The revenue is measured to be predictable at the point of sale on the hypothesis that the resulting receivables are valid liquid assets merely pending collection, periodic income will be excessive to the extent of any receivables that eventually become uncollectible. The proper matching of revenue and expense requires that gross sales in the income statement be partly offset by a charge to bad debt expense that is established on an estimate of the receivables arising from gross sales that will not change into cash.
