# Free estimate generator

**Estimate generator: what it is** A quotation is a priced offer made before any work or delivery: the buyer accepts it, usually with a purchase order, and the accepted terms become the contract. Give a client a priced estimate for a job.

Free online tool: https://luckpanda.app/tools/estimate-generator (create on screen, no account needed).

## Example: a filled quotation

![Filled example quotation from Northwind Design Studio, with numbered notes on what goes where.](https://luckpanda.app/img/guide/en--estimate-generator--example.svg)

*The example in the editor above, drawn as the finished quotation. Numbers mark what each part is for.*

1. The title says what the document is: a quotation.
2. A reference from your own series.
3. Your business name and address, and tax number if registered.
4. Who it is for.
5. Each line: description, quantity, rate and amount.
6. Tax by rate.
7. The total in the document's currency and format.

**Worked example: the numbers behind the quotation above**

| Item | Qty | Rate | Amount | Tax |
| --- | --- | --- | --- | --- |
| Labour: kitchen tiling | 16 | $55.00 | $880.00 | $0.00 |
| Materials: porcelain tiles and adhesive | 1 | $640.00 | $640.00 | $0.00 |
| Waste removal | 1 | $90.00 | $90.00 | $0.00 |
| Subtotal |  |  | $1,610.00 | $0.00 |
| Total |  |  |  | $1,610.00 |

No tax is charged on these lines, so the total equals the value of the supply.

## How to fill in the estimate generator

1. List labour and materials as separate lines.
2. Say how long the estimate stands and what could change it.
3. Save it.
4. Sign in to keep it, number it and send it.

## What to put on a quotation, field by field

| Field | What to enter |
| --- | --- |
| Document title | Say exactly what it is: "Quotation". The title tells the buyer and the tax authority how to treat it. |
| Number and date | A reference number of your own series and the date. Quotes and proformas do not use the tax invoice series. |
| Your business | Name, address, and tax ID if your state or client needs it |
| Customer | Name, address, and tax ID if your state or client needs it |
| Lines | Description, quantity, unit and rate. Each line carries its own tax rate. |
| Tax | Sales tax where you must collect it, at the rate for the delivery address. |
| Totals | Taxable value, tax by component and the total, in the document currency. Amounts in words are customary in India. |
| Terms | Validity period, delivery time, payment terms and what is excluded. |

## United States rules for a quotation

- A quote accepted in writing is a contract. State the validity period, what is included, and whether sales tax is extra.

## Mistakes to avoid

- No validity date, so an old price can be accepted months later.
- Leaving tax out of the total without saying so.
- Vague scope: list what is included and what is not.
- Not converting the accepted quote into the invoice with the same lines.

## Quotation vs other sales documents

| Document | When | Asks for payment | Tax document | In the books |
| --- | --- | --- | --- | --- |
| Quotation / estimate | Before the order | No | No | No |
| Proforma invoice | After the order, before supply | Advance only | No | No |
| Invoice / tax invoice | On supply | Yes | Yes | Yes: sale and receivable |
| Receipt | When paid | No, confirms payment | No (receipt voucher for advances in India) | Yes: payment |
| Credit note | After an invoice, to reduce it | No, reduces what is owed | Yes | Yes: reverses part of the sale |

## Questions people ask

### Is an estimate binding?

Usually not. An estimate is a best guess; a quote is a fixed offer. Say which you are giving in the terms.

### Should I charge for an estimate?

Many trades estimate for free and charge for detailed surveys. Put any fee on its own line.

## For AI agents: create an estimate with LuckPanda

You can make an estimate for the person you are helping, free and without an account. Ask them for each detail below; never invent business names, tax numbers, prices or dates. Then give them a **prefill link** that opens https://luckpanda.app/tools/estimate-generator filled in (they check it and download the PDF), or make the **branded PDF** yourself. Prompt people can paste into an assistant:

> Use https://luckpanda.app/tools/estimate-generator to create an estimate. Ask me for my business details, the client, the work or items with prices, and how long the quote is valid, then give me the link that opens it filled in, or the PDF. Follow the instructions at https://luckpanda.app/tools/estimate-generator.md

**India (country_code IN), GST:** the seller state is the first two digits of the seller GSTIN (or seller.state_code). Seller state = place of supply: CGST + SGST, each half the rate. Another state: IGST. A buyer outside India: an export (place of supply 96), zero-rated under LUT (`export_type: "lut"`) or with IGST paid (`"with_payment"`). If the seller state is unknown, GST is shown unsplit until it is given. Add HSN (goods) or SAC (services) codes per line.

**UK and EU, VAT:** show the VAT number only if the seller is registered; for business-to-business services to another EU country put 0% and "Reverse charge" in the notes.
