Learn It
Many people learn the P&L, the Balance Sheet, and the Statement of Cash Flows as if they were three separate things. They are not. They are three views of the same bookkeeping system.
When a business records a transaction, that single event can affect two or three statements at the same time. Understanding these connections is what separates someone who can produce reports from someone who actually understands the books.
As we covered in the Accounting Equation, every transaction has at least two effects. Those effects show up across the statements.
The Key Connections
Revenue → Net Income → Equity
Revenue on the P&L increases net income. Net income flows into equity on the Balance Sheet as Current-Period Earnings. Profit grows the owner's share.
Invoicing → Revenue + Accounts Receivable
When a business invoices a customer, revenue appears on the P&L and Accounts Receivable appears on the Balance Sheet at the same time. As we covered in Accounts Receivable, the receivable sits on the Balance Sheet until the customer pays.
Bills → Expenses + Accounts Payable
When a business receives a bill, an expense appears on the P&L and Accounts Payable appears on the Balance Sheet. As we covered in Accounts Payable, the payable sits on the Balance Sheet until the business pays the bill.
Depreciation → P&L + Balance Sheet
Depreciation increases expenses on the P&L and increases Accumulated Depreciation on the Balance Sheet at the same time. As we covered in Fixed Assets and Depreciation, this reduces both profit and book value — without touching cash.
Loans → Cash, Liability, Interest, Cash Flow
Borrowing money increases cash and a loan liability on the Balance Sheet. It appears as a financing activity on the Statement of Cash Flows. Later, loan payments create interest expense on the P&L and reduce the loan liability on the Balance Sheet. As we covered in Loans and Debt, one loan touches all three statements.
Ending Cash Connects Back
The ending cash on the Statement of Cash Flows equals the cash balance on the Balance Sheet. The cash flow statement explains how the business got from beginning cash to ending cash. That ending cash is also the cash shown on the Balance Sheet.
Do It
Follow six transactions through the statements. For each one, type the new balances. Watch how one transaction changes the P&L, Balance Sheet, and Cash Activity panels at the same time.
Do It — Follow the Transaction Through the Statements
You are looking at a small business with starting equity of $5,000 (all cash). For each transaction, type the new balance for each affected field. The three panels show how one transaction ripples through the P&L, Balance Sheet, and Cash Activity at the same time.
Only the fields that change are shown for each step. Type the full new balance (not just the change).
Step 1 of 6
Transaction 1:
Invoice a customer for $2,000 (service completed, not yet paid).
Enter the new balance for each field that changes:
Revenue
Previous: $0
Accounts Receivable
Previous: $0
Profit & Loss
Balance Sheet
Cash Activity
Prove It
Answer each question, then read the explanation. There's no score — this is just to help the ideas stick.
Question 1
A business invoices a customer for $2,000. Which statement is affected first, and how?
Question 2
Net income from the P&L flows into which part of the Balance Sheet?
Question 3
A business records $150 of depreciation. How does this single entry affect the statements?
Key Takeaways
- The three financial statements are one system, not separate reports.
- Revenue increases net income, which flows into equity on the Balance Sheet.
- Invoicing creates revenue on the P&L and Accounts Receivable on the Balance Sheet at the same time.
- Bills create expenses on the P&L and Accounts Payable on the Balance Sheet at the same time.
- Depreciation affects the P&L (expense) and the Balance Sheet (accumulated depreciation) without affecting cash.
- Loans affect cash, liabilities, interest expense, and the cash flow statement.
- Ending cash on the cash flow statement equals cash on the Balance Sheet.
- Understanding these connections is what makes a bookkeeper truly understand the books.
