An invoice with all of the necessary elements may be easily created using one of the convenient and free invoice templates online. Invoice types may include an invoice for a particular service, labor and materials invoice, proforma invoice, among others. Free templates are generally available in a variety of formats you probably already have on your computer, such as HTML, Microsoft Word, Microsoft Excel, or PDF. Some free templates include time-saving features, like self-calculation for easy figuring, generic logos or options to add your own logo, automatic date stamping, and easy drop down menus for selecting items or services to customize your invoice.
