Estimation vs Quotation: When to Use Each Document
Understand the exact difference between an estimation and a quotation, when each should be used, and how to avoid pricing confusion with clients.
Clients often ask for "a quote" even when they actually need an estimation first. Choosing the wrong document creates pricing conflicts later.
Estimation: early-stage pricing
An estimation is used when scope is still being discovered. It gives a realistic cost range and major assumptions, but it is not a final commitment.
Quotation: final commercial offer
A quotation is sent after scope is locked. It contains final line items, taxes, terms, and a fixed amount for approval.
Easy rule of thumb
If requirements can still change, send an estimation. If requirements are approved, send a quotation.

What to include in both

- Line items and taxes
- Validity and payment terms
