Send invoices that get you paid, without the software
Every freelancer and small business hits the same wall: the work is done, the client is happy, and then the admin drags on for weeks. Professional invoicing software costs money, locks your client list inside someone else’s account, and usually wants your email before you can even download your own document.
LancerBill’s invoice generator takes a different route. Everything runs in your browser. Type in your business details, your client’s details, line items, taxes and discounts, and download a clean, professional PDF. Nothing is uploaded to a server, no account is created, and there is no email gate standing between you and your invoice.
This tool is built for freelancers, contractors, consultants, tradespeople and small businesses that send invoices anywhere in the world. It supports over 100 currencies with correct local formatting, per-country tax presets (VAT, GST, sales tax) so your invoice shows the right tax treatment, and sequential invoice numbering that keeps your records tidy.
Your data never leaves your browser. The PDF is generated on your device - no account or signup needed.
How to use it
- Enter your business details: name, address, email and phone. Add your logo if you have one.
- Enter your client’s details: name or company, billing address and contact email.
- Set the invoice number (a fresh sequential number is suggested automatically, e.g. INV-2026-001), the invoice date and the payment due date.
- Add line items: a description of the work, quantity, unit price and unit (hours, days, items). Discounts and taxes can be applied per line or on the whole invoice.
- Select your country to apply its standard tax preset (UK VAT, Australian GST, Singapore GST, US sales tax base rates and more) or enter a custom rate.
- Review the live totals, then download the invoice as a PDF. For repeat clients you can save the client to your local client book so the next invoice takes seconds.
What it calculates and how the totals work
The generator applies standard invoice arithmetic, and every figure is shown on the document so there are no surprises:
| Line | Formula |
|---|---|
| Line total | Quantity × unit price − line discount |
| Subtotal | Sum of all line totals |
| Discount (invoice-level) | Percentage or flat amount off the subtotal |
| Tax | Rate × (subtotal − discount) |
| Total due | Subtotal − discount + tax + shipping/fees |
Assumptions the tool makes, stated openly:
- Tax is applied once, after discounts, unless you set a per-line tax. This matches how most small businesses invoice; it is not a substitute for your jurisdiction’s exact rules on discount treatment.
- Per-country presets apply the country’s standard rate only. Reduced, zero or exempt rates are your responsibility to select when they apply (the custom-rate field exists for exactly this reason).
- Shipping and extra fees are added after tax by default, since most delivery charges are quoted tax-inclusive or billed separately. Adjust as your local rules require.
The tool also generates invoice numbers in a sequential scheme (INV-2026-001, INV-2026-002…) and remembers the last number in your browser so you never reuse one. Keep them sequential and unbroken: tax authorities in many countries expect it.
Worked example: freelance web developer invoice
Maya, a freelance web developer in Manchester, finishes a project for a local agency. She enters:
- Business: Maya Owen Web Design, her address, hello@mayaowen.dev
- Client: Northern Retail Ltd, Manchester, accounts@northernretail.example
- Line 1: “Homepage redesign”, 1 × £1,800.00
- Line 2: “Ongoing maintenance, March”, 10 × £65.00 = £650.00
- Invoice number: INV-2026-014, dated 4 October 2026, due 4 November 2026 (30-day terms)
- Country preset: United Kingdom → VAT 20% applied to the subtotal of £2,450.00 = £490.00
- Total due: £2,940.00
The PDF shows her business details at the top, the itemised lines, the VAT line, the total in bold and the payment terms at the bottom. Maya sends it the same morning she finished the work — the single biggest factor in getting paid quickly is invoicing quickly.
Important considerations and limitations
- Invoices have legal requirements that vary by country. In the UK, a VAT invoice must show a VAT number, VAT rate per item and the VAT amount (see GOV.UK’s invoicing rules linked below). In Australia, a tax invoice over A$1,000 needs your ABN and the buyer’s identity. The generator provides the fields; you are responsible for completing them correctly for your jurisdiction.
- This is a document generator, not accounting software. It does not track payments, chase overdue invoices, reconcile your bank or file your taxes. For a free chasing workflow, pair it with the late payment fee calculator once an invoice goes overdue.
- Sequential, unbroken numbering matters. Deleting or skipping numbers can cause problems in an audit. If you make a mistake, issue a credit note rather than deleting the invoice.
- Keep your own records. Your browser can save a local copy history, but browsers get reset. Back up important invoices as files in your own storage — the “export/import” option exists so you can move your client book between devices yourself.
- Browser-local means privacy, with one trade-off: because nothing leaves your device, nothing is synced automatically. That is the point, but treat your browser storage accordingly.
Frequently asked questions
Is the invoice generator really free?
Yes. There is no account, no trial, no email capture and no invoice limit. The tool runs entirely in your browser, so there is nothing for us to charge a subscription for.
Is my client data uploaded to your servers?
No. All processing happens locally in your browser. Your business details, client details and invoice contents are never sent to us or to any third party. If you delete your browser data, your locally stored invoices go with it — which is why backing up important ones matters.
Can I add VAT, GST or sales tax?
Yes. Select your country and the tool applies the standard preset (for example UK VAT at 20%, Australian GST at 10%, Singapore GST at 9%). You can always override the rate manually, which you should do whenever reduced or zero rates apply.
Can I download the invoice as a PDF?
Yes. The download button produces a print-ready PDF you can email or message to your client. It looks professional without any branding from us — your business is the brand on the page.
What invoice number should I use?
Use a simple sequential scheme and never reuse a number. The tool suggests the next number automatically (INV-2026-001, and so on). Many tax authorities expect unbroken sequences, so do not skip or delete numbers.
Can I save repeat clients?
Yes, your browser keeps a local client book. Enter a client once and selecting them on the next invoice fills everything in. You can export this data to a file and import it on another device.
How is this different from the quote generator?
A quote is a price you offer before the work starts; an invoice is a demand for payment after the work is done (or at an agreed milestone). The natural workflow is: send a quote, get approval, do the work, convert it to an invoice, and when it is paid, issue a receipt. All three tools live on this site and follow that sequence.
Do I need a registered business to invoice?
In most countries, no — sole traders and freelancers can invoice in their own name. You may need a tax ID (such as a VAT number or ABN) once you cross registration thresholds or charge tax. Check your local rules if you are unsure.
