What is the percentage-of-receivables method?

The percentage-of-receivables method is a way for a company to estimate its Allowance for Uncollectible Accounts and Bad Debt Expense. It is considered a "Balance Sheet Approach," because total Allowance for Uncollectible Accounts is estimated as a percent of total Accounts Receivable. Bad Debt expense then becomes the increase between the previous year's Allowance and the current year's Allowance.
