Finance 101 Textbook
The complete owner's guide to running the money side of your business without a finance degree. Know exactly where your money is, where it is going, and how much you actually get to keep.
Five layers. Bottom up. The order matters.
Everything in the Textbook
The five layers of your money system, in the order you build them. Every tile is a working chapter with templates and worked math.
CHAPTER 1The 15-Minute Quick Win
Before you read anything else in this book, do this one exercise. It changes how you read the rest.
Open your bank account. Get one number: total cash on hand right now. Then open last month's P&L (or your accounting software) and get one more: your total monthly expenses.
Divide the first by the second.
=
Cash in bank ÷ Monthly expenses
That number is your survival window. Everything else in this book is downstream of it.
- Under 1 month: crisis territory. One bad month wipes you out.
- 1 to 3 months: fragile. One customer leaving hurts.
- 3 to 6 months: safe. You can handle normal turbulence.
- 6 to 12 months: strong. You can invest strategically without panic.
- 12+ months: excellent. You have real optionality.
Target: get to at least 3 months as fast as possible. Then work toward 6.
If you finished this exercise and your runway is under 3 months, close the book here and go build the 13-week cash flow forecast in Chapter 4. Everything else waits.
CHAPTER 2Why Money Feels Confusing
If you are reading this, one of these is true:
- You have money in the bank but you are not sure if you are actually profitable.
- You get a P&L from your bookkeeper monthly but you do not really understand what it says.
- You know you should raise prices but you are afraid customers will leave.
- Payroll comes and you scramble even though you knew the date months ago.
- You are not sure if you are taking home enough or too much as owner.
- You get anxious every April about taxes because you have no idea what you owe.
- You have thought about "hiring a CFO" but that feels expensive and premature.
All seven have the same root cause: nobody ever showed you the money system.
Business owners are not taught finance. School did not teach it. Your first job did not teach it. Even your bookkeeper often does not teach it. They just do the work and hand you a report you cannot read.
It doesn't have to be that way. The money layer is the layer where you actually get to keep the fruits of everything else. Great marketing plus great sales plus great ops can still leave you broke if the money layer is broken. A mediocre business with an excellent money layer builds wealth over time.
This textbook is the money layer. Not accounting theory. Not corporate finance. The actual mechanics of running the money side of a small business, explained so you understand it without a finance degree.
CHAPTER 3The 5-Layer Money Stack
Every business's money situation sits on five layers, stacked in order. Build them bottom to top. Never top to bottom.
Layer 1: CASH. Money in the bank. Timing of what comes in vs. what goes out. Runway.
Layer 2: PRICING. What you charge. The single biggest lever most owners never touch.
Layer 3: MARGINS. What you keep from each dollar of revenue. Gross margin, net margin, unit economics.
Layer 4: STATEMENTS. Your P&L, balance sheet, and cash flow statement. The three views of financial reality.
Layer 5: RESERVES + TAXES. Emergency fund, tax reserves, owner distributions. The protection layer that keeps a good year from turning into a disaster the next.
The build order (and why it matters)
- If Cash is broken (Layer 1), everything else is theoretical. You might not survive to see it.
- If Pricing is broken (Layer 2), you cannot fix Cash with more sales because more sales at bad prices makes it worse.
- If Margins are broken (Layer 3), scaling makes things WORSE, not better.
- If Statements are broken (Layer 4), you are flying blind. You cannot tell if any change is working.
- If Reserves are broken (Layer 5), one bad quarter wipes out three good ones.
CHAPTER 4Sample Template: The 3 Reserve Accounts
The protection layer sits on three separate bank accounts. Open all three. Automate every deposit.
Why this works: you never accidentally spend the IRS's money. You never take an owner draw that starves payroll. And when a bad month hits, the operating reserve absorbs it instead of your credit card.
Your exact percentages depend on tax bracket, entity structure, and personal situation. Work with a CPA to set YOUR numbers. The STRUCTURE of 3 reserve accounts plus operating account is universally correct.
CHAPTER 5AI Prompt Pack (Preview)
The full book ships with 10 copy-paste AI prompts. Paste into ChatGPT or Claude, replace the brackets, iterate. Here are 5 you get.
CHAPTER 6The 5 Money Metrics That Matter
Not the 40 metrics your accounting software shows. These 5. Track weekly for #1. Monthly for the rest. Ignore everything else.
The rule: if a metric does not tell you what to do differently this week or this month, it is noise. Kill it from your dashboard.
CHAPTER 73 Common Mistakes That Kill Businesses
The full book lists 10. These 3 kill more owners than the other 7 combined.
Mistake 1: No cash flow forecast. Surprised by every payroll. Fix: build the 13-week forecast this week. Never be surprised by cash again.
Mistake 2: Underpricing. Working 60-hour weeks for 5% margin. Fix: run the value-based pricing math in Chapter 4. Raise prices with the 5-step sequence.
Mistake 3: No tax reserve. April surprise every year, penalties on top. Fix: open the 3 reserve accounts this week. Automate the split on every deposit.
Every mistake in the full list of 10 has bankrupted otherwise good businesses. Every fix is in the templates that come with this book.
The One Thing To Do Today
Before you close this file, do this ONE thing:
Open your bank account. Get your cash on hand. Open your last month's P&L. Get your monthly expenses. Divide. That is your runway in months. Write it on a sticky note and put it on your monitor.
If your runway is under 3 months, build the 13-week forecast this week. If it is 3 to 6, open the 3 reserve accounts. If it is over 6, run the unit economics on your top service. There is a next action for every state. Pick yours.
Go do it. Come back for the rest.
