How to write a quotation
By Shivam Bhandari · Reviewed 31 October 2026 · How we write
A quotation tells a prospective customer exactly what you will supply, at what price, and on what terms, before they place an order. It helps customers compare suppliers and gives you a clear record if the price is later questioned.
Unlike an invoice, a quotation doesn't ask for payment. Once accepted, it usually becomes the basis for a purchase order and then an invoice.
What to include
- Your business details and GSTIN
- Unique quotation number and date
- Customer details
- Item-wise description, quantity, rate and amount
- GST rate and amount, and total
- Delivery timeline, payment terms and validity date
Tips
- 1Number every quotation so you can track which ones convert.
- 2Set a validity date — input prices can change.
- 3Show GST separately so business customers can claim input tax credit.
- 4Follow up within two or three days of sending.
Frequently asked questions
What is the difference between a quotation and an invoice?
A quotation offers a price before an order is placed; an invoice requests payment after goods or services are supplied.
Is GST mentioned on a quotation?
It's good practice to show the GST rate and amount so the customer knows the total cost.
How long should a quotation be valid?
Commonly 15 to 30 days, depending on how quickly your costs change.
Is a quotation legally binding?
It's an offer. Once the customer accepts it, it can form part of a contract, so make sure terms are accurate.
