A profit and loss statement, or P&L, summarizes a startup’s revenue, expenses, and profit over a specific period. It can help you spot changes in sales, understand where money is going, and assess whether the business model is working. But a P&L does not show exactly how much cash is in your bank account. Read it alongside your bank activity and cash flow report to make decisions with a clearer view of the business.
Start with the reporting period
Check the dates and accounting method before interpreting any number. A monthly P&L can reveal recent changes, while a year-to-date view shows broader patterns. Compare the same periods when possible, such as this month with the previous month or this quarter with the same quarter last year. Seasonal sales, one-time costs, and a short operating history can make a single period look unusual.
Find out whether the report uses cash-basis or accrual-basis accounting. Under cash-basis accounting, income and expenses are generally recorded when money changes hands. Under accrual accounting, they are generally recorded when earned or incurred, even if payment happens later. This difference affects what appears on the report and how closely its profit figure matches bank activity.
Follow revenue to gross profit
Revenue is the income your business earned from sales or services during the reporting period. Review the categories behind the total, not just the headline number. If sales are split by product, service, or customer type, look for sources that are growing, shrinking, or producing irregular results. Confirm that refunds, discounts, and other adjustments are recorded appropriately so the total reflects business activity clearly.
Next, look at direct costs tied to delivering what you sell, such as materials or costs paid to fulfill a service. Subtracting these costs from revenue gives gross profit. A falling gross profit can signal that direct costs are rising faster than sales, or that pricing and discounts need review. It does not, by itself, explain the cause; compare the underlying costs and sales mix before deciding what to change.
Read expenses and operating profit
Operating expenses are the costs of running the company that are not included in direct delivery costs. Common examples include payroll, rent, software, insurance, and marketing. Review each category for unexpected increases, duplicate charges, or costs that no longer support current priorities. Separate recurring expenses from one-time purchases when analyzing trends, while keeping both in the report so the period’s results remain complete.
After expenses, the P&L shows whether the business earned a profit or recorded a loss for that period. Depending on the report layout, you may see operating profit and a final net profit figure after other income, expenses, taxes, or interest. Check which lines are included before comparing reports. A positive result can support planning, but it does not automatically mean the business has enough cash to cover bills.
Connect profit to cash flow
Profit and cash flow measure different things. A sale recorded as revenue may not have been paid yet, so accounts receivable can rise while cash remains tight. Likewise, paying down a loan principal or buying equipment can reduce cash without appearing as a regular expense in the same way. Timing differences between customer payments and supplier bills can also create a gap between reported profit and available funds.
Use the P&L with a cash flow statement, bank balances, and an accounts receivable and payable review. If revenue and profit are improving but cash is falling, check unpaid invoices, upcoming obligations, inventory or equipment purchases, and debt payments. If results are weaker than expected, identify the categories driving the change and estimate how planned actions may affect cash.

Read a P&L from the reporting period through revenue, direct costs, operating expenses, and profit. Then compare the results with collections, bills, and bank balances to understand what the figures mean for cash. Review the report regularly, investigate meaningful changes, and ask an accounting professional to clarify entries or trends before making major decisions.
