Six U.S. symbols are depicted in this primary source set: the Liberty Bell, the U.S. flag, the bald eagle, the national. anthem, Uncle Sam, and the Statue of Liberty. Historical Background.
Vouching is the essence or backbone of auditing because when performing an audit, an auditor must have proof of all transactions. Without the proof provided by vouching, the claims provided by the auditor are just that, only claims. In most cases, hard to detect frauds can only be discovered through the use of vouching.
Vouching refers to first selecting an item for testing from the accounting journals or ledgers and then examining the underlying source document. Thus, the direction of testing is from the journals or ledgers back to the source documents. Vouching provides evidence that items included in the accounting journals or ledgers have occurred (are valid).
