The profit and loss report in Xero shows your business income, expenses and profit over a chosen period. You can run it from the Reports menu, compare periods, drill into any figure, and customise the layout. It is one of the most useful reports for understanding whether your business is actually making money.
You open your Xero profit and loss report, look at the numbers, and feel… roughly nothing. Revenue looks okay. Expenses look higher than you’d like. Net profit is there at the bottom. But what does any of it actually mean — and what should you be doing differently because of it?
This is the situation for most small business owners. They have access to a Xero profit and loss report but no real framework for interpreting it. The numbers exist. The insight doesn’t. This guide changes that.
We’re going to walk through what a P&L report actually contains, how to read each section, which numbers matter most, and how to turn your P&L from a passive record into an active decision-making tool.
What Is a Profit and Loss Report?
A profit and loss report — also called an income statement — shows how much money your business earned and spent over a specific period, and whether you ended up with a profit or a loss. It covers a period of time (a month, a quarter, a financial year) rather than a point in time, which is what distinguishes it from a balance sheet.
The P&L answers one fundamental question: is your business making money? But read properly, it answers a much more useful set of questions: where is the money coming from, where is it going, what are your margins, and are your costs under control?
For Australian business owners, your P&L is also the source document for your income tax return. The net profit figure flows through to your tax return — which means errors in your P&L create errors in your tax obligations. The ATO’s guidance on business income and deductions makes clear that your financial records need to support every figure reported. A P&L that’s coded correctly gives you the evidence trail the ATO expects.
How to Run Your P&L Report in Xero
Running a profit and loss report in Xero takes less than a minute. In the top navigation, go to Accounting, then Reports, and select Profit and Loss. From there, you can set your date range, choose your comparison period (prior month, prior year, or budget), and decide whether to show figures including or excluding GST.
A few settings worth knowing:
- Date range — always check which period you’re looking at. It’s easy to accidentally run a report for the current month when you mean to look at the full financial year.
- Cash vs accrual — Xero lets you toggle between cash basis (transactions recorded when money moves) and accrual basis (transactions recorded when they’re earned or incurred). Accrual gives a more accurate picture of business performance. Cash basis shows your actual cash position. Know which you’re looking at.
- Comparison columns — adding a prior year or prior period column transforms a single P&L into a trend analysis tool. This is where real insights start to emerge.
- Budget variance — if you’ve loaded a budget into Xero, you can compare actuals against budget. This is one of the most powerful things you can do with your P&L.
If you’re working with a bookkeeper, they should be running and reviewing your P&L regularly — typically monthly — and flagging anything that looks unusual before you see it.
Understanding Each Section of Your Xero P&L
Your profit and loss report has a consistent structure. Here’s what each section means and what you should be looking for.
Revenue
Revenue (sometimes called Income or Trading Income) shows everything your business earned during the period. If your Xero chart of accounts has multiple revenue accounts, each will show as a separate line — which lets you see which income streams are growing, which are flat, and which are declining.
Questions to ask here: Is total revenue up or down on the prior period? Which income streams are driving growth? Is the revenue mix shifting in a way that affects your overall margins?
Cost of Sales
Cost of Sales (also called Cost of Goods Sold or COGS) captures the direct costs of producing your product or delivering your service. For a trade business, this might be materials and subcontractor costs. For a product business, it’s the cost of the goods you sell. For some service businesses, it might include direct labour.
Not all businesses have a Cost of Sales section — pure service businesses with no direct variable costs may not use it. But if your business does have direct costs, separating them from operating expenses here is important. It’s what allows you to calculate gross profit.
Gross Profit
Gross profit is Revenue minus Cost of Sales. It represents how much money your business makes from its core activity before you account for the overhead costs of running the business. This is one of the most important numbers on your P&L, and we’ll come back to it when we look at margins.
Operating Expenses
Operating expenses are the costs of running the business that aren’t directly tied to production or delivery. Rent, wages (if not already in Cost of Sales), marketing, insurance, software subscriptions, accounting fees, utilities — these all appear here.
This is where most of the detail lives on a typical P&L, and where you’ll spend most of your analysis time. Look for line items that are unusually high compared to prior periods, expenses that are growing faster than revenue, and costs that you’ve lost track of.
