In QuickBooks Online, click on Reports in the left navigation menu. You can either scroll through the list under the Business Overview section or just type “Profit and Loss” in the search bar. Click on the report, set your date range using the dropdown or custom dates, and hit Run Report. That gives you your basic P&L showing revenue, cost of goods sold, gross profit, expenses, and net income for the period you selected.

That gets you the report. But a default P&L with no customization is only marginally useful. The power is in how you adjust it to show you what actually matters.

First, check your accounting method. At the top of the report you can toggle between cash and accrual. Cash basis shows income when money hits your bank account and expenses when money leaves. Accrual shows income when you invoice and expenses when you receive a bill, regardless of when cash moves. Most small business owners look at cash basis for day-to-day decisions, but your tax accountant may want accrual. Know which one you’re looking at or the numbers will confuse you.

Second, add comparison columns. Click Customize, then go to the Rows/Columns section where you can add previous period or previous year comparisons. Seeing this month next to last month, or this quarter next to the same quarter last year, tells you whether things are trending in the right direction. A single month of numbers in isolation doesn’t tell you much.

Third, filter when it makes sense. If you’re using classes or locations in QuickBooks to track different parts of your business, you can filter the P&L to show just one segment. A contractor running three active projects can pull a P&L by project. A business with two locations can see each one separately. This only works if your QuickBooks Online setup was configured properly from the start with the right tracking categories.

Once the report is on screen, look at a few things beyond just the bottom line. What percentage of revenue is going to cost of goods sold? What are your top five expense categories and are any of them growing faster than your revenue? Is your net profit margin where you expect it to be? These are the questions that turn a report into insight.

You can also export the report to Excel or PDF using the export button in the top right corner. This is handy for sharing with your tax accountant or for doing deeper analysis in a spreadsheet.

If your P&L looks wrong or the numbers don’t match what you expected, the issue is almost always in the underlying data. Uncategorized transactions, expenses in the wrong accounts, or missing entries will all make the report unreliable. Working with a QuickBooks ProAdvisor in Chandler can help you get the books cleaned up so the reports you pull actually reflect reality. A P&L is only as good as the data behind it.
