Why this one does not ask you to sign up
Most invoice generators send what you type to a server and build the PDF there. That means your client list, your rates and your tax number pass through somebody else’s machine, and there is usually an account attached to it.
This one assembles the PDF in the page you are looking at. Nothing is transmitted, there is nothing to sign up for, and you can disconnect from the network and it still works. Your draft is kept in this browser so a closed tab does not lose it — and only in this browser, so a different computer starts blank.
How the totals are worked out
In order: each line is quantity times rate, rounded to the cent. Those rounded amounts are what the subtotal adds up, so the column on the page always sums to the figure printed under it.
Then the discount comes off the subtotal, tax is charged on what remains, and shipping is added afterwards — shipping is not taxed. Anything already paid is subtracted at the end to give the balance due. If your jurisdiction taxes shipping or applies tax before discounts, put the figure in as an amount rather than a percentage.
Every sum is done in whole cents rather than in decimal fractions. It sounds pedantic until an invoice arrives whose lines add up to a penny less than its total, which is exactly what floating-point arithmetic produces.
Long invoices
The layout is worked out before anything is drawn, so a thirty-line invoice breaks across pages properly: the table header repeats, rows are never split in half, and the totals block stays with the last line rather than being pushed off the bottom of the page. Pages are numbered once there is more than one.
Frequently asked questions
Is my invoice uploaded anywhere?
No. The PDF is assembled by JavaScript on your own machine and saved straight to your downloads folder. No account, no server, nothing to delete afterwards.
Where is my draft saved?
In this browser’s local storage, on this device only. Clearing site data or opening the tool on another computer gives you a blank invoice. Your logo is not kept — a large image would fill the storage quota and take the text with it.
Can I send the invoice from here?
No — sending needs a server, and adding one would mean your invoices passing through it. Download the PDF and attach it to your own email.
Is this a legally valid invoice?
It produces a normal PDF invoice with the fields most jurisdictions expect. What has to appear on it — tax numbers, registration details, particular wording — varies by country and by what you sell, so check your local requirements. The tool lays out what you give it; it does not know your tax rules.
Can I save a template for next time?
The draft persists, so your own details and settings are still there when you come back. Change the number and the line items and download again.
