When you use the direct write-off method, the timing directly changes your income statement and reduces a current asset on your balance sheet. On your income statement, you record bad debt expense at the moment you decide a customer will not pay. You debit <Bad Debt Expense> and credit <Accounts Receivable> for the exact unpaid amount.
This entry increases expenses on your income statement. As a result, your net income drops in the period you write off the account, not when you made the original sale.
This timing can create a mismatch. You may record revenue in one period and the related bad debt expense in a later period. That delay can distort profit trends and make it harder for you to compare results across accounting periods. If the amount is small, the effect may not change decisions. But if the write-off is large, it can significantly reduce reported earnings for that period.
On your balance sheet, when you apply the direct write-off method, you reduce accounts receivable, which is a current asset on your balance sheet. You remove only the specific account that you believe is uncollectible.
You do not create an allowance account. Unlike the allowance method (see below), this approach does not estimate future losses in advance. As a result, your balance sheet may overstate accounts receivable before you record the write-off. It shows the full amount as collectible until you identify a specific bad account.
Once you record the entry, total assets decrease. This reduction also lowers your equity through the drop in net income, which affects your overall financial statements.
