Free Purchase Order Generator (South Korea)

Questions people ask

Is this free?

Yes. Every document is free, with no watermark and no account. The PDF is built in your browser and nothing you type is sent to a server.

Should I charge VAT on my document?

Only if your business is registered for VAT with National Tax Service (NTS) and the supply is taxable. The standard rate in South Korea is 10%. If you are not registered, leave the toggle off and the document states that no VAT was charged.

Which document do I need?

A quotation before the work to agree a price; a proforma to ask for a deposit; a purchase order when you are the one buying; a waybill to travel with goods; an invoice when the work is done; a credit note to reduce an invoice already sent.

Is a PDF from this site a legally valid tax invoice in South Korea?

It carries the fields a tax invoice needs, including the Business registration number. Where South Korea requires invoices to be issued or validated through an official electronic system, the PDF is a working document and the official system issues the fiscal one. Check the rules that apply to your registration.

Can I send it on WhatsApp?

Yes. Download the PDF, then use Share on WhatsApp. It opens a chat with the summary already written, and you attach the file.

Can I change the document after I download it?

The PDF is finished, but your details stay on this device, so making a corrected one takes seconds. Recent documents are listed beside the form and reopen with everything filled in.

How should I number my documents?

In one unbroken sequence, with no gaps and no number ever reused. A year prefix helps, for example 2026-001. National Tax Service (NTS) checks sequence, and a missing number invites the question of what was on it.

My client says the amount is wrong. Do I edit the invoice?

No. Leave the original as issued and raise a credit note that references its number, states the reason and reverses the VAT. Editing a sent invoice leaves you with two documents bearing the same number and no way to explain the difference.

Can I bill a client in another country?

Yes. Change the currency on the document and it prints with the ISO code, so nobody has to guess which dollar you mean. Whether you charge VAT on an export is a separate question for National Tax Service (NTS); many exports are zero-rated or outside the scope.
