Quotation Format GST: Free Templates in Excel, Word & PDF 2026

A quotation is often the first formal document your potential customer sees from you. Before they sign a contract or issue a purchase order, they have your quote. The quality and professionalism of that quote shapes their decision as much as the price itself.

In India's B2B market, a poorly formatted quotation — one that does not show the GST breakdown, lacks a validity date, or has no terms — signals operational immaturity to the buyer's procurement or finance team. Experienced buyers have seen hundreds of quotes. They know within seconds whether the seller is organized.

A proper quotation format also protects you from disputes. When a buyer approves a quote and later disputes the price or scope, the signed quotation is your legal baseline. Without clear terms — validity period, scope of work, payment schedule, and GST treatment — you have no ground to stand on.

This guide covers exactly what a professional GST-compliant quotation looks like, what fields to include, how to handle tax breakup in the quote, and how to convert an accepted quote directly into a tax invoice. We also cover the free quotation generator from myBillPlease that handles all of this automatically.

Showing GST correctly in a quotation is important for two reasons: it gives the buyer a clear picture of their total cost, and it sets the correct expectation for the tax invoice that follows. A quotation with vague tax treatment ("GST extra" or "plus taxes") is unprofessional and leads to disputes when the invoice arrives.

Always show the pre-GST price and the GST amount separately. Do not quote the inclusive price and hide the tax. For example, if a product costs Rs 10,000 and GST is 18%, show: Unit Price: Rs 10,000 | CGST 9%: Rs 900 | SGST 9%: Rs 900 | Total: Rs 11,800. This is transparent and what the buyer's GST-registered accounts team expects.

Handling multiple GST rates in one quotation: If your quote covers items with different GST rates — common in wholesale, manufacturing, or bundled service+product deals — show the tax calculation for each line separately. In the summary, group tax by rate: CGST + SGST at 5%, CGST + SGST at 18%, etc. Never lump different-rate taxes into one line.

Intra-state vs inter-state: Your quotation should determine whether CGST+SGST or IGST applies based on where you will deliver and where the buyer is registered. If you are in Maharashtra and the buyer is in Delhi, show IGST. If both are in Maharashtra, show CGST+SGST. Get the buyer's state code from their GSTIN (characters 1-2 of GSTIN indicate the state).

Validity and rate changes: If GST rates change between the quotation date and the date of supply, the rate applicable on the date of supply governs. Always include a clause in your quotation: "GST charged will be as per the rate applicable on the date of invoice." This protects you if rate changes happen during a long project.

Use the myBillPlease quotation generator to auto-handle intra vs inter-state GST logic based on your buyer's address.

The validity period is one of the most important and most overlooked fields in a business quotation. Without a validity date, your quotation is technically an open offer — a buyer could come back 6 months later and demand you honor the quoted price. That is both impractical and legally risky if your costs have changed.

Standard validity periods by industry:

Trading and distribution businesses typically quote for 7-15 days — prices for commodities and imported goods can change quickly. Service businesses (IT, consulting, marketing) usually quote for 30 days. Manufacturing businesses with stable raw material costs quote for 15-30 days. Construction and infrastructure quotes have validity of 60-90 days given the project timeline complexity.

What happens after validity expires: If a buyer wants to accept a quotation after the validity date, you have three options: reissue the quotation at current prices, honor the old price as a goodwill gesture, or negotiate a revised price. Always communicate this in writing before proceeding. Do not issue a tax invoice at the old price if costs have changed significantly — it affects your margins and may not reflect actual market rates.

Terms and conditions that should always appear:

1. Payment terms: Be specific. "50% advance with purchase order; balance 30 days from invoice date" is better than "payment by advance."

2. Cancellation clause: "Cancellation after PO acceptance attracts 25% of order value." This protects you for custom or manufactured orders.

3. Force majeure: "Delivery timelines subject to change due to circumstances beyond our control." Protects against supply chain disruptions.

4. Dispute resolution: "Disputes subject to [city] jurisdiction." Establishes the legal forum.

5. GST applicability: "All prices exclusive of GST. GST will be charged at the rate applicable on the date of invoice."

When a buyer approves your quotation — by signing and returning it, or by issuing a purchase order referencing your quote number — the next step is to create a formal tax invoice. This is where disconnected tools create problems.

If you created your quotation in Word and now need to create an invoice in Excel, you are re-entering all the same data: customer details, line items, quantities, prices. This takes 10-15 minutes per invoice and introduces transcription errors. A mistyped quantity or price on the invoice that differs from the approved quotation is a compliance and trust issue.

The right approach is to convert quotes to invoices, not re-create them. In myBillPlease, when a quotation is accepted, you click "Convert to Invoice" from the quotation screen. The system copies all data — customer details, line items, HSN codes, quantities, prices, and GST rates — into a new invoice. The invoice date defaults to today, and you get a fresh invoice number. You can make minor adjustments (if the buyer changed quantity or added items) before saving.

The quotation number can be referenced in the invoice as a custom field: "Against Quotation: QT-2026-0089 dated 15-Mar-2026." This creates the paper trail that buyers' accounts teams and auditors expect to see.

After converting, the quotation status changes to "Accepted" in the system, and the invoice is linked back to the quotation for reference. If the buyer later raises a query about pricing, you can show the full history: original quote → buyer approval → invoice. Try this workflow with the free quotation tool — the quote-to-invoice conversion takes 30 seconds.
