Operating Cycle of a Merchandiser
Spans the entire duration from the purchase of merchandise until cash is collected from customers through merchandise sales.
Sequential stages in the credit operating cycle:
Cash outflow: Initial liquidity used for acquiring stock.
Purchases (a): Acquisition of goods from vendors.
Merchandise Inventory (b): Storage and holding of products prior to sale.
Credit Sales (c): Conveyance of merchandise to buyers on account.
Accounts Receivable (d): Short-term legal claim to customer cash.
Cash Collection (e): Settlement of receivables returning funds to cash balance.

Inventory Systems Overview
Perpetual Inventory System
Dynamically updates accounting records immediately for each purchase and each individual sale of inventory.
Continuous record-keeping ensures real-time availability of inventory and cost of goods sold figures.
Periodic Inventory System
Updates accounting records for purchases and sales only at the end of a discrete accounting period.
Requires a physical count at the period's end to establish ending inventory balance and calculate cost of goods sold.
Fundamental Inventory Cost Flow Identity
Beginning inventory balances combined with net acquisitions during a period define the total inventory pool:
The pool of merchandise available for sale is allocated into two destinations at the close of an accounting interval:
Cost of Goods Sold is recognized as an expense on the income statement.
Ending Inventory is reported as a current asset on the balance sheet, which directly rolls forward to become the Beginning Inventory of the consecutive subsequent operating period.
Accounting for Merchandise Purchases Using a Perpetual System
Cash Purchases of Merchandise
When merchandise is acquired outright for liquid funds, the asset Merchandise Inventory increases with an equal decrease in Cash.
Transaction illustration: On November 2, Z-Mart purchases of merchandise inventory for cash.
Debit: Merchandise Inventory
Credit: Cash
Credit Purchases and Terms of Sale
Sellers offer cash discounts (referred to as purchase discounts by the buyer) to incentivize early invoice liquidation.
Credit Term Structure (e.g., )
: Discount percent (
: Number of days the discount is available from invoice date (discount period).
: Net (or all) balance due if discount window expires.
: Total credit period duration in calendar days from the invoice date.
Invoice Documentation Details
Core fields include Seller (Trex, Antigo, WI), Purchaser (Z-Mart, Chicago, IL), Invoice Date (11/2/27), Invoice Number (4657-2), Purchase Order Date (10/30/27), Salesperson (#141), Credit Terms (), Freight Terms (FOB Destination), Carrier (FedEx).

Gross Method for Purchases with Cash Discounts
Initial Purchase Entry
On November 2, Z-Mart purchases of merchandise inventory on account with credit terms .
Recorded at full gross invoice value:
Debit: Merchandise Inventory
Credit: Accounts Payable
Settlement within Discount Period
On November 12, Z-Mart pays the invoice within the 10-day discount window.
Discount amount: \500 \times 2\% = \.
Cash payment required: \500 \times (100\% - 2\%) = \.
Under a perpetual system, the discount reduces the recorded asset value of inventory directly:
Debit: Accounts Payable
Credit: Merchandise Inventory
Credit: Cash
Ledger account balances following posting:
Accounts Payable:
Merchandise Inventory:
Cash: credit outflow
Settlement after Discount Period
On December 2, Z-Mart pays the full gross obligation outside the discount window.
No discount recognized:
Debit: Accounts Payable
Credit: Cash
Purchases Returns and Allowances
Definitions
Purchase Allowance: A negotiated price reduction granted by the supplier for defective, imperfect, or unacceptable goods kept by the purchaser.

Goods in transit are owned legally by the Seller.
Freight costs are paid by the Seller (transportation-out / delivery expense).
Accounting entry by seller: Expense incurred to deliver products, reported under selling operating expenses.

Accounting for Merchandise Sales Using a Perpetual System
Two-Part Nature of Merchandising Sales Entries
Under a perpetual inventory system, every single sale requires recording two distinct accounting components:
Revenue Entry: Increase in assets (Cash or Accounts Receivable) matched with an increase in Sales revenue at the agreed selling price.
Cost Entry: Increase in expenses (Cost of Goods Sold) matched with a decrease in assets (Merchandise Inventory) at historical cost.
Credit Sales without Cash Discounts
Transaction: On November 12, Z-Mart sells of merchandise on credit. The merchandise has a recorded cost basis to Z-Mart of .
Revenue side:
Debit: Accounts Receivable
Credit: Sales
Cost side:

Credit: Merchandise Inventory
Sales with Cash Discounts
Sales discounts offer early settlement incentives, reducing liquidity delays and lowering subsequent collection effort expenses.
Sales Discount is a contra-revenue account with a normal debit balance subtracted directly from Sales.
Baseline transaction: On November 12, Z-Mart sells of merchandise on credit with terms .
Initial entries on November 12:
Debit: Accounts Receivable
Credit: Sales
Debit: Cost of Goods Sold
