Many freelancers, contractors, and emerging entrepreneurs confuse a quotation with an invoice. While both documents detail products, services, and costs, they serve entirely distinct purposes in the sales lifecycle.

The Fundamental Distinction

  • A Quotation (also called an Estimate or Quote) is sent before work begins or goods are delivered. It is a proposed price offer that outlines project scope, timelines, and payment milestones. Once accepted, it forms the basis of a contract.
    • An Invoice (or Bill) is sent after delivery or milestone completion. It is a formal demand for payment and legally records a completed tax event.

      | Feature | Quotation | Tax Invoice | |---|---|---| | Timing | Prior to agreement/order | After completion or delivery | | Legal Nature | Commercial proposal | Legal demand for payment & tax record | | Accounting Impact | No ledger entry; non-taxable | Recorded in sales ledger & GST returns (GSTR-1) | | Input Tax Credit | Cannot be used for ITC | Eligible for recipient's ITC | | Validity | Contains expiry date (e.g. 15 or 30 days) | Contains due date for payment |
