GENERAL LEDGERS. The general ledger control accounts are the basis for financial statement preparation. Revenue cycle transactions affect the following general ledger accounts: sales, inventory, cost of goods sold, AR, and cash. Journal vouchers that summarize activity captured in journals and subsidiary ledgers flow into the general ledger to update these accounts. Thus we have a complete audit trail from the financial statements to the source documents via the general ledger, subsidiary ledgers, and special journals.
