# We built a free invoice maker for Japan and Singapore. Here is how it works > Denpyo now has a free invoice maker. Make a Japanese qualified invoice with withholding tax, or a Singapore GST tax invoice, and download the PDF without an account. A step-by-step walkthrough from the Denpyo team. - URL: https://denpyo.com/en/blog/free-invoice-maker - Published: 2026-11-12 - Language: en We're the team behind Denpyo. Denpyo started in Japan as an app for keeping receipts and getting your books ready for an accountant. This week we added the other half of that job: a [free invoice maker](https://denpyo.com/en/tools/invoice-maker?ref=blog_launch). You can make an invoice and download the PDF without creating an account. This post explains why we built it, what it does, how to use it step by step, and what it does not do. ## Why we built it Until now Denpyo dealt with money going out: receipts, expenses, the pile you hand to your accountant. But a freelancer's work does not stop there. You do the work, you send an invoice, and then you wait to be paid. If the receipts live in one place and the invoices in a spreadsheet, you still spend the end of every month moving between the two. What makes invoicing slow is the rules, not the typing. In Japan a client may need a qualified invoice (適格請求書) with your registration number and the tax shown for each rate, and many freelance fees have income tax withheld, so the amount that arrives differs from the amount you billed. In Singapore a GST-registered business has to issue a tax invoice with particular fields. We wanted a tool that knows these rules, so you do not have to look them up every time you bill someone. ## What it does - **Works without an account.** Open the page, fill in the invoice and download the PDF. Without an account you get three PDF downloads a day. - **Japan.** Enter your registration number (T and 13 digits) and the invoice carries the six items a qualified invoice needs. Consumption tax is worked out once for each rate, 10% and 8%. Withholding tax is optional: 10.21%, and 20.42% on the part above ¥1,000,000. - **Singapore.** Enter your GST registration number and the document is titled Tax Invoice, with GST at 9% and the totals before and after GST shown separately. Your PayNow details and bank account go on it. If you are not GST-registered, no GST is added. - **Hong Kong and Malaysia.** A Business Registration number and FPS details for Hong Kong, with no tax line. SST at 8% or 6% and DuitNow details for Malaysia. - **Four documents.** Invoice, quote, delivery note and receipt. - **Two languages at once.** The app comes in eight languages and the document's language is set separately. You can work in English and send a Japanese invoice. - **With a free account:** save your invoices, send each one as a link or by email, see when your client opens it, and keep track of what is unpaid, overdue and paid. ## How to use it *The invoice maker in about fifteen seconds.* *If the video does not play: it shows an invoice being filled in, the tax appearing on the page, the PDF being downloaded, and the invoice being sent to a client as a link.* ### 1. Fill in the invoice. No account needed Open the [invoice maker](https://denpyo.com/en/tools/invoice-maker?ref=blog_launch), pick your country at the top of the page, and choose "Make an invoice, free". You can also type a client, an item and an amount into "Try it with your own invoice" further down the page; what you type comes with you into the editor. In the editor, the left side has five cards: From, Bill to, Items, Tax and Payment. The right side is the invoice itself, and it changes as you type. In the screenshot the app is in English and the invoice is in Japanese. The two are set separately at the top, next to the document type and the country. ![The invoice editor in English, with a finished Japanese invoice on the right](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/02-editor-filled-invoice.webp) *The editor. Your details on the left, the invoice on the right.* ### 2. Let it work out the tax You enter prices before tax and mark each line 10% or 8%. The invoice adds up each rate separately and works out the tax once per rate, which is what the qualified invoice rules ask for. Tax is rounded down by default, and you can change that. Switch on withholding tax in the Tax card if your client withholds. In this sample the total with tax is ¥408,960, ¥36,756 is withheld, and the amount the client will transfer is ¥372,204. The invoice shows all three, so nobody has to do the subtraction. ![A Japanese invoice showing tax at 10% and 8%, the withholding tax, and the amount due after withholding](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/03-invoice-paper-tax.webp) *Tax for each rate, the withholding, and what the client actually pays.* ![A Singapore tax invoice in SGD with a GST registration number, 9% GST and PayNow details](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/13-invoice-paper-sg.webp) *The same tool on the Singapore page: a tax invoice with 9% GST and PayNow details.