What’s included in my P&L?
Your profit and loss report (P&L) is an essential tool for running a successful business. It shows what you earned, what you spent and what you kept, all within a set period. When you understand how it works, you can see where money is made, where it leaks out and what needs your attention next.
All this means that you shouldn’t just glance at your P&L once a year. Your annual accounts are designed for tax compliance, not day-to-day decisions. A P&L becomes far more powerful when you use it throughout the year, especially when you combine it with real-time data through digital tools like Xero.
What a P&L shows
A P&L breaks down your business performance into a simple structure. Each section builds a picture of how efficiently the business makes money.
Income
This is the total money your business earns from sales excluding VAT. It can include project fees, retainers, recurring revenue and any other trading income. Understanding how your income moves month by month helps you spot seasonality, dependency on just one or two clients, and opportunities to increase capacity or pricing.
Cost of sales
These are the direct costs involved in delivering your services or products. Examples include freelance subcontractors, fee-earning employees, materials, licences purchased specifically for a client job or platform costs tied directly to service delivery. These costs sit above gross profit because they are essential to generating income.
Gross profit
Gross profit is income minus cost of sales. This shows how profitable your core services are before you factor in overheads. If gross profit is tight, the issue is usually pricing, project scope, delivery efficiency or the mix of services you are selling.
Overheads
Overheads are the costs needed to run the business day to day. These can include:
Software and subscriptions
Rent, utilities or co-working costs
Insurance, telecoms and office expenses
Accountancy fees and professional services
Advertising and marketing costs
Tracking overheads through your P&L helps you see whether costs are stable, creeping or taking over more of your margin than they should.
Operating profit
This is gross profit minus overheads. It shows how well the business is performing before tax. For many service-based businesses, this is the key number that indicates whether pricing, utilisation and spending are in balance.
Interest, tax and depreciation
Some P&Ls break these out separately, depending on the software you use. They show the costs of borrowing, the reduction in asset value and the tax recorded for the period. These numbers become more useful when you review them regularly, not once a year.
Net profit
Net profit is the final figure that shows what the business actually kept after all costs. This tells you whether the business is healthy, sustainable and in a position to support your drawings and long-term goals.
Why your P&L matters month to month
A P&L gives you insight into how the business is performing in real time. When you look at it regularly, you can act early rather than react late. You get a clear view of trends like:
Which services are the most profitable
Whether your pricing is working
Whether overheads are rising faster than they should
Whether projects or clients are draining profit
Whether margins are steady or slipping across the year
Month-to-month reviews also help you understand how seasonal patterns, one-off costs or changes in capacity affect performance. It becomes easier to plan for tax, manage cash flow, and decide whether you have room to invest, hire or increase drawings.
When your P&L is accurate and up to date, it becomes one of the most reliable tools for making decisions based on data rather than gut feel.
How to get more value from your P&L
A P&L is most useful when it is used consistently. You get better insight when you:
Review it monthly: A monthly review gives you the clearest trends. You’ll see what is normal for your business and what needs adjusting.
Compare it to previous periods: Patterns become obvious when you compare months, quarters or years. You can track growth, spot problems early and plan for busier or quieter seasons.
Break down income streams: Separate your services to understand which ones are carrying the business and which ones need attention.
Watch margins as closely as revenue: A rise in sales does not always mean a rise in profit. Margin tells you whether the business is becoming more efficient or more expensive to run.
Use real-time bookkeeping: Cloud software allows you to see accurate numbers throughout the month, not weeks after the fact.
What to do next
A clear P&L gives you a straightforward view of how your business earns, spends and keeps money. When you understand each part of the report, decisions become easier and you feel more in control of how the business is performing.
Taking charge starts with confidence in your numbers. Keep the report up to date, review it regularly and look at how income, costs and margins change over time. Each review builds a clearer picture of what’s working and what needs your attention.
