The Link between the Trial Balance, Closing Inventory and Financial Statements

Where Closing Inventory Sits

Closing inventory is the value of unsold stock at the end of the accounting period. It does not appear inside the trial balance because its value is only known after a stock-take on the closing date, which happens after the trial balance has been extracted. It is therefore written as a note below the trial balance. Only opening inventory appears in the trial balance (a debit balance).

How Items Flow to the Statements

• Revenue and expense accounts (sales, purchases, rent, wages) → transferred to the Trading and Profit & Loss Account.
• Asset, liability and capital accounts → carried to the Statement of Financial Position.
• Opening inventory → entered in the Trading account (part of cost of sales).
• Closing inventory → deducted in cost of sales and listed as a current asset.

The Relationship in Brief

The trial balance provides the figures; closing inventory is added as adjustment information; together they build the Trading and Profit & Loss Account and the Statement of Financial Position. Without the closing inventory value, cost of sales and gross profit cannot be calculated correctly.

Because closing inventory affects both statements, an error in valuing it has a double effect: gross profit and net profit are misstated, and total current assets in the Statement of Financial Position are also wrong. That is why the stock-take at the closing date must be done carefully and valued at the lower of cost and net realisable value, in line with MFRS.
