If you sell physical products, your inventory isn't just stock sitting on a shelf—it's a major asset that directly impacts your profits, taxes, and financial reporting.

In this episode of The Secret Life of Inventory, we break down inventory valuation methods in simple terms. You'll learn the difference between price and cost, how Cost of Goods Sold (COGS) works, and why choosing the right inventory costing method can have a big impact on your business.

We cover the three most common inventory costing methods:
→ FIFO (First-In, First-Out)
→ LIFO (Last-In, First-Out)
→ Moving Average Cost

Plus, we explain the differences between IFRS and GAAP accounting standards, discuss which industries benefit most from each costing method, and share practical advice for choosing the right approach for your business.

Whether you're managing inventory in spreadsheets, evaluating inventory software, or trying to better understand your financial statements, this episode will help you connect inventory operations with accounting fundamentals.
