About InvoicesAndReceipts.com

InvoicesAndReceipts.com makes three business documents and hands you a PDF: an invoice, which asks for money and ends with a balance due; a receipt, which confirms money already arrived and ends with an amount paid; and a quote, which prices work not yet agreed and ends with a quote total. There is no account to create, no watermark, and no paid tier. You fill in the form, the document is drawn in your browser, and you download it.

Three documents, one line that matters

The three are nearly the same page of paper, and the bottom line is where they differ. That is not a cosmetic distinction: a receipt reading “balance due” invites your customer to pay a second time, and a quote reading “balance due” demands money that is not owed yet. So the wording changes with the document type rather than leaving you to relabel a total by hand — the kind of edit that is easy to forget when a receipt started life as a copy of an invoice.

Who actually uses this

Sole traders and freelancers billing a handful of clients a month. Tradespeople who need to hand over a receipt on the spot for a cash job, where the receipt is the only record either side will ever have. Small sellers issuing proof of payment. Anyone who has to put a price in writing before starting work. What these situations share is a volume too low to justify accounting software with a subscription and a login, and a document that still has to be right, because the person receiving it will check it against their own arithmetic.

Why the arithmetic is done the way it is

Every amount is held as an integer number of cents rather than a decimal, because binary floating point cannot represent a value like 0.1 exactly and the error accumulates down a long column. Each line is rounded once, half away from zero, so the printed lines reconcile with the printed subtotal. Discount comes off before tax, because tax is owed on what was actually charged. Shipping is added after tax, which is a documented simplification. Tax marked as already included is extracted by dividing by one plus the rate, never by subtracting a percentage — subtracting overstates the tax by a fifth, and it is the most common arithmetic error on hand-made invoices.

The money engine is covered by an automated test suite checked against figures worked out by hand, and the worked examples on the methodology page are computed at build time by that same engine, so the prose there cannot drift from the tool. The limits are written down on the same page: up to 200 lines, quantities held to four decimal places, a discount that can reduce a document to zero but never below it, and ten currency symbols that label a document without converting anything.

Why nothing leaves your device

An invoice carries your client list, your rates, and what you charged. None of it is uploaded. The pages are static files, and the PDF is assembled and drawn on your own machine — there is no server to send your typing to and no database that could leak it. That is a property of the architecture rather than a promise about our conduct, which is the only version of this claim worth anything. The other side of the same fact: nothing is stored, so closing the tab discards the document. Download the PDF before you do.

What it is not

A document generator, not an accounting system and not tax advice. It does not file anything, track whether you were paid, chase late payers, apply per-jurisdiction tax rules, validate tax numbers, convert currencies, or number your documents sequentially across sessions. If you need recurring billing or bookkeeping, you need software with an account, and this is deliberately not that.

Found something off?

A total that disagrees with your own calculator is the report we most want, because each one either uncovers a real bug or reveals a convention worth documenting. The contact page explains what to include so the figure can be reproduced. The site is published by Sumvia, the team behind the Sumvia.net tool network.
