Final answer:
Ledgers are not a source document; they are records that summarize and classify transactions from source documents.
Step-by-step explanation:
The source document in accounting is the original record containing the details to substantiate a transaction entered in an accounting system. The following are examples of source documents:
- Purchase orders
- Bank statements
- Sales receipts
- Bills from suppliers
Ledgers, on the other hand, are not a source document but rather a record of the summaries of transactions which are classified and transferred from the source documents.
