Source Documents

Bookkeeping Basics
A source document is an original record which contains the detail that supports or substantiates a transaction recorded in an accounting system. The source document contains the details of a business transaction. A source document identifies 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 assigned a unique number, so that they can be identified and tracked in the accounting system. The pre-numbering of documents allows a company to determine whether any documents are missing.

Souce Documents can be internal as well as external documents.
