ABSTRACT
The term contract refers to a written or spoken agreement that is intended to be enforceable by law. The invoice is simply a document describing the work completed, the amount due, and the terms of payment. Invoices can be created via a number of different methods such as on a spreadsheet, in an app, online, or in a business software platform such as QuickBooks. Alternately, reader can print out the document and hand it directly to the client or even put it in the old-fashioned mailbox. Usually, however, a PDF as an email attachment is the best and most preferred method. Alternately, some apps and programs will allow reader to send a link to an online invoice viewing and payment system. Be sure to store copies of invoices on computer in an organized manner. While contracts, timesheets, and invoices are rather common, there are other documents that may be required by reader clients.
