How to Write a Japanese Estimate (見積書)
This guide explains the role of Japanese estimates (見積書), what to include, and the key points that prevent misunderstandings.
Overview
What Is a Japanese Estimate (見積書)?
An estimate proposes price, quantity, and delivery terms before a contract. It is not legally required, but it improves transparency and reduces disputes by making conditions clear.
Role in the Business Flow
Typical flow: inquiry → estimate → order/acceptance → delivery → invoice. The estimate is the agreement baseline for scope, schedule, and cost.
Essential Items
Typical Items to Include
Include the following items to make the estimate clear and easy to approve.
Document title
Use "Estimate (見積書)" so the purpose is explicit.
Issue date
Date the estimate was created.
Validity period
Include the expiration date for this estimate.
Estimate number
Use sequential IDs for tracking and reference.
Issuer information
Company/personal name, address, and contact info. A seal is optional but adds formality.
Recipient information
Client name and optional department/person. Avoid duplicate honorifics.
