What is a quotation?

A quotation (ใบเสนอราคา) is a price offer for goods or services, sent before the customer agrees to the work. Once accepted, it records the price, the scope and the payment terms.

A quotation is not a tax document — it is neither a tax invoice nor a receipt. We found no legally prescribed format for a quotation, but a good quotation carries the items below.

What a quotation should include

Your name, address, tax ID and contact details
The customer’s name and address
Quotation number and date
How long the price is valid
Items or work, quantity, unit, unit price and amount
Discount, VAT 7% (VAT-registered businesses only) and the total
Payment terms, e.g. deposit and stages
Signature lines for you and the customer

What GlideQuote does

Make the quotation on your phone with GlideQuote

Add the customer and items — items you use often are saved and added in a few taps
Check the total — discount and VAT (if registered) are calculated for you
Share the PDF — by LINE, WhatsApp or email
Agreed → invoice — one tap gives you an invoice with the same items

Send the PDF by LINE

Tap Share on the document and send it as a PDF by LINE, WhatsApp, email or any app on your phone — with your logo on it.

Quote → invoice in one tap

Once the customer agrees, one tap turns the quote into an invoice with the same items, customer details and payment terms — no retyping.

Deposit and stage payments PRO

Add a deposit and up to 5 stage payments on one document, each with its own due date, and mark each stage paid as it comes in.

Automatic document numbers

Quotes and invoices are numbered in sequence automatically, and you can set your own number prefix.

VAT 7% on every plan

VAT-registered? The app calculates 7% VAT separately from the value and uses the tax-invoice heading. Not registered? You get a clean invoice without VAT.

Thai or English documents

Use the app in English and send documents in Thai, or the other way round — the document language is a separate setting.

PRO = included in the Pro plan

Common questions

Does a quotation need VAT?

Add VAT 7% only if you are VAT-registered; otherwise quote without VAT. A quotation is not a tax document — tax goes on the invoice or tax invoice when you bill.

How long should a quotation be valid?

It depends on your work — for example, how fast material prices move. What matters is stating the validity date clearly on the document, so the customer knows when to decide.

Is the form really free?

Yes — download it, print it and use it for your work. It is an A4 PDF in Thai, in the same design as the documents the GlideQuote app creates, for printing and filling in by hand; to type it and send it as a file, use the GlideQuote app.

How many quotations does the Free plan allow?

The Free plan allows 3 quotes a month; invoices and receipts are unlimited. Pro has no quote limit.

What does GlideQuote cost?

There is a permanent Free plan: unlimited invoices and receipts, 3 quotes a month, with a small GlideQuote watermark on PDFs. Pro on the Thai App Store is ฿166 a month billed annually (฿1,990 a year) or ฿299 month to month, and the first month is free.
