Your Pro Shop and Restaurant are more than just amenities; they are critical profit centers. The merchandise within them—from the latest drivers and seasonal apparel to the food and beverage stock—represents one of the largest and most dynamic assets on your club’s balance sheet. Managing this asset effectively is fundamental to your financial health.
However, true inventory management goes far beyond simply tracking stock levels.
You must be able to accurately determine its value, a process governed by inventory costing methods. Choosing the right method is not just an accounting decision; it’s a strategic choice that directly impacts your reported profits, tax obligations, and purchasing decisions.
This guide will demystify the essential inventory costing methods and highlight the one non-negotiable principle every golf manager must master: the lower of cost or market method.
Why Inventory Costing is a Non-Negotiable Skill
At its core, inventory costing is about assigning a value to the items you sell (Cost of Goods Sold – COGS) and the items that remain in stock (ending inventory). An inaccurate COGS calculation leads to misleading profit margins, while an overvalued inventory inflates the value of your assets, painting a dangerously inaccurate picture of your club’s financial stability.
Let’s explore the most common methods with practical examples from a golf club environment.
Method 1: FIFO (First-In, First-Out)
This is the most intuitive method. It assumes that the first items you purchase are the first ones you sell.
- How it Works: Imagine your pro shop receives a shipment of 20 Peter Millar polo shirts at a cost of $50 each in March. In May, due to inflation and supplier price hikes, you receive another shipment of the same 20 shirts, but this time they cost $55 each.
- The FIFO Scenario: When you sell a shirt in June, FIFO assumes you sold one of the original shirts from the March shipment. Therefore, you record a COGS of $50. Your remaining inventory is valued at the more recent, higher cost.
- Pros for Golf:
- Logical Flow: It aligns with the physical reality of selling older merchandise first to avoid obsolescence, which is critical for seasonal apparel and date-sensitive products like golf balls.
- Widely Accepted: It is a universally recognized accounting principle (GAAP).
- Cons:
- Higher Tax Burden: In periods of rising prices (inflation), FIFO results in a lower COGS and thus a higher reported gross profit, which can lead to a higher income tax liability.
Method 2: Weighted Average Cost (WAC)
This method smooths out price fluctuations by calculating a single average cost for all identical items in stock.
-
How it works:
Let’s say you buy 50 dozen Titleist Pro V1 balls in April at $40 each, and another 50 dozen in July at $44. That gives you 100 dozen total, with a combined cost of $2,000 + $2,200 = $4,200.
- The WAC Scenario: The weighted average cost is $4,200 ÷ 100 = $42 per dozen. So, every time you sell a dozen—regardless of which batch it comes from—you record a cost of goods sold (COGS) of $42.
- Pros for Golf:
- Simplicity: It’s much easier than tracking individual cost batches, especially for high-volume, identical items like golf balls, tees, or standard restaurant ingredients.
- Stable Margins: It prevents dramatic swings in your reported profit margins with each sale.
- Cons:
- Less Precise: The COGS never reflects the actual cost of a specific purchase, which can mask the true profitability of certain inventory batches.
The Golden Rule for Preventing Losses: The Lower of Cost or Market (LCM) Method
This isn’t a standalone costing method like FIFO or WAC. Instead, it’s a crucial, overriding principle of conservative accounting that you must apply to prevent your balance sheet from being misleadingly optimistic.
The lower of cost or market method dictates that you must value your inventory at either its original recorded cost or its current market value, whichever is lower.
Why This is crucial for a Golf Business
The golf industry is uniquely susceptible to factors that rapidly decrease the value of inventory. The LCM method forces you to acknowledge these realities financially.
- Expert Example 1: Seasonal Apparel. It’s August. Your pro shop is still holding onto five high-end winter jackets that cost you $200 each. Their original total cost is $1,000. However, no one is buying winter jackets in a heatwave. To clear them out before they are a year old, you’d be lucky to sell them for $120 each. Their market value is now $120. Under the LCM rule, you are required to write down the value of this inventory from $200 to $120 per jacket, recognizing a $400 loss now, not when (or if) they eventually sell.
- Expert Example 2: Equipment Obsolescence. TaylorMade has just announced their new Qi10 driver. Instantly, the market value of the 15 brand-new Stealth 2 drivers you have in stock plummets. You paid $450 for each, but their current market value (what a customer is willing to pay) might only be $350. The LCM method requires you to recognize this $100 per club loss immediately, adjusting your inventory asset value downwards by $1,500.
Applying the LCM method ensures your assets aren’t overstated and gives you a true picture of your profitability by accounting for unrealized losses.

Putting Theory into Practice: The Role of Inventory Management Software
Manually tracking different cost batches for FIFO or constantly recalculating the Weighted Average Cost across hundreds of SKUs is a recipe for errors and wasted time. Applying the LCM method requires even more vigilance.
This is where a dedicated inventory platform becomes indispensable. An advanced Stock module is the engine that makes these professional accounting practices possible.
- Automated Cost Tracking: A system like Golfmanager automatically records the cost of inventory from each purchase order. This provides the foundational data needed to apply either FIFO or WAC accurately without manual spreadsheets.
- Real-Time Sales Data: By seeing what’s selling and, more importantly, what isn’t, you can quickly identify slow-moving items that may require a market value assessment under the LCM rule.
- Supplier & Invoice Management: Centralizing supplier information and costs ensures your initial “cost” data is always accurate, leading to reliable valuations.
- Informed Decision Making: With clear reports on inventory value and turnover, you can make timely decisions to discount merchandise and apply LCM write-downs, protecting the club’s overall financial health.
Stop Guessing Your Inventory Value
By implementing a structured method and applying the key principle of lower of cost or market, you’ll gain real financial control over your profit centers.
