Quotation generator

Quotation generator

Line items, tax and a validity date built into a printable quotation that says on its face that it is not a tax invoice.

How this is calculated

Each line is quantity x rate; the taxable value is their sum. The tax is that sum at the rate you chose, and the total is the two together. Validity is the quotation date plus the number of days you entered.

  • A quotation is an offer, not a demand and not a tax invoice. The document says so in its footer, because a quotation that uses invoice columns invites a customer to treat it as one.
  • The rate is the one you type. Where an item sits in a different GST slab, quote it on its own line at its own rate or issue a separate quotation; this form carries one rate for the document.

A quotation is an offer, and an offer that does not say when it lapses is an argument waiting to happen. This turns a list of lines into a printable sheet with the tax separated, the total in one place and the date the price stops holding printed on its face.

What makes it a quotation and not an invoice

A quotation asks for an order; a tax invoice demands payment and carries the particulars the law requires for input credit. The two are different documents with different consequences, so the sheet here says in its footer that it is not a tax invoice. That line is not decoration — a quotation laid out in invoice columns is the kind of thing a customer files and later claims was a bill.

The form carries one GST rate for the whole document. Where one item sits in a different slab from the rest, quote it on its own line at its own rate or issue a separate quotation; mixing slabs into a single rate row produces a total nobody can check against the invoice that follows.

Worked through

Ten units at ₹250 is ₹2,500, four at ₹1,200 is ₹4,800, and one installation at ₹7,500 makes a taxable value of ₹14,800. At 18 per cent the tax is ₹2,664 and the quoted total is ₹17,464. Where the supply is interstate the sheet prints a single IGST line; where it is within the state it prints CGST and SGST at nine per cent each, which add to the same figure.

A quotation dated 9 November 2026 with fifteen days of validity lapses on 24 November 2026: the day of the quotation is day zero, and the last day the price holds is the fifteenth. The clause is worth setting from what your costs actually do — a price that holds for a month holds through a supplier increase unless the sheet says otherwise.

Questions readers ask

Should I show GST if I am not registered?

No. Leave the rate empty and the sheet issues the quotation without tax and says so. A total described as inclusive of taxes, with no tax named and no registration behind it, is the sort of line a customer disputes after the work is done.

Does the quotation need to be accepted in writing?

That is a question of contract rather than arithmetic, and this page issues no contract. A signed copy, a purchase order or even an email saying proceed is what most small suppliers rely on, and it is worth keeping whichever one you get.

Can I use this for services rather than goods?

Yes. The lines take a description and an amount, so a service is quoted exactly as a part is. Put the service description and its SAC code in the line text if your customer’s accounts department needs them.
