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.
