The Invoice & Quote Generator
Fill in the form and watch the document take shape next to it. Print it to PDF when it is ready. Nothing is uploaded and no watermark is added.
1 · The document
2 · Your details
3 · The client
4 · What you are charging for
5 · Discount and tax
The label and the rate are yours to set: VAT, GST, sales tax or none at all. Turn on a rate per line for a mixed-rate document, and the totals will show one row per rate. If you need to look a rate up, the VAT calculator carries the 2026 rates for six countries.
6 · Notes and payment details
The draft is kept in this browser so it survives a reload. Save it as a file to keep it or to move it to another device.
Saved documents
Documents you save are kept in this browser and nowhere else. They are never uploaded, and clearing your browser data removes them, so keep anything important as a file too.
Design
The design is saved with the draft, so a document reopens looking exactly as you sent it. The preview is the page that prints: what you see is the paper.
Ready-made documents

- Save the document to this browser if you will want it again, and save the client so you never type them twice.
Frequently asked questions
Is the invoice watermarked or limited?
No. The document is yours, with no watermark, no logo of ours and no limit on how many you make.
Can I use it for quotes and estimates?
Yes. Switch the document type to Quote and the heading, the numbering prefix and the date label change with it.
Can I change how the invoice looks?
Yes. Pick one of eight templates, set the accent color to your brand's, choose a font pairing and print on A4 or US Letter. The preview is the page itself, and the design is saved with the draft, so every document you send looks the same.
Where is my draft kept?
In this browser's local storage, so it is still there when you come back. Use Save the draft to keep a copy as a JSON file, and Load a draft to bring it back or move it to another device.
Is the invoice legally valid?
The layout carries what most countries expect: who is invoicing whom, a number, dates, the items, the tax line and the total. What your country requires beyond that (tax IDs, wording, numbering rules) is your responsibility; FinKit gives no tax or legal advice.
Can I add several tax rates?
Not yet: the document has one tax line, with a label and a rate you choose. Per-line rates are on the list for a future version.
Can I keep the invoices I have made?
Yes. Save a finished document and it joins a list in this browser, with its number, its client and its total, and you can open it again or duplicate it into the next invoice for the same client. It is stored in your browser only, so it is not visible to us and it goes when you clear your browsing data. Anything that matters should also be saved as a file, which the save button does.
Do I have to retype a client every time?
No. Save a client once and they go into a list on this page, with their address, email and tax number. Choosing them again fills the document in. Like everything else here the list is kept in your own browser, so a client's details never reach a server.
