When do you need this document

A quotation is a formal commercial document sent by a supplier or service provider to a prospective buyer before any work starts or goods are dispatched. You need a quotation whenever a client requests an official estimate of costs, project scope, and completion timeframes. Submitting a clear written quotation establishes agreed pricing boundaries and protects both parties against unexpected scope disputes.

It is essential to understand how a quotation differs from a proforma invoice and a statutory tax invoice. A quotation is an exploratory pre-sales proposal that does not demand payment and carries no tax liability. A proforma invoice is issued after negotiations conclude to request an advance deposit or facilitate customs pre-clearance. In contrast, a statutory tax invoice is issued under Section 31 of the CGST Act at or before delivery, serving as the legal instrument creating tax liability and supporting input tax credit claims.

What the document must contain

A comprehensive commercial quotation should clearly outline every element of the transaction:

  • Quotation reference number and calendar issuance date
  • Supplier identity, including registered trading name, address, email, and phone number
  • Prospective buyer details, including company name and designated contact person
  • Granular scope rows detailing itemized goods, service deliverables, or project phases
  • Unit prices, quantities, and applicable tax rates indicating whether figures are inclusive or exclusive of GST
  • Explicit quotation validity date defining when the proposed pricing expires
  • Commercial payment milestones, deposit terms, and delivery schedules
  • Terms and conditions governing scope adjustments, cancellations, and client responsibilities

Common mistakes

Avoid these frequent commercial errors when issuing price quotations:

  • Omitting quotation expiration dates: Without an expiry date, buyers may attempt to lock you into quotes months later after your underlying labor or material costs have risen. Standard practice is a 15 to 30 day validity window.
  • Vague scope descriptions: Using broad descriptions such as software work or renovation without itemized deliverables causes scope creep during execution.
  • Unclear tax treatment: Failing to specify whether quoted rates include or exclude GST leads to disputes upon final invoice delivery.
  • Treating a quotation as a tax invoice: A quotation cannot be used to demand final payment or report sales turnover for GST returns.

Frequently asked questions

An expiration date protects your business against inflation, currency fluctuations, and supplier price increases. Specifying a validity period of 15 or 30 days ensures that if a client delays signing, you retain the legal right to revise cost estimates before commencing work.
Yes. Under Indian contract law, when a prospective buyer accepts a formal written quotation without material amendments, an enforceable commercial agreement is established based on the quoted deliverables and terms.
Once the project is delivered or milestones are achieved, you issue a statutory tax invoice under Section 31 of the CGST Act referencing the quotation number, itemizing actual deliverables, and calculating statutory CGST, SGST, or IGST.
