About Onigiri Invoice Generator
Start an invoice from any tab. Onigiri Invoice Generator opens in Chrome's side panel, keeps your business and client details handy, and takes you to Onigiri's free invoice generator to finish the invoice and download a PDF. Free, no sign-up, no watermark.
HOW IT WORKS
1. Click the Onigiri icon in your toolbar. The side panel opens next to the page you're on.
2. Add your logo, your name or business, email and address, and the same for your client.
3. Click Generate Invoice. onigiri.one/invoice-generator opens with everything filled in.
4. Add line items, tax, discounts, payment details and notes, then download the PDF.
WHAT YOU GET
- Your logo and details on a clean, professional invoice
- Line items with quantity, rate and an optional description; totals update as you type
- Tax, discounts and custom lines, in the currency you pick
- Full-screen preview, then a PDF download with no watermark
• Your details stay saved in the side panel for the next invoice
PRIVATE BY DESIGN
The extension keeps what you type on your device and passes it only to the Onigiri invoice generator page you open. It makes no network requests of its own, and you don't need an account.
WHO IT'S FOR
Freelancers and small business owners who bill clients and want a good-looking invoice fast.
NEED MORE THAN A PDF?
Onigiri is stupidly simple invoicing for freelancers and small businesses. With a free Onigiri account you can send invoices as a link your clients open on any device, see which ones are paid, sent or overdue, and accept card payments via a link through your own Stripe account with a 0% platform fee. Made by a small indie team, without venture backing.
