Inventory

Inventory Definition

Inventory is the stock of goods a business holds for sale to customers or for use in producing goods for sale. It includes raw materials, work-in-progress, and finished goods. Inventory is classified as a current asset on the Balance Sheet because it's expected to be sold or used within one year.

Inventory in Practice — Example

A small pet supply shop carries $45,000 worth of inventory: dog food, leashes, toys, grooming supplies, and treats. Each month, they sell about $30,000 in products and restock with new orders. Their bookkeeper tracks inventory in QuickBooks, recording purchases as inventory assets and transferring costs to COGS as items sell. At month-end, the Balance Sheet shows $45,000 in inventory, and the P&L reflects the cost of items actually sold.

Why Inventory Matters for Your Books

Inventory is often a business's largest current asset—and one of the trickiest to manage. Too much inventory ties up cash and risks obsolescence. Too little means lost sales and unhappy customers. Accurate inventory records help you balance these risks.

From a bookkeeping perspective, inventory directly affects both the Balance Sheet and the income statement. When you buy inventory, it's an asset, not an expense. It only becomes an expense (COGS) when it's sold. This distinction is critical—expensing inventory at purchase overstates expenses and understates assets.

Inventory also requires a valuation method (FIFO, LIFO, or weighted average) that affects your cost of goods sold and, consequently, your reported profit and tax liability. Choosing the right method and applying it consistently is essential for accurate financial reporting.

How Inventory Shows Up in QuickBooks

In QBO Plus or Advanced, enable inventory tracking under gear icon → Account and Settings → Sales → Track quantity and price/rate. Create inventory items under Products and Services with cost, selling price, and quantity on hand. QBO uses FIFO automatically. When you create a sales receipt or invoice, QBO reduces the inventory count and moves the cost to COGS. Check the Inventory Valuation Summary report for current values and the Inventory Valuation Detail report for transaction-level detail.

Common Mistakes

Expensing inventory purchases instead of capitalizing them: Buying $10,000 in products to resell is not a $10,000 expense—it's a $10,000 asset until sold. Record it properly as inventory.

Not doing physical inventory counts: QuickBooks tracks theoretical inventory, but shrinkage (theft, damage, spoilage) creates discrepancies. Count physical inventory at least quarterly and adjust the books.

Ignoring obsolete inventory: Products that won't sell are not worth their original cost. Write down obsolete inventory to its net realizable value to keep your Balance Sheet honest.

FAQ

Q: Do service businesses have inventory?

A: Typically no. Service businesses sell labor and expertise, not physical products. However, if a service business resells products (like a salon selling shampoo), those products are inventory.

Q: How often should I count inventory?

A: At minimum, annually. High-volume businesses should do cycle counts (counting a portion of inventory on a rotating basis) monthly or quarterly.
