Free invoice generator

Create professional invoices in seconds

An invoice generator turns your work into a clear, professional request for payment. Instead of wrestling with a blank spreadsheet, you add your client, list what you did, and let it handle the numbering, the math and the layout, then send a polished PDF. Voila is built to do exactly that, and to keep every invoice safely backed up so you never lose one.

Whether you're sending your very first invoice as a freelancer or billing a client from a job site, the goal is the same: look professional, get the details right, and get paid faster.

How to make an invoice

Creating a professional invoice takes just a few steps:

1. Add your business details, name, address, phone and email, and your logo.
2. Add your client's details in the "Bill to" section.
3. Give the invoice a unique number and an issue date.
4. List each item or service with a description, rate and quantity.
5. Add any tax, discount or fees, and choose your currency.
6. Write your payment terms and instructions in the notes.
7. Review the total, then download the PDF or send it by email or text.

What to put on an invoice

Every professional invoice should include the same core elements:

• Header, the word "Invoice", so it's easy to tell apart from an estimate or receipt.
• Your business, name, logo, address, phone and email.
• Your client, their name and contact details.
• Invoice number and date, a unique number and the issue date.
• Line items, a description, rate and quantity for each good or service.
• Taxes and fees, tax, shipping or handling as separate lines.
• Balance due, the total amount the client owes.
• Payment terms, how and when to pay, and any late-payment terms.

How to send an invoice

Once your invoice is ready, send it by email or text, as a PDF attachment or a shareable link. With Voila you're notified when the invoice is viewed, so you know it landed, and overdue invoices are chased for you with automatic reminders.

Invoice generator vs a template

A Word or Excel template works for your first invoice, but by your third, you're duplicating files, re-typing the same client details and adding up totals by hand. An invoice generator saves your clients and items, numbers each invoice, does the math, and exports a clean PDF in one click. Prefer a file to start with? Grab one of our 20 free invoice templates.

Why use an invoice generator

• No re-typing, your clients and items are saved for next time.
• Automatic math, subtotals, tax and totals are calculated for you.
• Professional every time, a clean, consistent, branded layout.
• Share in seconds, download a PDF or send by email or text.
• Stay on top, see what's paid, unpaid or overdue at a glance.

Who uses an invoice generator

Freelancers, independent contractors and trades (plumbing, electrical, HVAC, handyman), consultants, photographers and other creatives, and small businesses all use an invoice generator to bill clients quickly and look professional, without an accounting department.

Create an invoice just by asking

Voila also lets you draft an invoice in plain language. Type something like "invoice Jane $400 for the kitchen sink repair" and it fills in the client, the line item and the amount for you to review. AI where it actually saves time, you're always in control before anything is sent.
