Answer:
The most accurate statement is:
d. The allowance method is the accepted method because it follows the expense recognition (matching) principle.
Step-by-step explanation:
The difference between the direct write-off method and the allowance method is that with the direct write-off method, the bad debt expense is created once an invoice cannot be paid by the customer. On the other hand, the allowance method estimates the future bad debt and makes provision for it immediately a credit sale is finalized. The direct write-off method is favored by the IRS, while GAAP approves the allowance method.
