What is a Source Document?

A source document is the original document that contains the details of a business transaction. A source document captures the key information about a transaction, such as the names of the parties involved, amounts paid (if any), the date, and the substance of the transaction. Source documents are frequently identified with a unique number, so that they can be differentiated in the accounting system. The pre-numbering of documents is particularly useful, since it allows a company to investigate whether any documents are missing.
