Invoice & Receipt Generator

How to use

Pick whether you're creating an invoice (a request for payment) or a receipt (proof that payment was received), then fill in your details. Add a line for each product or service with its quantity and unit price — the amount and running totals update as you type.

Everything else is optional. Choose a payment term such as Net 14 and the due date fills in for you. Apply one tax rate to the whole invoice, or switch on Different tax rate per line when items are taxed differently. Take a discount as a percentage or a fixed amount, add shipping, and record any amount already paid to show a running balance due. Upload a logo and a signature image, pick one of three PDF themes, then click Download PDF.

If you invoice the same client regularly, Save draft keeps a named copy — logo and signature included — in this browser so you can reopen it and change only the numbers. The whole document is assembled in your browser, so it's instant and completely private.

Is there a watermark, a sign-up, or a paid tier?

No to all three. The PDF you download carries your business name, your logo and your details — nothing of ours. No watermark, no "Created with…" footer, no stamp across the page, and no branding that reappears the moment you send it to a client. There is no account to create, no email address to hand over, no free-trial counter that stops you at three invoices, and no upgrade prompt hiding behind the download button.

It's worth explaining why, because "free invoice generator" usually isn't. Most free tools in this category are the front door to an accounting subscription: the watermark exists to make the free tier slightly embarrassing to use in front of a paying client, so you upgrade. That business model needs your email, which is why it needs an account. Ours doesn't exist, because the invoice is assembled by your own browser — there is no server rendering PDFs, so there is no per-invoice cost for us to recover. The page is funded by advertising, and that's the entire arrangement.

The practical upshot: what you see in the preview is exactly what your client receives, you can generate fifty invoices in an afternoon, and the documents are yours to use commercially without attribution or a licence.

What makes a complete invoice

A professional invoice does more than state an amount — it gives your client everything they need to pay you quickly and to file the document correctly. At minimum, include:

• Who you are. Your business name, address, and a contact email in the From block. If you're registered for tax, add your registration number here.
• Who it's for. The client's name and details in the Bill To block, so there's no ambiguity about who owes what.
• A unique number. Sequential numbers (INV-001, INV-002…) make invoices easy to reference and are expected by most accounting systems and tax authorities.
• An itemized list. A clear description, quantity, and unit price for each line means fewer payment questions and disputes.
• Clear totals. Subtotal, any discount, tax, and the final amount due, shown separately so the math is transparent.
• Payment terms. When and how you expect to be paid. Choose a term such as Net 14 or Net 30 and the due date is calculated for you — both appear in the PDF header. Put the practical details, like your bank account or payment link, in the notes field.

How the totals are calculated

Each line amount is quantity × unit price, rounded to two decimal places. The subtotal is the sum of those line amounts. A discount is applied to the subtotal first, tax is charged on the discounted (taxable) amount, shipping is added after tax, and anything you've already been paid comes off last:

balance due = (subtotal − discount) + tax + shipping − amount paid

A few details worth knowing. A fixed discount larger than the discountable subtotal is capped at that subtotal, so a total never goes negative. Shipping is added after tax and is not itself taxed. If you untick Discount on a line, that line is excluded from the discount base and marked with an asterisk in the PDF, with a footnote explaining why. In per-line tax mode the discount is spread across the discountable lines in proportion to their amounts, so each line is taxed on what it actually cost after the discount.

Rounding happens at each boundary — per line and on each total — which avoids the small "off by a cent" drift you get when fractional amounts accumulate. Negative rates are treated as zero, so a stray minus sign never inflates a total.

Worked example

Say you bill a client for 10 hours of design at £50.00 and a one-off £120.00 hosting setup. The two lines come to £500.00 and £120.00, a subtotal of £620.00. Apply a 10% loyalty discount (−£62.00) and the taxable amount is £558.00. At a 20% VAT rate, tax is £111.60, so the total due is £669.60. If the client already paid a £200.00 deposit, enter it as the amount paid and the invoice shows a balance due of £469.60. Switch the document type to Receipt once they settle the rest, keep the same numbers, and you have a matching proof-of-payment PDF.

Tips and common mistakes

• Number every invoice. Gaps or duplicates cause reconciliation headaches at tax time. Keep them sequential.
• State payment terms explicitly. "Due on receipt" and "Net 30" set very different expectations. Say which, and name the accepted payment methods.
• Check your tax rate. Sales tax, VAT, and GST rules vary by region and by what you're selling. Use one rate for the whole invoice, or switch on per-line tax when items are taxed differently — either way, confirm the rates are the right ones.
• Keep a copy. Saved drafts live in this browser only and disappear if you clear your site data, so they're a convenience, not an archive. Save the PDF (and send yourself a copy) so you have a permanent record.
• Make a printed invoice payable. If the invoice will be handed over on paper, a typed-out payment URL is a transcription error waiting to happen. Generate a QR code for your payment link, download it as a PNG, and attach it in the signature image slot — the client scans it instead of retyping it.
• The total isn't what you keep. If you invoice as a freelancer, tax on your profits comes out of these amounts later. Worth running the year's expected billings through the salary & take-home pay calculator as a rough guide, so the tax bill isn't a surprise.

Because the calculation logic is the same code that renders the PDF, the figures you see on screen always match the downloaded document — there's no separate export path to drift out of sync.
