領収書には規定のフォーマットが存在する？
There is usually no set form for a receipt, such as a requirement that it be machine generated. Many point-of-sale terminals or cash registers can automatically produce receipts. Receipts may also be generated by accounting systems, be manually produced or generated electronically, for example if there is not a face-to-face transaction. To reduce the cost of postage and processing, many businesses do not mail receipts to customers, unless specifically requested or required by law, with some transmitting them electronically. Others, to reduce time and paper, may endorse an invoice, account or statement as "paid".
