Comprehensive Notes on Purchase Discounts, Shipping Terms, and Inventory Costing

Credit Purchase Mechanism:
- Suppliers frequently extend credit terms to business customers, granting a specific window (e.g., $30\,\text{days}$ ) to pay for purchases made on account.
- To incentivize prompt payment, suppliers offer purchase discounts.
Purchase Terms and Invoice Notation:
- Purchase terms are explicitly stated on the supplier's invoice to display available discounts.
- Common invoice notation format: $2/10$ (pronounced "two slash ten").
- The numerator ( $2$ ) represents the cash discount percentage ( $2\%$ ).
- The denominator ( $10$ ) represents the discount period duration in days ( $10\,\text{days}$ ).
- Mechanics of $2/10$ terms:
- Pay within $10\,\text{days}$ : Receive a $2\%$ discount off the invoice amount.
- Pay between day $11$ and day $30$ : No discount is allowed, and the full invoice price must be paid.
Financial Implication of Foregoing Discounts:
- Failing to take advantage of prompt payment discounts carries a severe implicit interest cost.
- Passing up a $2/10$ discount on a net $30\,\text{day}$ invoice is equivalent to paying an annualized interest rate of approximately $36.5\%$ .
- Business managers must take advantage of purchase discounts to prevent substantial value loss.

Overview of Shipping Terms:
- Shipping terms define the official transfer point of title ownership for goods moving from seller to buyer (e.g., from California to destination).
- Terms establish which party owns goods while in transit, which party bears shipping costs, and when each party records inventory in their accounting system.
Free On Board (FOB) Shipping Point:
- Ownership and title of goods transfer to the buyer immediately when the seller hands the goods to the carrier at the shipping point.
- Ownership in Transit: Goods in transit belong entirely to the buyer.
- Freight Costs: The buyer pays for shipping costs (referred to as freight-in or transportation cost).
- Accounting Treatment:
- The buyer must record the inventory in their accounting system immediately upon shipment as "in transit," even prior to physical delivery.
- The buyer adds the freight costs directly into the asset value of the inventory.
Free On Board (FOB) Destination:
- Ownership and title remain with the seller while goods are in transit.
- Ownership in Transit: Goods belong to the seller until delivery reaches the buyer's destination.
- Freight Costs: The seller pays all shipping and delivery costs.
- Accounting Treatment:
- The seller records freight expenses as delivery expense or shipping expense on the income statement.
- The buyer records inventory only upon physical arrival at their destination.

Calculation of Purchase Discount and Net Payable:
- Initial Purchase Invoice Amount: $\$10,500$
- Applied Purchase Discount Rate: $2\%$
- Discount Calculation: $2\% \times \$10,500 = \$210$
- Net Amount Due: $\$10,500 - \$210 = \$10,290$
Balance Sheet Impact:
- Liabilities: Settled or reduced by the net cash outlay required ( $\$10,290$ ).
- Inventory Asset Value: The $2\%$ discount ( $\$210$ ) directly decreases the carrying value of inventory cost on the balance sheet because the actual acquisition cost is lower.
Income Statement Impact:
- Receiving a purchase discount or returning inventory does not affect the income statement at the time of the transaction.
- As long as the purchased items remain unsold in the warehouse, no gain, loss, or expense is recognized on the income statement.
- The reduced inventory cost flows to the income statement under Cost of Goods Sold (COGS) only when the inventory is eventually sold.

Multi-Step Inventory Cost Calculation Walkthrough:
- Initial Inventory Purchase Cost: $\$45,000$
- Terms Offered: $1/10$ ( $1\%$ discount if paid within $10\,\text{days}$ )
- Transportation / Freight Cost Paid (FOB Shipping Point): $\$700$
- Purchase Discount Earned: $1\% \times \$45,000 = \$450$
- Net Inventory Adjustment for Purchase 1: $\$45,000 + \$700 - \$450 = \$45,250$
- Additional Inventory Purchase: $\$40,000$
- Total Cost of Inventory Available for Sale: $\$93,750$
Ending Inventory Determination:
- Total Inventory Available for Sale: $\$93,750$
- Cost of Inventory Sold: $\$56,000$
- Ending Inventory Balance: $\$93,750 - \$56,000 = \$37,750$

Handling Inventory Returns:
- Question: What is the effect of returning inventory items before they are sold, such as an item valued at $\$8$ ?
- Response: Returning inventory reduces the inventory balance and reduces liabilities/cash by $\$8$ . Because the returned items were not sold, the return does not affect the income statement.
Timing of Income Statement Effects:
- Question: Why doesn't obtaining a discount or returning goods appear on the income statement?
- Response: Income statement recognition requires a sale transaction. Purchase returns and discounts alter the asset carrying value of inventory on the balance sheet. So long as inventory remains intact in the warehouse, no impact hits the income statement.
Consequences of Paying Outside Discount Terms:
- Question: What occurs if payment is made without taking the discount?
- Response: If payment occurs after the discount period expires (e.g., after day $10$ under $2/10$ terms), the full original balance must be remitted without inventory cost reduction, forfeiting an annualized effective saving rate of $36.5\%$ .
