About this tool
Create quotations, invoices, receipts and tax invoices in a couple of minutes: fill in one screen and print straight to a PDF you can email. Nothing to install, no account, and no watermark on the document.
Built for freelancers, online sellers and small businesses that aren't ready to pay monthly for accounting software but still need paperwork that looks professional — especially when a corporate client wants a quotation before approving, or a receipt to file an expense claim.
The calculation order is the part most tools get wrong:
- Line items are summed into a pre-discount subtotal
- The discount comes off — as a fixed amount or a percentage
- VAT (7%) is charged on the base after the discount, not before
- Withholding tax is taken from the pre-VAT base, and the net payable shows what the client will actually transfer
- The total is spelled out as a Thai amount in words, automatically
Details that make repeat use fast: your own details are remembered on this device, so next time you only fill in the customer and the lines · set your own document number prefix and running number · toggle the signature lines · add notes such as bank details or payment terms.
Privacy is the clear difference. Customer names, amounts and tax IDs are never uploaded: the document is built in your browser and printed from your machine. The only thing stored is your own seller information, in this browser, and only if you ask for it.

Frequently asked questions
- Is it really free? Do I need an account?
- Completely free, no sign-up, no limit on how many documents you make, and no watermark or our logo on the printed result.
- Where does my customer data go?
- Nowhere. The document is assembled in your browser and printed from your own device. Only your own seller details are stored, in this browser's localStorage, when you choose to save them — no customer name or amount is ever uploaded.
- Why print instead of downloading a PDF directly?
- Printing through the browser gives the best Thai typography, keeps the text selectable and searchable in the saved file, and needs no embedded font. When the print dialog opens, choose "Save as PDF" and you get the same file a download would give you.
- Which amount is withholding tax based on?
- Always the pre-VAT amount. The discount comes off first, VAT is charged on what remains, and withholding tax is taken from that same base. Net payable is the grand total minus the withholding tax.
- Can I use the tax invoice for filing?
- This is a helper template, not a Revenue Department-certified form. If you issue a tax invoice so your customer can claim input tax, check that everything the law requires is present — the words "ใบกำกับภาษี", tax IDs, and a sequential document number.
- Does it write the amount in words?
- Yes. The grand total is spelled out in Thai — e.g. หนึ่งหมื่นเจ็ดร้อยบาทถ้วน — and printed on the document, following the standard Thai reading rules.
