What is a subledger?

A subledger is a detailed record that supports the general ledger accounts, providing more granular information about specific transactions and balances. For instance, in accounts receivable, a subledger would contain all individual customer invoices, payments received, and outstanding balances, allowing for a detailed view of each customer's account. This detailed record helps organizations reconcile their accounts and ensure accuracy in financial reporting.

In contrast, the other options do not accurately define a subledger. A simplified version of financial statements would not capture the ongoing detailed transactions necessary to support the general ledger, while an overview of a company's marketing strategies pertains more to strategic planning than accounting. Similarly, a record of employee annual salaries relates specifically to payroll rather than being a component of accounting ledgers. Therefore, the correct choice highlights the subledger's critical role in complementing the general ledger with detailed transaction information that aids in financial management.
