What is the Simple Invoice Generator?
The Simple Invoice Generator is a free online tool that lets freelancers, small businesses, and contractors create a clean, professional invoice without opening a spreadsheet, design tool, or dedicated accounting software. You fill in your business details, your client's details, an invoice number and date, one or more line items describing the work or products provided, and an optional tax rate — the tool then lays everything out on a properly formatted invoice and generates a ready-to-send PDF you can download instantly. This is especially useful for freelancers and small operators who need to bill clients regularly but don't want the overhead or monthly cost of a full invoicing platform, as well as anyone who just needs a one-off invoice for a single project or sale. The generated PDF includes your business and client information, an itemized table of quantities and unit prices, a computed subtotal, tax amount, and grand total, plus space for any additional notes such as payment instructions or terms. Because the totals are calculated automatically from your line items and tax rate, there's no risk of manual arithmetic errors creeping into the amount a client is billed. The tool doesn't store your invoice data after you download the PDF, so it's suitable for quickly generating invoices containing sensitive client or pricing information.
How to use it
Start by entering your business name and address, followed by your client's name and address. Fill in an invoice number, the invoice date, and an optional due date. Add each item, service, or product you're billing for as a separate line item with a description, quantity, and unit price — the subtotal for each line and the running total update automatically as you type. If applicable, set a tax rate as a percentage, which the tool will apply to the subtotal to calculate the tax amount and final total. Add any notes you want included on the invoice, such as payment terms, bank details, or a thank-you message. Once everything looks correct, click 'Generate invoice PDF' and then 'Download PDF' to save the finished invoice to your device, ready to attach to an email or print. You can generate as many invoices as you need by simply changing the details and clicking generate again for each new client or project.
