The Income Statement covers a stretch of time. The Balance Sheet is a photograph of one day: what you own, what you owe, and what is left over for you.
It has three parts, and they always satisfy Assets = Liabilities + Equity.
Assets — what you own or are owed
Listed roughly in order of how quickly they turn into cash:
- Bank accounts — actual cash.
- Marketplace receivables — money eBay or Amazon is holding that has not paid out yet. Real, and yours, and not in your bank.
- Accounts Receivable — invoices you have sent that customers have not paid.
- Inventory — stock at what it cost you, not what you hope to sell it for.
- Fixed assets — equipment, less depreciation.
Liabilities — what you owe
- Credit cards and any loans.
- Accounts Payable — bills you have received and not paid.
- Sales tax payable — tax you collected from buyers and owe to a state. This is the one that fools people. It sits in your bank account and it is not yours.
Equity — what is actually yours
Owner contributions, plus accumulated profit, minus what you have drawn out. It is a residual: what would remain if you sold every asset at book value and paid off every debt.
The four things it tells you that a profit number cannot
1. Whether your bank balance is really yours. $12,000 in the bank with $4,000 of sales tax payable is $8,000 of spendable money. Sellers spend the $12,000 and are surprised by the remittance.
2. How much money is stuck in the middle. Add up marketplace receivables. That is money you have earned and cannot spend yet. If it keeps growing, your payout timing is financing your customers.
3. Whether growth is eating you. Compare inventory over months. Rising inventory with flat sales is cash converting into boxes.
4. What you would owe if you stopped tomorrow. Total liabilities, on one line.
Reading it against the Income Statement
The two answer different questions and you need both:
| Income Statement | Balance Sheet | |
|---|---|---|
| Covers | A period | A single day |
| Answers | Did we make money? | What do we have, and what do we owe? |
| Misses | Where the money went | Whether this period was any good |
A profitable month where cash fell is not a contradiction — it is one report showing the profit and the other showing that it went into stock.
When it does not balance
It always should. Assets minus liabilities is defined as equity, so the two sides cannot disagree unless something is recorded wrong.
That is why the check matters: it is a test that can actually fail, and a failure means a real problem — a missing entry, a one-sided posting, an amount recorded twice. A report that always looks plausible tells you nothing.