* ### 3. Download the PDF Choose Download PDF. If you have not entered your name or business name yet, it asks for that first, because an invoice needs to say who it is from. You still do not need an account. The file is made in your browser and saved to your computer or phone. If all you want is an invoice to attach to an email, you can stop here. ![The downloaded PDF: a one-page Japanese invoice](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/05-downloaded-pdf-page-v2.webp) *The PDF. A small "Made with Denpyo" credit sits at the bottom.* ### 4. Create a free account to save and share Until you sign up, your invoice is saved only in the browser you made it in. When you want to keep it or send it as a link, create a free account with Google, Apple, LINE or an email link. The invoice you were working on comes with you. Before you send, Preview shows the page your client will see, on a computer and on a phone. ![A preview of the client's page: the invoice on the left, the amount due and bank details on the right](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/06-client-view-preview.webp) *Preview: what your client will see.* ### 5. Send it by link, or let Denpyo email it Sharing gives the invoice its own link. Send it the way you already talk to that client: LINE, WhatsApp or your own mail app. Or copy the link and paste it anywhere. Or choose "Email it for me". You type the client's address and an optional note, and Denpyo sends an email with the link and the PDF attached. It goes out under your name (shown as sent via Denpyo), and when the client replies, the reply comes to you. ![The dialog shown after sharing, with the link and buttons for LINE, WhatsApp and the mail app](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/07-share-ready-to-send.webp) *After sharing: one link, sent however you like.* ![The share panel with Email it for me open: the client's email, an optional message, and Attach the PDF](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/08-email-it-for-me.webp) *"Email it for me": the PDF is attached unless you switch it off.* ### 6. See when your client opens it Your client opens the link on any phone or computer. They see the invoice and the amount due, can copy your bank details, and can save the PDF. The page tells them that you will be told it was viewed. When they open it, you get an email and a notice in the app. In your list of invoices the status changes from "Not opened yet" to "Opened". If you use Denpyo in a company or accounting-firm workspace, the list is there too, under "My invoices". ![The page a client sees: the invoice, the amount due, bank details with Copy buttons, and Save PDF](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/09-client-page.webp) *The client's page.* ![The invoices list with totals for unpaid and overdue, and each invoice's status](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/10-invoices-list.webp) *Your invoices: not opened yet, opened twice, overdue, paid.* ### 7. Mark it paid When the money arrives in your bank account, open the invoice's menu and choose Mark as paid. Denpyo does not see your bank account, so this step is yours. The same menu duplicates an invoice for next month, turns the link off, or voids it. ![The menu for one invoice, with Mark as paid, Download PDF, Duplicate and Turn off link](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/11-mark-as-paid.webp) *Mark as paid, from the invoice's menu.* ### 8. Quotes, delivery notes and receipts The document type at the top left switches between invoice, quote, delivery note and receipt. Each keeps its own numbering. ![The document type menu listing invoice, quote, delivery note and receipt](https://api.denpyo.com/storage/v1/object/public/blog-images/content/free-invoice-maker/en/04-document-types.webp) *Four document types.* ## What it does not do You should know these before you rely on it. - **It does not collect money.** You put your own bank details, or your own payment link, on the invoice. You mark an invoice paid yourself. - **It does not check registration numbers against the National Tax Agency's registry.** It checks that the number has the right format and, for corporate numbers, the right check digit. Look your own number up on the NTA site. - **It does not decide whether withholding applies to your work.** It does the arithmetic once you switch it on. - **It is not an e-invoicing system.** It does not send through InvoiceNow in Singapore or MyInvois in Malaysia. - **Without an account** you get three PDF downloads a day, and the draft stays in that browser. - **Logos.** To show company logos, it looks up the business names and websites you type. - **It is not tax advice.** For a question about your own situation, ask a tax accountant. ## Why it is free Making invoices, downloading PDFs, saving them and sharing them cost nothing. The invoice maker is an entry point to Denpyo: if it is useful, some people will try the receipts and bookkeeping side too. That is the whole reason. ## What is next We will fix what people report first. If a client sends your invoice back because something is missing, or the tax handling is wrong for your case, [tell us](https://denpyo.com/en/contact). We read everything.
