Startup financial statements: P&L, balance sheet and cash flow explained
A startup needs three financial statements every month: a profit and loss, which shows what you earned and spent over the month; a balance sheet, which shows what you own and owe on the last day; and a cash flow statement, which shows how your cash moved. Investors expect all three, usually on an accrual basis, plus burn and runway. Net income links them together.

The short version
- The SEC describes the balance sheet as what a company owns and owes at a fixed point in time, and the income statement as what it made and spent over a period.
- Venture investors typically expect all three statements on an accrual basis for board reporting and fundraising, according to startup accounting firm Kruze Consulting.
- The statements connect: net income from the P&L flows into equity on the balance sheet and starts the cash flow statement, which must end at the balance sheet's cash.
- Burn is how much cash you lose in a month, and runway is cash divided by burn: $658,940 of cash and $41,060 of burn is about 16 months.
- If the balance sheet does not balance, or cash flow does not end at the balance sheet's cash, the books have an error.
Each statement answers one question
The SEC's guide for beginners gives the same split: balance sheets show what a company owns and owes at a fixed point in time, income statements show how much it made and spent over a period, and cash flow statements show the exchange of money between the company and the outside world over a period.
| Statement | Question it answers | Period | What investors look at |
|---|---|---|---|
| Profit and loss (income statement) | Did we make or lose money this month, and why? | A period, such as September | Revenue growth, gross margin, payroll, net loss |
| Balance sheet | What do we own and owe right now? | One day, such as September 30 | Cash, receivables, payables, debt, equity |
| Cash flow statement | Where did our cash actually go? | A period | Cash from operations, burn, runway |
A worked example with numbers that tie together
Take a seed-stage software company in September. It started the month with $700,000 in cash, $6,000 of customer invoices unpaid and $5,000 of bills unpaid.
Revenue: $42,000.
Cost of revenue: hosting $5,800 + merchant fees $1,260 = $7,060.
Gross profit: $34,940 (83% of revenue).
Operating expenses: payroll $58,000 + software $4,200 + marketing $6,500 + legal and professional $3,300 + other $2,000 = $74,000.
Net loss: $34,940 − $74,000 = $(39,060).
The cash differs from the loss because of timing. Customers owe $12,000 at the end of the month, up $6,000, so $6,000 of revenue has not become cash. The company owes $9,000 in bills, up $4,000, so $4,000 of expense has not been paid.
The balance sheet and cash flow statement use the same month
Assets: cash $658,940 + accounts receivable $12,000 = $670,940.
Liabilities: accounts payable $9,000.
Equity: paid-in capital $1,200,000 − accumulated deficit $538,060 = $661,940. The deficit grew from $499,000 by the $39,060 loss.
Liabilities plus equity: $9,000 + $661,940 = $670,940, which equals total assets.
Cash flow from operations: net loss $(39,060) − receivables increase $6,000 + payables increase $4,000 = $(41,060). Investing and financing: $0.
Cash: $700,000 − $41,060 = $658,940, the balance sheet's cash.
Net burn for the month is $41,060. Runway is $658,940 ÷ $41,060, about 16 months at this rate. Because these statements are on an accrual basis, burn is easiest to read from the cash flow statement, which shows actual cash.
What investors ask for, and in what form
- All three statements, monthly, on an accrual basis. Kruze Consulting says venture investors typically expect this for board reporting and fundraising.
- Burn and runway, which the balance sheet's cash and the cash flow statement produce.
- Gross margin and payroll as a share of spend, from the P&L.
- The support behind the numbers: the general ledger, bank statements and the documents behind large entries.
If you keep cash books today, plan the move to accrual before you raise. See bookkeeping for startups for the choice. The burn rate and runway guides cover the two numbers investors compute first.
Three checks that catch an error in any set of statements
Step 1: The balance sheet balances: total assets equal total liabilities plus equity, every month.
Step 2: Net income on the P&L equals the change in equity. In the example, a loss of $39,060 grows the deficit from $499,000 to $538,060.
Step 3: The cash flow statement starts at net income and ends at the balance sheet's cash.

Questions founders ask
What financial statements does a startup need?
Three: a profit and loss, a balance sheet and a cash flow statement, produced every month. Investors and your CPA ask for all three.
What is the difference between a P&L and a balance sheet?
A P&L covers a period and shows revenue, expenses and net income. A balance sheet is a snapshot on one day of assets, liabilities and equity.
Do startups use cash or accrual for financial statements?
Venture investors typically expect accrual-basis statements. Early startups often keep cash books and switch before or at their first raise.
What is the difference between burn and net loss?
Net loss is the P&L result and includes non-cash timing. Burn is the cash that left the company in the month, so it comes from the cash flow statement.
How often should a startup produce financial statements?
Monthly, once the month is closed and every account matches its bank statement.
