Let’s play a quick game.
You’re in the cockpit of a jet. Dials everywhere: altitude, airspeed, fuel, cabin pressure.
Now , fly the plane.
Problem?
Nobody told you what those dials mean.
That’s exactly how most e-commerce sellers feel when they look at their Profit & Loss (P&L) statement.
Numbers spinning. Alarms buzzing. No idea what’s going on.
Today, we’ll fix that.
I’m going to show you how to read your P&L like a pro even if you hate numbers.
Because once you understand your P&L, you’ll have the ultimate weapon for building a healthy, profitable business.
1️⃣ Revenue — More Than Just Sales
At the top of your P&L, you’ll see Revenue (or Sales).
But it’s not just the number on your Shopify dashboard.
True Revenue must account for:
- Refunds
- Chargebacks
- Discounts
- Cancelled orders
👉 At Blu Hat Bookkeeping, we ensure you’re tracking Net Revenue, not inflated vanity numbers.
2️⃣ Cost of Goods Sold (COGS) — The Real Cost of Selling
COGS includes:
- Product manufacturing/purchase costs
- Freight & import duties
- Packaging
- Amazon FBA fees
Revenue – COGS = Gross Profit.
This is a critical number. It shows if your products are even worth selling.
👉 Most sellers underestimate their COGS. We make sure you don’t.
3️⃣ Gross Profit Margin — The Reality Check
Formula:
(Gross Profit ÷ Revenue) x 100
- 60% margin? Great.
- 30%? You need to monitor expenses closely.
👉 Many 7-figure sellers are unknowingly running on razor-thin margins.
4️⃣ Operating Expenses — Where the Money Goes
This is where sellers lose control:
- Ads (Facebook, Google, TikTok)
- Software subscriptions (Shopify, Canva, Klaviyo)
- Contractors & freelancers
- Rent, internet, utilities
- Professional services (bookkeeper, tax pro)
👉 We categorize every dollar so you know where your money’s going.
5️⃣ Net Profit — The Only Number That Really Matters
Revenue – COGS – Operating Expenses = Net Profit.
This is the money you actually keep.
It pays your bills, taxes, and fuels business growth.
👉 Everything else is noise. Net Profit is king.
6️⃣ The Profit Trap Most Sellers Fall Into
Revenue grows.
But profit stays flat or shrinks.
Why?
- Ad costs spike.
- Subscription apps pile up.
- Platform fees quietly eat margins.
- Inventory bloats cash flow.
👉 A monthly P&L review keeps you focused.
At Blu Hat Bookkeeping, we don’t just send reports, we help you understand them.

👉 Your P&L isn’t just for tax season, it’s your business scoreboard.

- Control your expenses.
- Protect your profits.
