Roy B. Kester, Accounting theory and practice… (1922)
“ When the invoice covering any purchase is received, it is held till the commodities bought arrive. After inspection and acceptance of the goods, a voucher is made out in duplicate on which is written a copy of the invoice, with the cash discount, if any, shown deducted. Vouchers are given consecutive numbering just like checks. If immediate payment is to be made, the voucher will be “approved” and check drawn for the amount. The voucher with check attached is sent to the creditor with a request that he receipt the voucher and return it. ”
