Free Invoice Generator
Fill in your business and client details, add your line items, and get a clean, professional invoice you can download as a PDF — free, with no sign-up. Everything is calculated for you and stays private in your browser.
What is the invoice generator?
An invoice generator is a free tool that helps you create a professional invoice and download it as a PDF without any software or sign-up. You enter your business details, your client's details and your line items, and it lays them out in a clean invoice and calculates the subtotal, tax and total for you. Slashit's invoice generator runs entirely in your browser, so the numbers and client information you enter are never uploaded to a server — they stay private on your device. It's built for freelancers, contractors and small businesses who need to bill a client quickly without paying for accounting software.
How our free invoice generator works
Enter your details
Add your business info, who you're billing, the invoice number and the dates. Pick your currency from the list.
Add your line items
List each item or service with a quantity and rate. The amount, subtotal, tax and total are calculated automatically as you type.
Download as PDF
Click Download PDF to open your browser's print dialog and save a clean, professional invoice — ready to send to your client.
What can you use the invoice generator for?
Billing your first freelance client
Getting paid needs a document with your details, the client's details, itemised work and a total — not accounting software and a subscription.
Invoicing occasionally alongside a job
For a handful of invoices a year, a monthly accounting tool is hard to justify. Fill in the fields and download a PDF when you need one.
Sending a one-off invoice while travelling
Nothing to install and no login means you can raise an invoice from any device with a browser.
Producing a clean copy for your records
A consistently formatted PDF per job makes bookkeeping and tax time considerably less painful.

Tips for getting the best results
Give every invoice a unique number
Sequential numbering is expected by accountants and is a legal requirement in many countries. Never reuse or skip numbers.
State payment terms explicitly
“Payment due within 14 days” with a specific date gets paid faster than leaving the timing unsaid.
Itemise clearly
One line per deliverable with quantity and rate prevents the queries and delays that a single lump sum invites.
Check your local tax rules
Whether you must show VAT, GST or a tax number varies by country and by whether you're registered. Confirm what your jurisdiction requires.
Keep a copy of every invoice
Download the PDF and file it. The tool doesn't store anything for you, by design.
Common problems and how to fix them
The totals look wrong
Check the quantity and rate on each line, and confirm whether tax should apply to the subtotal before or after any discount — the order changes the result.
My download saved as a web page instead of a PDF
In the print dialog, set the destination to “Save as PDF” rather than a printer. On mobile the option may be under a share menu.
My logo or details didn't carry over to the next invoice
Nothing is stored between visits, since everything stays in your browser. You'll re-enter your details each time.
