The Profitable
Black Friday
Everyone teaches you how to sell in Q4. Nobody tells you whether you actually made money. This does.
You had a record sales week. So why is the bank account lower?
Here’s how most Black Friday sales get measured: the notifications roll in, you add up the revenue, you feel great about the number — and you never check whether that number actually made you any money.
That’s the trap. A discount is the one marketing move that reaches into your profit and takes a cut before you sell a single extra thing. Run it blind and you can absolutely finish a record-revenue weekend with less in the bank than a quiet one.
I spent six years as a government tax auditor, and I now run the books for small businesses. I’ve seen the after-picture of a lot of “successful” sales. This mini-course is the before-picture — the math to run before you commit to a discount, so Q4 leaves you better off instead of just busier.
Six short lessons. One plug-and-play calculator.
The Discount Trap
Why “20% off” costs far more than 20% — and the one number that proves it.
An Offer That Profits
Build a Black Friday deal that wins on value, not on a deeper price cut.
Your Break-Even Number
Exactly how many sales your discount needs before it beats a normal week.
Should You Even Do It?
The honest case for sitting Black Friday out — and how to tell if that’s you.
The Cash-Surge Tax Trap
What a big cash month does to your tax bill, and the reserve rule that keeps you safe.
The January Cash Crash
Why strong-Q4 businesses go broke in Q1 — and how to reserve so yours doesn’t.

Who’s teaching this
I’m Clarissa Wilson — an accountant who’d rather you keep your money than just move a lot of it.
I have a bachelor’s in accounting and two master’s degrees in forensic accounting. I spent six years as a government tax auditor before building Nerdy Number Lovers, where I run the books for small service businesses. I teach the numbers side of running a business without the jargon and without the shame — because you’re smart, you just weren’t taught this.
Quick questions
I’m not “a numbers person.” Will this be over my head?
No. There’s no accounting background required and no math homework — the calculator does the arithmetic. You bring your prices; it does the rest, in plain English.
What if I’m not sure I’ll even run a sale?
Perfect — Module 4 is the honest case for opting out, and the calculator will tell you in fifteen minutes whether a sale is worth it for you at all. That decision alone is worth the price.
Is this tax advice?
No. It’s a planning tool with a sensible reserve rule built in. It helps you make a smarter decision and hold back the right cash — it doesn’t replace filing with your own accountant.
Do I need special software?
The calculator is a standard spreadsheet that opens in Excel or Google Sheets. That’s it.
