How to Track Inventory for Your Calgary Retail Business

For Calgary retail businesses, inventory is often your largest asset and your biggest expense. Tracking it accurately is essential for understanding your true profitability, managing cash flow, and filing correct tax returns. Yet many small retailers rely on rough estimates or outdated methods that leave money on the table.

Why Inventory Tracking Matters

Without accurate inventory records, you cannot calculate your true cost of goods sold (COGS), which means your profit and loss statement is unreliable. You may also miss shrinkage (theft, damage, spoilage), over-order slow-moving products, or run out of your best sellers. From a tax perspective, your year-end inventory value directly affects your taxable income.

Perpetual vs. Periodic Inventory

There are two main approaches. Perpetual inventory tracking updates your records in real time as items are bought and sold — this is ideal and is supported by most modern POS systems. Periodic inventory relies on physical counts at set intervals (monthly, quarterly, annually) to calculate COGS. Perpetual is more accurate; periodic is simpler but less reliable.

Setting Up Inventory in Your Accounting Software

QuickBooks Online and Xero both support inventory tracking. Set up each product with its cost price, selling price, and reorder point. Connect your POS system so sales automatically reduce inventory quantities. Reconcile your software inventory against physical counts regularly.

The Physical Count

Even with perpetual tracking, you need periodic physical counts to catch discrepancies. Schedule a full count at least annually (ideally at your fiscal year-end) and spot-check high-value or high-volume items monthly. Document your counts — CRA may request this documentation during an audit.

FIFO vs. Average Cost

CRA allows several inventory valuation methods. FIFO (First In, First Out) assumes the oldest inventory is sold first. Average cost calculates a weighted average cost per unit. Both are acceptable; choose one and apply it consistently. Switching methods requires CRA notification.