Net Profit
Net profit is what’s left after you subtract all expenses (both cost of sales and operating expenses) from revenue. This is the bottom line — but it’s not the only number that matters. Net profit can be positive while your business is in trouble (if, for example, it’s declining rapidly), and it can look deceptively healthy if it includes one-off gains.
Always look at net profit in context: compared to the prior period, compared to budget, and as a percentage of revenue.
The Two Numbers That Matter Most: Gross Margin and Net Profit Margin
Most business owners focus on absolute figures — “we made $80,000 profit this quarter.” But the most useful way to read a P&L is through margins — profit expressed as a percentage of revenue. Margins let you compare performance across periods, across businesses of different sizes, and against industry benchmarks.
Gross Margin
Gross margin = (Gross Profit ÷ Revenue) × 100
If your revenue is $500,000 and your cost of sales is $300,000, your gross profit is $200,000 and your gross margin is 40%.
Your gross margin tells you how efficiently you’re generating profit from your core activity. A declining gross margin is a serious signal — it means either your costs are rising faster than your prices, your pricing is too low, or the mix of your sales is shifting toward lower-margin products or services.
Gross margin also varies significantly by industry, which is why comparing your margin to industry benchmarks matters. A 30% gross margin is exceptional for a food business but concerning for a professional services firm.
Net Profit Margin
Net profit margin = (Net Profit ÷ Revenue) × 100
Net profit margin tells you what percentage of every dollar of revenue you’re actually keeping as profit after all costs. A 10% net profit margin means for every $100 of revenue, you’re keeping $10.
Low net profit margins leave no room for error — an unexpected cost, a slow month, or a client who doesn’t pay can move you from profit to loss quickly. Understanding your net margin helps you determine how much pricing flexibility you have and how resilient your business is to shocks.
If you want to go deeper on what your margins mean for your business strategy, management accounting is the discipline that turns these numbers into actionable decisions.
Common P&L Mistakes in Xero That Distort Your Numbers
A P&L is only as accurate as the data behind it. These are the most common mistakes that cause Xero P&L reports to produce misleading figures.
Incorrect tax coding
If GST tax codes are applied incorrectly in Xero, your revenue and expense figures on the P&L may be distorted. For example, if a GST-exclusive transaction is coded as GST-inclusive, the revenue figure Xero reports will be understated. Correct tax coding is fundamental — it affects your P&L, your BAS, and your tax return simultaneously.
Personal expenses coded to business accounts
Any personal expense that ends up in your Xero file inflates your operating expenses and reduces your net profit. Worse, it may be claimed as a business deduction when it shouldn’t be. This is a common ATO audit trigger. Keep personal and business expenses completely separate.
Transactions sitting in suspense or unreconciled
Unreconciled bank transactions or transactions sitting in a clearing account distort every section of your P&L. Your revenue may be understated because income hasn’t been allocated, or your expenses may be double-counted. Regular bank reconciliation — ideally weekly — prevents this from building up.
Owner wages coded incorrectly
How you pay yourself matters for your P&L. Sole trader drawings are not an expense and shouldn’t appear in your P&L as one. Director fees for a company are an expense. Getting this wrong distorts your net profit figure and can cause tax errors. If you’re unsure how your drawings or salary should be structured in Xero, your Xero accountant in Melbourne can advise you.
Accrual vs cash confusion
Running your P&L on cash basis when your business operates on accrual (or vice versa) can make your results look very different from reality. If you invoice clients on 30-day terms, a cash basis P&L in a slow collection month will significantly understate your actual revenue. Understand which basis you’re using and be consistent.
How to Use Your P&L to Make Better Decisions
A P&L read passively is wasted. Here’s how to turn it into a decision-making tool.
- Run it monthly, not just annually — annual P&Ls show you what happened. Monthly P&Ls help you respond in time to do something about it.
- Compare to the prior period and prior year — trends matter more than single-period snapshots. Is revenue growing? Are margins holding? Are any expense categories blowing out?
- Set a budget and track variance — without a budget, your P&L tells you what happened but not whether it was good or bad. With a budget loaded into Xero, you can see exactly where you’re over or under — and investigate why.
- Interrogate any line that moves significantly — a cost that was $2,000 last month and $8,000 this month needs an explanation. Drill into that account in Xero to see the transactions behind it.
