goods received or sent on the sale or
    return basis.

Stock is valued on the basis of physical verification at the end
of the year and should reconcile with the book balance. There
must be effective internal control system to control the stock in

Capital and Revenue Items

The Auditor should always be careful about distinction between
capital and revenue items otherwise profit of the concern will be
overvalued or undervalued and the financial results will not
present true and fair view of the organization.

Current Assets and Fictitious Assets

Over valuation of current assets will represent higher profit and
vice-versa; for example, the inclusion of bad debts in debtor
account. Fictitious assets of no value should be written off like
patents or trademark of no use.

The Auditor should ensure that current assets and fictitious
assets should be valued at actual otherwise profit will
understated or overstated.
