慶英会 塾長|慶應義塾大学卒・英検1級
中高一貫校の学校英語・NEW TREASURE・英検対策を専門とするオンライン個別指導塾です。塾長紹介
英検2級のEメールや説明文でestimate・quotation・invoice・receipt・purchase orderを一律に「書類」と読むと、支払済みかどうかを取り違えます。estimateは概算、quotationは条件付きの見積提示、purchase orderは発注書、invoiceは請求書、receiptは支払・受領の証拠です。depositは前金、balanceは残金を指します。
慶英会が制作した英検2級向けの無料オリジナル教材です。学校展示・科学センター・図書館・学校新聞という架空の4長文40問で、数値・請求期限・書類の発行順を練習します。全問4択・正答と英文根拠、長文の全文和訳付き。公式の過去問ではありません。
estimate・quotation・invoice・receiptの違い
| 英語 | 意味と注意点 |
|---|---|
| estimate | 概算・推定金額。最終額は条件により変動し得る |
| quotation / quote | 指定された内容と条件に対する見積提示 |
| purchase order | 買い手側が数量・価格等を記載して行う発注書 |
| invoice | 売り手から買い手への請求書。支払が完了したこととは別 |
| receipt | 代金を受け取ったことを示す領収書・受領記録 |
| deposit / balance | 前金/残金 |
| credit note | 請求額・債務の減額を示す書類。必ずしも返金の証拠ではない |
書類の典型的な流れ:見積の依頼→見積提示→条件の受諾・発注→請求→支払→領収。ただし実際の順序や前金の有無は取引条件によって変わるため、本文の具体的な記述が優先です。
英検2級の公式試験内容では、長文内容一致8問(Eメール・説明文)が出題されます。ここでは取引・支払に関する読解を独自40問で補強します。英検協会の2級試験内容
独自長文1|学校の展示パネル|estimateとfinal invoice
Subject: Cost Estimate for the School Exhibition Dear school committee, Thank you for asking us to produce ten display panels. Our preliminary estimate is 48,000 yen, including printing and basic delivery. This estimate is based on the current design, but the final amount could change if the committee requests thicker materials or additional editing. We can provide a fixed quotation after you approve the final artwork and tell us which material you prefer. A quotation is an offer of specified work at a stated price under its terms. The current estimate is not the final quotation and should not be treated as an invoice. The school has not yet placed an order. If the committee accepts our quotation, we will issue an order confirmation and start production. We will send the invoice after the panels have been produced, with payment due within fourteen days of the invoice date. Please do not transfer the estimated amount now. We have not requested payment, and a bank-transfer record would not prove that the panels have been completed. Display Printing Team

学校の展示パネル見積。学校委員会が展示パネル10枚の制作を問い合わせ、現時点で印刷と基本配送込みの概算見積が48,000円と提示されました。デザインや厚い素材への変更、追加編集によって最終額は変わり得ます。最終デザインと素材が決まれば、条件・価格を定めた確定見積書quotationを発行できます。現時点のestimateは確定見積でも請求書invoiceでもありません。学校はまだ注文しておらず、確定見積を受諾した後に注文確認を発行して製造します。パネル完成後に請求書を送り、その日付から14日以内が支払期限です。現時点で見積額を振り込まないでください。まだ請求はなく、振込記録だけで製品完成の証明にもなりません。
独自長文2|地域科学講座の費用|quotation・deposit・balance
Workshop Equipment: Quotation and Payment Terms A community science center needs six microscopes for its weekend program. Supplier A offers a quotation of 72,000 yen for the six microscopes, valid until July 20. This quotation includes delivery but not optional storage cases. Supplier B gives an estimate of approximately 68,000 yen, with the final price dependent on availability. The center cannot assume that Supplier B’s final charge will be lower. On July 18, the center accepts Supplier A’s quotation. Under the agreed terms, the center must pay a deposit of 18,000 yen before the goods are dispatched. The remaining balance is 54,000 yen, payable within ten days of receiving the microscopes. The supplier sends a deposit invoice first. The center transfers 18,000 yen and receives a receipt confirming that this deposit has been paid. The receipt does not mean the entire 72,000 yen bill is settled. A separate invoice for the outstanding balance will follow delivery. The supplier expects to dispatch the microscopes on July 22. Dispatch is not the same as delivery, so the center should not calculate the balance deadline from July 22 unless the goods arrive that day. Science Center Treasurer

