Free Invoice Generator

Example Calculation

A consultant bills 10 hours at $95 an hour and a $250 project setup fee. The subtotal is $950 + $250 = $1,200. Take off a $100 discount and add 6% sales tax on the $1,100 that is left ($66.00), and the invoice total is $1,166.00.

Put a clear invoice number, issue date, due date (for example "Net 30") and payment instructions on the invoice, and keep a copy for your records.

How It Works

A clear invoice helps you get paid faster and keeps your bookkeeping tidy. This free invoice generator lets you fill in your business details, your client’s information, an invoice number, dates and as many line items as you need. The invoice preview on the right updates live as you type, so you always see exactly what your client will receive.

Each line item has a description, a quantity and a rate. The tool multiplies quantity by rate, adds up the subtotal, applies an optional dollar discount, and then adds sales tax if you enter a percentage. The total due is shown in US dollars at the bottom, with your notes and payment terms underneath. Everything is calculated in your browser, so none of your business or client data is uploaded to a server.

When you are happy with the invoice, choose Print / Save as PDF. Your browser’s print dialog opens, and you can either print on paper or select “Save as PDF” as the destination. You can also download the invoice as an HTML file to keep a copy or email. For recurring work, simply change the invoice number and dates and reuse the same details.

A professional invoice normally includes: your business name and contact details, the client’s name and address, a unique invoice number, the issue date, the due date, a clear description of products or services, the amount due, accepted payment methods and late-fee terms if any. Keep records of invoices you send for at least as long as the IRS recommends for your tax records, and check your state’s rules for whether you need to charge sales tax on your services.

Formula Explained

Line amount = quantity × rate

Subtotal = Σ line amounts; Tax = (subtotal − discount) × tax %; Total due = subtotal − discount + tax.

Assumptions and limits

• The invoice is created and kept in your browser. It is not uploaded or stored on a server, and it is gone when you close the page unless you save it.
• The tax is a single percentage applied to the amount after the discount. Sales tax, VAT or withholding rules differ by place and by what you sell.
• It is a template, not legal, accounting or tax advice. Check the rules for invoices where you do business.
