In a credit purchase transaction, the business acquires goods (an asset or expense) and incurs a liability. According to the rules of double-entry bookkeeping, the Purchases account is debited to record the increase in expenses, and the supplier's account (Mr. Z) is credited to record the increase in the liability, as Mr. Z is the creditor.

When goods are given away as charity, the cost of these goods must be removed from the purchases account because they are no longer available for sale. Therefore, the charity account is debited to record the expense, and the purchases account is credited to reduce the total cost of goods purchased, ensuring the inventory records remain accurate.

When goods are removed from inventory for purposes other than sale, such as charity or advertising samples, the original cost of those goods must be removed from the Purchases account. Since Purchases normally carry a debit balance, crediting the account effectively reduces the cost of goods available for sale, ensuring the expense is correctly reclassified to an appropriate expense account like Charity or Advertising.

When goods are given away as charity, the cost of those goods is removed from the purchases account because they are no longer available for sale. Therefore, the charity account is debited and the purchases account is credited to reflect the reduction in inventory cost.

When merchandise is purchased on account, the asset (Purchases) increases, which is recorded as a debit. Simultaneously, the obligation to pay (Accounts Payable) increases, which is recorded as a credit. This follows the accrual basis of accounting, recognizing the liability at the time of the transaction rather than at the time of cash payment.

When a customer makes a payment on their account, the business debits Cash to increase the asset and credits Accounts Receivable to decrease the amount owed by the customer. The credit of $2,100 correctly reduces the outstanding balance of the specific debtor.

When goods are removed from inventory for purposes other than sale, such as charity or advertising (free samples), the original purchase cost must be reduced. Since purchases are initially debited, reducing them requires a credit entry to the purchase account, while the corresponding expense account (e.g., Charity or Advertisement) is debited.

When goods are given away as charity, the 'Charity' account is debited as an expense. Since these goods were originally purchased for resale, the 'Purchases' account is credited to reduce the cost of goods available for sale, effectively removing the cost of the donated items from inventory.

When goods are purchased for cash, the business acquires an asset (purchases/stock) and gives up cash. According to the rules of real accounts, since cash is an asset leaving the business, the cash account must be credited.

Journalizing is the initial step in the accounting cycle where financial transactions are analyzed and recorded in the journal. This process involves identifying the accounts affected, determining whether to debit or credit them based on double-entry rules, and documenting the transaction details. It is distinct from posting, which is the subsequent process of transferring these journal entries into the respective ledger accounts.
