Roy B. Kester, Accounting theory and practice… (1922)
“ It is true that in some instances the profit and loss summary is mistakenly made up on a so-called cash basis, cognizance being taken of the income and expense items only when realized in cash. It would hardly seem necessary to convince the modern business man that sales made on credit and not yet realized in cash are part of his income as much as the items of income realized in cash, the chief difference being that provision must be made in the one case for uncollectible items, while in the other case no such provision is necessary. ”