- Use gross margin to test pricing decisions — if you’re considering a price increase, you can model the gross margin impact before you implement it. If you’re taking on a new type of work, estimate what it would do to your margin.
How Your Accountant Reads Your P&L Differently
When Mina Baselyous and the Pinnacle team review a client’s P&L, we’re not just checking the bottom line. Here’s what a trained eye looks for that most business owners miss.
Ratio analysis. We look at every major expense category as a percentage of revenue — not just in dollars. Wages as a percentage of revenue. Rent as a percentage of revenue. Cost of goods as a percentage of revenue. When these ratios drift, something has changed in the business — and we want to understand what and why.
Comparison to industry benchmarks. We have reference points for typical margins and expense ratios across different industries. When a client’s figures are significantly outside those benchmarks — high or low — it prompts investigation. Sometimes it means the business is performing exceptionally. Sometimes it means something’s being coded incorrectly.
Tax planning signals. A P&L reviewed in May or June is a tax planning tool, not just a historical record. If net profit is coming in significantly higher than expected, there may be legitimate strategies to consider before 30 June. If it’s lower, we need to understand whether that’s a real business performance issue or a timing issue that will resolve itself.
Audit risk flags. Certain patterns in a P&L attract ATO attention — large deductions in specific categories, significant year-on-year fluctuations, or expense-to-revenue ratios that are unusual for the industry. Our management accounting service gives Melbourne business owners this level of ongoing insight.
Frequently Asked Questions
How often should I review my Xero profit and loss report?
At a minimum, monthly. Reviewing your P&L monthly gives you enough frequency to catch problems while there’s still time to act. For businesses in a growth phase, or businesses with tight margins, a fortnightly review is even better. Annual-only reviews are too infrequent to be useful as a management tool — by the time you see an annual P&L, you’ve lost 12 months of decision-making opportunity.
Why does my profit and loss look different on cash basis vs accrual basis?
Cash basis records revenue when payment is received and expenses when payment is made. Accrual basis records revenue when it’s earned (even if unpaid) and expenses when they’re incurred (even if not yet paid). If you have significant outstanding invoices or unpaid bills at the end of a period, the two methods will produce very different results. For most businesses, accrual basis gives a more accurate picture of economic performance, but cash basis can be useful for understanding your actual cash position.
My Xero P&L shows a profit, but I have no cash. What’s going on?
This is one of the most common — and most confusing — situations in small business finance. Profit and cash are not the same thing. You can show a profit on your P&L while having no cash if: your clients haven’t paid their invoices yet, you’ve paid for inventory or equipment that will be used over a longer period, you’ve made loan repayments (which reduce cash but aren’t always shown as an expense), or you’ve paid owner drawings (which don’t appear as an expense on your P&L). Understanding the difference between profit and cash flow is fundamental. Book a call with us if this is a challenge you’re facing — it’s something we can work through quickly.
Start Reading Your P&L Like It Matters — Because It Does
Your Xero profit and loss report contains more useful information about your business than almost any other document you have access to. But only if you read it correctly, regularly, and in context.
The businesses that grow consistently and weather difficult periods are the ones whose owners understand their numbers — not at a surface level, but deeply enough to make decisions based on them. That’s not a finance skill. It’s a business skill. And it’s one we help our clients develop.

Frequently Asked Questions
How do I run a profit and loss report in Xero?
In Xero, go to Accounting or Reports, select Profit and Loss, choose your date range, and run the report. You can compare periods, drill into any line to see the underlying transactions, and customise or save the layout for future use.
What does the Xero profit and loss report show?
It shows your income, cost of sales, gross profit, operating expenses and net profit over the period you choose. Comparing periods reveals trends, and drilling into figures shows exactly which transactions make up each total.
How often should I review my P&L in Xero?
Review it at least monthly. Regular review lets you spot rising costs, shrinking margins or falling sales early, while there is still time to act. Waiting until year end means problems have already affected your bottom line.
Why do my Xero numbers look wrong?
Common causes include unreconciled bank transactions, miscoded expenses, missing bills or invoices, and incorrect GST treatment. Keeping your bank reconciliation up to date and coding transactions correctly keeps the profit and loss accurate and reliable.
