解説

問 33

  • Incorrectア

    A proposal is a document that the receiving party submits to the ordering party before the contract to present the content of its proposal, so it belongs to the stage before the contract is concluded and falls outside the range from after the contract until payment. In addition, it lacks the invoice needed to claim payment, so the documents leading up to payment are not complete.

  • Incorrectイ

    Both the proposal and the quotation (a document that presents the amount) are exchanged before the order amount is fixed and the contract is concluded. Since the question asks about documents after the contract, this combination, which includes two pre-contract documents, is inappropriate.

  • ウ

    正解 The business proceeds along the flow: proposal → quotation → (order amount fixed) → conclusion of the contract for work → delivery → acceptance → payment. The question asks about the documents exchanged from after the contract is concluded until payment. After the contract, the receiving party first issues a delivery note when handing over the deliverables; next the ordering party, after confirming the content is satisfactory, issues an acceptance certificate; and finally the receiving party issues an invoice to claim payment. All three of these are exchanged after the contract and before payment, so the correct combination is ウ (delivery note, acceptance certificate, invoice).

  • Incorrectエ

    A quotation is a pre-contract document used to fix the order amount, so it does not fall within the post-contract range. It is also insufficient in that it lacks the acceptance certificate that the ordering party issues after confirming the deliverables following the contract.

ここがポイント
  • Being able to distinguish the timing of each document within the transaction flow of system development (proposal, quotation → conclusion of contract → delivery note → acceptance certificate → invoice).
  • Understanding the positioning that the proposal and quotation are pre-contract documents, whereas the delivery note, acceptance certificate, and invoice are documents exchanged from after the contract until payment.
