Posting is the accounting step where you transfer recorded transactions from the journal to the general ledger. Each journal entry gets posted to the specific account it belongs to — whether that is cash, accounts payable, or revenue.
For example, if you recorded a $5,000 sale in the journal, posting means updating the sales account (credit $5,000) and the cash or receivables account (debit $5,000) in the ledger.
Posting is a critical step in the accounting cycle. Without it, your ledger accounts would not reflect the latest transactions, and your financial statements would be incomplete.
