If you’re a small business owner in Denver (or anywhere in Colorado, really), you’ve probably heard the term COGS tossed around by your accountant or bookkeeper. Maybe you even nodded along like, “Yeah, totally, love a good COGS.”

But here’s the thing — Cost of Goods Sold (COGS) isn’t just another accounting acronym. It’s one of the most powerful tools in your financial toolbox. Understanding your COGS can literally change how you price, budget, and scale your business. Let’s break it down in plain English (no finance degree required).
What Exactly Is COGS?
COGS stands for Cost of Goods Sold — basically, it’s what it costs you to make or deliver what you sell.
Think of it as the behind-the-scenes cost of your revenue. For a bakery, that’s flour, sugar, eggs, and packaging. For a landscaping company, it might be mulch, gas, and crew labor.
If you sell services rather than physical products, you might think, “Well, I don’t really have goods.” Not so fast. You probably have direct costs — like subcontractor labor, software licenses, or materials used in client projects. Those count too.
Why COGS Is a Big Deal (No, Really)
Your COGS directly impacts your gross profit, which is the first major measure of how efficiently your business makes money.
Here’s the math:
👉 Revenue – COGS = Gross Profit
If your COGS is too high, your profit margin shrinks — even if your sales look great on paper. That’s why savvy business owners track and tweak their COGS regularly. It helps you:
Price smarter: Know exactly what each sale costs you so you can set profitable prices.
Spot waste: Identify where costs are creeping up (materials, labor, shipping, etc.).
Plan for growth: Forecast how your expenses scale with sales.
In short, understanding COGS keeps your business from running on “vibes” and wishful thinking.
Common Mistakes Small Businesses Make With COGS
Even the most diligent entrepreneurs can trip up here. Some common COGS slip-ups we see at Clearbookz, your friendly Denver bookkeeping team:
❌ Mixing up expenses: Office rent and utilities? Not COGS. Those are operating expenses. Only costs directly tied to your product or service delivery count.
❌ Ignoring small stuff: Forgetting about things like shipping supplies, software, or contractor costs adds up.
❌ Not updating regularly: Your costs change — inflation, supplier pricing, seasonal shifts. If you’re not reviewing your COGS quarterly (at least), your pricing may be off.
