Small Business Finance: A Practical Guide for Founders
Small Business Finance sounds complicated because it’s often explained badly.
Founders are thrown words like profit, cash flow, burn rate, and financial statements, with no one stopping to explain what those terms actually mean or why they matter day to day.
This guide explains Small Business Finance from the ground up, in plain English, for US founders who didn’t study accounting and don’t want to.

Why Most US Small Businesses Struggle Financially
Let’s start with the uncomfortable truth:
Most small businesses don’t struggle because they aren’t selling. They struggle because they don’t understand their money.
Here’s what that usually looks like:
- Money is coming in, but the bank balance still feels tight
- Taxes are a surprise every year
- The founder can’t tell if the business is actually profitable
- Decisions are made based on gut feeling, not numbers
In the United States, this is risky because tax rules are strict, cash moves fast, and mistakes compound quickly.
Before We Go Further: Key Small Business Finance Terms (Explained)
Before we go further, let’s define the terms.
Small Business Finance simply means:
How money enters your business, how it leaves, how much stays, and whether that’s sustainable.
It includes:
- How you get paid
- How you pay expenses
- How you track all of it
- How taxes are calculated
- How long your cash will last
That’s it. No mystery.
Revenue
The total money your business earns from customers before any expenses are deducted.
Expenses
The costs required to run your business—software, staff, rent, marketing, tools, and services.
Profit
What’s left after expenses are subtracted from revenue.
(Revenue − Expenses = Profit)
Cash
The actual money sitting in your bank account right now.
Cash Flow
How money moves in and out of your business over time—not just how much you earn.
Burn Rate
How much cash your business uses each month when expenses are higher than income.
Bookkeeping
The process of recording, organising, and categorising every financial transaction.
Financial Statements
Simple reports that summarise your finances, such as profit, cash position, and what you owe.
If these are clear, the rest of Small Business Finance becomes much easier.
What “Good Financial Foundations” Actually Mean (In Simple Terms)
When people say “get your finances in order,” they usually mean four basic things.
1. You can see where your money goes
You know how much comes in and exactly what it’s spent on.
2. Your numbers are accurate
Your bank balance matches your records. No guessing.
3. You understand the basics
You know the difference between:
- Revenue
- Profit
- Cash
(We’ll explain these shortly.)
4. You’re not afraid of your numbers
You can look at them monthly without panic.
That’s a strong Small Business Finance foundation.
How US Small Businesses Should Structure Their Finances
Financial structure is just how you organise money.
For most US small businesses, this means:
Separate personal and business money
This is non-negotiable.
Personal spending must never mix with business spending.
One main business bank account
This is where customer payments arrive and expenses are paid from.
Optional but smart: sub-accounts
Many founders use:
- An operating account (daily expenses)
- A tax account (money set aside for taxes)
This structure makes Small Business Finance simpler and safer.
Revenue vs Profit: Explained Simply (And Why the IRS Cares)
These two terms are constantly confused.
Revenue (also called “sales” or “income”)
Revenue = all the money your business receives from customers.
Example:
You invoice $10,000 this month → Revenue is $10,000.
Profit
Profit = what’s left after expenses.
If your expenses were $7,000:
$10,000 − $7,000 = $3,000 profit
Why this matters
The Internal Revenue Service taxes profit, not revenue.
You can have high revenue and still:
- Owe little tax (low profit), or
- Owe a lot of tax (high profit)
Understanding this is foundational Small Business Finance.
Cash vs Profit: The Most Confusing Concept for Founders
This is where many businesses get into trouble.
Cash
Cash = money in your bank account right now.
Profit
Profit = a calculation on paper.
You can:
- Be profitable but run out of cash
- Have cash but not be profitable
Example:
You invoice a client $20,000, but they pay in 60 days.
You’re profitable but you don’t have the cash yet.
This gap is why Small Business Finance matters so much.
Understanding Financial Statements (Plain English)
Financial statements are just summaries of your money.
Profit & Loss (P&L)
Answers:
“Did we make money over this period?”
It shows:
- Revenue
- Expenses
- Profit or loss
Balance Sheet
Answers:
“What do we own and owe right now?”
It shows:
- Assets (cash, equipment, money owed to you)
- Liabilities (loans, bills, taxes owed)
Cash Flow Statement
Answers:
“Where did cash actually move?”
This is the survival report.
Founders don’t need to memorise formulas, they just need to understand what question each report answers.

Burn Rate: Explained for Non-Financial Founders
Burn rate is one of the most important Small Business Finance terms, and one of the least explained.
Burn rate means:
How much cash your business uses each month.
Example:
- You spend $8,000 per month
- You earn $5,000 per month
- You are burning $3,000 monthly
Why burn rate matters
Burn rate tells you:
- How long your cash will last
- When you’ll need to cut costs or grow revenue
- Whether hiring is safe or risky
Ignoring burn rate is how businesses shut down suddenly.

Choosing the Right Business Bank Account
Your bank account is the source of truth for Small Business Finance.
A good US business bank account should:
- Clearly show every transaction
- Work with accounting software
- Make taxes easier, not harder
If your bank data is messy, everything downstream breaks.
Bookkeeping: What It Is and Why It Matters
Bookkeeping means recording what happened to your money.
In simple terms:
- Money in → record it
- Money out → categorise it
- Match records to the bank
Good bookkeeping ensures:
- Financial statements are accurate
- Taxes are calculated correctly
- Decisions are based on facts
Bad bookkeeping leads to confusion, stress, and expensive fixes.
Common Financial Setup Mistakes (Explained Simply)
Here’s what founders commonly get wrong:
- Waiting “until later” to set things up
- Assuming the accountant will fix everything
- Looking at bank balance instead of cash flow
- Guessing tax bills instead of planning
These are not intelligence problems, they are education gaps.
Final Word: Finance Is a Skill, Not a Personality Trait
You don’t need to be “good with numbers” to master Small Business Finance.
You just need clear explanations and the right systems.
If this feels overwhelming, that’s normal—this is exactly where Tookand helps founders get clarity.
