What is a source document and why is it important in the revenue cycle?

• A. A source document captures initial data for a transaction (e.g., sales order, invoice) and ensures traceability.
• B. A source document is used only for tax purposes.
• C. A source document is a digital record of ledger entries after posting.
• D. A source document is used to approve budgets.

Answer: (A)

In the revenue cycle, a source document is the original record that captures data about a transaction as it happens, before anything is posted to the accounting system. It serves as the factual evidence of what occurred and provides the details needed to record the event accurately—things like customer, items or services, quantities, prices, dates, and terms. This is why the source document is key: it starts the data flow, ensuring the information entered into the system is complete and accurate. It also creates a clear audit trail, so you can trace a recorded transaction all the way back to the original record, verify authorization, and reconcile postings if needed. Examples include sales orders, packing slips, invoices, and cash receipts—the documents that originate the entries in journals and ledgers. Other statements miss the point because source documents aren’t used only for tax purposes, aren’t simply digital records after posting, and aren’t primarily tools for approving budgets. They are the initial pieces of evidence that initiate and support recording in the revenue cycle.
