Process
How to Choose Your Inventory Method
Finding the right approach for your business in four steps.
01
Understand Your Product Flow
Do items sell in order received? Or do you rotate stock regularly? Understanding your actual inventory movement helps you pick a realistic method.
02
Review Tax and Reporting Rules
CRA allows FIFO and weighted average for tax purposes. ASPE requires consistent application. We’ll explain the rules that apply to you.
03
Calculate Impact on Profits
Each method produces different COGS and ending inventory values. We show you side-by-side comparisons so you see the financial impact.
04
Document and Implement
Once chosen, document your method in your accounting policies. Consistency matters for audits and financial credibility with lenders.
Why This Matters
Inventory Accounting Affects More Than You Realize
Your inventory method doesn’t just determine COGS. It shapes your tax bill, your financial ratios, and how lenders view your business. Getting it right means accurate statements and confident decision-making.
We’re focused on making these concepts clear. No jargon. No assumptions that you already understand depreciation or weighted averages. We start with the basics and build up to real applications.

Questions
Common Questions About Inventory Methods
Quick answers to help you understand the differences and implications.
Can I change my inventory method after I’ve chosen one?
CRA allows changes but requires formal approval and detailed documentation of the impact. It’s not impossible but it’s complicated. Better to get it right from the start.
Which method saves the most taxes?
During inflation, FIFO typically results in higher COGS and lower profits — reducing tax. Weighted average smooths the effect. Your actual tax outcome depends on your prices and sales patterns, not the method alone.
Do I need to physically count inventory every year?
Most Canadian businesses do annual counts. Some use cycle counting throughout the year instead. Your auditor will have expectations based on your industry and size.
What’s the difference between perpetual and periodic inventory?
Perpetual updates records continuously (usually with software). Periodic counts once per period. Most modern businesses use perpetual but verify with physical counts.
Does inventory method affect my balance sheet?
Yes. Ending inventory appears on the balance sheet. FIFO and weighted average produce different ending inventory values — which changes your total assets and working capital ratios.
What records do I need to keep for CRA?
Document your method choice, maintain detailed inventory records, keep purchase invoices, and preserve physical count sheets. CRA can audit back six years — so keep records that long.

“I wasn’t sure which method to choose when I started my retail shop. These guides broke it down so clearly that I actually understood the difference between FIFO and weighted average. I went with weighted average because my costs fluctuate a lot, and the guide showed me exactly why that made sense for my business.”
— Marcus, retail owner
“Our accountant kept saying we needed to reconcile inventory but didn’t explain what that meant. Found the reconciliation guide here and suddenly it made sense. We’ve actually caught discrepancies now that we’re doing it properly.”
— Jennifer, warehouse manager
“The FIFO explanation with real examples was exactly what I needed for my bookkeeping course. It’s not overly technical but it’s also not dumbed down. I’m recommending it to other students.”
