Why do companies need to create an allowance for doubtful accounts?

Companies create an allowance for doubtful accounts to account for the risk of non-collectible receivables, which helps them present a more accurate picture of their financial health. This estimation reflects the potential losses from customers who may fail to pay their debts, ensuring that accounts receivable are not overstated. By recognizing these anticipated losses, companies can manage their cash flow more effectively and make informed decisions regarding credit policies and risk management. Ultimately, it enhances the reliability of financial statements for investors and stakeholders.
