Generally accepted accounting principles (GAAP) and cash accounting methods treat post-dated checks the same way---no journal entry recording. A post-dated check is essentially a promise to pay, and until the business partner pays or reimburses amounts owed, no change is made in accounting books. To illustrate, an accounting clerk receives a $45,000 post-dated check negotiable in one week. She cannot debit cash (asset) and credit sales revenue or accounts receivable to record this transaction because no payment is made. She can, however, write a memo about the post-dated check in the accounting ledger. (Bookkeepers debit asset accounts to increase their balances and credit revenues to increase their amounts). If the check clears the customer's bank after one week, the clerk may then record journal entries in the sales ledger.
