Explanation:

Posting in accounting is when the balances in subledgers and the general journal are shifted into the general ledger. Posting only transfers the total balance in a subledger into the general ledger, not the individual transactions in the subledger. An accounting manager may elect to engage in posting relatively infrequently, such as once a month, or perhaps as frequently as once a day.

Subledgers are only used when there is a large volume of transaction activity in a certain accounting area, such as inventory, accounts payable, or sales. Thus, posting only applies to these larger-volume situations. For low-volume transaction situations, entries are made directly into the general ledger, so there are no subledgers and therefore no need for posting.

For example, ABC International issues 20 invoices to its customers over a one-week period, for which the totals in the sales subledger are for sales of $300,000. ABC's controller creates a posting entry to move the total of these sales into the general ledger with a $300,000 debit to the accounts receivable account and a $300,000 credit to the revenue account.
