Invoice generators can speed up the process of creating and sending out invoices. An invoice is often requested by a client before they make a payment, but even if they don’t ask for one, you could send them one anyways to demonstrate your professionalism.

What Are Invoice Generators?

Invoice generators are online tools that allow you to create invoices within your web browser. They follow a template to ensure you don’t forget to include important details when filling out your invoices. They are not like invoicing/time-tracking apps like FreshBooks or Zoho Invoicing because invoice generators are single-purposed: They simply help you create an invoice and do not have any advanced features like time-tracking, financial accounting, and team collaboration.

Think of invoice generators as Internet-enabled alternatives to desktop-software invoice templates that are commonly used in Microsoft Word, Adobe Acrobat or other desktop publishing software.