地域科学センターは週末講座用に顕微鏡6台を必要としています。A社は配送込み・収納ケース別で7月20日まで有効な72,000円の確定見積を提示しました。B社は約68,000円の概算見積ですが在庫によって最終価格が変わるため、B社が必ず安いとは言えません。センターは7月18日にA社の条件を受諾しました。契約では発送前に18,000円の前金depositが必要で、残金54,000円は顕微鏡受領から10日以内の支払です。まず前金の請求書が送られ、18,000円の振込後、その支払を証明する領収書が発行されます。ただし領収書は全額72,000円の支払済みを意味しません。残金の別請求書は配送後に届く予定です。発送見込みは7月22日ですが、発送と到着は別なので受領日が同じでない限り残金期限を22日から計算すべきではありません。
独自長文3|図書館修理費の請求|invoice・receipt・credit note
Library Repair: Understanding the Final Bill A town library arranged repairs to twelve damaged chairs. The workshop’s quotation was 36,000 yen for the agreed repairs. After starting the work, the staff discovered that two chairs were beyond safe repair. The library and workshop agreed not to charge for repairs that had not been performed on those two chairs. The workshop issued an invoice of 36,000 yen before applying the adjustment. It then sent a credit note for 6,000 yen to reduce that invoice. The corrected amount payable was therefore 30,000 yen. A credit note reduces an amount owed; it is not, by itself, proof that a cash refund has already been transferred. The library paid the corrected 30,000 yen by bank transfer on November 5. The workshop then issued a receipt showing the payment date and amount. The invoice requested payment, while the receipt provided evidence of payment received. The two unsafe chairs were returned to the library with a recommendation that they not be used. Their replacement was not included in the repair quotation, so the library would need a new estimate if it wanted to buy new chairs. Library Facilities Office

図書館は壊れた椅子12脚の修理を依頼し、見積は36,000円でした。しかし着手後に2脚が安全に直せないと分かり、行わなかった2脚の修理代は請求しないことで合意しました。工房はいったん36,000円の請求書を出しましたが、6,000円減額するcredit note(クレジットノート)を発行し、修正後の支払額は30,000円になりました。クレジットノートは債務を減らす書類で、すでに現金が払い戻された証拠ではありません。図書館は11月5日に30,000円を振り込み、工房はその日付と額の領収書を発行しました。invoiceは支払を要求する書類、receiptは受領済みの支払証拠です。直せない2脚は使用しないよう提案して返却され、交換用の新品椅子は元の修理見積に含まれないため、新たな見積が必要です。
独自長文4|学校新聞の印刷注文|purchase order・invoice・receiptの順序
Printing the School Newspaper The student newspaper team asked a printing company for prices for 500 copies of its special edition. The company issued a quotation of 25,000 yen for black-and-white printing, excluding any changes to the artwork after approval. The quotation was valid for ten days. The school accepted the quotation and sent a purchase order, which formally listed the number of copies, agreed price, delivery address, and requested date. Sending a purchase order was the school’s way of placing the order under the agreed terms. The printer then sent an order confirmation. The newspapers were delivered on February 14. Staff checked the number of copies and reported that ten copies had damaged covers. The printer agreed to provide ten replacement copies without an additional charge. It sent an invoice for the original agreed total of 25,000 yen; the replacements did not add to the amount due. The school paid on February 20 and received a receipt that day. The receipt recorded that payment had been received, not that the newspaper team had won a competition. The newspaper committee stored the purchase order, invoice, and receipt together so it could check the transaction later. School Newspaper Team

学校新聞の特別号500部の印刷について、印刷会社は白黒印刷25,000円、デザイン承認後の追加変更は対象外という10日間有効の見積を出しました。学校はこれを受け入れ、部数・合意価格・配送先・希望日を記した発注書purchase orderを送りました。会社は注文確認書を返信しました。新聞は2月14日に届き、確認すると10部の表紙に傷みがあったので、会社は追加料金なしで10部を交換することにしました。請求書は元の25,000円のままで、交換分は増額されません。学校は2月20日に支払い、同日領収書を受け取りました。領収書は支払受領の記録で新聞の受賞を証明するものではありません。委員会は後日確認できるよう発注書・請求書・領収書を保管しました。

|---|---|---|---|
| 学校展示 | 概算48,000円 | 未請求 | 確定見積受諾後に発注 |

3段階の解き直し
初回は40問を解いて、請求か支払済みかを一つずつ記録します。翌日は数字の単位・支払期限を確認し、72,000−18,000=54,000円、36,000−6,000=30,000円などの計算を再確認。7日後は英文を読んで、どの書類が発行済みか、何が未完了かを説明できるか試してください。
FAQ
invoiceが届けば支払った証拠ですか?
いいえ。invoiceは支払を求める請求書です。支払済みの証拠としてreceiptが発行される場合があります。
estimateとquotationは完全に別の意味ですか?
実務で意味が重なることはありますが、本教材の例ではestimateは変更可能な概算、quotationは条件を特定した見積提示です。実際の取引では文書の条件を確認します。
credit noteは必ず現金が戻った意味ですか?
いいえ。請求額や債務の減額を示すことがあり、現金の返金が完了したかは別の確認が必要です。
英検の公式過去問ですか?
いいえ。慶英会が独自に作成した補強教材です。
